Directive 97/24/EC of the European Parliament and of the Council of 17 June 1997 on certain components and characteristics of two or three-wheel motor vehicles  


Official Journal L 226 , 18/08/1997 P. 0001 - 0454 





DIRECTIVE 97/24/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 17 June 1997 on certain components and characteristics of two or three-wheel motor vehiclesTHE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,Having regard to the Treaty establishing the European Community, and in particular Article 100a thereof,Having regard to the proposal from the Commission (1),Having regard to the opinion of the Economic and Social Committee (2),Acting in accordance with the procedure laid down in Article 189b of the Treaty (3) in the light of the joint text approved by the Conciliation Committee on 4 February 1997,(1) Whereas it is necessary to adopt measures that are intended to ensure the operation of the internal market;(2) Whereas, in each Member State, two or three-wheel motor vehicles must, in respect of the components and characteristics covered by this Directive, satisfy certain mandatory technical requirements which differ from one Member State to another; whereas, owing to those differences, such requirements constitute barriers to trade within the Community; whereas those barriers to the operation of the internal market may be removed if the same requirements are adopted by all of the Member States in place of their national regulations;(3) Whereas the drawing-up of harmonized requirements concerning those components and characteristics of two and three-wheel motor vehicles is necessary in order to enable the type-approval and component type-approval procedures covered by Council Directive 92/61/EEC of30 June 1992 relating to the type-approval of two or three-wheel vehicles (4) to be implemented in respect of each type of the aforesaid vehicles;(4) Whereas, in order to facilitate access to markets in third countries, it appears necessary to establish equivalence between the requirements of Chapters 1 (tyres), 2 (lighting and light-signalling devices), 4 (rear-view mirrors) and 11 (safety belts) of the Annex to this Directive and those of United Nations ECE Regulations Nos 30, 54, 64 and 75 in respect of tyres, 3, 19, 20, 37, 38, 50, 56, 57, 72 and 82 in respect of lighting and light-signalling devices, 81 in respect of rear-view mirrors and 16 in respect of safety belts;(5) Whereas, with regard to the aspects concerning the protection of the environment, namely atmospheric and noise pollution, it is necessary to pursue the aim of constantly improving the environment; whereas, for this purpose, limit values for pollutants and sound level must be laid down for the fastest possible application; whereas subsequent reductions in the limit values and changes in the testing procedure may be decided upon only on the basis of studies and research to be undertaken or pursued into the available or conceivable technological potential and into an analysis of their cost/benefit ratios in order to permit production, on an industrial scale, of vehicles which are able to meet these more stringent limits; whereas the decision on that subsequent reduction must be taken by the European Parliament and the Council at least three years before these limit values enter into force in order to enable the industry to take the necessary measures whereby their products may, by the intended date, comply with the new Community provisions; whereas the Decision of the European Parliament and of the Council will be based on proposals to be submitted by the Commission in due course;(6) Whereas, pursuant to the provisions of Directive 92/61/EEC, the components and characteristics covered by this Directive may not be placed on the market and sold in the Member States unless they comply with the provisions of this Directive;whereas the Member States must take all the necessary measures to ensure fulfilment of the obligations resulting from this Directive.(7) Whereas Member States should be enabled, by granting tax incentives, to promote the marketing of vehicles which, in advance, meet the requirements adopted at Community level concerning measures to counter pollutant and noise emissions;(8) Whereas the methods of measuring the immunity of vehicles and separate technical units to electromagnetic radiation in order to check compliance with the provisions concerning electromagnetic compatibility (Chapter 8) require complex and costly installations; whereas, in order to enable Member States to provide such installations, provision should be made for deferring application of these measuring methods by three years from the entry into force of this Directive;(9) Whereas, given the scale and impact of the action proposed in the sector in question, the Community measures which are the subject of this Directive are necessary, or even indispensable, to attain the objectives set, namely Community vehicle type approval; whereas these objectives cannot be adequately achieved by the Member States individually;(10) Whereas technical progress requires rapid adaptation of the technical requirements set out in the Annex to this Directive; whereas, with the exception of the limit values for pollutants and sound level, this task should be assigned to the Commission in order to simplify and speed up the procedure; whereas, in all cases where the European Parliament and the Council confer upon the Commission authority to implement rules laid down in the two or three-wheel motor vehicle sector, it is appropriate to provide for a procedure for prior consultation between the Commission and Member States within a committee;(11) Whereas safety or environmental requirements call for restrictions on tampering with certain types of two or three-wheel vehicle; whereas, if they are not to prove an obstacle to owner servicing and maintenance, such restrictions must be strictly limited to tampering which significantly modifies the vehicle's performance and pollutant and noise emissions;(12) Whereas, a long as vehicles conform to the requirements of this Directive, no Member State may refuse registration or use of them; whereas the object of the requirements of this Directive should not be to oblige those Member States which do not allow two or three-wheel motor vehicles in their territory to tow a trailer to amend their rules,HAVE ADOPTED THIS DIRECTIVE:Article 1 This Directive and its Annex shall apply to:- tyres,- lighting and light-signalling devices,- external projections,- rear-view mirrors,- measures to counter air pollution,- fuel tanks,- measures to counter tampering,- electromagnetic compatibility,- permissible sound level and exhaust systems,- coupling devices and attachments,- safety belt anchorages and safety belts,- glazing, windscreen wipers and washers and de-icing and demisting devices,for all types of vehicles as defined in Article 1 of Directive 92/61/EEC.Article 2 Within three years following the date referred to in the third subparagraph of Article 8 (1), the Commission shall carry out a detailed study to ascertain whether the anti-tampering measures for vehicles, particularly those in categories A and B referred to in Chapter 7 of the Annex to this Directive, can be considered appropriate, inadequate or too extreme in light of the intended aims. In the basis of the conclusions of the study, the Commission will, if necessary, propose new legislative measures.Article 3 1. The procedures governing the granting of component type-approval in respect of tyres, lighting and light-signalling devices, rear-view mirrors, fuel tanks, exhaust systems, safety belts and glazing for a type of two or three-wheel motor vehicle and the component type approval of a type of tyre, lighting and light-signalling device, rear-view mirror, fuel tank, exhaust system, safety belt and glazing, in the form of components, and the conditions applying to the free movement of such vehicles and for the free placing on the market of components shall be those set out in Chapters II and III respectively of Directive 92/61/EEC.2. The procedure governing the granting of component type-approval in respect of external projections, measures to counter air pollution, measures to counter tampering, electromagnetic compatibility, permissible sound level, coupling devices for trailers and sidecar attachments, safety belt anchorages, windscreen wipers and washers and de-icing and demisting devices for a type of two or three-wheel motor vehicle, and the conditions applying to the free movement of such vehicles, shall be those set out in Chapters II and III respectively of Directive 92/61/EEC.Article 4 1.

The Member States' authorities granting component type approval shall accept component type approvals issued in accordance with the requirements of the Regulations referred to in paragraph 1, and component type-approval marks, instead of the corresponding component type approvals and componenttype-approval marks issued in accordance with the requirements of this Directive.Article 5 1. Within 24 months from the date of adoption of this Directive, the Commission shall submit to the European Parliament and to the Council a proposal prepared on the basis of research and an assessment of the costs and benefits deriving from the application of tightened-up limit values and laying down a subsequent stage during which measures will be adopted aimed at further tightening of the limit values for pollutants and the sound level of the vehicles concerned, as laid down respectively in Chapter 5, Annex II, Tables I and II and Chapter 9, Annex I. In its proposal, the Commission shall take into account and assess the cost-effectiveness of the various measures for reducing pollutant and noise emissions and shall present proportionate and reasonable measuring having regard to the intended aims.2. The Decision of the European Parliament and of the Council, adopted on the basis of the Commission proposal referred to in paragraph 1, which shall be adopted by 1 January 2001, shall take account of the need to incorporate factors other than simply limit values which have been tightened up. The costs and benefits deriving from the implementation of the measures provided for in the said Decision shall be researched and assessed, jointly with interested parties such as industry, users and groups representing consumers or the public and these shall be proportionate and reasonable in the light of the intended aims.Article 6 1. Member States may make provision for tax incentives only for motor vehicles conforming to the air-pollution and noise-pollution measures laid down in Chapter 5, Annex I, section 2.2.1.1.3 and Annex II, Tables I and II and Chapter 9, Annex I respectively of this Directive.2. The incentives referred to in paragraph 1 must be in line with the provisions of the Treaty and meet the following conditions:- they shall be valid for all new vehicles placed on the market of a Member State which, in advance, comply with the requirements of this Directive referred to in paragraph 1,- they shall cease upon the mandatory implementation of the measures referred to in paragraph 1,- they shall, for each type of motor vehicle, involve lower amounts than the extra cost of the technical solutions applied and of their incorporation into the motor vehicle to enable the values laid down to be met.3. The Commission shall be informed in good time of any intentions to introduce or alter any of the tax incentives referred to in paragraph 1, so that it can submit its comments.Article 7 The changes needed:- to take into account any amendments to the United Nations ECE Regulations referred to in Article 4,- to adapt the Annex to technical progress - apart from the limit values for air and noise pollution set out in Chapter 5, Annex I, section 2.2.1.1.3, and Annex II, Tables I and II, and in Chapter 9, Annex I respectively,shall be adopted in accordance with the procedure laid down in Article 13 of Council Directive 70/156/EEC of 6 February 1970 on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers (21).Article 8 1. Member States shall bring into force the laws, regulations and administrative provisions necessary to comply with this Directive before 18 December 1998. They shall forthwith inform the Commission thereof.From the date referred to in the first subparagraph, Member States may no longer prohibit the first entry into service of vehicles complying with the provisions of this Directive or of certain of its chapters.They shall apply these provisions from 17 June 1999.However, the implementation of certain provisions in Chapters 5, 8 and 9 shall be deferred as specified in the said chapters.2. When Member States adopt the measures referred to in paragraph 1, they shall contain a reference to this Directive or shall be accompanied by such reference on the occasion of their official publication. The methods of making such reference shall be laid down by Member States.Article 9 1. Council Directive 80/780(EEC of 22 July 1980 on the approximation of the laws of the Member States relating to rear-view mirrors for two-wheeled motor vehicles with or without a side-car and to their fitting on such vehicles (22) shall be repealed when this Directive becomes applicable.2. However, components for which approvals as laid down in Annex I to the Directive referred to in paragraph 1 have been granted may continue to be used.3. Council Directive 78/1015/EEC of 23 November 1978 on the approximation of the laws of the Member States on the permissible sound level and exhaust system of motorcycles (23) shall be repealed on the date referred to the first subparagraph of Article 8.4. Until the date referred to in the first subparagraph of Article 8 (1), approvals as referred to in Directive 78/1015/EEC may be granted for type approvals of vehicles referred to in Directive 92/61/EEC. The limit values laid down for noise levels in Annex I, section 2.2.1 of Directive 78/1015/EEC shall apply.Article 15 (4) (c) of Directive 92/61/EEC shall therefore apply when such vehicles are first put into service.5. On the entry into force of this Directive, the provisions of Council Directive 89/336/EEC of 3 May 1989 on the approximation of the laws of the Member States relating to electromagnetic compatibility (24) shall cease to apply to vehicles covered by this Directive.Article 10 This Directive shall enter into force on the day of its publication in the Official Journal of the European Communities.Article 11 This Directive is addressed to the Member States.Done at Brussels, 17 June 1997.For the European ParliamentThe PresidentJ.

The wheel/tyre combination shall be stored at the temperature of the test room for at least three hours.3.6. Following that period of storage the inflation pressure shall be corrected to the value laid down in Item 3.4.1.3.7. The wheel/tyre combination shall be mounted on the test axle and checked to ensure that it turns freely. The tyre may be rotated by a motor acting on the test axle or else via pressure against a test drum.3.8. The entire assembly shall be accelerated without interruption in order to achieve, within five minutes, the maximum speed capability of the tyre.3.9. The contour-outline device shall be installed, care being taken to ensure that it is at right angles to the (direction of) rotation of the tread of the tyre being tested.3.10. A check shall be made that the peripheral speed of the tread surface is equal to the maximum speed capability of the tyre ± 2 %. The equipment shall be kept at a constant speed for five minutes at least and then the cross section of the tyre shall be traced in the area of maximum deformation or a check should be made that the tyre does not exceed the enveloping curve.4. ASSESSMENT OF RESULTS4.1. The envelope of the tyre/wheel assembly shall be as in the example below.>REFERENCE TO A GRAPHIC>With reference to items 3.1.4 and 3.1.5 in this Annex, the limit values for the envelope outline are laid down as follows:>TABLE>4.1.1.

COMPONENT TYPE-APPROVAL OF A DEVICE4.1. When at least two devices form part of the same device component type-approval can be granted only if each of those devices meets the requirements of this Chapter.5. MINIMUM REQUIREMENTS FOR CONFORMITY OF PRODUCTION CONTROL PROCEDURES5.1. General5.1.1. The conformity requirements are considered satisfied from a mechanical and geometric standpoint, if the differences do not exceed inevitable manufacturing deviations within the requirements of this Directive.5.1.2. With respect to photometric performances, the conformity of series-produced devices must not be contested if, when testing photometric performances of any device chosen at random and in the case of signalling lamps, headlamps or front fog-lamps equipped with standard filament-lamps, no measured value deviates unfavourably by more than 20 % from the minimum values prescribed in this Directive.5.1.3. If the results of the test described above do not meet the requirements, in the case of signalling lamps, headlamps or front fog-lamps, tests on devices must be repeated using another standard filament-lamp.5.1.4. Devices with apparent defects are disregarded.5.1.5. The trichromatic coordinates must be complied with in the case of signalling lamps, headlamps or front fog-lamps when these are equipped with filament lamps set to Standard A colour temperature.5.2. Minimum requirements for verification of conformity by the manufacturerFor each type of device the holder of the approval mark must carry out at least the following tests at appropriate intervals. The tests must be carried out in accordance with the provisions of this Directive.If any sampling shows non-conformity with regard to the type of test concerned, further samples are taken and tested. The manufacturer must take steps to ensure the conformity of the production concerned.5.2.1. Nature of testsTests of conformity to this Directive must cover the photometric and colorimetric characteristics for headlamps of motorcycles and tricycles and the verification of the change in vertical position of the cut-off line under the influence of heat.5.2.2. Methods used in tests5.2.2.1. Tests must generally be carried out in accordance with the methods set out in this Directive.5.2.2.2. In any test of conformity carried out by the manufacturer, equivalent methods may be used with the consent of the competent authority responsible for approval tests. The manufacturer is responsible for proving that the methods applied are equivalent to those laid down in this Directive.5.2.2.3. The application of 5.2.2.1 and 5.2.2.2 requires regular calibration of test apparatus and its correlation with measurements made by a competent authority.5.2.2.4. In all cases, the reference methods must be those laid down in this Directive, particularly for the purpose of administrative verification and sampling.5.2.3. Nature of samplingSamples of devices are selected at random from the production of a uniform batch. A uniform batch means a set of devices of the same type, defined according to the production methods of the manufacturer.The assessment must in general cover series production from individual factories. However, a manufacturer may group together records concerning the same type from several factories, provided these operate under the same quality system and quality management.5.2.4. Measured and recorded photometric and colorimetric characteristicsThe sampled device is subjected to photometric measurements at the points provided for in the relevant Annexes unless otherwise prescribed. The trichromatic coordinates must be complied with.5.2.5. Criteria governing acceptabilityThe manufacturer is responsible for carrying out a statistical study of the test results and for defining, in agreement with the competent authority, criteria governing the acceptability of his products, in order to meet the specifications laid down for the verification of conformity of products in Annex VI to Directive 92/61/EEC.The criteria governing the acceptability must be such that, with a confidence level of 95 %, the minimum probability of passing a spot check in accordance with section 6 (first sampling) would be 0,95.6.

STANDARDIZED TABLE SHOWING SPATIAL DISTRIBUTION OF LIGHT >REFERENCE TO A GRAPHIC>2.1. Direction H = 0° and V = 0° corresponds to the axis of reference (on the vehicle it is horizontal and parallel to the median longitudinal plane of the vehicle and pointing towards the required field of view). It passes through the centre of reference. The values set out in the table give the minimum intensities for the various directions of measurement as a percentage of the minimum required for each lamp within the axis (in direction H = 0° and V = 0°).2.2. Within the field of light distribution represented in diagrammatic form in section 2 by a grid, the distribution of the light must essentially be uniform in such a way that the light intensity in each direction of a part of the field formed by the lines of the grid reaches at least the lowest minimum value specified as a percentage (or the lowest available value) on the lines of the grid which surround the direction at issue.3.

For replaceable filament lamps:when equipped with mass-production filament lamps at 6,75 V, 13,5 V or 28,0 V the luminous intensity values produced must lie between the maximum limit and the minimum limit given in this Annex increased in accordance with the permissible deviation of the luminous flux permitted for the type of filament lamp chosen, as stated in Annex IV for production filament lamps; alternatively a standard filament lamp may be used in turn, in each of the individual positions, operated at its reference flux, the individual measurements in each position being added.Appendix 3 Photometric measurements of the rear registration-plate illuminating device1. POSITION TO BE ILLUMINATED Devices may fall within category 1 or 2. The category 1 devices must be designed in such a way as to illuminate a position measuring at least 130 × 240 mm and the category 2 devices in such a way as to illuminate a position measuring at least 200 × 280 mm.2.

LIGHT INCIDENCE The manufacturer of the illuminating device must lay down the conditions for the fitting of the device in relation to the position intended for the registration plate. That device must occupy a position such that at none of the points on the surface to be illuminated with the angle of incidence of the light on the surface of the plate exceed 82°, that angle being measured in relation to the extremity of the light-emitting surface of the device that is furthest from the surface of the plate. Where there is more than one optical component this requirement applies only to the part of the plate intended to be illuminated by the relevant component.The device must be designed in such a manner that no ray of light shines directly towards the rear with the exception of rays of red light where the device is combined or grouped with a rear lamp.4. METHOD OF MEASUREMENT The levels of luminance are measured on a sheet of clean white blotting paper having a minimum factor of diffuse reflection of 70 % and the same dimensions as the registration plate and placed at the position it would normally occupy but 2 mm in front of its support.The level of luminance is measured at right angles to the surface of the paper at the points shown in the diagram in section 5 below, each point representing a circular area 25 mm in diameter.5.

ADDITIONAL REQUIREMENTS CONCERNING MARKS AND THE MARKING OF SPECIFIC DEVICES1.1. Headlamps must bear in a clearly legible and indelible manner the letters 'MB` (symbol for driving-beam headlamp) opposite the component type-approval number.1.2. All headlamps designed in such a way as to preclude any simultaneous lighting-up of the passing-beam filament and that of any other light source with which they may be integrated may be marked with an oblique stroke (/) following the symbol (MB) for the passing beam in the component type-approval mark.1.3. On headlamps incorporating a lens of plastic material, the letters 'PL` must be affixed near the symbol prescribed in 1.1.2. GENERAL REQUIREMENTS2.1. Each of the samples must meet the specifications set out in section 3 below.2.2. Headlamps must be designed and manufactured in such a way that, under normal conditions of use and despite any vibrations to which they may be exposed, they continue to function properly and retain the required characteristics.2.2.1. Headlamps must be fitted with a device enabling them to be adjusted on the vehicle in accordance with the rules applying to them. A device of this type may be dispensed with where headlamp units consists of a reflector and lens which cannot be separated where the use of units of this type is restricted to vehicles on which the headlamps are adjusted by other means.If headlamps specifically designed for driving-beam operation and headlamps specifically designed for passing-beam operation, each of which has an individual lamp, are grouped together or reciprocally incorporated in a single device, the setting device must enable each of the optical systems to be adjusted individually in order to achieve the official settings.2.2.2. However, these provisions do not apply to headlamp assemblies whose reflectors are indivisible. For this type of assembly the requirements set out in section 3.3 apply. Where more than one light source is used to provide the main beam, the combined functions must be used to determine the maximum value of the illumination (Emax).2.3. The parts intended to attach the filament lamp must be made in such a way that, even in the dark, the filament lamp can be attached without uncertainty in its appropriate position.2.4. Additional tests meeting the requirements of Appendix 2 must be carried out in order to ensure that there are no excessive variations in photometric performance during use.2.5. If the lens of the headlamp is of plastic material, additional tests must be carried out in accordance with the requirements of Appendix 3.3. SPECIFIC REQUIREMENTS3.1. The correct position of the lens in relation to the optical system must be clearly marked and locked in position in order to prevent rotation during use.3.2. In order to check the illumination produced by the headlamp a measuring screen as described in Appendix 1 is used, together with a standard lamp (S1 and/or S2, see Annex IV) having a smooth colourless filament lamp.Standard lamps must be adjusted to the relevant reference light flux applying in accordance with the values required for such lamps.3.3. The passing beam must produce a cut-off of such sharpness that correct adjustment by means thereof is a practical possibility. The cut-off must be as straight and as horizontal as possible over a horizontal length of at least ± 5°. When adjusted in accordance with Appendix 1 headlamps must meet the conditions set out therein.3.4. The light distribution must not vary in lateral terms in a way that impairs good visibility.3.5. The illumination on the screen referred to in 3.2 must be measured by means of a functioning-surface photocell lying within a 65 mm square.4. ADDITIONAL REQUIREMENTS APPLYING TO ANY INSPECTIONS WHICH MAY BE CARRIED OUT BY THE COMPETENT AUTHORITIES WHEN CHECKING CONFORMITY OF PRODUCTION IN ACCORDANCE WITH SECTION 5.1 OF ANNEX I4.1. For value in zone III, the maximum unfavourable deviation may be respectively:- 0,3 lux equivalent 20 %- 0,45 lux equivalent 30 %.4.2. if, for the driving beam, HV being situated within the isolux 0,75 Emax, a tolerance of + 20 % for maximum values and - 20 % for minimum values is observed for the photometric values at any measuring point specified in sections 4.3 and 4.4 of Appendix 1 to this Directive.4.3. With respect to the verification of the change in the vertical position of the cut-off line under the influence of heat, the following procedure is applied:One of the sampled headlamps is tested in accordance with the procedure described in section 2.1 of Appendix 2 after being subjected three consecutive times to the cycle described in section 2.2.2 of Appendix 2.The headlamp is considered to be acceptable if Är does not exceed 1,5 mrad.If this value exceeds 1,5 mrad but is not more than 2,0 mrad, a second headlamp is subjected to the test, after which the mean of the absolute values recorded on both samples may not exceed 1,5 mrad.Appendix 1 Photometric tests1. For adjustment purposes the relevant screen must be placed at least 10 m before the headlamp, line h-h being horizontal. For the measurements the photocell must be 25 m in front of the headlamp and at right angles to the line joining the incandescent filament lamp and point HV.2. In lateral terms the headlamp must be aligned in such a way that the distribution of the driving beam is symmetrical in relation to line v-v.3. In vertical terms the headlamp must be adjusted in such way that the passing beam cut-off is 250 mm below line h-h (at a distance of 25 m).4. When the headlamp has been adjusted in accordance with sections 2 and 3, conditions for which are similar to those relating to driving beams, the following conditions must be met:4.1. the lighting centre of the driving beam must not be more than 0,6° above or below line h-h;4.2. the illumination provided by the driving beam must reach its maximum value (Emax) at the centre of the entire light distribution and diminish laterally;4.3. the maximum illumination (Emax) of the driving beam must be at least 32 lux;4.4. the illumination produced by the driving beam must correspond to the following values:4.4.1. the point of intersection between lines h-h and v-v HV must lie within the isolux for 90 % of maximum illumination.4.4.2. starting from HV horizontally to the right and left the illumination provided by the driving beam must be at least 12 lux up to a distance of 1,125 m and not less than 3 lux up to a distance of 2,25 m.4.5.

ADDITIONAL REQUIREMENTS CONCERNING MARKS AND THE MARKING OF DEVICES1.1. Headlamps designed in such a way as to meet the requirement of a single rule of the road (driving on either the right or the left) must, on the lens, bear the limits of the area which may possibly be masked in order to avoid distracting road users in a country where the rule of the road is not that for which the headlamp has been designed. However, when that area is directly identifiable by design any such delimitation is not necessary.1.2. Headlamps designed in such a way as to meet the requirements of driving on the right and those for driving on the left must bear markings in order to locate the two positions for the fixing in position of the light unit on the vehicle or the lamp on the reflector; these markings consist of the letters 'R/D` for the position corresponding to driving on the right and the letters 'L/G` for the position corresponding to driving on the left.1.3. All headlamps designed in such a way as to preclude any simultaneous lighting-up of the dipped-beam filament and that of any other light source with which they may be associated must be marked with an oblique stroke (/) within the component type-approval mark, after the passing beam headlamp symbol.1.4. Where headlamps meet only the requirements of driving on the left, a horizontal arrow pointing to the right of an observer looking at the headlamp head on, i.e. towards the side of the road driven upon, must be entered below the component type-approval mark.1.5. Where, by means of a deliberate alteration in the adjustment of the light unit or lamp, headlamps meet the requirements of both rules of the road, a horizontal arrow having two tips pointing one to the left and the other to the right must be entered below the component type-approval mark.1.6. The letters 'MBH` on headlamps with HS1 lamps are placed opposite the component type-approval mark.1.7. The marks and symbols referred to above must be clearly visible and indelible.1.8. On headlamps incorporating a lens of plastic material, the letters 'PL` must be affixed near the symbols prescribed in 1.2 to 1.7.2. GENERAL REQUIREMENTS2.1. Each of the samples must meet the specifications set out in sections 3 to 5.2.2. Headlamps must be designed and manufactured in such a way that under the normal conditions of use and despite any vibrations to which they may be exposed they continue to function properly and retain the characteristics required by this Annex.2.2.1. Headlamps must be fitted with a device enabling them to be adjusted on the vehicle in such a way as to meet the rules applying to them. This said device does not need to be attached to the parts within which the reflector and diffuser lens cannot be separated, provided that the use of those parts is restricted to vehicles on which the headlamps may be adjusted by other means.Where a headlamp emitting a driving beam and a headlamp emitting a passing beam, each being equipped with its own lamp, are grouped together to form a composite unit, the setting device must enable each individual optical system to be set in an appropriate manner.2.2.2. However, these provisions do not apply to headlamp assemblies whose reflectors are indivisible. In this instance the requirements of section 2 of this Annex shall apply. When more than one light source provides the driving beam those sources must be combined in order to determine the maximum illumination value (Emax).2.3. The parts intended to attach the filament lamp to the reflector must be made in such a way that, even in the dark, the filament lamp can be attached without uncertainty in its appropriate position.2.4. The correct position of the lens in relation to the optical system must be clearly marked and locked in position in order to avoid any rotation.2.5. Where headlamps have been designed in such a way as to meet the requirements of driving on both the right and the left, adaptation to a given rule of the road may be obtained by a suitable initial setting when the vehicle is equipped or via a deliberate action on the part of the user. That initial setting or that deliberate action must, for example, consist of a specific angular setting either of the sealed-beam assembly on the vehicle or of the lamp in relation to that assembly. In all cases only two different setting positions that have been clearly specified and correspond in each case to a rule of the road (driving on the right or left) must be possible and any shift into an intermediate position must be made impossible. When the lamp is able to occupy two different positions the parts intended to attach the lamp to the reflector must be designed and manufactured in such a way that, in each of those two positions, the lamp is attached with the same precision as required for headlamps designed for just one rule of the road. Conformity must be checked visually and, where appropriate, by means of a test assembly.2.6. In order to ensure that operation does not involve any excessive variation in photometric performance, additional tests must be carried out as required by Appendix 2.2.7. If the lens of the headlamps is of plastic material, additional tests must be carried out in accordance with the requirements of Appendix 3.3. ILLUMINATION REQUIREMENTS3.1. General requirements3.1.1. Headlamps must be designed in such a way that, with adequate HS1 or R2 lamps, they emit a light that is not dazzling but is nevertheless adequate on passing beam and provides good illumination on driving beam.3.1.2. A screen placed vertically at a distance of 25 m in front of the headlamp, as shown in Appendix 1, must be used to check the illumination produced by the headlamp.3.1.3. A colourless reference lamp designed for a nominal voltage of 12 V must be used in examining headlamps. The current at the terminals of the lamp during examination of the headlamp must be set to the following characteristics:>TABLE>>TABLE>The headlamp must be considered acceptable if it meets the requirements set out in section 3 with at least one reference lamp which may be presented together with the headlamp.3.1.4. The dimensions determining the position of the filaments within the HS1 or R2 filament reference lamp are set out in Annex IV.3.1.5. The bulb for the filament reference lamp must be of such a shape and optical quality that it causes a minimum of reflection or refraction which may have an adverse effect on the light distribution.3.2. Requirement relating to the passing beam3.2.1. The passing beam must produce a cut-off of such distinctness that it is possible to carry out adjustments correctly using the said cut-off. The cut-off must be a straight horizontal line on the side opposite to the rule of the road for which the headlamp is intended. On the other side the cut-off must not go beyond either broken line HV-H1 and H4 formed by a straight line formed by HV-H1 lying at an angle of 45° with the horizontal and a straight line H1-H4 offset by 1 % in relation to straight line h-h, or straight line HV-H3 inclined by 15° to the horizontal (see Appendix 1). In no case is a cut-off going beyond both line HV-H2 and line H2-H4 and resulting from the combination of the two preceding possibilities acceptable.3.2.2. The headlamp must be aligned in such a way that:3.2.2.1. where headlamps are designed to meet the requirements of driving on the right the cut-off on the left-hand half of the screen must be horizontal and for headlamps designed to meet the requirements of driving on the left the cut-off in the right-hand half of the screen must be horizontal. The setting screen must be sufficiently wide to permit examination of the cut-off over at least 5° on each side of line v-v;3.2.2.2. on the screen this horizontal part of the cut-off must be 25 cm below the horizontal plane passing through the focal centre of the headlamp (see Appendix 1);3.2.2.3. the tip of the cut-off must be on straight line v-v. If the beam does not have a cut-off, a clear 'elbow` lateral setting must be presented in such a way as best to meet the illumination requirements applying to points 75 R and 50 R for driving on the right and point 75 L and 50 L for driving on the left.3.2.3. When aligned in this manner the headlamp must meet the requirements referred to in 3.2.5 to 3.2.7 and 3.3.3.2.4. Where a headlamp aligned as referred to above does not meet the requirements of 3.2.5 to 3.2.7 and 3.3 it is permissible to alter the setting provided that the axis of the beam is not moved sideways by more than 1° (= 44 cm) to the right or left. The incorrect setting limit of 1° to the right or left is not compatible with a vertical incorrect setting upwards or downwards which is restricted only by the requirements laid down in 3.3. However, the horizontal part of the cut-off must not go beyond line h-h. In order to make settings easier by means of the cut-off it is permissible partly to mask the headlamp in order to make the cut-off more distinct.3.2.5. The illumination produced on the screen by the passing beam must meet the requirements set out in the following table:>TABLE>3.2.6. In none of the zones I, II, III and IV must there be lateral variations that impair good visibility.3.2.7. Headlamps designed to meet the requirements of driving on the right and those for driving on the left must, for each of the two locations of the sealed beam unit or lamp meet the requirements set out above for the rule of the road corresponding to the location under consideration.3.3. Requirements concerning the driving beam3.3.1. The illumination produced on the screen by the driving beam must be measured using the same headlamp setting as for the measurements defined in 3.2.5 to 3.2.7.3.3.2. The illumination produced on the screen by the driving beam must meet the following requirements:3.3.2.1. Point of intersection HV of lines h-h and v-v must be at the isolux representing 90 % of maximum illumination. Maximum value Em must be at least 32 lux. Its value must not exceed 240 lux.3.3.2.2. Starting from the HV point horizontally to the right and to the left, the illumination must be at least 16 lux at a distance of 1,125 m and at least equal to 4 lux up to a distance of 2,25 m.3.4. The illumination on the screen referred to in 3.2.5 to 3.2.7 and 3.3 must be measured by means of a useable-area photo receiver acting within a 65 mm square.4. REFERENCE HEADLAMPA headlamp which:4.1. meets the component type-approval requirements set out below;4.2. has an effective diameter of at least 160 mm;4.3. provides illumination, with a reference lamp, at various points within the various areas provided for in 3.2.5;4.3.1. which is at least 90 % of the maximum values, and4.3.2. at least 120 % of the minimum limits as required by the table in 3.2.5, is considered to be a reference headlamp.5. ADDITIONAL REQUIREMENTS ATTACHED TO ANY INSPECTIONS WHICH MAY BE CARRIED OUT, BY THE COMPETENT AUTHORITIES WHEN CHECKING CONFORMITY OF PRODUCTION ACCORDING TO SECTION 5.1 OF ANNEX I5.1. For values B 50 L (or R) and Zone III the maximum deviation may be respectively>TABLE>5.2. For the passing beam, the prescribed values in this Directive are met at HV (with a tolerance of 0,2 lux) and related to that aiming at least one point of each area delimited on the measuring screen (at 25 m) by a circle 15 cm in radius around points B 50 L (or R) (with a tolerance of 0,1 lux), 75 R (or L), 50 R (or L), 25 R, 25 L and in the entire area of zone IV which is not more than 22,5 cm above line 25 R and 25 L.5.2.1. If, for the driving beam, HV being situated within the isolux 0,75 Emax, a tolerance of + 20 % for maximum values and - 20 % for minimum values is observed for the photometric values at any measuring point specified in section 3.2.5 of this Annex, the reference mark is disregarded.5.3. If the results of the tests described above do not meet the requirements, the alignment of the headlamp may be changed, provided that the axis of the beam is not displaced laterally by more than 1° to the right or left.5.4. Headlamps with apparent defects are disregarded.5.5.

ADDITIONAL REQUIREMENTS CONCERNING MARKS AND THE MARKING OF DEVICES1.1. Headlamps designed in such a way as to meet the requirement of a single rule of the road (driving on either the right or the left) must, on the lens, bear the limits of the area which may possibly be masked in order to avoid distracting road users in a country where the rule of the road is not that for which the headlamp has been designed. However, when that area is directly identifiable by design any such delimitation is not necessary.1.2. Headlamps designed in such a way as to meet the requirements of driving on the right and those for driving on the left must bear markings in order to locate the two positions for the fixing in position of the light unit on the vehicle or the lamp on the reflector; these markings consist of the letters 'R/D` for the position corresponding to driving on the right and the letters 'L/G` for the position corresponding to driving on the left.1.3. All headlamps designed in such a way as to preclude any simultaneous lighting-up of the dipped-beam filament and that of any other light source with which they may be associated must be marked with an oblique stroke (/) within the component type-approval mark, after the passing beam-headlamp symbol.1.4. Where headlamps meet only the requirements of driving on the left, a horizontal arrow pointing to the right of an observer looking at the headlamp head-on, i.e. towards the side of the road driven upon, must be entered below the component type-approval mark.1.5. Where by means of a deliberate alteration in the adjustment of the light unit or lamp, headlamps meet the requirements of both rules of the road, a horizontal arrow having two tips pointing one to the left and the other to the right must be entered below the component type approval mark.1.6. The following additional symbol or symbols:1.6.1. on headlamps meeting left-hand traffic requirements only, a horizontal arrow pointing to the right of an observer facing the headlamp, i.e. to the side of the road on which traffic moves;1.6.2. on headlamps designed to meet the requirements of both traffic systems by means of an appropriate adjustment of the setting of the optical unit or the filament lamp, a horizontal arrow with a head at each end, the heads pointing respectively to the left and to the right;1.6.3. on headlamps meeting the requirements of this Directive in respect of the passing beam only, the letters 'HC`;1.6.4. on headlamps meeting the requirements of this Directive in respect of the driving beam only, the letters 'HR`;1.6.5. on headlamps meeting the requirements of this Directive in respect of both the passing and the driving beam, the letters 'HCR`;1.6.6. on headlamps incorporating a lens of plastic material, the letters 'PL` to be affixed near the symbols prescribed in 1.6.3 to 1.6.5.2. GENERAL SPECIFICATIONS2.1. Each sample must conform to the specifications set out in sections 6 to 8.2.2. Headlamps must be so made as to retain their prescribed photometric characteristics and to remain in good working order when in normal use, in spite of the vibrations to which they may be subjected.2.2.1. Headlamps must be fitted with a device enabling them to be so adjusted on the vehicle in such a way as to comply with the rules applicable to them. Such a device need not be fitted on components in which the reflector and the lens cannot be separated provided the use of such components is confined to vehicles on which the headlamp setting can be adjusted by other means. Where a headlamp providing a driving beam and a headlamp providing a passing beam, each equipped with its own filament lamp, are assembled to form a composite unit, the adjusting device must enable each optical system individually to be duly adjusted. However, this does not apply to headlamp assemblies whose reflectors are indivisible. For this type of assembly, the requirements of section 6 apply.2.3. The components by which the filaments lamp(s) is/are fixed to the reflector must be made in such a way that, even in darkness, the filament lamp(s) can be fixed in no other position but the correct one (1) (2).The filament lamp-holder must conform to the dimensional characteristics as given in the following data sheets of CIE Publication 61-2:>TABLE>2.4. Headlamps designed to satisfy the requirements of both right-hand and left-hand traffic may be adapted for traffic on a given side of the road either by an appropriate initial setting when fitted on the vehicle or by selective setting by the user. Such initial or selective setting may consist, for example, of fixing either the optical unit at a given angle on the vehicle or the filament lamp at a given angle in relation to the optical unit. In all cases, only two precise setting positions, one for right-hand and one for left-hand traffic, must be possible, and the design must preclude inadvertent shifting of the headlamp from one position to the other or its setting in an intermediate position. Where two different setting positions are provided for the filament lamp, the components attaching the filament lamp to the reflector must be designed and made so that, in each of its two settings, the filament lamp is held in position with the precision required for headlamps intended for traffic on only one side of the road. Conformity with the requirements of this section must be verified visually and, where necessary, by a test fitting.2.5. Only for headlamps equipped with single-filament halogen lamps: On headlamps designed to provide alternately a driving beam and a passing beam, any mechanical, electro-mechanical or other device incorporated in the headlamp for switching from one beam to the other (3) must be so constructed that:2.5.1. the device is strong enough to be worked 50 000 times without suffering damage despite the vibration to which it may be subjected in normal use;2.5.2. in the case of failure it is possible to obtain the passing beam automatically;2.5.3. either the passing beam or the driving beam can always be obtained without any possibility of the mechanism stopping in between the two positions;2.5.4. the user cannot, with ordinary tools, change the shape or position of the moving parts.2.6. Complementary tests must be carried out in accordance with the requirements of Appendix 2 to ensure that in use there is no excessive change in photometric performance.2.7. If the lens of the headlamp is of plastic material, tests must be carried out in accordance with the requirements of Appendix 3.3. ILLUMINATION3.1. General provisions3.1.1. Headlamps must be made in such a way that, with suitable H1, H2, H3, HB3, HB4, H7 and/or H4 filament lamps, they provide adequate illumination without dazzle in the case of the passing beam and good illumination in the case of the driving beam.3.1.2. The illumination produced by the headlamp must be checked on a vertical screen set at a distance of 25 m in front of the headlamp and at right angles to its axis (see Appendix 1).3.1.3. The headlamps must be checked by means of (a) standard (reference) filament lamp(s) designed for a rated voltage of 12 V. During the checking of the headlamp, the voltage at the terminals of the filament lamp must be regulated so as to obtain the following characteristics:>TABLE>The headlamp is deemed satisfactory if the photometric requirements are met with at least one standard (reference) 12-volt filament lamp which may be supplied with the headlamp.3.1.4. The dimensions determining the position of the filament inside the standard (reference) 12-volt filament lamp are shown on the relevant data sheet of Annex 4.3.1.5. The bulb of the standard (reference) filament lamp must be of such optical shape and quality that it does not cause any reflection or refraction adversely affecting the light distribution. Compliance with this requirement must be checked by measuring the light distribution obtained when a standard headlamp is fitted with the standard (reference) filament lamp.3.2. Provisions regarding passing beams3.2.1. The passing beam must produce a sufficiently sharp cut-off to permit satisfactory adjustment with its aid. The cut-off must be horizontal straight line on the side opposite to the direction of traffic for which the headlamps is intended; on the other side it must extend neither beyond the broken line H-V, H1-H4 formed by a straight line HV-H1 standing at an angle of 45° to the horizontal and a straight line H1-H4 lying 25 cm above the straight line hh, nor beyond the straight line HV-H3, inclined at an angle of 15° above the horizontal (see Appendix 1). A cut-off extending beyond both line HV-H2 and H2-H4 and resulting from a combination of the above two possibilities shall in no circumstances be permitted.3.2.2. The headlamp must aimed in such a way that:3.2.2.1. in the case of headlamps designed to meet the requirements of right-hand traffic, the cut-off on the left half of the screen (4) is horizontal and in the case of headlamps designed to meet the requirements of left-hand traffic, the cut-off on the right half of the screen is horizontal.3.2.2.2. this horizontal part of the cut-off is situated 25 cm below the line h-h (see Appendix 1);3.2.2.3. the elbow of the cut-off is on line v-v (5).3.2.3. when so aimed the headlamp need, if its approval is sought solely for a passing beam (6), comply only with the requirements referred to in 3.2.5 to 3.2.7 and 3.3.3.2.4. Where a headlamp so aimed does not meet the requirements of 3.2.5 to 3.2.7 and 3.3, its alignment may be changed provided that the axis of the beam is not laterally displaced by more than 1° (= 44 cm) to the right or left (7). To facilitate adjustment by means of the cut-off, the headlamp may be partially occluded in order to sharpen the cut-off.3.2.5. The illumination produced on the screen by the passing beam must meet the following requirements:>TABLE>3.2.6. There must be no lateral variations detrimental to good visibility in any of the zones I, II, III and IV.3.2.7. The illumination values in zones 'A` and 'B` as shown in figure C in Annex IV must be checked by the measurement of the photometric values of points 1 to 8 on this figure; these values must lie within the following limits:- 0,7 lux &ge; 1, 2, 3, 7 &ge; 0,1 lux- 0,7 lux &ge; 4, 5, 6, 8 &ge; 0,2 lux3.2.8. Headlamps designed to meet the requirements of both right-hand and left-hand traffic must in each of the two setting positions of the optical unit or of the filament lamp, meet the requirements set out above for the corresponding direction of traffic.3.3. Provisions regarding driving beams3.3.1. In the case of a headlamp designed to provide a driving beam and a passing beam, measurements of the illumination produced on the screen by the driving beam must be taken with the same headlamp alignment as for measurements under 3.2.5 to 3.2.7. In the case of a headlamp providing a driving beam only, it must be adjusted that the area of maximum illumination is centred on the point of intersection of the lines h-h and v-v. Such a headlamp need meet only the requirements referred to in 3.3.3.3.2. The illumination produced on the screen by the driving beam must meet the following requirements:3.3.2.1. the point of intersection (HV) of lines h-h and v-v must be situated within the isolux representing 90 % of maximum illumination. This maximum value (Emax) must be not less than 48 lux. The maximum value must in no case exceed 240 lux. Moreover, in the case of a combined passing and driving headlamp, this maximum value must not be more than 16 times the illumination measured for the passing beam at point 75 R (or 75 L).3.3.2.1.1. the maximum luminous intensity (lmax) of the driving beam expressed in thousands of candelas must be calculated by means of the formula:lmax = 0,625 Emax3.3.2.1.2. the reference mark (l'max) indicating this maximum intensity and referred to in 1.6 must be obtained by means of the formula:l'max =  >NUM>lmax >DEN>3 =  0,208 Emaxthis value being rounded to whichever is the nearest of the following: 7,5, 10, 12,5, 17,5, 20, 25, 27,5, 30, 37,5, 40, 45, 50.3.3.2.2. Starting from the HV point horizontally to the right and left, the illumination must not be less than 24 lux up to a distance of 1,125 m and not less than 6 lux up to a distance of 2,25 m.3.4. The screen illumination values referred to in 3.2.5 to 3.2.7 and 3.3 must be measured by means of a photoreceptor, the effective area of which must be contained within a square of 65 mm side.4. GAUGING DISCOMFORTThe discomfort caused by the passing beam of headlamps must be gauged.5. STANDARD HEADLAMP5.1. A headlamp is deemed to be a standard (reference) headlamp if it:5.1.1. satisfies the abovementioned requirements for approval;5.1.2. has an effective diameter of not less than 160 mm;5.1.3. provides with a standard filament lamp, at the various points and in the various zones referred to in 3.2.5, illumination equal to:5.1.3.1. not more than 90 % of the maximum limits and5.1.3.2. not less than 120 % of the minimum limits prescribed in the table in 3.2.5.6. ADDITIONAL REQUIREMENTS ATTACHED TO ANY INSPECTIONS WHICH MAY BE CARRIED OUT BY THE COMPETENT AUTHORITIES WHEN CHECKING CONFORMITY OF PRODUCTION IN ACCORDANCE WITH SECTION 5.1 OF ANNEX I6.1. For values B 50 L (or R) and Zone III the maximum deviation may be respectively>TABLE>6.2. For the passing beam, the prescribed values in this Directive are met at HV (with a tolerance of 0,2 lux) and related to that aiming at least one point of each area delimited on the measuring screen (at 25 m) by a circle 15 cm in radius around point B 50 L (or R) (with a tolerance of 0,1 lux), 75 R (or L), 50 R (or L), 25 R, 25 L and in the entire area of zone IV which is not more than 22,5 cm above line 25 R and 25 L.6.2.1. If, for the driving beam, HV being situated within the isolux 0,75 Emax, a tolerance of + 20 % for maximum values and - 20 % for minimum values is observed for the photometric values at any measuring point specified in section 3.2.5 of this Annex, the reference mark is disregarded.6.3. If the results of the tests described above do not meet the requirements, the alignment of the headlamp may be changed, provided that the axis of the beam is not displaced laterally by more than 1° to the right or left.6.4. Headlamps with apparent defects are disregarded.6.5. The reference mark is disregarded.Appendix 1 Measuring screen Standard European beamA. Headlamp for right-hand traffic>REFERENCE TO A GRAPHIC>B.

'Complete headlamp` is understood to mean the complete lamp itself including those surrounding body parts and lamps which could influence its thermal dissipation.1. TEST OF STABILITY OF PHOTOMETRIC PERFORMANCEThe tests are carried out in a dry and still atmosphere at an ambient temperature of 23 °C ± 5 °C, the complete headlamp being mounted on a base representing the correct installation on the vehicle.1.1. Clean headlampThe headlamp is operated for 12 hours as described in 1.1.1 and checked as prescribed in 1.1.2.1.1.1. Test procedureThe headlamp is operated for a period according to the specified time, so that:1.1.1.1. (a) in the case where only one lighting function (driving or passing beam) is to be approved, the corresponding filament is for the prescribed time (8),(b) in the case of a reciprocally incorporated passing lamp and driving lamp (dual-filament lamp or two filament lamps):- If the applicant declares that the headlamp is to be used with a single filament lit (9), the test is carried out in accordance with this condition activating (10) each specified function successfully for half the time specified in 1.1,- in all other cases (11) (12), the headlamp is subjected to the following cycle until the time specified is reached:- 15 minutes, passing beam filament lit- 5 minutes, all filaments lit,(c) in the case of grouped lighting functions all the individual functions must be lit simultaneously for the time specified for individual lighting functions (a) also taking into account the use of reciprocally incorporated lighting functions (b), according to the manufacturer's specifications.1.1.1.2. Test voltageThe voltage must be adjusted so as to supply 90 % of the maximum wattage specified in Annex IV. The applied wattage must in all cases comply with the corresponding value of a filament lamp of 12 V rated voltage, except if the applicant for approval specifies that the headlamp may be used at a different voltage. In the latter case, the test is carried out with the filament lamp whose wattage is the highest that can be used.1.1.2. Test results1.1.2.1. Visual inspectionOnce the headlamp has been stabilized to the ambient temperature, the headlamp lens and the external lens, if any, must be cleaned with a clean, damp cloth. It must then be inspected visually; no distortion, deformation, cracking or change in colour of either the headlamps or the external lens, if any, must be noticeable.1.1.2.2. Photometric testTo comply with the requirements of this directive, the photometric values must be verified in the following points:Passing beam:- 50 R - B 50 L - HV for headlamps designed for right-hand traffic,- 50 L - B 50 R - HV for headlamps designed for left-hand traffic.Driving beam:- Point of Emax.Another adjustment may be carried out to allow for any deformation of the headlamp base due to heat (the change of the position of the cut-off line is covered in section 2 of this Appendix).A 10 % discrepancy between the photometric characteristics and the values measured prior to the test is permissible, including the tolerances of the photometric procedure.1.2. Dirty headlamp,After being tested as specified in 1.1, the headlamp must be operated for one hour as described in 1.1.1, after being prepared as prescribed in 1.2.1, and checked as prescribed in 1.1.2.1.2.1. Preparation of the headlamp1.2.1.1. Test mixtureThe mixture of water and polluting agent to be applied to the headlamp must be composed of nine parts (by mass) of silica sand with a grain size distributed between 0 and 100 ìm, one part (by mass) of vegetal carbon dust of a grain size distributed between 0 and 100 ìm, 0,2 (by mass) of NaCMC (13) and an appropriate quantity of distilled water, the conductivity of which is lower than 1 mS/m for the purpose of this test.The mixture must not be more than 14 days old.1.2.1.2. Application of the test mixture to the headlampThe test mixture must be uniformly applied to the entire light-emitting surface of the headlamp and then left to dry. This procedure is repeated until the illuminating value has dropped to 15 - 20 % of the values measured for each following point under the conditions described in paragraph 1 above:- Emax in driving beam for a driving/passing lamp,- Emax in driving beam for a driving lamp only.- 50 R and 50 V (14) for a passing lamp only, designed for right-hand traffic.- 50 L and 50 V for a passing lamp only, designed for left-hand traffic.1.2.1.3. Measuring equipmentThe measuring equipment must be equivalent to that used during headlamp approval tests. A standard (reference) filament lamp is used for the photometric verification.2. TEST FOR CHANGE IN VERTICAL POSITION OF THE CUT-OFF LINE UNDER THE INFLUENCE OF HEATThis test consists of verifying that the vertical drift of the cut-off line under the influence of heat does not exceed a specified value for an operating passing lamp.The headlamp tested in accordance with section 1 must be subjected to the test described in 2.1 without being removed from or readjusted in relation to its test fixture.2.1. TestThe test must be carried out in a dry and still atmosphere at an ambient temperature of 23 °C ± 5 °C.Using a series-production filament lamp which has been aged for at least one hour the headlamp is operated on passing beam without being removed from or readjusted in relation to its test fixture. (For the purpose of this test, the voltage must be adjusted as specified in 1.1.1.2.) The position of the cut-off line in its horizontal part (between VV and the vertical line passing through point B 50 R for left-hand traffic or B 50 L for right-hand traffic) must be verified 3 minutes (r3) and 60 minutes (r60) after operation.The measurement of the variation in the cut-off line position as described above is carried out by any method giving acceptable accuracy and reproducible results.2.2. Test resultsThe result expressed in milliradians (mrad) is considered as acceptable when the absolute value Är1 = | r3 - r60 | recorded on the headlamp is not more than 1,0 mrad (Är1 &le; 1,0 mrad).2.2.1. However, if this value is more than 1,0 mrad but not more than 1,5 mrad (1,0 mrad NUM>Är1 + Är11 >DEN>2 & le; 1,0 mradAppendix 3 Requirements for lamps incorporating lenses of plastic material and testing of lens or material samples and of complete lamps1.

TEST-PIECESBefore the test, the sample roll of adhesive tape must be conditioned for 24 hours in the specified atmosphere (see section 3 above).Five test-pieces each 400 mm long are tested from each roll. These test-pieces are taken from the roll after the first three turns have been discarded.5. PROCEDUREThe test must be carried out under the ambient conditions specified in section 3.The five test pieces are taken while the tape is radially unrolled at a speed of approximately 300 mm/s, and the test-pieces are then applied within 15 seconds in the following manner:- The tape is applied to the glass plate progressively with a slight lengthwise rubbing movement of the finger, without excessive pressure, in such a manner as to leave no air bubble between the tape and the glass plate.- The assembly is left in the specified atmospheric conditions for 10 minutes.- About 25 mm of the test-piece is unstuck from the plate in a plane perpendicular to the axis of the test-piece.- The plate is fixed and the free end of the tape folded back at 90°. Force is applied in such a manner that the separation line between the tape and the plate is perpendicular to this force and perpendicular to the plate.- The tape is then pulled to unstick at a speed of 300 mm/s and the force required is recorded.6. RESULTSThe five values obtained are arranged in order and the median value taken as the results of the measurement. This value is expressed in Newtons per centimetre of width of the tape.Appendix 4 Information document in respect of a type of headlamp equipped with halogen filament lamps, emitting an asymmetrical passing beam and a driving beam and intended to be fitted to motorcycles and tricycles>START OF GRAPHIC>(To be attached to the component type-approval application where this is submitted separately from the vehicle type-approval application)Order No (assigned by the applicant): ..........The component type-approval application in respect of a type of headlamp intended for two or three-wheel motor vehicles must contain the following information:- in Part A, in sections: 8.1 to 8.41.

The latter is limited only by the requirements laid down in section 3.3; however, the horizontal part of the cut-off should not extend beyond the line h-h (the provisions of section 3.3 are not applicable to headlamps intended to meet the requirements of this Annex for passing beam only).(8) When the tested headlamp is grouped and/or reciprocally incorporated with signalling lamps, the latter must be lit for the duration of the test. In the case of a direction indicator lamp, it must be lit in flashing operation mode with an on/off time ratio of approximately one to one.(9) If two or more lamp filaments are simultaneously lit when headlamp flashing is used, this is not considered as being normal use of the filament simultaneously.(10) NaCMC represents the sodium salt of carboxymethylcellulose, customarily referred to as CMC. The NaCMC used in the dirt mixture must have a degree of substitution (DS) of 0,6-0,7 and a viscosity of 200-300 cP for a 2 % solution 20 °C.(11) 50 V is situated 375 mm below HV on the vertical line v-v on the screen at 25 m distance.(12) For L2 the use of a focal distance of about 80 mm is recommended.ANNEX IV INCANDESCENT LAMPS INTENDED FOR USE IN COMPONENT TYPE-APPROVED LAMPS FOR MOPEDS, MOTORCYCLES AND TRICYCLES >TABLE>1.

METHOD OF DETERMINING THE EXTENT OF PROJECTION OF A COMPONENT MOUNTED ON THE OUTER SURFACE1.1. The extent of projection of a component mounted on a convex panel may be determined either directly or by reference to a sketch of an appropriate section of that component in its fitted position.1.2. If the extent of the projection of a component mounted on a panel other than convex cannot be determined by means of a simple measurement, it must be determined via the maximum variation in the distance between the centre of a 100 mm diameter sphere and the nominal line of the panel when the sphere is moved, while remaining constantly in contact with that component. An example of the use of this method is given in Figure 1.1.3. The extent of projection of, in particular, grab handles shall be measured in relation to a plane passing through the attachment points for those handles. Figure 2 shows an example.2. METHOD OF DETERMINING THE EXTENT OF PROJECTION OF HEADLAMP PEAKS AND SURROUNDS2.1. The projection beyond the outer surface of the headlamp shall be measured horizontally from the point of tangency of a 100 mm-diameter sphere as shown in Figure 3.3. METHOD OF DETERMINING THE SIZE OF A GAP BETWEEN GRILL COMPONENTS3.1. The size of any gap between grill components shall be determined via the distance between two planes passing through the points of tangency of the sphere and at right angles to the line joining those same points of tangency. Figures 4 and 5 give examples of the use of that method.Figure 1 >REFERENCE TO A GRAPHIC>Figure 2 >REFERENCE TO A GRAPHIC>Figure 3 >REFERENCE TO A GRAPHIC>Figure 4 >REFERENCE TO A GRAPHIC>Figure 5 >REFERENCE TO A GRAPHIC>(1) OJ No L 266, 2. 10. 1974, p. 4.ANNEX III Appendix 1 Information document in respect of external projections from a type of two or three-wheel motor vehicle >START OF GRAPHIC>(To be attached to the application for component type-approval where this is submitted independently of the application for vehicle type-approval)Serial No (assigned by the applicant): ..........The application for component type-approval in respect of external projections from a type of two or three-wheel motor vehicle shall contain the information set out in Annex II to Council Directive 92/61/EEC, in Section A, points:0.1,0.2,0.4 to 0.6,1.1,1.2.In the instance provided for by item 3.5 in Annex I to this Chapter, please describe, where appropriate, the measures taken in order to ensure safety.>END OF GRAPHIC>Appendix 2 Certificate of component type-approval in respect of external projections from a type of two or three-wheel motor vehicle >START OF GRAPHIC>Name of AdministrationMODELReport No ..........by testing body ..........Date: ..........Component type-approval No: ..........Extension No: ..........1.

'Radius of curvature of the constituent part of the rear view mirror` means the radius c of the arc of the circle which most closely approximates the rounded form of the part under consideration.11. 'Type of vehicle in respect of rear view mirrors` means motor vehicles do not differ among themselves in respect of the following essential aspects:11.1. The vehicle characteristics which may reduce the field of view and affect the fitting of rear view mirrors;11.2. The positions and types of mandatory and optional rear view mirror where the latter is fitted.12. 'Driver's ocular points` means two points 65 mm apart located 635 mm vertically above the R point relating to the driving position defined in the appendix to this Annex. The straight line joining these is at right angles to the vertical median longitudinal plane of the vehicle.The centre of the segment having as its extremities the two ocular points is located within a vertical longitudinal plane which must pass through the centre of the driver's seating position as specified by the manufacturer.13. 'Ambinocular vision` means the entire field of vision obtained by superimposing the monocular fields for the right and left eyes (see figure below).>REFERENCE TO A GRAPHIC>>TABLE>Appendix Procedure for the determination of the radius of curvature 'r` of the reflecting surface of the rear view mirror1. MEASUREMENTS1.1. ApparatusThe piece of apparatus known as a 'spherometer` described in Figure 1 shall be used.1.2. Measuring points1.2.1. The main radii of curvature are measured at three points as close as possible to one-third, one-half and two-thirds of the length of the major arc of the reflecting surface passing through the centre of that surface, in a vertical plane, or of the major arc passing through the centre of that surface, in a horizontal plane, if the latter part is the longer.1.2.2. However, if the dimensions of the reflecting surface make it impossible to obtain the measurements defined in Item 7, the inspecting bodies responsible for the tests may proceed with measurements at this point in two perpendicular directions which are as close as possible to those required above.2. CALCULATION OF RADIUS OF CURVATURE 'r`'r`, expressed in millimetres, is calculated via the formula:r =  >NUM>rp1 + rp2 + rp3 >DEN>3whererp1 = radius of curvature of the first measuring point,rp2 = radius of curvature of the second measuring point,rp3 = radius of curvature of the third measuring point.Figure 1 >REFERENCE TO A GRAPHIC>ANNEX II STRUCTURAL AND TESTING REQUIREMENTS APPLYING TO THE COMPONENT TYPE-APPROVAL OF REAR-VIEW MIRRORS 1.

The reflecting surface shall retain the characteristics required by Item 3.3 even after prolonged exposure to bad weather under normal conditions of use.4. TESTS4.1. Rear view mirrors shall be subjected to the tests described in Items 4.2 and 4.3.4.1.1. The test provided for in Item 4.2 is not required for all outside mirrors no part of which is less than 2 m from the ground whatever the setting selected, the vehicle being laden up to its technically permissible all-up weight.The above exception also applies where rear view mirror attachments (attachment plates, stems, ball-joints, etc.) are at least 2 m above the ground and within the overall width of the vehicle. That width shall be measured in the transverse vertical plane passing through the lower-most mirror attachments or through any other point ahead of that plane when this latter configuration gives a greater overall width.In this case, a description shall be supplied which states precisely that the rear view mirror is to be fitted in such a way that its attachment point shall be located on the vehicle as described above.When this exemption applies, the stem shall be marked indelibly with the symbol >START OF GRAPHIC> Ä2 m>END OF GRAPHIC>, which must also be referred to on the component type-approval certificate.4.2. Impact-behaviour test4.2.1. Description of test device4.2.1.1. The test device shall comprise a pendulum which is able to swing about 2 horizontal axes at right angles to each other and one of which is at right angles to the plane containing the release trajectory of the pendulum.The end of the pendulum shall comprise a hammer consisting of a rigid sphere having a diameter of 165 ± 1 mm, covered by 5 mm of rubber having a Shore A-hardness of 50.Provision is made for a device enabling the maximum angle adopted by the stem to be determined in the release plane.A support rigidly attached to the body of the pendulum mounts the samples under the impact conditions set out in Item 4.2.2.6.Figure 1 below sets out the dimensions for the test rig and its specific design features.Figure 1 >REFERENCE TO A GRAPHIC>4.2.1.2. The impact centre of the pendulum is identical with the centre of the sphere acting as the hammer. Its distance 'l` from the swing axis in the release plane is 1 metre ± 5 millimetres. The reduced mass of the pendulum is m° = 6,8 ± 0,05 kilogrammes ('m°` is linked to the total mass 'm` of the pendulum and distance 'd` between the centre of gravity of the pendulum and its axis of rotation via relationm° = m  >NUM>d >DEN>l).4.2.2. Description of test4.2.2.1. The rear view mirror is attached to its base by means of the procedure recognized by the manufacturer of the device or, where appropriate, by the builder of the vehicle.4.2.2.2. Directional positioning of the rear view mirror for the test.4.2.2.2.1. The mirror is aligned on the testing device on the pendulum in such a way that the axes which are horizontal and vertical when the mirror is fitted to a vehicle in accordance with the applicants' instructions are perceptibly in the same position.4.2.2.2.2. When a mirror is adjustable against its base, the test shall be carried out in the least acceptable fold-back position within the setting limits provided for by the applicant.4.2.2.2.3. Where the rear view mirror can be moved closer to or away from its base, the relevant device shall be placed in the position in which the distance between the housing and base is shortest.4.2.2.2.4. Where the reflecting surface can be moved within the housing, its setting shall be such that the upper edge furthest from the vehicle shall be in the most protruding position in relation to the housing.4.2.2.3. With the exception of test No 2 for inside rear view mirrors (see item 4.2.2.6.1), the pendulum is in the vertical position while the horizontal and vertical longitudinal planes passing through the centre of the hammer must pass through the centre of the reflecting surface as defined in Annex 1, Item 9. The longitudinal direction of swing of the pendulum must be parallel to the median longitudinal plane of the vehicle.4.2.2.4. When, under the setting conditions provided for in Items 4.2.2.1 and 4.2.2.2, the components of the rear view mirror restrict the return movement of the hammer, the point of impact must be realigned in a direction perpendicular to the axis of rotation or swivel under consideration.This shift must be that which is strictly necessary to the performance of the test. It must be limited in such a way that:- the sphere encompassing the hammer remains at least tangent to the cylinder defined in Item 1.4,- or hammer contact is at least 10 mm from the perimeter of the reflecting surface.4.2.2.5. The test consists of releasing the hammer form a height corresponding to a pendulum angle of 60 degrees to the vertical in such a way that the hammer strikes the rear view mirror when the pendulum reaches its vertical position.4.2.2.6. Mirrors shall be struck in the following different conditions:4.2.2.6.1. Inside mirrors (Class I)Test No 1: The point of impact shall be that defined in Item 4.2.2.3, the impact being such that the hammer strikes the rear view mirror on the reflecting-surface side.Test No 2: On the edge of the protective housing in such a way that the resultant impact is at 45 degrees to the plane of the reflecting surface and is within the horizontal plane passing through the centre of that surface. The impact is directed to the reflecting-surface side.4.2.2.6.2. Outside mirrors (Class L)Test No 1: The point of impact is that defined in Item 4.2.2.3 or 4.2.2.2, the impact being such that the hammer strikes the rear view mirror on its reflecting-surface side.Test No 2: The point of impact shall be that defined in Item 4.2.2.3 or 4.2.2.4, the impact being such that the hammer strikes the rear view mirror on the side opposite to its reflecting surface.4.3. Bending test on the protective housing attached to the stem4.3.1. Description of testThe protective housing is placed horizontally in a device in such a way that it is possible to lock the attachment support adjusters firmly. In the direction of the largest dimension of the housing, the end closest to the point of attachment on the adjuster for the support shall be immobilized by a 15 mm-wide rigid stop covering the entire width of the housing.At the other end, a stop identical to the one described above is placed on the housing so that the specified test load can be applied to it (Figure 2).The end of the housing opposite to that where the force is exerted may be locked rather than held in position as shown in Figure 2.Figure 2 Example of rear view mirror bending-test rig >REFERENCE TO A GRAPHIC>4.3.2. The test loading shall be 25 kilogrammes and shall be maintained for one minute.5. TEST RESULTS5.1. In the tests provided for in Item 4.2 the pendulum shall continue to swing in such a way that the projection on the release plane and the position adopted by the stem form an angle of at least 20 degrees with the vertical.The angle shall be measured to an accuracy of ± 1 degree.5.1.1. This requirement shall not apply to rear view mirrors stuck to windscreens. In this case the requirements set out in Item 5.2 shall apply after the test.5.2. During the test provided for in Item 4.2, the remaining part of rear view mirrors glued to windscreens after breakage of the support shall not protrude beyond the base by more than 1 cm and its configuration following the test shall meet the conditions set out in Item 1.3.5.3. During the tests provided for in Items 4.2 and 4.3, the reflecting surface shall not shatter. However, shattering of the reflecting surface is acceptable if either of the following conditions is met:5.3.1. the fragments stick to the base of the housing or to a surface which is solidly linked with this; however, partial unsticking of the glass is permitted provided that this does not exceed 2,4 mm either side of the cracks. It is acceptable for small shards to detach themselves from the surface of the glass at the point of impact;5.3.2. the reflecting surface shall be made of safety glass.Appendix 1 Test method for determining reflectiveness1. DEFINITIONS1.1. Standardized CIE A (1): illuminant colorimetric illuminant representing a black body at T68 = 2855,6 Kelvin.1.2. Standardized CIE A (2): gaseous atmosphere tungsten filament lamp operating at a proximal colour temperature of T68 = 2855,6 Kelvin.1.3. CIE 1931 (3) reference colorimetric observer: radiation receiver the colorimetric characteristics of which correspond to trichromatic spectrum components >START OF GRAPHIC> x >END OF GRAPHIC> (ë), >START OF GRAPHIC>y>END OF GRAPHIC> (ë), >START OF GRAPHIC>z>END OF GRAPHIC> (ë) (see table).1.4. CIE trichromatic spectrum components: trichromatic components, within the CIE (XYZ) system of the monochromatic parts of a spectrum of equal energy.1.5. Photopic vision (4): normal-eye vision when adapted to luminance levels of at least several candelas per square meter.2. APPARATUS2.1. GeneralThe apparatus shall incorporate a light source, a support for the test piece, a photoelectric cell receiver and an indicator (see Figure 1), together with the necessary means of suppressing the effects of stray light.The receiver may include an Ulbricht sphere in order to make it easier to measure the coefficient of reflection of non-plane (i.e. convex) rear view mirrors (see Figure 2).2.2. Spectral characteristics of the light source and receiverThe light source shall be a standardized CIE A source associated with an optical system enabling a beam of almost parallel light rays to be obtained. It is recommended that a voltage stabilizer be provided for in order to maintain a fixed lamp voltage throughout the functioning of the apparatus.The receiver shall include a photoelectric cell the spectral response of which is proportional to the photopic luminosity function of the CIE (1931) reference colorimetric observer (see table). Any other illuminant-filter-receiver combination providing an overall equivalence to the standardized CIE A illuminant and photopic vision may also be adopted. If the receiver incorporates an Ulbricht sphere, the inner surface of the sphere shall be coated with matt (diffuse) white non-selective paint.2.3. Geometrical conditionsThe beam of incident rays must preferably form an angle (È) of 0,44 ± 0,09 radians (25 ± 5°) with the perpendicular to the test surface; this angle must, however, not exceed the upper limit of the tolerance i.e. 0,53 radians or 30°. The axis of the receiver must form an angle (È) equal to that of the beam of the incident rays with said perpendicular (see Figure 1). On its arrival at the test surface the incident beam must have a diameter of at least 19 mm. The reflected beam must not be wider than the sensitive surface of the photoelectric cell, must not cover less than 50 % of that surface and must, if possible, cover the same portion of the surface as the beam used to calibrate the instrument.If the receiver includes an Ulbricht sphere, this shall have a minimum diameter of 127 mm. The openings made for the testpiece and incident beam in the wall of the sphere must be of sufficient size to allow the incident and reflected light beams to pass through in their entirety. The photoelectric cell must be positioned in such a way as not directly to receive the light from the incident or reflected beams.2.4. Electrical characteristics of the combined cell and indicatorThe power of the photoelectric cell displayed on the indicator must be a linear function of the light intensity of the photosensitive surface. Provision must be made for (electrical or optical) means (or both) of easing, resetting and adjusting the calibration settings. These means must not affect the linearity or spectral characteristics of the instrument. These means must not affect the linearity or spectral characteristics of the instrument. The accuracy of the combined receiver and indicator shall be ± 2 % of the full scale or ± 10 % of the value measured in accordance with the smallest value.2.5. Testpiece supportIts mechanisms must enable the sample to be located in such a way that the axis of the source arm and that of the receiver arm meet at the level of the reflecting surface. That reflecting surface may be within the sample rear view mirror or its two sides, depending on whether this is a primary or secondary surface mirror or a prismatic mirror of the 'flip` type.3. METHOD OF PROCEDURE3.1. Direct calibration methodWhere the direct calibration method is used the reference shall be air. This method can be applied with instruments which have been so devised as to permit calibration at full scale by aligning the receiver directly with the axis of the lights (see Figure 1).In certain cases (in order, for example, to measure low-reflectiveness surfaces), this method enables an intermediate calibration point to be taken (between 0 and 100 % scale). In these instances it is necessary to interpose a neutral-density filter having a known transmission factor within the optical trajectory and to adjust the calibration system until the indicator shows the percentage transmission corresponding to the neutral-density filter. That filter must be removed before the reflectiveness measurements begin.3.2. Indirect calibration measurementsThis calibration method shall apply to instruments having a source and receiver with a fixed geometrical shape. It requires a suitably calibrated and maintained reflection standard. That standard will preferably be a plane rear view mirror the coefficient of reflection of which is as close as possible to that of the examples tested.3.3. Measurements on a plane rear view mirrorThe coefficient of reflection of plane-mirror test pieces may be measured using instruments employing the principle of direct or indirect calibration. The value of the coefficient of reflection is read directly from the instrument dial.3.4. Measurements on a non-plane (convex) rear view mirrorMeasurement of the coefficient of reflection of non-plane (convex) rear view mirrors requires the use of instruments incorporating an Ulbricht sphere within the receiver (see Figure 2). If with a standard mirror having a coefficient of reflection of E %, the sphere read out gives ne divisions with an unknown mirror, nx divisions will correspond to a coefficient of reflection of X %, as given by the following formula:X = E  >NUM>nx >DEN>ne.Figure 1: General layout drawing of the reflectivity measuring apparatus using the two calibration methods >REFERENCE TO A GRAPHIC>Figure 2: General layout drawing of the reflectivity measuring equipment using an Ulbricht sphere in the receiver >REFERENCE TO A GRAPHIC>Values for the spectral trichromatic components of the CIE 1931 (5) colorimetric reference observerThis table has been extracted from publication CIE 50 (45) - 1970>TABLE>Appendix 2 Component type-approval and marking of rear view mirrors1.

DEFINITIONSFor the purposes of this Chapter:1.1. 'Vehicle type with regard to the emission of gaseous pollutants from the engine` means mopeds which do not differ in such essential respects as the following:1.1.1. The equivalent inertia determined in relation to the reference mass, as laid down in section 5.2 of Appendix 1;1.1.2. The characteristics of the engine and the moped as defined in Annex V;1.2. 'Reference mass` means the mass of the moped in running order, increased by a uniform mass of 75 kg. The mass of the moped in running order is its total unladen mass with all tanks filled to at least 90 % of their maximum capacity;1.3. Gaseous pollutants'Gaseous pollutants` means carbon monoxide, hydrocarbons and oxides of nitrogen expressed in terms of nitrogen dioxide (NO2) equivalence.2. TEST SPECIFICATIONS2.1. GeneralThe components liable to affect the emission of gaseous pollutants must be designed, constructed and assembled so as to enable the moped, in normal use, despite the vibrations to which it may be subjected, to comply with the requirements of this Annex.2.2. Description of tests2.2.1. The moped must be subjected to Type I and II tests, as specified below:2.2.1.1. Type I test (checking the average emissions of gaseous pollutants in a congested urban area)2.2.1.1.1. The vehicle is placed on a dynamometer equipped with a brake and a flywheel. A test lasting a total of 448 seconds and comprising four cycles is carried out without interruption.Each cycle comprises seven operations (idling, acceleration, steady speed, deceleration, etc.). During the test the exhaust gases are diluted with air so that the flow volume of the mixture remains constant. Throughout the test:- a continuous flow of samples of the mixture must be passed into a bag so that the concentrations (average test values) of carbon monoxide, unburnt hydrocarbons and oxides of nitrogen can be determined in succession;- the total volume of the mixture is measured.At the end of the test the distance effectively travelled is recorded from the total shown on the additive revolution counter driven by the roller.2.2.1.1.2. The test is carried out by the procedure described in Appendix 1. The methods used to collect and analyse the gases are those laid down.2.2.1.1.3. Subject to the provisions 2.2.1.1.4, the test is carried out three times. The mass of the carbon monoxide, hydrocarbons and nitrogen oxides obtained in each test must be less than the limit values set out in the table below.>TABLE>2.2.1.1.3.1. However, one of the three results for each of the abovementioned pollutants may exceed the limit value prescribed for the moped concerned by a maximum of 10 %, provided that the arithmetic mean of the three results is less than the prescribed limit value. If more than one pollutant exceeds the prescribed limit values, it is immaterial whether this occurs in the same test or in different tests.2.2.1.1.4. The number of tests prescribed in 2.2.1.1.3 is reduced under the conditions described below, where V1 is the result of the first test and V2 is the result of the second test for each of the pollutants referred to in 2.2.1.1.3.2.2.1.1.4.1. Only one test is required if V1 &le; 0,70 L for all the pollutants concerned.2.2.1.1.4.2. Only two tests are required if V1 &le; 0,85 L for all the pollutants concerned and if, for at least one pollutant, V1 > 0,70 L. In addition, for each of the pollutants concerned, V2 must be such that V1 + V2 3. CONFORMITY OF PRODUCTION3.1. The provisions of paragraph 1 of Annex VI to Council Directive 92/61/EEC of 30 June 1992 on the type-approval of two or three-wheel motor vehicles apply to the checking of conformity of production.3.1.1. However, the following approach must be adopted when checking conformity with regard to the type I test:3.1.1.1. a vehicle is taken from the production line and subjected to the test described in 2.2.1.1. The limit values specified are taken from the table in 2.2.1.1.3.3.1.2. If the vehicle taken from the production line does not meet the requirements of 3.1.1, its manufacturer may request that measurements be taken from a sample of vehicles taken from the production line which includes the vehicle initially selected. Its manufacturer lays down the size n of the sample. The arithmetical mean >START OF GRAPHIC> x >END OF GRAPHIC> of the results obtained with the sample and the type S divergence of the sample are then determined for the emission of carbon monoxide and the total emissions of hydrocarbons and nitrogen oxides.Series production is considered to be in conformity if the following condition is met:>START OF GRAPHIC> x >END OF GRAPHIC> + k  7 S &le; L (1),where:L: is the limit value required by the table in 2.2.1.1.3, for the emission of carbon monoxide and for the total emissions of hydrocarbons and nitrogen oxides;k: is the statistical factor depending upon n and set out in the table below:>TABLE>Where n &ge; 20, k =  >NUM>0,860 >DEN>&radic;n4. EXTENSION OF THE SCOPE OF THE APPROVAL4.1. Vehicle types with different reference massesThe approval may be extended to vehicle types differing from the approved type only in their reference mass provided that the reference mass of the vehicle type for which extension of the approval is requested merely results in the application of the next higher or lower inertia mass equivalents.4.2. Vehicle types with different total gear ratios4.2.1. The approval for a vehicle type may be extended under the following conditions to such vehicle types that differ from the approved type only in their total gear ratios.4.2.1.1. For every gear used for the Type I tests,the relationshipE =  >NUM>V2 - V1 >DEN>V1has to be determined;where V1 and V2 are the speeds, corresponding to an engine speed of 1 000 rpm, of the approved vehicle type and of the vehicle type for which the extension is requested.4.2.2. If the relationship E &le; 8 % applies to every gear, the extension must be approved without repeating the Type I tests.4.2.3. Should the gear ratio be E > 8 % for at least one gear and E &le; 13 % for each gear, the Type I tests must be repeated; however, they may be carried out in a laboratory that the manufacturer may choose himself subject to the agreement of the component approval authority. The test report must be passed to the technical service.4.3. Vehicle types with different reference masses and different total gear ratiosThe approval for a vehicle type may be extended to cover vehicle types that differ from the approved type only in their reference mass and in their total gear ratios if they comply with the requirements of 4.1 and 4.2.4.4. Three-wheel mopeds and light quadricyclesThe approval granted to two-wheel mopeds may be extended to include three-wheel mopeds and light quadricycles if they use the same engine and the same exhaust system and have the same transmission which differs only in respect of the gear ratio, provided that the reference mass of the vehicle type for which extension of the approval is requested merely results in the application of the next higher or lower inertia mass equivalents.4.5. No further extension of approvals may be given to extensions granted in accordance with 4.1 to 4.4.Appendix 1 Type I test(checking the average emission of pollutants in a congested urban area)1. INTRODUCTIONProcedure for Type I test specified in section 2.2.1.1 of Annex I.2. OPERATING CYCLE ON THE DYNAMOMETER2.1. Description of cycleThe operating cycle on the dynamometer is as indicated in the following table and plotted in Sub-appendix 1.>TABLE>2.2. General conditions for carrying out the cyclePreliminary testing cycles must be carried out if necessary to determine how best to actuate the accelerator and, if necessary, the gears and brake.2.3. Use of the gearboxThe gearbox must be used in accordance with the manufacturer's instructions. If there are no manufacturer's instructions the following rules apply:2.3.1. Manual gearboxAt a steady speed of 20 km/h, the engine speed must as far as possible remain between 50 % and 90 % of the maximum speed. If this speed can be achieved using more than one gear, the moped is tested using the highest gear.During acceleration, the moped is tested using the gear which allows maximum acceleration. The next highest gear must be engaged at the latest when the engine speed has reached 110 % of rated maximum output. During deceleration, the next lowest gear must be engaged before the engine begins to vibrate and at the latest when the engine speed has fallen to 30 % of rated maximum output. First gear must not be engaged during deceleration.2.3.2. Automatic gearbox and torque converterThe 'drive` setting is used.2.4. Tolerances2.4.1. A tolerance of 1 km/h above or below the theoretical speed must be allowed during all phases.Speed tolerances greater than those prescribed are permitted during phase changes provided that the tolerances are not exceeded for more than 0,5 s on any one occasion.If the moped decelerates more rapidly than expected without use of the brakes, the procedure specified in 6.2.6.3 applies.2.4.2. Tolerances of 0,5 s above or below the theoretical times are allowed.2.4.3. The speed and time tolerances must be combined as shown in Sub-appendix 1.3. MOPED AND FUEL3.1. Test moped3.1.1. The moped must be presented in good mechanical condition. It must have been run in and driven at least 250 km before the test.3.1.2. The exhaust device must not have any leaks likely to reduce the quantity of gases collected, which must equal the quantity of gases emerging from the engine.3.1.3. The leak-tightness of the induction system may be checked to ensure that carburation is not affected by an accidental intake of air.3.1.4. The engine settings and the moped's controls must be those prescribed by the manufacturer. This also applies, in particular, to the idling speed adjustment (rotating speed and carbon monoxide content of exhaust gases), to the automatic choke and to the exhaust gas clean-up system.3.1.5. The laboratory may verify that the moped delivers the performance specified by its manufacturer, that it can be used for normal driving, and more particularly that it is capable of starting when cold and when hot and can idle without stalling.3.2. FuelThe fuel used for the test must be the reference fuel, the specifications for which are set out in Annex IV. If the engine is lubricated by a mixture, the oil added to the reference fuel must comply as to quality and quantity with the manufacturer's recommendations.4. TEST EQUIPMENT4.1. DynamometerThe main characteristics of the dynamometer are as follows:- load curve equation: on the dynamometer it must be possible, from the initial speed of 12 km/h, to reproduce, with a tolerance of ± 15 %, the power developed by the engine when the moped is travelling along a flat road with a wind speed of virtually zero.Otherwise the power absorbed by the brakes and the internal friction of the bench (PA) must be:at a speed 0  12 km/h:PA = kV³ ± 5 % kV³ ± 5 % PV50 (3)without being negative (the calibration method must comply with the provisions of Sub-appendix 4)- basic inertia: 100 kg- additional inertias (4): from 10 kg and 10 kg- the roller must have a revolution counter which can be reset to zero, so as to measure the distance actually travelled.4.2.

A device to suck in the diluted gases. This device must guarantee constant flow of a sufficient volume to ensure that all the exhaust gases are sucked in.4.2.4. A sampling probe attached to the outside of the gas-collection device which can collect a constant sample of the dilution air using a pump, a filter and a flow meter for the duration of the test.4.2.5. A sampling probe directed upstream of the flow of diluted gases to sample the mixture for the duration of the test at a constant rate of flow using, if necessary, a filter, a flow meter and a pump. The minimum rate of flow of the gases in the two sampling systems described above must be at least 150 l/h.4.2.6. Three-way valves on the sampling circuits described above to direct the flow of samples either to the atmosphere or to their respective sampling bags for the duration of the test.4.2.7. Leak-tight sampling bags to collect the dilution air and mixture of diluted gases which are unaffected by the pollutants concerned and of sufficient capacity not to disrupt the normal flow of sampling. These sampling bags must have automatic sealing devices which can be closed rapidly and tightly, either on the sampling circuit or on the analysis circuit at the end of the test.4.2.8. There must be a method of measuring the total volume of diluted gases passing through the sampling device during the test.4.3. Analytical equipment4.3.1. The sampling probe may consist of a sampling tube leading into the collecting bags or of a bag-emptying tube. The probe must be of stainless steel or of a material which will not affect the composition of the gases. The sampling probe and the tube connecting it to the analyser must be at ambient temperature.4.3.2. Analysers must be of the following types:- the non-dispersive type with infra-red absorption for carbon monoxide;- the flame-ionization type for hydrocarbons- the chemiluminescent type for oxides of nitrogen.4.4. Accuracy of instruments and measurements4.4.1. As the brake is calibrated in a separate test (5.1), it is not necessary to indicate the accuracy of the dynamometer. The total inertia of the rotating masses, including that of the rollers and the rotating part of the brake (see 4.1), must be given to within ± 5 kg.4.4.2. The distance travelled by the moped is determined by the number of revolutions made by the roller to within an accuracy of ± 10 m.4.4.3. The speed of the moped is measured by the speed of rotation of the roller. It must be measurable to within ± 1 km/h for speeds above 10 km/h.4.4.4. Ambient temperature must be measurable to within ± 2 °C.4.4.5. The atmospheric pressure must be measurable to within ± 0,2 kPa.4.4.6. The relative humidity of the ambient air must be measurable to within ± 5 %.4.4.7. Irrespective of the accuracy with which the sampling gases are determined, the accuracy required when measuring the content of the various pollutants must be ± 3 %. The overall response time of the analysing circuit must be less than one minute.4.4.8.

The total volume of the diluted gases must be measurable to within ± 3 %.4.4.12. The total flow and sampling flow must be constant to within ± 5 %.5. PREPARING THE TEST5.1. Setting of brakeThe brake must be so adjusted that the speed of the moped on the bench at full throttle is equal to the maximum speed of which it is capable on the road, with a tolerance of ± 1 km/h. This maximum speed may not deviate by more than ± 2 km/h from the rated maximum speed as specified by the manufacturer. If the moped is fitted with a device to govern the maximum speed on the road, the effect of this governor must be taken into account.The brake may be adjusted using a different method if the manufacturer demonstrates its equivalence.5.2. Adjustment of equivalent inertias to the moped's translatory inertias.One or more flywheels are used enabling a total inertia of the rotating masses to be obtained that is proportional to the reference mass of the moped within the following limits:>TABLE>5.3. Cooling the moped5.3.1. For the duration of the test, an auxiliary forced-draught device is placed in front of the moped in such a way as to direct a flow of cooling air on to the engine. The air-flow speed is 25 ± 5 km/h. The blower's air outlet must be at least 0,2 m² in section, with its plane perpendicular to the longitudinal axis of the moped, and it must be placed between 30 and 45 cm ahead of the moped's front wheel. The device for measuring the linear speed of the forced draught must be placed in the middle of the jet of air 20 cm from the air outlet. As far as possible the air speed must be constant across the whole outlet section.5.3.2. The moped may also be cooled using the alternative method described below. A flow of air of variable speed is directed at the moped. The blower must be regulated in such a way that within the operating range, between 10 and 45 km/h inclusive, the linear air speed at the blower outlet is equal to the equivalent roller speed to within ± 5 km/h. At equivalent roller speeds of less than 10 km/h, the forced-draught air speed may be zero. The blower outlet must be at least 0,2 m² in section and its lower edge between 15 and 20 cm above ground level. The plane of the outlet must be perpendicular to the longitudinal axis of the moped and must be located between 30 and 45 cm in front of the moped's front wheel.5.4. Conditioning of the moped5.4.1. Immediately before starting the first test cycle, the moped must undergo four consecutive test cycles, each lasting 112 seconds, in order to warm up the engine.5.4.2. The tyre pressure must be that stated by the manufacturer for normal road use. However, if the diameter of the rollers is less than 500 mm, the pressure in the tyres may be increased by 30-50 %.5.4.3. Load on the driving wheel: the load on the driving wheel must be within ± 3 kg of the load, on a moped in normal road use, with a driver weighing 75 kg ± 5 kg, sitting in an upright position.5.5. Checking of back pressure5.5.1. During the preliminary tests a check must be made to ensure that the back pressure set up by the sampling device does not deviate from atmospheric pressure by more than ± 0,75 kPa.5.6. Calibration of analytical apparatus5.6.1. Calibration of analysersThe quantity of gas at the pressure stated to be compatible with the correct functioning of the equipment is injected into the analyser by means of the flow meter and discharge gauge mounted on each bottle. The apparatus must be adjusted to indicate as a stabilized value the value shown on the standard gas bottle. Starting from the setting obtained with the maximum-content bottle, the curve of the analyser's deviations is drawn as a function of the content of the various standard gas bottles used.5.6.2. Overall response time of the apparatus.The gas from the maximum-content bottle is injected into the end of the sampling probe. A check must be made to ensure that the indicated value corresponding to maximum deviation is attained in less than one minute. If this value is not attained, the analysing circuit must be inspected from end to end for leaks.6. PROCEDURE FOR DYNAMOMETER TESTS6.1. Special conditions for carrying out the cycle6.1.1. The temperature in the place where the dynamometer is situated must be between 20 and 30 °C throughout the test.6.1.2. The moped must as far as possible be horizontal during the test as to avoid any abnormal distribution of fuel or engine oil.6.1.3. During the test the speed is plotted against time so that the correctness of the cycles performed can be assessed.6.2. Starting up the engine6.2.1. Once the preliminary operations on the equipment for collecting, diluting, analysing and measuring the gases have been carried out (see 7.1), the engine is started up by means of the devices provided for that purpose, such as the choke, the starter valve, etc., according to the manufacturer's instructions.6.2.2. The taking of samples and the measuring of the flow through the suction device must commence at the beginning of the first cycle.6.2.3. Idling6.2.3.1. Manual-shift gearbox:To enable the accelerations to be performed according to the normal cycle the vehicle must be put in first gear, with the clutch disengaged, five seconds before commencement of the acceleration following the idling period in question.6.2.3.2. Automatic gearbox and torque converter:The selector is engaged at the beginning of the test. If there are two positions - 'town` and 'road` - the 'road` position must be used.6.2.4. AccelerationsAt the end of each idling period, acceleration must be effected by fully opening the throttle and if necessary using the gearbox in such a way as to reach the maximum speed as quickly as possible.6.2.5. Steady speedA steady maximum speed must be maintained by keeping the throttle fully open until the following deceleration phase. During the phase where the speed is kept at a steady 20 km/h, the throttle position must be kept as fixed as possible.6.2.6. Decelerations6.2.6.1. All decelerations are effected by completely closing the throttle, the clutch remaining engaged. The engine must be disengaged manually, without touching the gear level, at a speed of 10 km/h.6.2.6.2. If the period of deceleration is longer than that prescribed for the corresponding phase, the moped's brakes must be used to keep to the cycle.6.2.6.3. If the period of deceleration is shorter than that prescribed for the corresponding phase, the timing of the theoretical cycle is restored by an idling period merging into the following idling operation. In this case, section 2.4.3. is not applicable.6.2.6.4. At the end of the second deceleration period (stopping moped on the roller) the gear is put into neutral and the clutch engaged.7. PROCEDURE FOR SAMPLING AND ANALYSIS7.1. Sampling7.1.1. Sampling begins as soon as the test commences, as indicated in 6.2.2.7.1.2. The bags must be hermetically sealed as soon as they are full.7.1.3. At the end of the final cycle the device for collecting the diluted exhaust gases and the dilution air must be closed and the gases produced by the engine diverted into the atmosphere.7.2. Analysis7.2.1. The gases contained in each bag must be analysed as soon as possible and in any event not later than twenty minutes after filling of the bags commenced.7.2.2. If the sampling probe is not left permanently in the bags, the entry of air into the bags during insertion of the probe and the escape of gases from the bags during extraction of the probe must be avoided.7.2.3. The analyser must show a steady value within one minute after being connected up to the bag.7.2.4. The concentrations of HC, CO and NOx in the samples of diluted exhaust gases and in the bags collecting the dilution air are determined from the values shown or recorded by the measuring equipment by applying the correct calibration curves.7.2.5. The value adopted as the content of the gaseous pollutants in the gases analysed is that read off after stabilization of the measuring instrument.8.

PURPOSEThis Sub-appendix describes the method to be used for checking that the curve for the power absorbed by the dynamometer coincides with the absorption curve required under section 4.1 of Appendix 1.The measured absorbed power includes the power absorbed by friction and the power absorbed by the brake, but does not include the power dissipated by friction between the tyre and the roller.2. PRINCIPLE OF THE METHODThis method makes it possible to calculate absorbed power by measuring the roller deceleration time. The kinetic energy of the device is dissipated by the brake and by the friction of the dynamometer. This method does not take account of variations in internal roller friction due to the mass of the moped.3. PROCEDURE3.1. The inertia simulation system corresponding to the mass of the moped being tested is engaged.3.2. The brake is set in accordance with section 5.1. of Appendix 1.3.3. The roller is made to turn at velocity v + 10 km/h.3.4. The roller drive system is disconnected and the roller allowed to decelerate freely.3.5. The time taken by the roller to decelerate from velocity v + 0,1 v to velocity v - 0,1 v is noted.3.6. The absorbed power is calculated by means of the formula:PA = 0,2 ×  >NUM>Mv² >DEN>t × 10-3where:PA: is the power absorbed by the dynamometer expressed in kWM: is the equivalent inertia expressed in kgv: is the test velocity referred to in 3.3. expressed in m/st: is the time, expressed in seconds, taken by the roller to decelerate from v + 0,1 v to v - 0,1 v.3.7. The phases described in 3.3. to 3.6. are repeated to cover the range of speeds 10 to 50 km/h, by 10 km/h stages.3.8. The curve representing absorbed power as a function of speed is drawn.3.9. It must be ensured that the curve is within the tolerance specified in section 4.1 of Appendix 1.>REFERENCE TO A GRAPHIC>Appendix 2 Type II test(measuring emissions of carbon monoxide and hydrocarbons at idling speed)1.

INTRODUCTIONProcedure for Type I test specified in section 2.2.1.1 of Annex II.1.1. The motorcycle or motor tricycle is placed on a dynamometer equipped with a brake and flywheel. A test lasting a total of 13 minutes and comprising four cycles is carried out without interruption. Each cycle comprises 15 operations (idling, acceleration, steady speed, deceleration, etc.). During the test the exhaust gases are diluted with air so that the flow volume of the mixture remains constant. Throughout the test a continuous flow of samples of the mixture must be passed into a bag so that concentrations (average test values) of carbon monoxide, unburnt hydrocarbons, oxides of nitrogen and carbon dioxide can be determined in succession.2. OPERATING CYCLE ON THE DYNAMOMETER2.1. Description of cycleThe operating cycle on the dynamometer must be that indicated in the following table and plotted in Sub-appendix 1.2.2. General conditions for carrying out the cyclePreliminary test cycles must be carried out if necessary to determine how best to actuate the accelerator and brake controls so as to achieve a cycle approximating to the theoretical cycle within the prescribed limits.2.3. Use of the gearbox2.3.1. Use of the gearbox is determined as follows:2.3.1.1. At constant speed, the engine speed must as far as possible remain between 50 % and 90 % of the maximum speed. If this speed can be achieved using more than one gear, the engine is tested using the highest gear.2.3.1.2. During acceleration, the engine must be tested using the gear which allows maximum acceleration. The next higher gear is engaged at the latest when the engine speed has reached 110 % of rated maximum output. If a motorcycle or motor tricycle reaches a speed of 20 km/h in first gear or 35 km/h in second gear, the next higher gear must be engaged at these speeds.In these cases, no other change into higher gears is permitted. If, during the acceleration phase, the gears are changed at fixed motorcycle or motor tricycle speeds, the steady speed phase which follows must be performed with the gear which is engaged when the motorcycle or motor tricycle begins the steady speed phase, irrespective of the engine speed.2.3.1.3. During deceleration, the next lower gear must be engaged before the engine reaches virtual idling speed and at the latest when the engine speed has fallen to 30 % of rated maximum output, whichever occurs earlier. First gear must not be engaged during deceleration.2.3.2. Motorcycles or motor tricycles equipped with automatic gearboxes are tested with the highest gear engaged ('drive`). The accelerator must be operated in such a way as to obtain as steady an acceleration as possible so that the transmission engages the different gears in the normal order. The tolerances specified in 2.4 apply.2.4. Tolerances2.4.1. A tolerance of ± 1 km/h above or below the theoretical speed is allowed during all phases. Speed tolerances greater than those prescribed are permitted during phase changes provided that the tolerances are never exceeded for more than 0,5 on any one occasion, in all cases subject to the provisions of 6.5.2 and 6.6.3.2.4.2. A tolerance of ± 0,5 seconds above or below the theoretical times must be allowed.2.4.3. The speed and time tolerances are combined as indicated in Sub-appendix 1.2.4.4. The distance travelled during the cycle must be measured with a tolerance of ± 2 %.>TABLE>3. MOTORCYCLE OR MOTOR TRICYCLE AND FUEL3.1. Test motorcycle or motor tricycle3.1.1. The motorcycle or motor tricycle must be presented in good mechanical condition. It must have been run in and driven at least 1 000 km before the test. The laboratory may decide whether a motorcycle or motor tricycle which has travelled less than 1 000 km before the test may be accepted.3.1.2. The exhaust device must not have any leaks likely to reduce the quantity of gases collected, which must equal the quantity of gases emerging from the engine.3.1.3. The leak-tightness of the admission system may be checked to ensure that carburation is not affected by an accidental intake of air.3.1.4. The settings of the motorcycle or motor tricycle must be as prescribed by the manufacturer.3.1.5. The laboratory may verify that the motorcycle or motor tricycle delivers the performance stated by the manufacturer, that it can be used for normal driving, and more particularly that it is capable of starting when cold and when hot.3.2. FuelThe fuel used for the test must be the reference fuel as defined in Annex IV. If the engine is lubricated by a mixture, the oil added to the reference fuel must comply as to quality and quantity with the manufacturer's recommendations.4. TEST EQUIPMENT4.1. DynamometerThe main characteristics of the dynamometer are as follows:Contact between roller and tyre of each driving wheel:- diameter of roller &ge; 400 mm;- Equation for power-absorption curve: from an initial speed of 12 km/h, the test bench must be able to reproduce, with a tolerance of ± 15 %, the power developed by the engine when the motorcycle or motor tricycle is travelling along a flat road with wind speed virtually zero. Either the power absorbed by the brakes and the internal friction of the bench must be calculated according to the provisions of section 11 of Sub-appendix 4 to Appendix 1, or the power absorbed by the brakes and the internal friction of the bench are:K V³ ± 5 % of K V³ ± 5 % of PV50- Additional inertias: 10 kg and 10 kg (3).4.1.1. The distance effectively travelled is measured using a revolution counter driven by the roller which drives the brake and the flywheels.4.2. Equipment for sampling the gases and measuring their volume4.2.1. Sub-appendices 2 and 3 contain a diagram showing the principle for collecting, diluting, sampling and measuring the volume of exhaust gases during the test.4.2.2. The following sections describe the components of the test equipment (against each component is given the abbreviation used in the sketch in Sub-appendices 2 and 3). The technical service may authorize the use of different equipment provided that it gives equivalent results:4.2.2.1. a device to collect all the exhaust gases produced during the test; this is generally an open device, which maintains atmospheric pressure at the exhaust pipe(s). Nevertheless, a closed system may be used provided that the back-pressure conditions are complied with (with ± 1,25 kPa). The gases must be collected in such a way that there is not sufficient condensation to have a significant effect on the nature of the exhaust gases at the test temperature;4.2.2.2. a tube (Tu) connecting the exhaust-gas collection equipment and the exhaust-gas sampling system. This connecting tube and the gas-collection equipment must be made of stainless steel, or of another material which will not affect the composition of the gases collected and will resist their temperature;4.2.2.3. a heat exchanger (Sc) capable of limiting the variation in the temperature of the diluted gases at the pump inlet to within ± 5 °C for the duration of the test. This exchanger must be equipped with a pre-heating system capable of bringing the gases up to its operating temperature (with a tolerance of ± 5 °C) before the test commences;4.2.2.4. a displacement pump (P1) to suck in the diluted gases driven by a motor which can operate at various rigorously constant speeds. The pump must guarantee constant flow of a sufficient volume in order to ensure that all the exhaust gases are sucked in. A device which uses a critical float Venturi may also be used;4.2.2.5. a device which can continually record the temperature of the diluted gases entering the pump;4.2.2.6. a sampling probe (S3) attached to the outside of the gas-collection device which can collect a constant sample of the dilution air using a pump, a filter and a flow meter for the duration of the test;4.2.2.7. a sampling probe S2, placed before the displacement pump and directed upstream of the flow of diluted gases to sample the mixture of diluted gases for the duration of the test at a constant rate of flow using, if necessary, a filter, a flow meter and a pump. The minimum rate of flow of the gases in the two sampling systems described above must be at least 150 l/h;4.2.2.8. two filters (F2 and F3), placed after probes S2 and S3 respectively, designed to filter out the solid particles suspended in the flow of the sample collected in the bags. Particular care must be taken to ensure that they do not affect the concentrations of gaseous components in the samples;4.2.2.9. two pumps (P2 and P3) to take samples from probes S2 and S3 respectively and to fill bags Sa and Sb;4.2.2.10. two hand-adjustable valves (V2 and V3) installed in series with pumps P2 and P3 respectively in order to regulate the flow of the sample sent into the bags;4.2.2.11. two rotameters (R2 and R3) installed in series in the lines 'probe, filter, pump, valve, bag` (S2, F2, P2 , V2, Sa and S3, F3, P3, V3 Sb respectively) so that instant visual checks can be made on the flow of the sample at any moment;4.2.2.12. leak-tight sampling bags to collect the dilution air and mixture of diluted gases which are of sufficient capacity not to disrupt the normal flow of sampling. These sampling bags must have automatic sealing devices on the side of the bag which can be closed rapidly and tightly, either on the sampling circuit or on the analysis circuit at the end of the test;4.2.2.13. two differential pressure manometers (g1 and g2) installed:g1: before pump P1 in order to measure the difference in pressure between the mixture of exhaust gases and dilution air and the atmosphere;g2: before and after pump P1 in order to measure the increase in pressure exerted on the flow of gas;4.2.2.14. a revolution counter to count the number of revolutions made by the rotary displacement P1;4.2.2.15. three-way valves on the sampling circuits described above to direct the flow of samples either to the atmosphere or to their respective sampling bags for the duration of the test. Rapid-action valves must be used. They must be manufactured from materials which do not affect the composition of the gases; they must also have discharge cross-sections and shapes which minimize load losses as far as technically possible.4.3. Analytical equipment4.3.1. Measuring the concentration of hydrocarbons4.3.1.1. A flame-ionization analyser is used to measure the concentration of unburnt hydrocarbons in the samples collected in bags Sa and Sb, during the test.4.3.2. Measuring the concentrations of CO and CO24.3.2.1. A non-dispersive infra-red absorption analyser is used to measure the concentrations of carbon monoxide CO and carbon dioxide CO2 in the samples collected in bags Sa and Sb during the test.4.3.3. Measuring the concentration of NOx4.3.3.1. A chemiluminescent analyser is used to measure the concentrations of oxides of nitrogen (NOx) in the samples collected in bags Sa and Sb during the test.4.4. Accuracy of instruments and measurements4.4.1. As the brake is calibrated in a separate test, it is not necessary to indicate the accuracy of the dynamometer. The total inertia of the rotating masses, including that of the rollers and the rotating part of the brake (see 5.2), must be given to within ± 2 %.4.4.2. The speed of the motorcycle or motor tricycle is measured by the speed of rotation of the rollers connected to the brake and the flywheels. It must be measurable to within ± 2 km/h from 0 to 10 km/h and to within ± 1 km/h for speeds above 10 km/h.4.4.3. The temperature referred to in 4.2.2.5 must be measurable to within ± 1 °C. The temperature referred to in 6.1.1 must be measurable to within ± 2 °C.4.4.4. The atmospheric pressure must be measurable to within ± 0,133 kPa.4.4.5. The drop in pressure in the mixture of diluted gases entering pump P1 (see 4.2.2.13) compared with atmospheric pressure must be measurable to within ± 0,4 kPa. The difference in pressure of the diluted gases entering the sections before and after pump P1 (see 4.2.2.13) must be measurable to within ± 0,4 kPa.4.4.6. The volume displaced at each complete rotation of pump P1 and the displacement value at the lowest possible pump speed, as recorded by the revolution counter, must make it possible to determine the overall volume of the mixture of exhaust gases and dilution air displaced by pump P1 during the test to within ± 2 %.4.4.7. Irrespective of the accuracy with which the standard gases are determined, the measuring range of the analysers must be compatible with the accuracy required to measure the content of the various pollutants to within ± 3 %.The flame-ionization analyser which measures the concentration of hydrocarbons must be capable of reaching 90 % of the full scale in less than one second.4.4.8. The content of the standard (calibration) gases must not differ by more than ± 2 % from the reference value of each gas. The diluent must be nitrogen.5. PREPARING THE TEST5.1. Setting of brake5.1.1. The brake must be so adjusted that the speed of the motorcycle or motor tricycle during the steady speed phase is between 45 km/h and 55 km/h on a flat dry road.5.1.2. The brake is adjusted as follows:5.1.2.1. An adjustable stop to keep the maximum speed between 45 km/h and 55 km/h is fitted to the fuel supply device. The speed of the motorcycle or motor tricycle is measured by means of a precision tachometer or deduced from measuring the time over a given distance on a flat dry road in both directions with the stop closed.The measurements must be repeated at least three times in both directions and must be made over a distance of at least 200 m with a sufficiently long acceleration distance. The average speed is calculated.5.1.2.2. Other systems may also be used to measure the power required to propel the vehicle (e.g. measuring the torque on the transmission, measuring deceleration, etc.).5.1.2.3. The motorcycle or motor tricycle must then be placed on the dynamometer and the brake adjusted so as to obtain the same speed as that attained in the road test (with the fuel-regulating device in the stop position and the same gear selected). This brake adjustment must be maintained throughout the test. Once the brake has been adjusted, the fuel-regulating device is removed.5.1.2.4. Setting the brake on the basis of road tests is allowed only if the difference in barometric pressure between the road and the premises in which the dynamometer is housed, does not exceed ± 1,33 kPa and the difference in air temperature is not more than ± 8 °C.5.1.3. If the above method is not applicable, the dynamometer must be set in accordance with the values in the table in 5.2. The table shows power values as a function of reference mass at a speed of 50 km/h. This power is determined using the method described in Sub-appendix 4.5.2. Adjustment of equivalent inertias to the translatory inertias of the motorcycle or motor tricycle.One or more flywheels are used enabling a total inertia of the rotating masses to be obtained proportional to the reference mass of the motorcycle or motor tricycle within the following limits:>TABLE>5.3. Conditioning of the motorcycle or motor tricycle5.3.1. Before the test, the motorcycle or motor tricycle must be kept in a room in which the temperature remains relatively constant between 20 °C and 30 °C. This conditioning must be carried out until the engine oil temperature and coolant, if any, are within ± 2 K of the temperature of the room. After the motor has idled for 40 seconds, two complete cycles are performed before the exhaust gases are collected.5.3.2. The tyre pressure must be that indicated by the manufacturer for performance of the preliminary road test to set the brake. However, if the diameter of the rollers is less than 500 mm, the pressure in the tyres may be increased by 30 %-50 %.5.3.3. The mass on the driven wheel is the same as when the motorcycle or motor tricycle is used under normal driving conditions with a driver weighing 75 kg.5.4. Calibration of analytical apparatus5.4.1. Calibration of analysersThe quantity of gas at the indicated pressure compatible with the correct functioning of the equipment is injected into the analyser by means of the flow meter and discharge gauge mounted on each bottle. The apparatus is adjusted to indicate as a stabilized value, the value shown on the standard gas bottle. Starting from the setting obtained with the maximum-content bottle, the curve of the analyser's deviations is drawn as a function of the content of the various standard gas bottles used. For the regular calibration of flame-ionization analysers, which should be done at least once a month, mixtures of air and propane (or hexane) with rated concentrations of hydrocarbon equal to 50 % and 90 % of the full scale are used. For regular calibration of non-dispersive infra-red absorption analysers, mixtures of nitrogen with CO and CO2 respectively are measured at rated concentrations of 10 %, 40 %, 60 %, 85 % and 90 % of the full scale. For calibration of the chemiluminescent NOx analyser, mixtures of nitrous oxide (N2O) diluted in nitrogen with a nominal concentration of 50 % and 90 % of the full scale are used. For the test calibration, which must be carried out before each series of tests, it is necessary, for all three types of analyser, to use mixtures containing the gases to be measured to a concentration equal to 80 % of the full scale. A dilution device can be used for diluting a 100 % calibration gas to the required concentration.6. PROCEDURE FOR DYNAMOMETER TESTS6.1. Special conditions for carrying out the cycle6.1.1. The temperature in the premises where the dynamometer bench is situated must be between 20 ° and 30 °C throughout the test, and must be as close as possible to the temperature of the premises where the motorcycle or motor tricycle were conditioned.6.1.2. The motorcycle or motor tricycle must as far as possible be horizontal during the test so as to avoid any abnormal distribution of the fuel.6.1.3. At the end of the first 40 second idling period (see 6.2.2), a flow of air of variable speed is directed at the motorcycle or motor tricycle. Two complete cycles are then performed during which no exhaust gases are collected. The ventilation system must include a mechanism controlled by the speed of the bench roller so that, in the range from 10 km/h to 50 km/h, the linear air speed at the blower outlet is equal to the relative speed of the roller with an approximation of 10 %. For roller speeds below 10 km/h the air speed may be zero. The end section of the air blower device must have the following characteristics:i) surface area of at least 0,4 m²;ii) lower edge between 0,15 and 0,20 m above ground level;iii) distance from the leading edge of the motorcycle or motor tricycle between 0,3 and 0,45 m.6.1.4. During the test, speed is plotted against time in order to check that the cycles have been performed correctly.6.1.5. The temperatures of the cooling water and the crankcase oil may be recorded.6.2. Starting up the engine6.2.1. Once the preliminary operations on the equipment for collecting, diluting, analysing and measuring the gases have been carried out (see 7.1), the engine is started up by means of the devices provided for that purpose, such as the choke, the starter valve, etc., according to the manufacturer's instructions.6.2.2. The engine must be kept idling for a maximum of 40 seconds. The first cycle begins when the taking of samples and the measuring of the pump rotations commence.6.3. Use of the manual chokeThe choke must be cut out as soon as possible and in principle before acceleration from 0 to 50 km/h. If this requirement cannot be met, the moment of actual cut-out must be indicated. The choke must be adjusted in accordance with the manufacturer's instructions.6.4. Idling6.4.1. Manual-shift gearbox:6.4.1.1. During periods of idling the clutch must be engaged and the gears in neutral.6.4.1.2. To enable the accelerations to be performed according to the normal cycle the vehicle must be put in first gear, with the clutch disengaged, five seconds before commencement of the acceleration following the idling period in question.6.4.1.3. The first idling period at the beginning of the cycle consists of six seconds of idling in neutral with the clutch engaged and five seconds in first gear with the clutch disengaged.6.4.1.4. For the idling periods during each cycle the corresponding times are 16 seconds in neutral and five seconds in first gear with the clutch disengaged.6.4.1.5. The last idling period in the cycle consists of seven seconds in neutral with the clutch engaged.6.4.2. Semi-automatic gearboxes:the manufacturer's instructions for driving in town, or in their absence instructions applicable to manual gearboxes, must be followed.6.4.3. Automatic gearboxes:the selector must not be operated at any time during the test unless the manufacturer specifies otherwise. In the latter case the procedure for manual gearboxes applies.6.5. Accelerations6.5.1. Accelerations must be effected so as to ensure that the rate of acceleration is as constant as possible throughout the operation.6.5.2. If the acceleration capacities of the motorcycle or motor tricycle are not sufficient to perform the acceleration cycles within the prescribed tolerances, the motorcycle or motor tricycle must be driven with the throttle completely open until the speed prescribed for the cycle has been reached; the cycle may then continue normally.6.6. Decelerations6.6.1. All decelerations must be effected by completely closing the throttle, the clutch remaining engaged. The engine must be disengaged at a speed of 10 km/h.6.6.2. If the period of deceleration is longer than that prescribed for the corresponding phase, the vehicle's brakes are used to keep to the cycle.6.6.3. If the period of deceleration is shorter than that prescribed for the corresponding phase, the timing of the theoretical cycle is restored by a steady-state or an idling period merging into the following steady-state or idling operation. In this case, section 2.4.3 is not applicable.6.6.4. At the end of the deceleration period (stopping motorcycle or motor tricycle on the rollers) the gear is put into neutral and the clutch engaged.6.7. Steady speeds6.7.1. 'Pumping` or the closing of the throttle must be avoided when passing from acceleration to the following steady speed.6.7.2. Periods of constant speed must be achieved by keeping the accelerator position fixed.7. PROCEDURE FOR SAMPLING, ANALYSING AND MEASURING THE VOLUME OF EMISSIONS7.1.

The dynamometer is operated above the range of test speeds. The device used to activate the dynamometer is then disconnected from the bench and the rotational speed of the roller(s) decreases.The kinetic energy of the device is dissipated by the dynamometer power absorption unit and by the friction of the dynamometer. This method takes no account of variations in internal friction within the roller due to the rotating mass of the motorcycle or motor tricycle. The difference between the time the free rear-roller stops and the time the motor-driven front roller stops can be ignored in the case of a dynamometer with two rollers.Procedures are as follows:1. The rotational speed of the roller is measured if this has not already been done. An additional measuring wheel, a revolution counter, or another method may be used.2. The motorcycle or motor tricycle is placed on the dynamometer or another method is used to make the dynamometer function.3. The flywheel, or any other of the inertia simulation systems most commonly used with the dynamometer for the particular category of motorcycle or motor tricycle mass, is engaged.4. The dynamometer is brought to a speed of 50 km/h.5. The power absorbed is recorded.6. The dynamometer is brought to a speed of 60 km/h.7. The device used to activate the dynamometer is disconnected.8. The time taken for the dynamometer to decrease from a speed of 55 km/h to a speed of 45 km/h is recorded.9. The power absorption device is set to a different level.10. Stages 4 to 9 above are repeated as often as required to cover the range of the on-road powers used.11. The absorbed power is calculated by means of the formula:Pd =  >NUM>M1 (V1² - V2²) >DEN> 2 000 t =   >NUM>0,03858 M1 >DEN>twhere:Pd = power in kWM1 = equivalent inertia in kgV1 = initial velocity in m/s (55 km/h = 15,28 m/s)V2 = final velocity in m/s (45 km/h = 12,50 m/s)t = time taken by the roller to decelerate from 55 km/h to 45 km/h12.

INTRODUCTIONProcedure for Type II test specified in section 2.2.1.2. of Annex II.2. MEASUREMENT CONDITIONS2.1. The fuel used is that prescribed in Annex IV.2.2. The concentration by volume of carbon monoxide must be measured immediately after the Type I test with the engine at idling speed.2.3. In the case of motorcycles or motor tricycles with manual or semi-automatic gearboxes, the test is carried out with the gear lever in the 'neutral` position and with the clutch engaged.2.4. In the case of motorcycles or motor tricycles with automatic transmissions, the test is carried out with the selector in position 'zero` or 'park`.3. SAMPLING OF GASES3.1. The exhaust outlet must be fitted with a sufficiently leak-tight extension piece so that the exhaust-gas sampling probe can be inserted to at least 60 cm without increasing back-pressure by more than 1,25 kPa and without affecting operation of the motorcycle or motor tricycle. Nevertheless, the shape of the extension piece must be such as to avoid appreciable dilution of exhaust gases by air at the point of the sampling probe. If the motorcycle or motor tricycle is equipped with more than one exhaust outlet, either these outlets must be connected up to a common pipe or carbon monoxide concentrations must be tested at each outlet, with the results of the measurements being the arithmetical mean of these concentrations.3.2. The concentrations of CO(CCO) and CO2 (CCO²) are determined by reading off the results shown by the instruments or recording devices and using the appropriate calibration tables.3.3. The corrected concentration of carbon monoxide in two-stroke engines is:CCO corr = CCO  >NUM>10 >DEN>CCO + CCO² (% vol.)3.4. The corrected concentration of carbon monoxide in four-stroke engines is:CCO corr = CCO  >NUM>15 >DEN>CCO + CCO² (% vol.)3.5. It is not necessary to correct the concentration of CCO (3.2) measured according to the formulae given in 3.3 or 3.4 if the sum of the concentrations measured (CCO + CCO²) is 10 or more for two-stroke engines or 15 or more for four-stroke engines.(1) >START OF GRAPHIC> n Ó (xi - x)² >END OF GRAPHIC>S² =  >NUM>i = 1 >DEN>nwhere xi is any one of the individual results obtained with sample n and>START OF GRAPHIC> n Ó xi >END OF GRAPHIC>>START OF GRAPHIC> x >END OF GRAPHIC> =  >NUM>i = 1 >DEN>n(2) These are additional masses which may where appropriate be replaced by an electronic device, provided that the equivalence of the results is demonstrated.ANNEX III SPECIFICATIONS FOR MEASURES TO BE TAKEN AGAINST VISIBLE AIR POLLUTION CAUSED BY TWO- OR THREE-WHEEL MOTOR VEHICLES EQUIPPED WITH A COMPRESSION-IGNITION ENGINE 1. DEFINITIONFor the purposes of this Chapter:1.1. 'Vehicle type` means motor vehicles which do not differ in essential respects as regards the characteristics of the vehicle and the engine as defined in Annex V.2. TEST SPECIFICATIONS2.1. GeneralThe components liable to affect the emission of visible pollutants must be designed, constructed and assembled so as to enable the vehicle, in normal use, despite the vibration to which it may be subjected, to continue to comply with the requirements of this Annex.2.2. Specifications of cold-starting device2.2.1. The cold-starting device must be designed and constructed in such a way that it cannot continue to operate or be put into operation whilst the engine is operating normally.2.2.2. The provisions of 2.2.1 do not apply if one or more of the following conditions is met:2.2.2.1. While the cold-starting device is in operation, the light-absorption coefficient of the gases emitted by the engine under steady-state operation, as measured by the procedure laid down in Appendix 1, must remain within the limits set out in Appendix 3.2.2.2.2. Continued operation of the cold-starting device causes the motor to stop after a reasonable period.2.3. Specifications concerning emissions of visible pollutants2.3.1. Emissions of visible pollutants by the type of vehicle presented for type-approval are measured using the two methods described in Appendices 1 and 2, which respectively describe tests under steady-state operation and tests under free acceleration.2.3.2. Emissions of visible pollutants measured according to the method described in Appendix 1 must not exceed the limits laid down in Appendix 3.2.3.3. In the case of an engine with turbocharger, the absorption coefficient measured under acceleration in neutral must not exceed the limit laid down in Appendix 3 for the rated flow value which corresponds to the maximum absorption coefficient measured under steady-state operation tests plus 0,5 m-1.2.3.4. The use of equivalent measuring equipment is allowed. If equipment other than that described in Appendix 4 is used, proof must be given of its equivalence for the type of engine concerned.3. CONFORMITY OF PRODUCTION3.1. The requirements of section 1 of Annex VI to Directive 92/61/EEC are applicable for checks on the conformity of production.3.2. In order to verify conformity as prescribed in 3.1, a vehicle is taken from the series.3.3. Conformity of the vehicle with the type approved is verified on the basis of the description given in the approval form. In addition, verifying tests are carried out in the following conditions:3.3.1. A vehicle which has not been run in is subjected to the test under free acceleration prescribed in Appendix 2.The vehicle is deemed to conform to the type approved if the absorption coefficient determined does not exceed by more than 0,5 m-1 the corrected value for the absorption coefficient given in the approval form. At the request of the manufacturer, commercially available fuel may be used rather than the reference fuel. In the case of dispute, reference fuel must be used.3.3.2. In the figure determined in the test referred to in 3.3.1 exceeds by more than 0,5 m-1 the figure shown in the approval form, the engine of the vehicle is subjected to the test at steady speeds over the full-load curve, as prescribed in Appendix 1. The visible emission levels must not exceed the limits prescribed in Appendix 3.Appendix 1 Steady-state operation test over the full-load curve1. INTRODUCTION1.1. Procedure for determining emissions of visible pollutants under different conditions of steady-state operation over the full-load curve.1.2. The test may be performed either on an engine or on a vehicle.2. PRINCIPLE OF MEASUREMENT2.1. The opacity of the exhaust gases produced by the engine operating at full load under steady-state conditions is measured.2.2. At least six measurements ranging from the maximum rated speed to the minimum rated speed are made. The extreme measuring points are at the two extremities of the interval defined above, and one measuring point must coincide with the speed at which the engine develops maximum power and the speed at which it develops maximum torque.3. TEST CONDITIONS3.1. Motor vehicle3.1.1. The engine or the vehicle must be presented in good mechanical condition. The engine must have been run in.3.1.2. The engine is tested with the equipment specified in Annex V.3.1.3. When an engine is tested, its power is measured in accordance with the separate Directive on maximum power, taking into account the tolerances laid down in 3.1.4. When a vehicle is tested, checks are made to ensure that the fuel flow-rate is no lower than that specified by the manufacturer.3.1.4. As regards the power of the engine measured on the dynamometer during steady-state operation testing over the full-load curve, the following tolerances are allowed in relation to the power declared by the manufacturer:- maximum power ± 2 %- at other measuring points + 6 % / - 2 %.3.1.5. The exhaust device must not have any leaks likely to dilute the gases emitted by the engine. If an engine has more than one exhaust outlet, they must be linked up to one single outlet at which the opacity is measured.3.1.6. The settings of the engine must be those prescribed by the manufacturer for normal use. In particular, the cooling water and oil must both be at the normal temperatures prescribed by the manufacturer.3.2. FuelA reference diesel fuel in accordance with the specifications set out in Annex IV is used for the test.3.3. Test laboratory3.3.1. The absolute temperature T, expressed in K, of the air (1) admitted into the engine is measured no more than 15 cm before the air is admitted to the air filter or, if there is no air filter, no more than 15 cm from the air intake. Dry atmospheric pressure ps, expressed in kPa, is also measured and the atmospheric factor fa shall be determined in accordance with the following provisions:>START OF GRAPHIC>fa = ( 99 ps ) 0,65  7 ( T 298 ) 0,5 >END OF GRAPHIC>where:ps = pb - pìpb = barometric pressurepì = water vapour pressure3.3.2. If a test is to be recognized as valid, the parameter fa must be such that 0,98 4. EVALUATING THE LIGHT-ABSORPTION COEFFICIENT4.1. The nominal flow of gas is calculated for each of the rotation speeds for which the absorption coefficient is measured in accordance with section 2.2 by means of the following formula:- two stroke engines G =  >NUM>Vn >DEN>60- four stroke engines G =  >NUM>Vn >DEN>120where:G = the nominal flow of gas in litres per second (l/s)V = the cylinder capacity expressed in litres (l)n = the rotation speed expressed in rpm4.2. If the nominal flow value does not correspond with one of the values given in the table in Appendix 3, the limit value to be used is determined by interpolating a proportional value.Appendice 2 Free-acceleration test1. TEST CONDITIONS1.1. Tests are performed on an engine installed on a dynamometer or on a vehicle.1.1.1. If the engine is tested on a dynamometer, it must be tested as soon as possible following the test to check opacity under steady-state operation over the fuel-load curve. In particular the cooling water and oil must both be at the normal temperatures prescribed by the manufacturer.1.1.2. If the engine is tested on a stationary vehicle, the engine must first be operated under its normal operating conditions either on the road or in a dynamic test. The measuring test must be conducted as soon as possible after the end of this warming-up period.1.2. The combustion chamber must not have been cooled or clogged by excessive idling before the test.1.3. The test conditions set out in sections 3.1., 3.2 and 3.3 of Appendix 1 apply.1.4. The conditions concerning the sampling and measuring equipment set out in section 3.4 of Appendix 1 apply.2. TEST PROCEDURE2.1. When the test is carried out on a dynamometer, the engine is disconnected from the brake, this being replaced either by the driven rotating parts when the gearbox is in neutral, or by an inertia that is perceptibly equivalent to that of those parts.2.2. When the test is carried out on a vehicle, the gearbox control must be in neutral and the clutch engaged.2.3. With the engine idling, the accelerator is operated rapidly but gently in order to obtain maximum flow from the injection pump. This position is maintained until maximum engine speed has been achieved and the governor cuts in. As soon as this speed has been reached, the accelerator is released until the engine returns to idling speed and the opacimeter again registers accordingly.2.4. The operation described in 2.3 is repeated at least six times in order to clear the exhaust system and, if necessary, in order to reset the measuring equipment. The maximum opacity values obtained at each successive acceleration are recorded until a stabilized value is obtained. No account is taken of values recorded during the idling period following each acceleration period. Values are considered to have stabilized when four consecutive values come within a range of no more than 0,25 m-1 and do not form a decreasing series. The absorption coefficient XM recorded is the arithmetic mean of these four values.2.5. Engines equipped with a turbocharger must, where appropriate, be governed by the following special conditions:2.5.1. In the case of engines equipped with a turbocharger which is either driven by a coupler or is driven mechanically by the engine and may be disconnected, two complete measuring cycles are performed with preliminary acceleration, the compressor being connected for one and disconnected for the other; the measurement result adopted is the higher of the two;2.5.2. If the engine has more than one exhaust outlet, the tests are performed by combining all the outlets in one suitable device to mix the gases together and discharge them through one sole outlet; however, tests under free acceleration may be performed at each of the outlets, in which case the value used to calculate the corrected absorption coefficient is the arithmetic mean of the values recorded at each outlet and the test is considered valid only if the extreme values measured do not differ by more than 0,15 m-1.3. DETERMINATION OF THE CORRECTED VALUE FOR THE ABSORPTION COEFFICIENTThese provisions apply if the absorption coefficient under steady-state operation has actually been arrived at on the same derivative engine type.3.1. Symbols>TABLE>3.2. Since absorption coefficients are expressed in m-1, the corrected value XL is given by the smaller of the following two expressions:XL =  >NUM>SL  7 XM >DEN>SMorXL = XM + 0,5Appendix 3 >TABLE>Appendix 4 Specifications for opacimeters1. SCOPEThis Appendix defines the conditions which must be met by the opacimeters used in the tests described in Appendices 1 and 2.2. BASIC SPECIFICATIONS FOR OPACIMETERS2.1. The gas to be measured must be contained in a chamber with a non-reflecting internal surface.2.2. The effective length of the passage of rays of light through the gas being measured is determined taking into account the possible effect of the devices to protect the light source and the photoelectric cell. This length must be indicated on the apparatus.2.3. The opacimeter's measurement indicator must have two scales, one in absolute units of light absorption from 0 to >START OF GRAPHIC>&infin;>END OF GRAPHIC> (m-1) and the other a linear scale from 0 to 100; on both scales 0 indicates total light and the maximum total absence of light.3. MANUFACTURING SPECIFICATIONS3.1. GeneralThe opacimeter must be such that, under steady-state operating conditions, the smoke chamber is full of smoke with uniform opacity.3.2. Smoke chamber and opacimeter housing3.2.1. The possibility of unwanted light reaching the photoelectric cell as a result of internal reflection or the effects of diffusion must be kept to a minimum (e.g. by colouring internal surfaces matt black and arranging them in a suitable way).3.2.2. The optical characteristics must be such that the combined effect of diffusion and reflection does not exceed one unit on the linear scale when the smoke chamber is full of smoke with an absorption coefficient in the region of 1,7 m-1.3.3. Light sourceThe light source must be an incandescent lamp with a colour temperature between 2 800 and 3 250 K.3.4. Receiver3.4.1. The receiver consists of a photoelectric cell with a spectral response curve similar to the photopic curve of the human eye (maximum response in the 550/570 nm band, less than 4 % of this maximum response below 430 nm and above 680 nm).3.4.2. Construction of the electrical circuit containing the measurement indicator must be such that the output current of the photoelectric cell is a linear function of the intensity of light received in the range of operating temperatures of the photoelectric cell.3.5. Measurement scale3.5.1. The light absorption coefficient k is calculated by means of the formula Ø = Ø0  7 e-KL, where L is the effective length of the passage of light beams through the gas being measured, Ø0 is the flow of light in and Ø is the flow of light out. When the effective length L of a type of opacimeter may not be evaluated directly according to its geometry, the actual length L is determined;- either by the method described in section 4, or- by comparison with another type of opacimeter whose actual length is known.3.5.2. The relation between the linear scale from 0 to 100 and the absorption coefficient k is arrived at by means of the following formula:k =  >NUM>-1 >DEN> Lloge (1 -  >NUM>N >DEN>100)where N is the reading on the linear scale and k the corresponding absorption coefficient value.3.5.3. The measurement indicator of the opacimeter must allow reading of an absorption coefficient of 1,7 m-1 with an accuracy of 0,025 m-1.3.6. Setting and testing the measuring equipment3.6.1. The electrical circuit of the photoelectric cell and the indicator must be adjustable so that the needle can be set to zero when the flow of light passes through a smoke chamber filled with clean air or a chamber with identical characteristics.3.6.2. With the lamp off and the electrical measuring circuit off or short-circuited, the reading from the scale of absorption coefficients is &infin; and, with the measuring circuit on gain the value must remain &infin;.3.6.3. An intermediate check is carried out by placing in the smoke chamber a filter which represents a gas whose absorption coefficient, k, measured as described in 3.5.1, is known to be between 1,6 m-1 and 1,8m-1. The k value must be known to within 0,025 m-1. The check is designed to ensure that the value differs by no more than 0,05 m-1 from that shown on the measurement indicator once the filter has been inserted between the light source and the photoelectric cell.3.7. Opacimeter response3.7.1. The response time of the electrical measuring circuit, which is the time it takes for the indicator to reach a total deflection of 90 % of the full scale when a screen is inserted which fully obscures the photoelectric cell, must be between 0,9 and 1,1 seconds.3.7.2. Damping of the electrical measuring circuit must be such that the initial exceeding of the final stable value after any momentary variation in the input value (e.g. the check filter) is no more than 4 % of this value in the units in the linear scale.3.7.3. the response time of the opacimeter to physical phenomena in the smoke chamber, which is the period of time between the gases first entering the measuring device and the gases completely filling the smoke chamber, must not be more than 0,4 seconds.3.7.4. These provisions apply only to opacimeters used to measure opacity under free acceleration.3.8. Pressure of the gas to be measured and the scavenging air.3.8.1. The pressure of the exhaust gases in the smoke chamber must not differ from that of the ambient air by more than 0,75 kPa.3.8.2. Variations in the pressure of the gases being measured and the scavenging air must not cause the absorption coefficient to vary by more than 0,05 m-1 for a gas corresponding to an absorption coefficient of 1,7 m-1.3.8.3. The opacimeter must be fitted with devices capable of measuring the pressure in the smoke chamber.3.8.4. The manufacturer of the appliance must indicate the limits in variation of the pressure of the gas and the scavenging air in the smoke chamber.3.9. Temperature of the gas being measured3.9.1. Throughout the smoke chamber, the temperature of the gas at the time of measurement must be between 70 °C and a maximum temperature specified by the manufacturer of the opacimeter, such that readings over this range of temperatures do not vary by more than 0,1 -1 when the chamber is full of a gas with an absorption coefficient of 1,7 m-1.3.9.2. The opacimeter must be equipped with devices to measure temperatures in the smoke chamber.4. EFFECTIVE LENGTH 'L` OF THE OPACIMETER4.1. General4.1.1. In certain types of opacimeter, the gases between the light source and the photoelectric cell, or between the transparent components protecting the light source and the photoelectric cell, do not have constant opacity. In these cases the effective length L is that of a column of gas of uniform opacity resulting in the same light absorption as that observed when the gas passes through the opacimeter normally.4.1.2. The effective length of the passage of the light rays is obtained by comparing the reading N on the opacimeter operating normally with the reading N° obtained with the opacimeter modified so that the test gas fills a carefully defined length L°.4.1.3. Comparative readings must be taken in rapid succession in order to determine the correct place of zero.4.2. Method of evaluating L4.2.1. The test gases are the exhaust gases with constant opacity or absorbent gases with a density in the order of that of the exhaust gases.4.2.2. A column L° of the opacimeter which may be uniformly filled with the test gases and with bases more or less perpendicular to the direction of the light rays must be determined accurately. This length L° must be close to the supposed effective length of the opacimeter.4.2.3. The average temperature of the test gases in the smoke chamber is measured.4.2.4. If necessary, an expansion vessel with sufficient capacity to neutralize pulsations and of compact shape may be incorporated into the sampling line, as near the probe as possible. A cooling device may also be installed. Addition of an expansion vessel and a cooling device must not unduly affect the composition of the exhaust gases.4.2.5. The test to determine effective length consists in passing a sample of test gas alternately through the opacimeter operating normally and through the same apparatus modified as described in 4.1.2.4.2.5.1. The readings given by the opacimeter are recorded on a continuous basis during the test with a recording device whose response time is as equivalent to that of the opacimeter as possible.4.2.5.2. With the opacimeter operating normally, the reading on the linear scale is N and that of the average temperature of the gases expressed in Kelvins is T.4.2.5.3. With the known length L° filled with the same test gas, the reading on the linear scale is N° and that of the average temperature of the gases expressed in Kelvins is T°.4.2.6. The effective length is:L = L°  >NUM>T >DEN>T° >NUM>log (1 -  >NUM>N >DEN>100) >DEN>log (1 -  >NUM>N° >DEN> 10)4.2.7. The test is repeated with at least four test gases to give readings spaced regularly along a linear scale from 20 to 80.4.2.8. The effective length L of the opacimeter is the arithmetic mean of the effective lengths obtained as defined in 4.2.6 with each of the test gases.Appendix 5 Installation and use of the opacimeter1. SCOPEThis Appendix contains specifications for the installations and use of opacimeters designed for use in the tests described in Appendices 1 and 2.2. SAMPLING OPACIMETER2.1. Installation for steady-state testing2.1.1. The ratio between the surface area of the section of the probe and that of the exhaust pipe must be at least 0,05. The back-pressure measured in the exhaust pipe at the probe inlet must not exceed 0,75 kPa.2.1.2. The probe is a tube with its open end facing forwards in the axis of the exhaust pipe, or of the extension piece if used. It is placed in a section where distribution of the gas is approximately uniform. In order to achieve this, the probe must be placed as far downstream of the exhaust pipe as possible, or extension piece if used, so that, if D is the diameter of the exhaust pipe at its outlet, the end of the probe is placed in a rectilinear section having a length of at least 6 D upstream of the sampling point and 3 D downstream. If an extension tube is used no air must be allowed to enter at the joint.2.1.3. The pressure in the exhaust pipe and the nature of the drop in pressure in the sampling line must be such that the probe collects a sample which is virtually equivalent to that which would be obtained by isokinetic sampling.2.1.4. If necessary, an expansion vessel of compact shape and with sufficient capacity to neutralize any pulsations may be incorporated into the sampling line, as near the probe as possible. A cooling device may also be installed. The expansion vessel and the cooling device must be so designed that they do not unduly affect the composition of the exhaust gases.2.1.5. A butterfly valve, or another means of increasing the sampling pressure, may be fitted inside the exhaust pipe at least 3 D downstream of the sampling probe.2.1.6. The pipes between the probe, the cooling device, the expansion vessel (if used) and the opacimeter must be as short as possible, whilst meeting the pressure and temperature requirements laid down in sections 3.8 and 3.9 of Appendix 4. The pipes must slope upwards from the sampling point to the opacimeter and there must be no sharp bends where soot can accumulate. If not incorporated in the opacimeter, a bypass valve is fitted upstream.2.1.7. During the test, checks must be made to ensure that the provisions of section 3.8 of Appendix 4 on pressure and those of 3.9 on temperature in the measuring chamber are being met.2.2. Installation for tests under free acceleration2.2.1. The ratio between the surface area of the section of the probe and that of the exhaust pipe must be at least 0,05. The back-pressure measured in the exhaust pipe at the probe inlet must not exceed 0,75 kPa.2.2.2. The probe is a tube with its open end facing forwards in the axis of the exhaust pipe, or of the extension piece if used. It is placed in a section where distribution of the gas is approximately uniform. In order to achieve this, the probe must be placed as far downstream of the exhaust pipe as possible, or extension piece if used, so that, if D is the diameter of the exhaust pipe at its outlet, the end of the probe is placed in a rectilinear section having a length of at least 6 D upstream of the sampling point and 3 D downstream. If an extension tube is used no air must be allowed to enter at the joint.2.2.3. The sampling system must be such that at all engine speeds the pressure of the sample in the opacimeter is within the limits laid down in section 3.8.2 of Appendix 4. This can be checked by noting the pressure of the sample at idling speed and at maximum speed under no load. Depending on the type of opacimeter, the pressure of the sample can be controlled by installing a collar or a butterfly valve in the exhaust pipe or the extension piece. Whatever the method used, the back-pressure measured in the exhaust pipe at the probe inlet must not exceed 0,75 kPa.2.2.4. The pipes connected to the opacimeter must be as short as possible. The pipe must slope upwards from the sampling point to the opacimeter and there must be no sharp bends where soot can accumulate. A bypass valve may be installed before the opacimeter to isolate the exhaust gases, except when measurements are being taken.3. TOTAL FLOW OPACIMETERThe only general precautions to be observed for tests under steady state operation and under free acceleration are as follows:3.1. The pipes connecting the exhaust system and the opacimeter must be such that no outside air may enter.3.2. The opacimeter connection pipes must be as short as possible as for the sampling opacimeters. The pipes must slope upwards from the exhaust pipe to the opacimeter and there must be no sharp bends where soot can accumulate. A bypass valve may be installed before the opacimeter to isolate the flows of exhaust gases, except when measurements are being taken.3.3. A cooling system upstream of the opacimeter may also be necessary.(1) The test may be performed in an air-conditioned test cell where the atmospheric conditions can be controlled.ANNEX IV >TABLE>>TABLE>ANNEX V INFORMATION DOCUMENT IN RESPECT OF MEASURES TO BE TAKEN AGAINST AIR POLLUTION CAUSED BY A TYPE OF TWO OR THREE-WHEEL MOTOR VEHICLE (1) >START OF GRAPHIC>(To be attached to the component type-approval application where this is submitted separately from the vehicle type-approval application)Order No (assigned by the applicant): ..........The component type-approval application in respect of measures to be taken against air pollution caused by a type of two or three-wheel motor vehicle must contain the information set out in Annex II to Directive 92/61/EEC of 30 June 1992, Part A, in sections:0.1,0.2,0.4 to 0.6,2. to 2.3.2,3. to 3.2.2,3.2.4 to 3.2.4.4,3.2.6 to 3.2.6.7,3.2.7 to 3.2.13,3.5 to 3.6.3.1.2,4. to 4.6.>END OF GRAPHIC>(1) The manufacturer must supply data equivalent to those set out below for conventional engines or systems.ANNEX VI COMPONENT TYPE-APPROVAL CERTIFICATE IN RESPECT OF MEASURES TO BE TAKEN AGAINST AIR POLLUTION CAUSED BY A TYPE OF TWO OR THREE-WHEEL MOTOR VEHICLE >START OF GRAPHIC>Name of administrationReport No: ..........by technical service: ..........Date: ..........Component type-approval: ..........Extension No: ..........1.

GENERAL1.0. For the purpose of this Chapter, 'fuel tank type` means fuel tanks produced by the same manufacturer and the aspects of design, construction and material of which do not differ in any essential respects.1.1. Fuel tanks must be made with materials the thermal, mechanical and chemical behaviour of which continue to be appropriate under their intended conditions of use.1.2. Fuel tanks and the adjacent parts must be designed in such a way as not to generate any electrostatic charge which could cause sparking between the tank and the chassis of the vehicle which would be likely to ignite the fuel/air mixture.1.3. Fuel tanks must be made in such a way as to withstand corrosion. They must pass the leak-tightness tests carried out at a pressure that is twice the relative service pressure and, in any case, is at least equal to an absolute pressure of 130 kPa. Any excess pressure or any pressure exceeding the service pressure must be automatically released by appropriate devices (orifices, safety valves, etc.). The ventilation orifices must be designed in such a way as to preclude any risk of ignition. The fuel must be unable to flow from the filler cap or any devices fitted in order to release excess pressure even if the tank is fully inverted; dripping is tolerated to a maximum of 30 g/min.2. TESTSFuel tanks made of anything other than metal are tested as described below and in the order shown:2.1. Permeability test2.1.1. Test methodThe fuel tank must be tested at a temperature of 313 K ± 2 K. The test fuel to be used in the reference fuel defined in chapter 5 on measures to counter atmospheric pollution by two or three-wheel motor vehicles.The tank is filled up to 50 % of its rated capacity with the test fuel and allowed to rest in the ambient air at a temperature of 313 K ± 2 K until there is a constant weight loss. That period must be at least four weeks (pre-storage period). The tank is emptied and then refilled to 50 % of its rated capacity with test fuel.The tank is then stored under the stabilizing conditions at a temperature of 313 K ± 2 K until its contents are at the test temperature. The tank is then closed. The pressure rise in the tank during the test may be compensated. The weight loss due to diffusion must be determined during the eight-week test. During that test a maximum quantity of 20 g may escape, on average, every 24 hours. If the diffusion losses are greater, the fuel loss must also be determined at a test temperature of 296 K ± 2 K, all other conditions being maintained (pre-storage at 313 K ± 2 K). The loss determined under those conditions must not exceed 10 g per 24 hours.When the test it conducted with internal pressure compensation, which must be mentioned in the test report, the fuel loss resulting from the pressure compensation must be taken into account when the diffusion loss is established.2.2. Shock test2.2.1. Test methodThe fuel tank is filled up to its nominal capacity with a mixture of 50 % water and ethylene glycol or with any other coolant which does not attack the fuel tank material, the cryoscopic point of which is lower than 243 K ± 2 K.The temperature of the substances contained in the fuel tank during the test must be 253 K ± 5 K. The tank is cooled down at a corresponding ambient temperature. It is also possible to fill the fuel tank with a suitably refrigerated liquid provided that the fuel tank is left at the test temperature for at least an hour.A pendulum is used for the test. Its impact head must take the form of an equilateral triangular pyramid having a radius of curvature of 3,0 mm at its peaks and edges. With a mass of 15 kg the pendulum's energy may not be less than 30,0 J.The points on the fuel tank to be tested must be those considered at risk as a result of the fitting of the tank and its position on the vehicle. There must be no liquid leakage following a single impact at one of those points.2.3. Mechanical strength2.3.1. Test methodThe fuel tank is filled up to its rated capacity, the test liquid used being water at 326 K ± 2 K. The relative internal pressure must not be less than 30 kPa. Where the fuel tank has been designed to withstand relative internal pressure of use greater than 15 kPa, the relative test pressure to be applied must be double the relative internal use pressure for which the tank has been designed. The tank must remain closed for a period of 5 hours.Any deformation which may arise may not render the fuel tank unusable. (For example, the tank must not be perforated). Account must be taken of specific fitting conditions if the deformation of the tank is to be assessed.2.4. Fuel-resistance test2.4.1. Test methodSix tensile test-pieces of approximately the same thickness are taken from the flat faces. Their tensile strength and elastic limits are established at 296 K ± 2 K at an elongation rate of 50 mm/min. These values must be compared with the tensile strength and elasticity values obtained via similar tests using a fuel tank that has already been stored for the pre-storage period. The material must be considered to be acceptable if there has been no difference in tensile strength of more than 25 %.2.5. Fire-resistance test2.5.1. Test methodThe tank material must not burn at a flame speed greater than 0,64 mm/s in the test set out in Appendix 1.2.6. High-temperature test2.6.1. Test methodThe fuel tank, filled to 50 % of its rated capacity with water at 293 K ± 2 K, must not display plastic deformation or leaks after storage for one hour at an ambient temperature of 343 K ± 2 K. After the test, the tank must always be fully usable. The testing device must take account of the fitting conditions.Appendix 1 1. TEST EQUIPMENT1.1. Test chamberA totally enclosed laboratory fume hood with a heat-resistant test-observation window. A mirror may be used in certain test enclosures in order to provide a rear view of the sample.The fume extractor fan must be shut down during the test and restarted immediately after the test in order to remove any toxic combustion products.The test may also be carried out inside a metal box placed beneath the fume hood with the extractor fan operating.The top and bottom walls of the box must incorporate ventilation holes enabling sufficient air for the combustion to pass through while not subjecting the burning sample to a draught.1.2. Supporting baseA laboratory supporting base including two grips which can be set in any position by means of swivel joints.1.3. BurnerA gas-fired Bunsen (or Tirill) type with a 10 mm nozzle.The nozzle must not be fitted with any accessory.1.4. Metal meshMesh size 20. Square of 100 × 100 mm.1.5. TimerA timer or similar device with divisions not greater than 1 second.1.6. Water bath1.7. Graduated scaleGraduation in millimetres.2. TEST SAMPLE2.1. At least 10 test samples 125 ± 5 mm long × 12,5 ± 0,2 mm wide must be taken direct from a typical fuel tank.If otherwise prevented by the shape of the fuel tank, part of the tank must be moulded into a plate that is 3 mm thick and sufficient in area to enable the necessary samples to be taken.2.2. The samples must normally be tested in their type-approval state, unless otherwise specified.2.3. Two lines, one at 25 mm and the other at 100 mm from one end must be cut into each sample.2.4. The edges of the test samples must be sharply defined. Edges obtained by sawing must be fine-sanded down in order to obtain a smooth finish.3. TEST METHOD3.1. The sample is attached to one of the grips on the base by the end closest to the 100 mm mark, its longitudinal axis being horizontal and its transverse axis at 45° to the horizontal. Below the test sample a (roughly 100 × 100 mm) woven metal screen is attached and located 10 mm horizontally below the edge of the sample such that the sample protrudes approximately 13 mm beyond the end of the screen (see Figure 1). Before each test, any residue remaining on the metal screen must be burnt or the screen replaced.A bath full of water must be placed on the fume hood table in such a way as to receive any incandescent particles which may fall during the test.3.2. The air supply to the burner must be set in such a way as to obtain a blue flame roughly 25 mm high.3.3. The burner must be placed such that its flame touches the outer edge of the test sample as shown in Figure 1 and at the same time the timer is started.The flame is held in contact for 30 seconds and if the sample deforms, melts or shrinks away from the flame, the flame must be moved in order to maintain contact with the sample.Significant deformation of the sample during the test may invalidate the result. The burner must be withdrawn after 30 seconds or when the flame front reaches the 25 mm mark. If it reaches this earlier the burner must be moved at least 450 mm away from the sample and the fume hood closed.3.4. When the flame front reach the 25 mm mark, the time in seconds must be noted on the timer as time t1.3.5. The timer is stopped when combustion (with or without flame) stops or reaches the mark 100 mm from the free end.3.6. The time on the timer, in seconds, is noted as time t.3.7. If the combustion does not reach the 100 mm mark the unburnt length from the 100 mm mark along the lower edge of the sample is measured, rounded up or down to the nearest millimetre.The burnt length must be equal to 100 mm less the unburnt length expressed in mm.3.8. If a sample has burnt up to or beyond the 100 mm mark the combustion speed must be: >NUM>75 >DEN>t - t1 in mm/s3.9. The test is repeated (3.1 to 3.8) until three samples have burnt up to or beyond the 100 mm mark or ten samples have been tested.If one sample out of 10 burns up to the 100 mm mark or beyond, the test (3.1 to 3.8) is repeated on 10 new samples.4. EXPRESSION OF RESULTS4.1. If at least two samples have burnt up to the 100 mm mark the average speed of combustion (in mm/s) which must be stated is the average of the combustion speeds of all of the samples that have burnt up to the mark.4.2. The average combustion time and length of combustion must be stated if no sample out of ten or not more than 1 out of 20 has burnt up to the 100 mm mark.4.2.1. Average Combustion Time (ACT) in seconds:>START OF GRAPHIC>ACT =nÓi = 1 7(t i - 30)n >END OF GRAPHIC>where n is the number of samplesrounded up or down to the nearest 5-second multiple: thus 'less than 5 seconds` must be stated if combustion lasts less than 3 seconds following withdrawal of the burner.In no case must an ACT of 0 be given.4.2.2. Average Combustion Length (ACL) in millimetres:>START OF GRAPHIC>ACL =nÓi = 1 7(100 - unburnt lengthi)n>END OF GRAPHIC>where n is the number of samplesrounded up or down to the nearest multiple of 5 mm; where there are combustion lengths of less than 3 mm state 'less than 5 mm`.In no case must an ACL of 0 be given.Where a single sample burns up to the mark the combustion length is counted as 100 mm.4.3. The complete results must include the following information:4.3.1. Identification of the sample, including the method of preparation and storage.4.3.2. Average sample thickness to be ± 1 %.4.3.3. Number of samples tested.4.3.4. Dispersion of the combustion time values.4.3.5. Dispersion of the combustion length values.4.3.6. If a sample does not burn up to the mark because it drips, runs or breaks up into burnt particles this must be stated.4.3.7. If a sample is reignited by burning material deposited on the woven metal screen, that must be stated.Figure 1 Test apparatus >REFERENCE TO A GRAPHIC>Appendix 2 Information document in respect of a fuel tank type for a two or three-wheel motor vehicle >START OF GRAPHIC>(to be attached to the component type-approval application where this is submitted separately from the whole vehicle type-approval application)Order No (assigned by the applicant): ..........The component type-approval application in respect of a fuel tank type must contain the information set out in Annex II to Directive 92/61/EEC of 30. 6. 1992, under A, in sections:0.1 (¹),0.2 (¹),0.5 to 0.6 (²),3.2.2 to 3.2.3.2.(¹) i.e.: of the fuel tank.(²) i.e.: of the fuel tank manufacturer.

GENERAL1.1. Measuring equipmentThe measuring equipment must meet the conditions laid down in Publication No 16, Edition 2, of the International Special Committee on Radio Interference (CISPR).A quasi-peak detector must be used to measure wide-band electromagnetic radiation.1.2. Test methodThe test is designed to measure wide-band radiation from spark ignition systems and electric motors within systems designed for continuous use (e.g., electric traction motors, heating system/demister motors and fuel pumps).As regards the choice of reference antenna, that choice being determined by common agreement between manufacturers and testing bodies: the distance in the vehicle may be either 10 or 3 metres. In both cases, the conditions set out in section 3 below must be complied with.2. EXPRESSION OF RESULTSThe measured results are expressed in dB (microvolts/m) for bandwidths of 120 kHz. If the measuring equipment's actual bandwidth B (expressed in kHz) does not correspond exactly to 120 kHz, readings must be converted to a bandwidth of 120 kHz by adding 20 log (120/B), where B must be less than 120 kHz.3. TEST CONDITIONS3.1. The test surface must be horizontal and untrammelled and free of electromagnetic reflective surfaces within a minimum radius of 30 m, measured from a point mid-way between the vehicle and the antenna (see fig. 1 in Appendix 1). Alternatively, the test surface may be any location that fulfils the conditions shown in fig. 2 in Appendix 1.3.2. Both the measuring equipment and the test cab or the vehicle in which the measuring equipment is situated are positioned within the part of the test surface shown in fig. 1 in Appendix 1. Where the test surface fulfils the conditions stated in fig. 2 in Appendix 1, the measuring equipment must lie outside the part shown in fig. 2.3.3. Closed installations may be used for the tests, if it is to be demonstrated that a correlation exists between these installations and the external test surface.Such installations are not subject to the dimensional conditions specified in figs 1 and 2 of Appendix 1, except for the condition relating to the distance between the vehicle and the antenna and to the height of the latter.3.4. In order to ensure the absence of any noise or extraneous signals of a level that might materially affect the measurements, such measurements must be taken before and after the main test. If the vehicle is present during these measurements, steps must be taken to ensure that no emission from the vehicle can significantly affect the measurements (e.g., the ignition key should be removed or the battery disconnected when the vehicle is withdrawn from the test surface). For both types of measurement, the noise or extraneous signal must be at least 10 dB below the limits stated in Annex I (5.2.2.1 or 5.2.2.2, as the case may be), save for intentional narrow-band ambient emissions.4. STATE OF THE VEHICLE DURING THE TEST4.1. EngineThe engine must function at its normal operating temperature and, where a gearbox is fitted, must be in neutral. If this is not possible for practical reasons, alternative solutions must be sought by agreement with the manufacturer and the authorities responsible for carrying out the tests. Steps must be taken to ensure that the gear-changing mechanisms do not exert any influence on electromagnetic radiation from the vehicle. During each measurement, the engine must operate as follows:>TABLE>4.2. Equipment controlled by the driverThe equipment controlled by the driver (including such components as heating-fan and air-conditioning motors and excluding other components such as seat or windscreen-wiper motors) is designed for steady-state operation cycle at 100 % and must operate in such a way as to absorb the maximum current.4.3. Test must not be carried out in the rain, nor must they be carried out for 10 minutes after it has stopped raining.4.4. The driver must occupy the driving position assigned to him if, in the judgment of the testing body, this represents the worst-case scenario.5. ANTENNA TYPE, POSITION AND ORIENTATION5.1. Antenna typeAny type of linearly polarized antenna is permitted, provided that it can be standardized on the reference antenna.5.2. Measurement height and distance5.2.1. Height5.2.1.1. Tests at 10 mThe antenna phase mid-point must be 3,0 ± 0,05 m above the vehicle plane.5.2.1.2. Tests at 3 mThe antenna phase mid-point must be 1,8 ± 0,05 m above the vehicle plane.5.2.1.3. No part of the antenna receiving components must be less than 0,25 m from the vehicle plane.5.2.2. Measuring distance5.2.2.1. Tests at 10 mThe horizontal distance from the antenna phase mid-point to the external surface of the vehicle must be 10,0 ± 0,2 m.5.2.2.2. Tests at 3 mThe horizontal distance from the antenna phase mid-point to the external surface of the vehicle must be 3,0 ± 0,05 m.5.2.2.3. If the test is carried out in a closed installation with the object of creating an electromagnetic screen against radiofrequencies, the position of the antenna receiving components must not be less than (0,5) m from any type of radiofrequency absorption material of less than (1,5) m from the closed installation. There must be no absorption material between the receiving antenna and the vehicle under test.5.3. Position of the antenna in relation to the vehicleThe antenna must be positioned successively on each side of the vehicle parallel to the longitudinal median plane of the vehicle and in line with the mid-point of the engine (see fig. 3 in Appendix 1).5.4. Position of the antennaReadings are taken for each measuring point, first with the antenna vertically polarized and then horizontally polarized (see fig. 3 in Appendix 1).5.5. MeasurementsThe maximum value of the four measurements taken in accordance with 5.3 and 5.4 for each frequency is regarded as the characteristic measurement for this frequency.6. FREQUENCIES6.1. MeasurementMeasurements are taken over a range of frequencies from 30 to 1 000 MHz. A vehicle is deemed to comply with the requisite limits over the entire frequency range if it meets the limits laid down for the following 11 frequencies: 45, 65, 90, 150, 180, 220, 300, 450, 600, 750 and 900 MHz. Should the limit be exceeded during the tests, steps must be taken to confirm that this is due to the vehicle and not to ambient radiation.6.2. Tolerances>TABLE>The tolerances are applied to the above frequencies with the aim of avoiding interference in transmissions operating at, or close to, the nominal frequencies during the measurements.Appendix 1 Figure 1 Vehicle test surface >REFERENCE TO A GRAPHIC>Figure 2 Vehicle test surface >REFERENCE TO A GRAPHIC>Figure 3 Position of antenna in relation to vehicle >REFERENCE TO A GRAPHIC>ANNEX III METHOD OF MEASURING NARROW-BAND ELECTROMAGNETIC RADIATION FROM VEHICLES 1. GENERAL1.1. Measuring equipmentThe measuring equipment must comply with the conditions laid down in Publication No 16, Edition 2, of the International Special Committee on Radio Interference (CISPR).A mean-value detector is used to measure narrow-band electromagnetic radiation.1.2. Test methodThe test is designed to measure narrow-band electromagnetic radiation such as that which may be generated by a microprocessor-based system or from another narrow band source.As regards the choice of antenna, that choice being determined by common agreement between manufacturer and testing body, the distance from the vehicle may be either 10 or 3 metres. In both cases, the conditions set out in section 3 below must be complied with. In the initial stage (2-3 minutes) it is possible, through the choice of antenna position and polarization, to scan the range of frequencies listed in 6.1 by the use of a spectrum analyzer or an automatic receiver to indicate the maximum transmitting frequencies. This can be useful for selecting the frequencies to be tested in each band (see section 6).2. EXPRESSION OF THE RESULTSThe measured results are expressed in dB (microvolts/m).3. TEST CONDITIONS3.1. The test surface must be horizontal and untrammelled and free of electromagnetic reflections within a minimum radius of 30 m, measured from a point mid-way between the vehicle and the antenna (see fig. 1 in Appendix 1, Annex II). Alternatively, the test surface may be any location that fulfils the conditions shown in fig. 2 in Appendix 1, Annex II.3.2. Both the measuring equipment and the test cab or the vehicle in which the measuring equipment is situated are positioned within the test surface, but only in the part shown in fig. 1 in Appendix 1, Annex II. Where the test surface fulfils all the conditions set out in fig. 2 in Appendix 1, Annex II, the measuring equipment must lie outside the part shown in that figure.3.3. Closed installations may be used for the tests, provided that it can be demonstrated that a correlation exists between these installations and the external test surface. Such installations are not subject to the dimensional conditions laid down in figs 1 and 2 in Appendix 1, Annex II, except as regards the distance between the vehicle and the antenna and to the height of the latter.3.4. In order to ensure the absence of any noise or extraneous signals of a level that might materially affect the measurements, such measurements must be taken before and after the main test. Steps must be taken to ensure that no emission from the vehicle can significantly affect the measurements (e.g., the ignition key should be removed or the battery/batteries disconnected when the vehicle is withdrawn from the test surface). For both types of measurement, the noise or extraneous signal must be at least 10 dB below the interference limits contained in Annex I (5.3.2.1 or. 5.3.2.2, depending on the distance between the vehicle and the antenna), save for intentional narrow-band ambient emissions.4. STATE OF THE VEHICLE DURING THE TESTS4.1. The vehicle's electronic systems must be in their normal operating mode and the vehicle must be stationary.4.2. The ignition must be connected. The engine must not be running.4.3. Tests must not be carried out in the rain, nor must they be carried out for 10 minutes after it has stopped raining.5. ANTENNA TYPE, POSITION AND ORIENTATION5.1. Antenna typeAny type of linearly polarized antenna is permitted, provided that it can be standardized with the reference antenna.5.2. Measurement height and distance5.2.1. Height5.2.1.1. Tests at 10 mThe antenna phase mid-point must be 3,0 ± 0,05 m above the vehicle plane.5.2.1.2. Tests at 3 mThe antenna phase mid-point must be 1,8 ± 0,05 m above the vehicle plane.5.2.1.3. No part of the antenna's receiving components may be less than 0,25 m from the vehicle plane.5.2.2. Measuring distance5.2.2.1. Test at 10 mThe horizontal distance from the antenna phase mid-point to the external surface of the vehicle must be 10,0 ± 0,2 m.5.2.2.2. Test at 3 mThe horizontal distance from the antenna phase mid-point to the external surface of the vehicle must be 3,00 ± 0,05 m.5.2.2.3. If the test is carried out in a closed installation with the object of creating an electromagnetic screen against radio frequencies, the position of the antenna receiving components must not be less than (0,5) m from any type of radiofrequency absorption material or less than (1,5) m from the wall of the installation in question. There must be no absorption material between the receiving antenna and the vehicle under test.5.3. Position of the antenna in relation to the vehicleThe antenna must be positioned successively on each side of the vehicle parallel to the median longitudinal plane of the vehicle and in line with the mid-point of the engine (see figs 1, 2 and 3, Appendix 1, Annex II).5.4. Position of the antennaReadings are taken for each measuring point, with the antenna both vertically and horizontally polarized (see fig. 3, Appendix 1, Annex II).5.5. MeasurementsThe maximum values of the four measurements taken for each frequency in accordance with 5.3 and 5.4 are regarded as the characteristic measurement for this frequency.6. FREQUENCIES6.1. MeasurementsMeasurements are taken over a range of frequencies from 30 to 1 000 MHz. This range is divided into 11 bands. In each band a test is carried out on the frequency with the highest value in order to check that it is within the required limits. A vehicle is deemed to comply with the requisite limits over the entire frequency range if it meets with the selected frequency in each of the following 11 frequency bands: 30-45, 45-80, 80-130, 130-170, 170-225, 225-300, 300-400, 400-525, 525-700, 700-850 and 850-1 000 MHz.6.2. If, during the first test carried out in accordance with the test method described in 1.2, the narrow-band radiation for any of the bands defined in 6.1 are at least 10 dB below the reference limit, then the vehicle is deemed to fulfil the conditions laid down in this Annex for the frequency band under consideration. In that case, the full test is not necessary.ANNEX IV METHODS OF TESTING VEHICLE IMMUNITY TO ELECTROMAGNETIC RADIATION 1. GENERAL1.1. Test methodsThese tests are designed to demonstrate the insensitivity of the vehicle to any factor which may alter the quality of its direct control. The vehicle must be exposed to the electromagnetic fields, described in this Annex, and must be monitored during the tests.2. EXPRESSION OF THE RESULTSThe field strengths must be expressed in volts/m for all the tests described in this Annex.3. TEST CONDITIONSThe test equipment must be capable of generating the field strengths in the range of frequencies defined in this Annex, and must meet the (national) legal requirements regarding electromagnetic signal. The control and monitoring equipment must not be susceptible to radiation fields whereby the tests could be invalidated.4. STATE OF THE VEHICLE DURING THE TESTS4.1. The mass of the vehicle must be equal to the mass in running order.4.1.1. The engine must turn the driving wheels at a constant speed predetermined by the testing authority in agreement with the vehicle manufacturer. The vehicle must be placed on a suitably loaded dynamometer or, if no dynamometer is available, must rest on electronically insulated axle supports at a minimum distance from the ground.4.1.2. The dipped-beam headlamps must be switched on.4.1.3. The left or right direction indicators must be on.4.1.4. All other vehicle systems must be operating normally.4.1.5. There must be no electrical connection between the vehicle and the test surface and no connections between the vehicle and the equipment, save where so required by 4.1.1 or 4.2. Contact between the wheels and the test surface is not regarded as an electrical connection.4.2. Where STUs are involved in the direct control of the vehicle and where these systems do not operate under the conditions described in 4.1.1, the testing authority may carry out separate tests on the systems in question under conditions agreed with the vehicle manufacturer.4.3. During the tests on the vehicle, only non-interference-generating equipment may be used (see section 8).4.4. Under normal conditions, the vehicle must be facing the antenna.5. TYPE, POSITION AND ORIENTATION OF THE FIELD GENERATOR5.1. Type of field generator5.1.1. The criterion for the selection of the field generator type is the capacity of the latter to attain the prescribed field strength at the reference point (see 5.4) and at the appropriate frequencies.5.1.2. Either the antenna(s) or a transmission line system (TLS) may be used as the field-generating device(s).5.1.3. The design and orientation of the field generator must be such that the field is polarized both horizontally and vertically at frequencies between 20 and 1 000 MHz.5.2. Measurement height and distance5.2.1. Height5.2.1.1. The phase mid-point of all antennas must not be less than 1,5 m above the vehicle plane.5.2.1.2. No part of the antenna radiator elements must be less than 0,25 m from the vehicle plane.5.2.2. Measuring distance5.2.2.1. Greater homogeneity of the field may be obtained by placing the field generator as far as technically possible from the vehicle. This distance will normally be in the range 1 to 5 m.5.2.2.2. If the test is carried out in a closed installation, the radiator elements of the field generator must not be less than 0,5 m from any type of radiofrequency absorption material and not less than 1,5 m from the wall of the installation in question. There must be no absorption material between the transmitting antenna and the vehicle under test.5.3. Position of the antenna in relation to the vehicle5.3.1. The field generator must be positioned in the median longitudinal plane of the vehicle.5.3.2. No part of the TLS, except the vehicle plane, may be less than 0,5 m from any part of the vehicle.5.3.3. Any field generator placed above the vehicle must cover at least 75 % of the length of the vehicle.5.4. Reference point5.4.1. The reference point is the point at which the field strengths are established and is defined as follows:5.4.1.1. horizontally, at least two metres from the antenna phase mid-point or, vertically, at least one metre from the TLS radiator elements;5.4.1.2. in the median longitudinal plane of the vehicle;5.4.1.3. at a height of 1,0 ± 0,05 m above the vehicle plane;5.4.1.4. or:at 1,0 ± 0,2 m behind the vertical centre line of the vehicle's front wheel (point C in Appendix 1) in the case of tricyclesor:at 0,2 ± 0,2 m behind the vertical centre line of the vehicle's front wheel (point D in Appendix 2) in the case of motorcycles.5.5. If the testing authority chooses to subject the rear part of the vehicle to radiation, the reference point must be established as stated in 5.4. In this case the vehicle will be positioned with its front part facing in the opposite direction to the antenna and as if it had been rotated horizontally through 180 degrees about its central point. The distance between the antenna and the nearest part of the outer surface of the vehicle must remain the same (see Appendix 3).6. REQUISITE TEST CONDITIONS6.1. Range of frequencies, duration of the tests, polarizationThe vehicle must be exposed to electromagnetic radiation in the 20-1 000 MHz frequency range.6.1.1. The tests are to be carried out at the following 12 frequencies: 27, 45, 65, 90, 150, 180, 220, 300, 450, 600, 750 and 900 MHz ± 10 % for 2 s at ± 10 % in each frequency.6.1.2. One of the polarization modes described in 5.1.3 must be selected by common agreement between manufacturer and testing body.6.1.3. All other test parameters are as defined in this Annex.6.2. Tests to check deterioration in direct control6.2.1. A vehicle is deemed to fulfil the requisite immunity conditions if, during the tests carried out in the manner required by this Annex, there are no abnormal changes in the speed of the vehicle's drive wheels, there are no signs of operational deterioration which might mislead other road users and there are no other noticeable phenomena which could result in a deterioration in the direct control of the vehicle.6.2.2. For vehicle observation purposes, only the monitoring equipment described in section 8 may be used.6.2.3. If a vehicle does not meet the requirements of the tests defined in 6.2, steps must be taken to verify that the faults occurred under normal conditions and are not attributable to spurious fields.7. GENERATION OF THE REQUISITE FIELD STRENGTH7.1. Test method7.1.1. The 'substitution method` is to be used for the purpose of creating the field test conditions.7.1.2. Substitution methodFor each test frequency required, the RF power level of the field generator must be set so as to produce the required test field strength at the reference point of the test area without the vehicle being present. This RF power level, as well as all other relevant settings on the field generator must be recorded in the test report (calibration curve). The recorded information is to be used for type-approval purposes. Should any alterations be made to the equipment at the test location, the substitution method must be repeated.7.1.3. The vehicle is then brought to the test installation and positioned in accordance with the conditions laid down in section 5. The power required by 7.1.2 is then applied to the field generator for each of the frequencies indicated in 6.1.1.7.1.4. Whatever field-definition parameter in chosen in accordance with the conditions laid down in 7.1.2, the same parameter must be used in order to determine the strength of that field throughout the test.7.1.5. For the purposes of this test, the same field generating equipment and the same equipment configuration must be used as in the operations conducted in pursuance of 7.1.2.7.1.6. Field strength measuring deviceUnder the substitution method, the device used to determine the field strength during the calibration stage should take the form either of a compact isotropic probe for measuring field strength or of a calibrated receiving antenna.7.1.7. During the calibration phase of the substitution method, the phase mid-point of the field-strength measuring device must coincide with the reference point.7.1.8. If a calibrated receiving antenna is used as the field strength measuring device, readings will be obtained in three directions at right angles to each other. The equivalent isotropic value corresponding to these measurements is to be regarded as the field strength.7.1.9. In order to take account of differences in vehicle geometry, a number of reference points must be established for the relevant test installation.7.2. Field strength contour7.2.1. During the calibration phase (before the vehicle is positioned on the test surface) the field strength must not be less than 50 % of the nominal field strength at the following locations:(i) for all field-generating devices, 1,0 ± 0,02 m on either side of the reference point on a line passing through this point, and perpendicular to the median longitudinal plane of the vehicle;(ii) in the case of a TLS, 1,5 ± 0,02 m on a line passing through the reference point, and situated in the median longitudinal plane of the vehicle.7.3. Characteristics of the test signal to be generated7.3.1. Peak value of the modulated test field strengthThe peak value of the modulated test field strength must correspond to that of the unmodulated test field strength, the actual value in volts/m of which is defined in section 5.4.2 of Annex I.7.3.2. Test signal waveformThe test signal must be a radio-frequency sinusoidal wave, amplitude-modulated by a sinusoidal 1 kHz wave at a modulation rate m of 0,8 ± 0,04 m.7.3.3. Modulation rateThe modulation rate m is defined as follows:m =  >NUM>peak envelope value - minimum envelope value >DEN>peak envelope value + minimum envelope valueThe envelope describes the curve formed by the edges of the modulated carrier as seen on an oscillograph.8. INSPECTION AND MONITORING EQUIPMENT8.1. For the purposes of monitoring the external part of the vehicle and the passenger compartment and of determining whether the conditions laid down in 6.2 have been met, use will be made of a video camera or cameras.Appendix 1 >REFERENCE TO A GRAPHIC>Appendix 2 >REFERENCE TO A GRAPHIC>Appendix 3 >REFERENCE TO A GRAPHIC>ANNEX V METHOD OF MEASURING WIDE-BAND ELECTROMAGNETIC RADIATION FROM SEPARATE TECHNICAL UNITS (STU) 1. GENERAL1.1. Measuring equipmentThe measuring equipment must meet the conditions laid down in Publication No 16, Edition 2, of the International Special Committee on Radio Interference (CISPR).A quasi-peak detector must be used to measure wide-band electromagnetic emissions.1.2. Test methodThis test is designed to measure wide-band emissions generated by spark-ignition systems or by electric motors fitted to systems designed for continuous use (e.g. electric traction motor, heating system/demister motors, fuel pumps etc.)2. EXPRESSION OF RESULTSThe measured results are expressed in dB (microvolts/m) for a bandwidth of 120 kHz. If the measuring equipment's actual bandwidth B (expressed in kHz) does not correspond exactly to 120 kHz, readings must be converted to a bandwidth of 120 kHz by adding 20 log (120/B), where B must be less than 120 kHz.3. TEST CONDITIONS3.1. The testing surface must meet the conditions laid down in publication No 16, Edition 2, of the International Special Committee en Radio Interference (CISPR). (See fig. 1 in Appendix 1 to this Annex.)3.2. The measuring equipment and the test cab or the vehicle in which the measuring equipment is situated must be positioned outside the area shown in fig. 1, Appendix 1 to this Annex.3.3. Covered equipment may be used for the tests if it is demonstrated that there is a correlation between the results obtained therewith and those obtained by using an outside surface which has been approved for the tests. Covered test equipment has the advantage of enabling tests to be conducted in all weathers, within a controlled environment and with improved measurement repeatability deriving from more stable electrical characteristics. This covered facility does not need to meet the dimensional requirements set out in figure 1, in Appendix 1 to this Annex, apart from those relating to the distance between the antenna and the STU and to the height of the antenna.3.4. In order to ensure that there is no extraneous noise or signal of such a magnitude that they could materially affect the measurements, the background radiation is measured before and after the main test. For both of these measurements both the noises and extraneous signals must be at least 10 dB below the limits set out in section 5.5.2.1 in Annex I, except in the case of deliberate narrow-band transmissions within the environment.4. STATE OF THE STU DURING THE TEST4.1. The STU must be in its normal operating state.4.2. Measurements must not be carried out in the rain, nor for 10 minutes after the rain has stopped.4.3. The STU and its cable harnesses must be placed on insulated supports 50 + 10/- 0 mm above the earth plate. However, if one of the parts of the STU was intended to be electrically connected to the metal bodywork of the vehicle, that part must be situated on the earth plate and connected thereto electrically.The earth plate must be a metal sheet at least 0,25 mm thick. The minimum dimensions of the earth plate depends upon the size of the STU but will have to be sufficiently large to receive the cable harness and the components of the vehicle system. The earth plate must be connected to the earth conductor, located 1,0 ± 0,1 m above the ground and run parallel thereto.The STU must be ready to operate and be connected in accordance with the conditions laid down. The power distribution cable harness must run parallel to the edges of the earth plate and be no more than 100 mm form the edge of the plate closest to the antenna.The STU must be earthed in accordance with the manufacturer's specifications: no additional earth connections are permitted.The minimum distance between the STU and all of the other conducting structures such as the walls of a protected area (except, however, for the base plate below the test piece) must be at least 1,0 m.4.4. Power for the STU is supplied by a 50ìH Line Impedance Stabilizing Network (LISN) which is connected electrically to the earth plate. The power supply voltage must be maintained at ± 10 % of the nominal operating voltage of the system. All ripple voltage must be less than 1,5 % of the nominal operating voltage of the system measured at the LISN monitoring port.4.5. If the STU consists of more than one component the best way of linking them is to use the cable harness intended for use on the vehicle. The cable harness used should as far as possible duplicate that used in practice and preferably be connected to the actual loads and actuators. If other equipment not to be included in the measurement is needed for the functioning of the unit in accordance with the regulations, the proportion of radiation emissions measured in the overall measurement must be taken into account.5. ANTENNA TYPE, POSITION AND ORIENTATION5.1. Antenna typeAny type of linearly polarized antenna is permitted provided that it can be standardized on the reference antenna.5.2. Measurement height and distance5.2.1. HeightThe phase centre of the antenna must be 0,5 ± 0,05 m above the earth plate.5.2.2. Measuring distanceThe horizontal distance measured between the antenna phase mid-point and the edge of the earth plate must be 1,0 ± 0,05 m. No part of the antenna may be less than 0,5 m from the earth plate.The antenna must be placed parallel to the plane perpendicular to the earth plate and run along that edge of the plate along which the main parts of the cable harness are situated.5.2.3. If the test is carried out in a closed installation with the object of creating an electromagnetic screen against radio frequencies, the antenna receiving components must not be less than 0,5 m from any type of radio frequency absorption material or less than 1,5 m from the wall of the closed installation. There must be no absorption material between the receiving antenna and the STU for the vehicle under test.5.3. Orientation and polarization of the antennaReadings must be taken at the measuring point with the antenna polarized, first horizontally and then vertically.5.4. MeasurementsThe greater of the two measurements taken in accordance with 5.3 for each single frequency must be regarded as the characteristic measurement for that frequency.6. FREQUENCIES6.1. MeasurementsThe measurements are to be taken over a range of frequencies from 30 to 1 000 MHz. An STU is deemed to fall within the limits for the full range of frequencies if it does not exceed the limits laid down for the following 11 frequencies: 45, 65, 90, 150, 180, 220, 300, 450, 600, 750 and 900 MHz. Should the limit be exceeded, steps must be taken to confirm that this is due to the STU and not to ambient radiation.6.2. Tolerances>TABLE>The aim of the tolerances applying to the frequencies set out above is to avoid interference in transmissions operating at, or close to, the nominal frequencies during the measurements.Appendix 1 Figure 1 Boundaries of the testing surface >REFERENCE TO A GRAPHIC>ANNEX VI METHOD OF MEASURING NARROW-BAND ELECTROMAGNETIC RADIATION FROM SEPARATE TECHNICAL UNITS (STUs) 1. GENERAL1.1. Measuring equipmentThe measuring equipment must meet the conditions laid down in publication No 16, edition 2 by the International Special Committee on Radio Interference (CISPR).A mean-value detector is used to measure the narrow-band electromagnetic radiation.1.2. Test methodThe test is designed to measure narrow-band electromagnetic radiation such as that which may emanate from a micro-processor based system. In the initial stage (2-3 minutes) it is permissible, once an antenna polarization has been selected, to scan the range of frequencies identified in 6.1 by using a spectrum analyzer to pinpoint the maximum transmission frequencies. This can make it easier to select the frequencies to be tested (see section 6).2. EXPRESSION OF RESULTSThe results of the measurements are to be expressed in dB (microvolts/m).3. TEST CONDITIONS3.1. The test surface must meet the conditions laid down in publication No 16, edition 2, of the International Special Committee on Radio Interference (CISPR) (see figure 1 in Appendix 1 to Annex V).3.2. The measuring equipment, the test cab, or the vehicle in which the measuring equipment is situated must be outside the area of the test-surface indicated in fig. 1 in Appendix 1 to Annex V.3.3. Closed installations may be used for the tests, provided that it can be demonstrated that a correlation exists between these installations and the external test surface. These test installations have the advantage that all of the measuring equipment is at all times operating in a controlled environment and its repeatability is improved as a result of its more stable electrical characteristics. The closed testing installations are not subject to the dimensional requirements laid down in figure 1 in Appendix 1 to Annex V, except for those relating to the distance between the STU and the antenna and to the height of the antenna.3.4. In order to ensure the absence of any noise or extraneous signals of a level that might affect the measurements materially, the background radiation must be measured before and after the main test. For both types of measurement, the noise or extraneous signals must be at least 10 dB below the value given in section 5.6.2.1 of Annex I, save for intentional narrow-band emissions.4. STATE OF THE STU DURING THE TESTS4.1. The STU must be in its normal operating state.4.2. No measurements may be taken while it is raining on the STU nor for ten minutes after it has stopped raining.4.3. The STU and its cable harnesses must be placed on insulated supports 50 + 10/- 0 mm above the earth plate. However, if one of the parts of the STU is intended to be connected electrically to the metal bodywork of the vehicle that part must be located on and be connected electrically to the earth plate.The earth plate must be in the form of a metal sheet at least 0,25 mm thick. The minimum size of the earth plate depends upon the size of the STU, but must be sufficiently large to carry the vehicle system's components and cable harnesses. The earth plate must be connected to the earth-conductor, must be located at a height of 1,0 ± 0,1 m above the ground and be parallel to it.The STU must be ready to operate and connected in accordance with the instructions. The power distribution cables must run parallel to and lie at the most 100 mm from the edge of the earth plate closest to the antenna.The STU must be earthed as specified by the manufacturer: no additional earth connections are permitted.The distance between the STU and the other conducting structures, such as the walls of a shielded area (except for the earth plate supporting the test object) must be at least 1,0 m.4.4. Power is applied to the STU via a 50 ìH Line Impedance Stabilizing Network (LISN), which is connected electrically to the earth plate. The electrical supply voltage must remain within ± 10 % of the nominal operating voltage of the system. Any ripple voltage must be less than 1,5 % of the nominal operating voltage of the system measured at the LISN monitoring port.4.5. If the STU consists of more than one component the best way of linking them together is to use the cable harness intended for use on the vehicle. The cable harness used must as far as possible duplicate that used in practice and preferably be connected to the actual loads and actuators. If other equipment not to be included in the measurement is needed for the functioning of the unit in accordance with the regulations, the proportion of radiation emissions measured in the overall measurement must be taken into account.5. ANTENNA TYPE, POSITION AND ORIENTATION5.1. Antenna typeAny type of linearly polarized antenna is permitted, provided that it can be standardized with the reference antenna.5.2. Measurement height and distance5.2.1. HeightThe phase centre of the antenna must be 0,50 ± 0,05 m above the earth plate.5.2.2. Measuring distanceThe horizontal distance measured between the antenna phase mid-point and the earth plate must be 1,00 ± 0,05 m. No part of the antenna may be less than 0,5 m from the earth plate.The antenna must lie parallel to a plane that is perpendicular to the earth plate and run along that edge of the plate along which the main parts of the harness are situated.5.2.3. If the test is carried out in a closed installation with the object of creating a screen against radiofrequencies, the antenna's receiving components must not be less than 0,5 m from any type of radiofrequency absorption material or less than 1,5 m from the wall of the screen in question. There may be no absorption material between the receiving antenna and the vehicle under test.5.3. Orientation and polarization of antennaReadings are to be taken at the measuring point, with the antenna polarized, first horizontally and then vertically.5.4. MeasurementsThe greater of the two measurements taken in accordance with 5.3 for each frequency must be regarded as the characteristic measurement for that frequency.6. FREQUENCIES6.1. MeasurementsMeasurements are taken over a range of frequencies from 30 to 1 000 MHz. This range is divided into 11 bands. In each band a test is carried out on the frequency with the highest value, in order to check that it is within the required limits. A vehicle is deemed to comply with the requisite limits over the entire frequency range if it meets the limits laid down for the selected frequency in each of the following 11 frequency bands: 30-45, 45-80, 80-130, 130-170, 170-225, 225-300, 300-400, 400-525, 525-700, 700-850, 850-1 000 MHz.6.2. If, during the first measurement conducted in accordance with 1.2, the narrow-band radiation emissions for any of the bands referred to in 6.1 are at least 10 dB below the reference limit, then the STU is deemed to meet the conditions laid down in this Annex for the frequency band under consideration. In that case, the full test is not necessary.ANNEX VII METHODS OF TESTING STU IMMUNITY TO ELECTROMAGNETIC RADIATION 1. GENERAL1.1. Test methodsSTUs must comply with the limits (see Annex I, section 5.7.2.1) for one of the following test methods, at their manufacturers discretion, within the range of 20-1 000 MHz:- 150 mm stripline test: see figure 1 in Appendix 1;- 800 mm stripline test: see figures 2 and 3 in Appendix 1;- Bulk current injection test: see figures 1 and 2 in Appendix 2;- TEM-cell test: see figure 1 in Appendix 3;- free-field STU immunity test: see figure 1 in Appendix 4.NB: To avoid radiation from electromagnetic fields during tests, they must be carried out in a shielded area.2. EXPRESSION OF THE RESULTSFor all of the tests described in this Annex, the field strengths must be expressed in volts/m and the injected current in milliamperes.3. TEST CONDITIONS3.1. The test equipment must be capable of generating the test signal required for the frequency ranges defined in this Annex. The location of the tests must meet the (national) legal requirements regarding electromagnetic signal emissions.3.2. The control and monitoring equipment may not be affected by any radiation fields which could invalidate the tests.4. STATE OF THE STU DURING THE TEST4.1. The STU must be in its normal operating state. It must be arranged as shown in this Annex unless otherwise required by a specific individual test method.4.2. The STU and its cable harnesses must be placed on insulated supports 50 ± 10/- 0 mm above the earth plate. However, if one of the parts of the STU is intended to be connected electrically to the metal bodywork of the vehicle that part must be placed on the earth plate and connected to it electrically.The earth plate must be in the form of a metal sheet that is at least 0,25 mm thick, except where a TEM-cell test is used. The minimum size of the earth plate depends on the size of the STU, but must be large enough to carry the STUs components and harnesses. The earth plate must be connected to an earth conductor, must be 1,0 ± 0,1 m above the ground and parallel to it.There must be a distance of at least 1,0 m between the STU and all the other conducting structures such as the walls of a shielded area (except the earth plate underneath the test piece), save where a TEM-cell test is used.4.3. Power is applied to the STU via a 50 ìH Line Impedance Stabilizing Network (LISN) which is connected electrically to the earth plate. The supply voltage must be kept at a constant level. Any deviation in the constant supply voltage from the STU's nominal operating voltage must be no more than ± 10 % of the STU's nominal operating voltage. Any ripple in the power supply voltage measured at the monitoring port of the power supply must not exceed 1,5 % of the STU's nominal operating voltage.4.4. Any extraneous equipment needed to operate the STU must be in place during the calibration stage. During the calibration, it must be placed at least 1 m from the reference point.4.5. In order to obtain reproducible results the tests and measurements will be repeated. The test-signal generating equipment and its configuration must be to the same specification as that used during each of the appropriate calibration phases (sections 7.2, 8.2 and 10.3 of this Annex).5. MEASURING FREQUENCIES, DURATION OF TESTS5.1. Measurements will be conducted within the frequency range of 20-1 000 MHz.5.2. The tests are to be carried out with the following 12 frequencies: 27 MHz, 45 MHz, 65 MHz, 90 MHz, 150 MHz, 180 MHz, 220 MHz, 300 MHz, 450 MHz, 600 MHz, 750 MHz, 900 MHz ± 10 % for two s ± 10 % in each frequency.6. CHARACTERISTICS OF TEST SIGNAL TO BE GENERATED6.1. Peak value of modulated test fieldThe peak value of the modulated test field strength must correspond to that of the unmodulated test field strength, the actual value of which is defined in section 5.7.2 of Annex I.6.2. Test signal wave formThe test signal will be a radio frequency sine wave, amplitude modulated by a 1 kHz sinusoidal wave at a modulation depth, m, of 0,8 ± 0,04.6.3. Modulation factorThe modulation factor, m, is defined as follows:m =  >NUM>Peak envelope value - minimum envelope value >DEN>Peak envelope value + minimum envelope valueThe envelope describes the curve formed by the edges of the modulated carrier as seen on an oscillograph.7. STRIPLINE TEST7.1. Test methodThis test method consists in subjecting the cable harnesses connecting the components in an STU to specified field strengths.The test method enables homogeneous fields to be generated between an active conductor (the stripline), and an earth plate (the conducting surface of the mounting table), between which part of the cable harness may be inserted.7.2. Field strength measurement in the striplineFor each required test frequency, a level of RF power is fed into the stripline, initially without the STU, to produce the required test field strength in the test area. This RF power level and all other relevant settings on the RF power generator must be recorded in the test report (calibration curve).The recorded information is to be used for type-approval purposes. Should any alterations be made to the equipment at the test location, the calibration of the stripline must be repeated.7.3. Installation of the STU7.3.1. The STU's electronic controller(s) must be mounted on the earth plate but outside the stripline with one of its edges parallel to the active conductor of the stripline. It must be 200 ± 10 mm from a line on the earth plate directly below the edge of the active conductor.All the edges of the active conductor must be at least 200 mm from any peripheral measuring device.The STU's cable harness must run horizontally between the active conductor and the earth plate.7.3.1.1. The minimum length of the cable harness to be placed under the stripline, and which will also include the power-supply lines for the electronic control unit, must be 1,5 m unless the cable harness in the vehicle is shorter than 1,5 m. In that case, the length of the cable harness will be that of the longest harness used in the vehicle installation. Any harness branches occurring must run perpendicular to the longitudinal axis of the line.7.3.1.2. Alternatively, the fully extended length of the cable harness, including that of the longest branch, will be 1,5 m.8. ALTERNATIVE TEST USING 800 mm STRIPLINE8.1. Test methodThe stripline consists of two parallel metallic plates separated by 800 mm. Equipment under test is positioned centrally between the plates and subjected to an electromagnetic field (see figs 2 and 3 of Appendix 1 to this Annex).This method can test complete electronic systems including sensors and actuators as well as the controller and wiring loom. It is suitable for apparatus whose largest dimension is less than   of the plate separation.8.2. Positioning of striplineThe stripline must be housed in a screened room (to prevent external emissions) and positioned 2 m away from walls and any metallic enclosure to prevent electromagnetic reflections. RF absorber material may be used to damp these reflections. The stripline must be placed on non-conducting supports at least 0,4 m above the floor.8.3. Calibration of the striplineA field measuring probe is positioned within the central third of the longitudinal, vertical and transverse dimensions of the space between the parallel plates with the system under test absent. The associated measuring equipment must be sited outside the screened room.At each desired test frequency, a level of power is fed into the stripline to produce the required field strength at the antenna. This level of forward power, or another parameter directly related to the forward power required to define the field, is to be measured and the results recorded. These results will be used for type-approval tests unless changes occur in the facilities or equipment which necessitate this procedure being repeated.8.4. Installation of the STU under TestThe main control unit must be positioned within the central third of the longitudinal, vertical and transverse dimension of the space between the parallel plates. It must be supported on a stand made from non-conducting material.8.5. Main wiring loom and sensor/actuator cablesThe main wiring loom and any sensor/actuator cables must rise vertically from the control unit to the top ground plate (this helps to maximize coupling with the electromagnetic field). Then they follow the under side of the plate to one of its free edges where they loop over and follow the top of the ground plate as far as the connections to the stripline feed. The cables are then routed to the associated equipment which must be sited in an area outside the influence of the electromagnetic field e.g.: on the floor of the screened room 1 m longitudinally away from the stripline.9. BULK CURRENT INJECTION TEST9.1. Test methodThis is a method of conducting immunity tests by using a current injection probe to induce currents directly into a cable harness. This probe consists of a coupling clamp through which the STU cables pass. The immunity test can then be carried out by varying the frequency of the induced signals. The STU may be installed on an earth plate as described in 4.2 or in a vehicle in accordance with the vehicle design specification.9.2. Calibration of bulk current injection probeThe injection probe is attached to the calibration fixture shown in fig. 2 of Appendix 2 to this Annex, whereupon the test frequency range is swept in stages. The RF power input into the injection probe is increased for each test frequency until the current induced in the closed test circuit reaches the figure laid down in Annex I. The RF power level required for this must be recorded in the test report (calibration curve). Using this method, the requisite RF power of the field generator is applied to the test radio disturbance induced in a calibrated circuit. During the STU's radio disturbance immunity test, the frequency variable RF power, as determined during the calibration process, is then input for each frequency into the injection probe.9.3. Installation of the STUIf the system is mounted on the earth plate as described in 4.2 all of the cables in the cable harness must be finished as realistically as possible and preferably with real loads and actuators. For both vehicle-mounted and earth-plate mounted systems the current injection probe is wound in turn around all the wires in the cable harness at 100 ± 10 mm from each connector for the STU's electronic control units, instrumentation modules or active sensors, as illustrated in fig. 2 in Appendix 1.9.4. Power, signal and control wiresWhere an STU is mounted on an earth plate as described in 4.2, a cable harness will link a LISN with the main electronic control unit. This harness must run parallel to the edge of the earth plate, 100 mm ± 10 mm from its edge.This harness will contain the positive lead connecting the vehicle battery to this ECU and, if used on the vehicle, the negative lead wire.The distance from the ECU to the LISN will be 1,5 ± 0,1 m or may be the harness length between the ECU and the battery as used on the vehicle, if known, whichever is the shorter. If the vehicle harness is used, then any line branches along its length must be routed along the earth plate but perpendicular to its edge of axis. Otherwise the STU wires which are in this length must break out at the LISN.10. TEM-CELL TEST10.1. Test methodThe TEM (Transverse Electromagnetic Mode) cell generates homogeneous fields between the internal conductor (partition) and housing (earth plate). It is used for testing the STUs.10.2. Field strength measurement in a TEM cellThe field strength sensor is placed in the upper half of the TEM cell. In this part of the TEM cell the electronic control unit(s) has only a slight effect on the test field. The output of this sensor determines the field strength. Alternatively, the following equation may be used to determine the electrical field:E =  >NUM>&radic; (P × Z) >DEN>dE = electric field intensity (volts/m);P = cell-input power (W)Z = cell impedance (50 Ù)d = distance in metres between the upper wall and the plate (partition).10.3. Dimensions of TEM cellIn order to maintain a homogeneous field in the TEM cell and to obtain repeatable measurements, the height of the STU must not be more than   of the inside height of the cell.10.4. Power, signal and control wiresThe TEM cell is to be attached to a board equipped with a co-axial socket and a plug connector with an adequate number of pins. The power supply and signal leads running from the plug connector on the cell wall are directly connected to the testpiece.The external components such as sensors, power-supply units and control units are connected:(i) via a shielded peripheral;(ii) via the vehicle next to the TEM cell;(iii) directly to the shielded socketboard.Shielded cables must be used in connecting the TEM cell to the peripherals or the vehicle.11. 'FREE FIELD` TEST11.1. This method consists of testing STUs by exposing a complete STU to electromagnetic radiation.11.2. Type, position and orientation of the field generator11.2.1. Type of field generator11.2.1.1. Any field generator chosen must be able to achieve the desired field strength at the reference point at the appropriate frequencies.11.2.1.2. The field generating device may be one or more antenna(s) or a plate antenna.11.2.1.3. The design and orientation of the field generator must be such that the field is polarized both horizontally and vertically at frequencies between 20 and 1 000 MHz.11.2.2. Measuring height and distance11.2.2.1. Height11.2.2.1.1. The phase centre of the antenna may not be less than 0,5 m above the earth plate on which the STU is resting.11.2.2.1.2. No radiating part of the antenna may be closer than 0,25 m to the STU base plate base.11.2.2.2. Measuring distance11.2.2.2.1. Greater homogeneity of the field may be obtained by placing the field generator as far as technically possible from the STU. The distance will normally be between 1 and 5 m.11.2.2.2.2. If the test is carried out in an enclosed facility, the antenna's radiating components may be no closer than 0,5 m to any radio absorbent material and no closer than 1,5 m to the wall of the facility. There must be no absorbent material between the transmitting antenna and the STU.11.2.3. Position of the antenna in relation to the STU11.2.3.1. The field generator may not be closer than 0,5 m to the edge of the earth plate.11.2.3.2. The phase centre of the field generator must be on a plane which:(i) is perpendicular to the earth plate(ii) is perpendicular to the edge of the earth plate along which the main part of the cable harness runsand(iii) bisects the edge of the earth plate at the midpoint of the main part of the cable harness.The antenna is to be placed parallel to a plane which is perpendicular to and coincident with the edge of the earth plate along which the main part of the cable harness runs.11.2.3.3. Any field generator which is placed above the earth plate or the STU must completely cover the STU.11.2.4. Reference point11.2.4.1. The reference point is the point at which the field strength is measured. It is defined as follows:11.2.4.1.1. Horizontally at least 2 m from the antenna phase centre or, vertically, at least 1 m from the radiating components of a plate antenna.11.2.4.1.2. On a plane which:(i) is perpendicular to the earth plate;(ii) is perpendicular to the edge of the earth plate along which the main part of the cable harness runs;and(iii) bisects the edge of the earth plate and the midpoint of the main part of the cable harness.11.2.4.1.3. The reference point must be coincident with the midpoint of the main part of the harness which runs along the edge of the earth plate closest to the antenna and 100 ± 10 mm above the earth plate.11.3. Generation of required field strength11.3.1. Test method11.3.1.1. The 'substitution method` is to be used to ensure that the test field conditions are met.11.3.1.2. Substitution methodFor each required test frequency, the RF power level of the field generator must be set so as to produce the required test field strength at the reference point of the test area without the STU being present. This RF power level, as well as all other relevant settings on the field generator, must be recorded in the test report (calibration curve). The recorded information is to be used for type-approval purposes. Should any alterations be made to the equipment at the test location the substitution method must be repeated.11.3.1.3. The STU, which may include an additional earth plate, is then introduced into the test facility under the conditions set out in 11.2. If a second earth plate is used, it must be within 5 mm of the bench earth plate and be electrically connected to it. The required power, as defined in 11.3.1.2, is then applied to the field generator at each of the frequencies defined in section 5.11.3.1.4. Extraneous equipment must be at least 1 m from the reference point during calibration.11.3.1.5. Whatever parameter was chosen to produce the field in accordance with 11.3.1.2, the same is to be used to reproduce the desired field strength during the test.11.3.1.6. Field strength measuring deviceThe device used to determine the field strength during the calibration phase of the substitution method will be a compact isotropic field measuring probe.11.3.1.7. The phase centre of the field strength measuring device must be positioned at the reference point.11.3.2. Field strength contour11.3.2.1. During the calibration phase of the substitution method (before introduction of the STU into the test area), the field strength may not be less than 50 % of the nominal field strength 1,0 ± 0,05 m either side of the reference point on a line running through that point and parallel to the edge of the earth plate.Appendix 1 Figure 1 Stripline test >REFERENCE TO A GRAPHIC>Figure 2 800 mm Stripline test >REFERENCE TO A GRAPHIC>Figure 3 800 mm Stripline dimensions >REFERENCE TO A GRAPHIC>Appendix 2 Figure 1 Bulk current injection test >REFERENCE TO A GRAPHIC>Figure 2 Probe calibration circuit calibration set-up >REFERENCE TO A GRAPHIC>Appendix 3 Figure 1 TEM-cell test >REFERENCE TO A GRAPHIC>Appendix 4 Figure 1 Free-field test >REFERENCE TO A GRAPHIC>ANNEX VIII Appendix 1 Information document in respect of the electromagnetic compatibility of a type of two or three-wheel motor vehicle >START OF GRAPHIC>MODEL(To be attached to the application for component type-approval where this is submitted separately from the application for vehicle type-approval)Order No (assigned by the applicant): ..........The application for component type-approval in respect of the electromagnetic compatibility of a type of two or three-wheel motor vehicle must contain the information set out in Annex II to Directive No 92/61/EEC:Under A in sections:0.1, 0.2, 0.4 to 0.61.1 and 1.43.0 to 3.6, 3.1.24.1 and 4.2Under B in sections:1.1 to 1.1.5Under C in sections:2.1, 2.1.3, 2.1.4, 2.3 to 2.7.2, 2.8 to 2.8.2.4.Where appropriate, a brief description of the electrical and/or electronic components used in the transmission, suspension, braking, lighting, light-signalling and steering systems must also be supplied by the applicant for component type-approval.>END OF GRAPHIC>Appendix 2 Component type-approval certificate in respect of the electromagnetic compatibility of a type of two or three-wheel motor vehicle >START OF GRAPHIC>MODELName of administrationReport No: ..........by Technical Service: ..........Date: ..........Component type-approval No: ..........Extension No: ..........1.

DEFINITIONSFor the purposes of this Chapter:1.1. 'type of two-wheel moped as regards its sound level and exhaust system` means mopeds which do not differ in such essential respects as the following:1.1.1. type of engine (two or four-stroke, reciprocating piston engine or rotary-piston engine, number and capacity of cylinders, number and type of carburettors or injection systems, arrangement of valves, maximum net power and corresponding speed).The cubic capacity of rotary-piston engines is deemed to be double of the volume of the chamber;1.1.2. transmission system, in particular the number and ratios of the gears;1.1.3. number, type and arrangement of exhaust systems.1.2. 'exhaust system` or 'silencer` means a complete set of components necessary to limit the noise caused by a moped engine and its exhaust.1.2.1. 'original exhaust system or silencer` means a system of the type fitted to the vehicle at the time of type-approval or extension of type-approval. It may be the one first fitted or a replacement.1.2.2. 'non-original exhaust system or silencer` means a system of a type other than that fitted to the vehicle at the time of type-approval or extension of type-approval. It may be used only as a replacement exhaust system or silencer.1.3. 'exhaust systems of differing types` means systems which are fundamentally different in one of the following ways:1.3.1. systems comprising components bearing different factory or trade marks;1.3.2. systems comprising any component made of materials of different characteristics or comprising components which are of a different shape or size;1.3.3. systems in which the operating principles of at least one component are different;1.3.4. systems comprising components in different combinations.1.4. 'component of an exhaust system` means one of the individual components which together form the exhaust system (such as exhaust pipework, the silencer proper) and the intake system (air filter) if any.If the engine has to be equipped with an intake system (air filter and/or intake noise absorber) in order to comply with the maximum permissible sound levels, the filter and/or the absorber must be treated as components having the same importance as the exhaust system.2. COMPONENT TYPE-APPROVAL IN RESPECT OF THE SOUND LEVEL AND ORIGINAL EXHAUST SYSTEM, AS A SEPARATE TECHNICAL UNIT, OF A TYPE OF TWO-WHEEL MOPED2.1. Noise of the two-wheel moped in motion (measuring conditions and method for testing of the vehicle during component type-approval).2.1.1. Limits: see Annex I.2.1.2. Measuring instruments2.1.2.1. Acoustic measurementsThe apparatus used for measuring the sound-level must be a precision sound-level meter of the type described in International Electrotechnical Commission (IEC) publication 179 'Precision sound-level meters`, second edition. Measurements must be carried out using the 'fast` response and the 'A` weighting also described in that publication.At the beginning and end of each series of measurements the sound-level meter must be calibrated in accordance with the manufacturer's instructions, using an appropriate sound source (e.g. pistonphone).2.1.2.2. Speed measurementsEngine speed and moped speed on the test track must be determined to within ± 3 %.2.1.3. Conditions of measurement2.1.3.1. Condition of the mopedThe combined weight of the rider and the test equipment used on the moped must be no more than 90 kg and no less than 70 kg. If necessary, weights must be added to the moped to bring the combined weight up to at least 70 kg.During the measurements the moped must be in running order (including coolant, oils, fuel, tools, spare wheel and rider).Before the measurements are made the moped must be brought to the normal operating temperature.If the moped is fitted with fans with an automatic actuating mechanism, this system must not be interfered with during the sound measurements. For mopeds having more than one driven wheel, only the drive provided for normal road operation may be used. Where a moped is fitted with a sidecar, this must be removed for the purposes of the test.2.1.3.2. Test siteThe test site must consist of a central acceleration section surrounded by a substantially flat test area. The acceleration section must be flat; its surface must be dry and such that surface noise remains low.On the test site the variations in the free sound field between the sound source at the centre of the acceleration section and the microphone must not exceed 1 dB. This condition will be deemed to be met if there are no large objects which reflect sound, such as fences, rocks, bridges or buildings, within 50 m of the centre of the acceleration section. The road surface covering of the test track must conform to the requirements of Annex VII.The microphone must not be obstructed in any way which could affect the sound field, and no person may stand between the microphone and the sound source. The observer carrying out the measurements must so position himself as not to affect the readings of the measuring instrument.2.1.3.3. MiscellaneousMeasurements must not be made in poor atmospheric conditions. It must be ensured that the results are not affected by gusts of wind.For measurements, the A-weighted sound level of sound sources other than those of the vehicle to be tested and of wind effects must be at least 10 dB(A) below the sound level produced by the vehicle. A suitable windscreen may be fitted to the microphone provided that account is taken of its effect on the sensitivity and directional characteristics of the microphone.If the difference between the ambient noise and the measured noise is between 10 and 16 dB(A), in order to calculate the test results the appropriate correction must be subtracted from the readings on the sound-level meter, as in the following graph:>REFERENCE TO A GRAPHIC>2.1.4. Method of measurement2.1.4.1. Nature and number of measurementsThe maximum sound level expressed in A-weighted decibels (dB(A)) must be measured as the moped travels between lines AA' and BB' (figure 1). The measurement will be invalid if an abnormal discrepancy between the peak value and the general sound level is recorded. At least two measurements must be taken on each side of the moped.2.1.4.2. Positioning of the microphoneThe microphone must be located 7,5 m ± 0,2 m from the reference line CC' (figure 1) of the track and 1,2 m ± 0,1 m above ground level.2.1.4.3. Conditions of operationThe moped must approach line AA' at an initial steady speed as specified in 2.1.4.3.1. When the front of the moped reaches line AA' the throttle must be fully opened as quickly as practically possible and kept in that position until the rear of the moped reaches line BB'; the throttle must then be returned as quickly as possible to the idle position.For all measurements the moped must be ridden in a straight line over the acceleration section keeping the median longitudinal plane of the moped as close as possible to line CC'.2.1.4.3.1. Approach speedThe moped must approach line AA' at a steady speed of 30 km/h or at its top speed if this is less than 30 km/h.2.1.4.3.2. Selection of gear ratio- If the moped is fitted with a manual-shift gearbox the highest gear which allows it to cross line AA' at least half the full-power engine speed must be selected.- If the moped has an automatic transmission, it must be ridden at the speeds indicated in 2.1.4.3.1.2.1.5. Results (test report)2.1.5.1. the test report drawn up for the purpose of issuing the document referred to in Appendix 1B must indicate any circumstances and influences affecting the results of the measurements.2.1.5.2. The values taken must be rounded off to the nearest decibel.If the figure following the decimal point is between 0 and 4, the total is rounded down and if between 5 and 9, it is rounded up.Only those measurements whose variation in two consecutive tests on the same side of the moped is less than or equal to 2 dB(A) may be used for the purpose of issuing the document referred to in Appendix 1B.2.1.5.3. To take account of inaccuracies in the measurements, the result of each measurement must be arrived at by deducting 1 dB(A) from the value obtained in accordance with 2.1.5.2.2.1.5.4. If the average of the four results of the measurements does not exceed the maximum permissible level for the category to which the moped being tested belongs, the limits laid down in 2.1.1 will be deemed as being complied with.This average value will constitute the result of the test.Figure 1 Test for vehicle in motion >REFERENCE TO A GRAPHIC>Figure 2 Test for stationary vehicle >REFERENCE TO A GRAPHIC>2.2. Noise from stationary moped (measuring conditions and method for testing of the vehicle in use)2.2.1. Sound-pressure level in the immediate vicinity of the mopedIn order to facilitate subsequent noise tests on mopeds in use, the sound-pressure level must also be measured in the immediate vicinity of the exhaust-system outlet (silencer) in accordance with the following requirements, the result of the measurement being entered in the test report drawn up for the purpose of issuing the document referred to in Appendix 1B.2.2.2. Measuring instrumentsA precision sound-level meter as defined in 2.1.2.1 must be used.2.2.3. Conditions of measurement2.2.3.1. Condition of the mopedBefore the measurements are made the moped engine must be brought to the normal operating temperature. If the moped is fitted with fans with an automatic actuating mechanism, this system must not be interfered with during the sound measurements.During the measurements the gearbox must be in neutral gear. If it is impossible to disconnect the transmission, the driving wheel of the moped must be allowed to rotate freely, for example by placing the vehicle on its centre stand.2.2.3.2. Test site (Figure 2)Any area in which there are no significant acoustic disturbances may be used as a test site. Flat surfaces which are covered with concrete, asphalt or some other hard material and are highly reflective are suitable; surfaces consisting of earth which has been tamped down must not be used. The test site must be in the form of a rectangle whose sides are at least 3 m from the outer edge of the moped (handlebars excluded). There must be no significant obstacles, e.g. no persons other than the rider and the observer may stand within this rectangle.The moped must be positioned within the said rectangle so that the microphone used for measurement is at least 1 m from any kerb.2.2.3.3. MiscellaneousReadings of the measuring instrument caused by ambient noise and wind effects must be at least 10 dB(A) lower than the sound levels to be measured. A suitable windshield may be fitted to the microphone provided that account is taken of its effect on the sensitivity of the microphone.2.2.4. Method of measurement2.2.4.1. Nature and number of measurementsThe maximum sound level expressed in A-weighted decibels (dB(A)) must be measured during the period of operation laid down in 2.2.4.3.At least three measurements must be taken at each measuring point.2.2.4.2. Positioning of the microphone (Figure 2)The microphone must be positioned level with the exhaust outlet or 0,2 m above the surface of the track, whichever is the higher.

The axis of maximum sensitivity of the microphone must be parallel to the surface of the track at an angle of 45° ± 10° to the vertical plane of the direction of the exhaust emissions.In relation to this vertical plane, the microphone must be located on the side which gives the maximum possible distance between the microphone and the outline of the moped (handlebars excluded).If the exhaust system has more than one outlet at centres less than 0,3 m apart, the microphone must be faced towards the outlet which is nearest the moped (handlebars excluded) or towards the outlet which is highest above the surface of the track. If the centres of the outlets are more than 0,3 m apart, separate measurements must be taken for each of them, the highest figure recorded being taken as the test value.2.2.4.3. Operating conditionsThe engine speed must be held steady at one of the following values:-  >NUM>S >DEN>2 if S is more than 5 000 rpm,-  >NUM>3S >DEN> 4 if S is not more than 5 000 rpm,where 'S` is the speed referred to in section 3.2.1.7 of Appendix 1A.When a constant engine speed is reached, the throttle must be returned swiftly to the idle position. The sound level must be measured during an operating cycle consisting of a brief period of constant engine speed and throughout the deceleration period, the maximum sound-level meter reading being taken as the test value.2.2.5. Results (test report)2.2.5.1. the test report drawn up for the purpose of issuing the document referred to in Appendix 1B must indicate all relevant data and particularly those used in measuring the noise of the stationary moped.2.2.5.2. Values, rounded off to the nearest decibel, must be read off the measuring instrument.Only those measurements which vary by no more than 2 dB(A) in three consecutive tests will be used.2.2.5.3. The highest of the three measurements constitutes the test result.2.3. Original exhaust system (silencer)2.3.1. Requirements for silencers containing absorbent fibrous materials2.3.1.1. Absorbent fibrous material must be asbestos-free and may be used in the construction of silencers only if it is securely held in place throughout the service life of the silencer and it meets the requirements of any one of sections 2.3.1.2, 2.3.1.3 or 2.3.1.4.2.3.1.2.

The test equipment must be adjusted so that the flow of exhaust gases is alternately interrupted and restored 2 500 times by a rapid-action valve.2.3.1.4.2.3. The valve must open when the exhaust gas back-pressure, measured at least 100 mm downstream of the intake flange, reaches a value of between 0,35 and 0,40 bar. Should such a figure be unattainable because of the engine characteristics, the valve must open when the gas back-pressure reaches a level equivalent to 90 % of the maximum that can be measured before the engine stops. It must close when this pressure differs by no more than 10 % from its stabilized value with the valve open.2.3.1.4.2.4. The time-lapse relay must be set for the duration of the exhaust gases calculated on the basis of the requirements of 2.3.1.4.2.3.2.3.1.4.2.5.

Conditioning consists of three test-bench cycles.2.3.1.4.3.3. Each test-bench cycle must be followed by a break of at least 6 hours in order to reproduce the effects of cooling and condensation.2.3.1.4.3.4. Each test-bench cycle consists of six phases. The engine conditions and duration are as follows for each phase:>TABLE>2.3.1.4.3.5. During this conditioning procedure, at the request of the manufacturer, the engine and the silencer may be cooled in order that the temperature recorded at a point not more than 100 mm from the exhaust gas outlet does not exceed that measured when the moped is running at 75 % S in top gear. The engine and/or moped speeds must be determined with an accuracy of ± 3 %.Figure 3 Test apparatus for conditioning by pulsation >REFERENCE TO A GRAPHIC>>TABLE>2.3.2. Diagram and markings2.3.2.1.

DEFINITIONSFor the purposes of this Chapter:1.1. 'type of motorcycle as regards its sound level and exhaust system` means motorcycles which do not differ in such essential respects as the following:1.1.1. type of engine (two or four-stroke, reciprocating piston engine or rotary-piston engine, number and capacity of cylinders, number and type of carburettors or injection systems, arrangement of valves, net maximum power and corresponding speed).The cubic capacity of rotary-piston engines is deemed to be double the volume of the chamber;1.1.2. transmission system, in particular the number and ratios of the gears;1.1.3. number, type and arrangement of exhaust systems.1.2. 'exhaust system` or 'silencer` means a complete set of components necessary to limit the noise caused by a motorcycle engine and its exhaust.1.2.1. 'original exhaust system or silencer` means a system of the type fitted to the vehicle at the time of type-approval or extension of type-approval. It may be the one first fitted or a replacement.1.2.2. 'non-original exhaust system or silencer` means a system of a type other than that fitted to the vehicle at the time of type-approval or extension of type-approval. It may be used only as a replacement exhaust system or silencer.1.3. 'exhaust systems of differing types` means systems which are fundamentally different in one of the following ways:1.3.1. systems comprising components bearing different factory or trade marks;1.3.2. systems comprising any component made of materials of different characteristics or comprising components which are of a different shape or size;1.3.3. systems in which the operating principles of at least one component are different;1.3.4. systems comprising components in different combinations.1.4. 'component of an exhaust system` means one of the individual components which together form the exhaust system (such as exhaust pipework, the silencer proper) and the intake system (air filter) if any.If the engine has to be equipped with an intake system (air filter and/or intake noise absorber) in order to comply with the maximum permissible sound levels, the filter and/or the absorber must be treated as components having the same importance as the exhaust system.2. COMPONENT TYPE-APPROVAL IN RESPECT OF THE SOUND LEVEL AND ORIGINAL EXHAUST SYSTEM, AS A SEPARATE TECHNICAL UNIT, OF A TYPE OF MOTORCYCLE2.1. Noise of the motorcycle in motion (measuring conditions and method for testing of the vehicle during component type-approval)2.1.1. Limits: see Annex I.2.1.2. Measuring instruments2.1.2.1. Acoustic measurementsThe apparatus used for measuring the sound level must be a precision sound-level meter of the type described in International Electrotechnical Commission (IEC) publication 179 'Precision sound-level meters`, second edition. Measurements must be carried out using the 'fast` response and the 'A` weighting also described in that publication.At the beginning and end of each series of measurements the sound-level meter must be calibrated in accordance with the manufacturer's instructions, using an appropriate sound source (e.g. pistonphone).2.1.2.2. Speed measurementsEngine speed and motorcycle speed on the test track must be determined to within ± 3 %.2.1.3. Conditions of measurement2.1.3.1. Condition of the motorcycleDuring the measurements the motorcycle must be in running order (including coolant, oils, fuel, tools, spare wheel and rider).Before the measurements are made the motorcycle must be brought to the normal operating temperature. If the motorcycle is fitted with fans with an automatic actuating mechanism, this system must not be interfered with during the sound measurements. For motorcycles having more than one driven wheel, only the drive provided for normal road operation may be used. Where a motorcycle is fitted with a sidecar, this must be removed for the purposes of the test.2.1.3.2. Test siteThe test site must consist of a central acceleration section surrounded by a substantially flat test area. The acceleration section must be flat; its surface must be dry and such that surface noise remains low.On the test site the variations in the free sound field between the sound source at the centre of the acceleration section and the microphone must not exceed 1 dB. This condition will be deemed to be met if there are no large objects which reflect sound, such as fences, rocks, bridges or buildings, within 50 m of the centre of the acceleration section. The road surface covering of the test site must conform to the requirements of Annex VII.The mircrophone must not be obstructed in any way which could affect the sound field, and no person may stand between the microphone and the sound source. The observer carrying out the measurements must so position himself as not to affect the readings of the measuring instrument.2.1.3.3. MiscellaneousMeasurements must not be made in poor atmospheric conditions. It must be ensured that the results are not affected by gusts of wind.For measurements, the A-weighted sound level of sound sources other than those of the vehicle to be tested and of wind effects must be at least 10 dB(A) below the sound level produced by the vehicle. A suitable windscreen may be fitted to the microphone provided that account is taken of its effect on the sensitivity and directional characteristics of the microphone.If the difference between the ambient noise and the measured noise is between 10 and 16 dB(A), in order to calculate the test results the appropriate correction must be subtracted from the readings on the sound-level meter, as in the following graph:>REFERENCE TO A GRAPHIC>2.1.4. Method of measurement2.1.4.1. Nature and number of measurementsThe maximum sound level expressed in A-weighted decibels (dB(A)) must be measured as the motorcycle travels between lines AA' and BB' (figure 1). The measurement will be invalid if an abnormal discrepancy between the peak value and the general sound level is recorded.At least two measurements must be taken on each side of the motorcycle.2.1.4.2. Positioning of the microphoneThe microphone must be located 7,5 m ± 0,2 m from the reference line CC' (Figure 1) of the track and 1,2 m ± 0,1 m above ground level.2.1.4.3. Conditions of operationThe motorcycle must approach line AA' at an initial steady speed as specified in 2.1.4.3.1 and 2.1.4.3.2. When the front of the motorcycle reaches line AA' the throttle must be fully opened as quickly as practically possible and kept in that position until the rear of the motorcycle reaches line BB'; the throttle must then be returned as quickly as possible to the idle position.For all measurements the motorcycle must be ridden in a straight line over the acceleration section keeping the longitudinal median plane of the motorcycle as close as possible to line CC'.2.1.4.3.1. Motorcycles with non-automatic gearboxes2.1.4.3.1.1. Approach speedThe motorcycle must approach line AA' at a steady speed- 50 km/hor- corresponding to an engine speed equal to 75 % of the speed referred to in section 3.2.1.7 of Appendix 1A.The lower of these speeds must be selected.2.1.4.3.1.2. Selection of gear ratio2.1.4.3.1.2.1. Motorcycles fitted with a gearbox having a maximum of four ratios, whatever the cylinder capacity of their engines, must be tested only in second gear.2.1.4.3.1.2.2. Motorcycles fitted with engines having a cylinder capacity not exceeding 175 cm³ and a gearbox with five ratios or more must be tested only in third gear.2.1.4.3.1.2.3. Motorcycles fitted with engines having a cylinder capacity of more than 175 cm³ and a gearbox with five ratios or more must be tested once in second gear and once in third gear. The result used must be the average of the two tests.2.1.4.3.1.2.4. If, during the test carried out in second gear (see 2.1.4.3.1.2.1 and 2.1.4.3.1.2.3), the engine speed on the approach to the line marking the end of the test track exceeds 100 % of the speed referred to in section 3.2.1.7 of Appendix 1A, the test must be carried out in third gear and the sound level measured must be the only one recorded as the test result.2.1.4.3.2. Motorcycles with automatic gearboxes2.1.4.3.2.1. Motorcycles without a manual selector2.1.4.3.2.1.1. Approach speedThe motorcycle must approach line AA' at steady speeds of 30, 40 and 50 km/h or 75 % of the maximum road speed if that value is lower. The condition giving the highest sound level is chosen.2.1.4.3.2.2. Motorcycles equipped with a manual selector with X forward drive positions2.1.4.3.2.2.1. Approach speedThe motorcycle must approach line AA' at a steady speed of:- less than 50 km/h, the engine rotation speed being equal to 75 % of the speed referred to in section 3.2.1.7 of Appendix 1A,or- 50 km/h, the engine rotation speed being less than 75 % of the speed referred to in section 3.2.1.7 of Appendix 1A.If, in the test at a steady speed of 50 km/h, the gears change down to first, the approach speed of the motorcycle may be increased to a maximum of 60 km/h to avoid the changedown.2.1.4.3.2.2.2. Position of the manual selectorIf the motorcycle is equipped with a manual selector with X forward drive positions, the test must be carried out with the selector in the highest position; the voluntary device for changing down (e.g. kickdown) must not be used. If an automatic changedown takes place after line AA', the test must be begun again using the second-highest position or the third-highest position if necessary, in order to find the highest position of the selector at which the test can be performed without an automatic changedown (without using the kickdown).2.1.5. Results (test report)2.1.5.1. The test report drawn up for the purpose of issuing the document referred to in Appendix 1B must indicate any circumstances and influences affecting the results of the measurements.2.1.5.2. Readings taken must be rounded off to the nearest decibel.If the figure following the decimal point is between 0 and 4, the total is rounded down and if between 5 and 9, it is rounded up.Only those measurements whose variation in two consecutive tests on the same side of the motorcycle is less than or equal to 2 dB(A) may be used for the purpose of issuing the document referred to in Appendix 1B.2.1.5.3. To take account of inaccuracies in the measurements, the result of each measurement must be arrived at by deducting 1 dB(A) from the value obtained in accordance with 2.1.5.2.2.1.5.4. If the average of the four results of the measurements does not exceed the maximum permissible level for the category to which the vehicle being tested belongs, the limit laid down in 2.1.1 will be deemed as being complied with. This average value will constitute the result of the test.2.2. Noise from stationary motorcycle (measuring conditions and method for testing of the vehicle in use)2.2.1. Sound-pressure level in the immediate vicinity of the motorcycleIn order to facilitate subsequent noise tests on motorcycles in use, the sound-pressure level must also be measured in the immediate vicinity of the exhaust-system outlet in accordance with the following requirements, the result of the measurement being entered in the test report drawn up for the purpose of issuing the document referred to in Appendix 1B.2.2.2. Measuring instrumentsA precision sound-level meter as defined in 2.1.2.1 must be used.2.2.3. Conditions of measurement2.2.3.1. Condition of the motorcycleBefore the measurements are made the motorcycle engine must be brought to the normal operating temperature. If the motorcycle is fitted with fans with an automatic actuating mechanism, this system must not be interfered with during the sound measurements.During the measurements the gearbox must be in neutral gear. If it is impossible to disconnect the transmission, the driving wheel of the motorcycle must be allowed to rotate freely, for example by placing the vehicle on its centre stand.2.2.3.2. Test site (Figure 2)Any area in which there are no significant acoustic disturbances may be used as a test site. Flat surfaces which are covered with concrete, asphalt or some other hard material and are highly reflective are suitable; surfaces consisting of earth which has been tamped down must not be used. The test site must be in the form of a rectangle whose sides are at least 3 m from the outer edge of the motorcycle (handlebars excluded). There must be no significant obstacles, e.g. no persons other than the rider and the observer may stand within this rectangle.The motorcycle must be positioned within the said rectangle so that the microphone used for measurement is at least 1 m from any kerb.2.2.3.3.

The axis of maximum sensitivity of the microphone must be parallel to the surface of the track at an angle of 45° ± 10° to the vertical plane of the direction of the exhaust emissions.In relation to this vertical plane, the microphone must be located on the side which gives the maximum possible distance between the microphone and the outline of the motorcycle (handlebars excluded).If the exhaust system has more than one outlet at centres less than 0,3 m apart, the microphone must be faced towards the outlet which is nearest the motorcycle (handlebars excluded) or towards the outlet which is highest above the surface of the track. If the centres of the outlets are more than 0,3 m apart, separate measurements must be taken for each of them, the highest figure recorded being taken as the test value.2.2.4.3. Operating conditionsThe engine speed must be held steady at one of the following values:-  >NUM>S >DEN>2 if S is more than 5 000 rpm,-  >NUM>3S >DEN>4, if S is not more than 5 000 rpm.where S is the speed referred to in section 3.2.1.7 of Appendix 1A.When a constant engine speed is reached, the throttle must be returned swiftly to the idle position. The sound level must be measured during an operating cycle consisting of a brief period of constant engine speed and throughout the deceleration period, the maximum sound-level meter reading being taken as the test value.2.2.5. Results (test report)2.2.5.1. The test report drawn up for the purpose of issuing the document referred to in Appendix 1B must indicate all relevant data and particularly those used in measuring the noise of the stationary motorcycle.2.2.5.2. Values, rounded off to the nearest decibel, must be read off the measuring instrument.If the figure following the decimal point is between 0 and 4, the total is rounded down and if between 5 and 9, it is rounded up.Only those measurements which vary by no more than 2 dB(A) in three consecutive tests will be used.2.2.5.3.

'exhaust system` or 'silencer` means a complete set of components necessary to limit the noise caused by the engine and exhaust of a three-wheel moped or tricycle.1.2.1. 'original exhaust system or silencer` means a system of the type fitted to the vehicle at the time of type-approval or extension of type-approval. It may be the one first fitted or a replacement.1.2.2. 'non-original exhaust system or silencer` means a system of a type other than that fitted to the vehicle at the time of type-approval or extension of type-approval. It may be used only as a replacement exhaust system or silencer.1.3. 'exhaust systems of differing types` means systems which are fundamentally different in one of the following ways:1.3.1. systems comprising components bearing different factory or trade marks;1.3.2. systems comprising any component made of materials of different characteristics or comprising components which are of a different shape or size;1.3.3. systems in which the operating principles of at least one component are different;1.3.4. systems comprising components in different combinations.1.4. 'component of an exhaust system` means one of the individual components which together form the exhaust system (such as exhaust pipework, the silencer proper) and the intake system (air filter) if any.If the engine has to be equipped with an intake system (air filter and/or intake noise absorber) in order to comply with maximum permissible sound levels, the filter and/or the absorber must be treated as a component having the same importance as the exhaust system.2. COMPONENT TYPE-APPROVAL IN RESPECT OF THE SOUND LEVEL AND ORIGINAL EXHAUST SYSTEM, AS A SEPARATE TECHNICAL UNIT, OF A TYPE OF THREE-WHEEL MOPED OR TRICYCLE2.1. Noise of the three-wheel moped or tricycle (measuring conditions and method for testing of the vehicle during component type-approval).2.1.1. The vehicle, its engine and its exhaust system must be designed, constructed and assembled so that the vehicle complies with the requirements of this chapter under normal conditions of use, regardless of any vibrations to which they may be subjected.2.1.2. The exhaust system must be designed, constructed and mounted to resist the corrosion phenomena to which it is exposed.2.2. Specifications for sound levels2.2.1. Limits: see Annex I.2.2.2. Measuring instruments2.2.2.1. The apparatus used for measuring the sound level must be a precision sound-level meter of the type described in International Electrotechnical Commission (IEC) publication No 179 'Precision sound-level meters`, second edition. Measurements must be carried out using the 'fast` response of the sound-level meter and the 'A` weighting also described in that publication.At the beginning and end of each series of measurements the sound-level meter must be calibrated in accordance with the manufacturer's instructions, using an appropriate sound source (e.g. a pistonphone).2.2.2.2. Speed measurementsEngine speed and vehicle speed on the test track must be determined to within ± 3 %.2.2.3. Conditions of measurement2.2.3.1. Condition of the vehicleDuring the measurements, the vehicle must be in the running order (including coolant, oils, fuel, tools, spare wheel and rider). Before the measurements are made the vehicle must be brought to the normal operating temperature.2.2.3.1.1. The measurements must be made with the vehicles unladen and without trailer or semitrailer.2.2.3.2. Test siteThe test site must consist of a central acceleration section surrounded by a substantially flat test area. The acceleration section must be flat; its surface must be dry and such that surface noise remains low.On the test site the variations in the free sound field between the sound source at the centre of the acceleration section and the micropohone must not exceed ± 1 dB. This condition will be deemed to be met if there are no large objects which reflect sound, such as fences, rocks, bridges or buildings, within 50 m of the centre of the acceleration section. The road surface covering of the test track must conform to the requirements of Annex VII.The microphone must not be obstructed in any way which could affect the sound field, and no person may stand between the microphone and the sound source. The observer carrying out the measurements must so position himself as not to affect the readings of the measuring instrument.2.2.3.3. MiscellaneousMeasurements must not be made in poor atmospheric conditions. It must be ensured that the results are not affected by gusts of wind.For measurements, the A-weighted sound level of sound sources other than those of the vehicle to be tested and of wind effects must be at least 10 dB(A) below the sound level produced by the vehicle. A suitable windscreen may be fitted to the microphone provided that account is taken of its effect on the sensitivity and directional characteristics of the microphone.It the difference between the ambient noise and the measured noise is between 10 and 16 dB(A), in order to calculate the test results the appropriate correction must be subtracted from the readings on the sound-level meter, as in the following graph:>REFERENCE TO A GRAPHIC>2.2.4. Method of measurement2.2.4.1. Nature and number of measurementsThe maximum sound level expressed in A-weighted decibels (dB(A)) must be measured as the vehicle travels between lines AA' and BB' (figure 1). The measurement will be invalid if an abnormal discrepancy between the peak value and the general sound level is recorded.At least two measurements must be taken on each side of the vehicle.2.2.4.2. Positioning of the microphoneThe microphone must be located 7,5 m ± 0,2 m from the reference line CC' (Figure 1) of the track and 1,2 m ± 0,1 m above ground level.2.2.4.3. Conditions of operationThe vehicle must approach line AA' at an initial steady speed as specified in 2.2.4.4. When the front of the vehicle reaches line AA' the throttle must be fully opened as quickly as practically possible and kept in that position until the rear of the vehicle reaches line BB'; the throttle must then be returned as quickly as possible to the idle position.For all measurements the vehicle must be ridden in a straight line over the acceleration section keeping the median longitudinal plane of the vehicle as close as possible to line CC'.2.2.4.3.1. In the case of articulated vehicles consisting of two inseparable components and regarded as constituting one single vehicle, the semitrailer must not be taken into account with regard to crossing line BB'.2.2.4.4. Determining the steady speed to be adopted2.2.4.4.1. Vehicle without gearboxThe vehicle must approach line AA' at a steady speed corresponding either to a speed of rotation of the engine equal to three-quarters of that at which the engine develops its maximum power or to three-quarters of the maximum speed of rotation of the engine permitted by the governor, or of 50 km/h, whichever is the slowest.2.2.4.4.2. Vehicle with manual gearboxIf the vehicle is fitted with a gearbox with two, three or four ratios, second gear must be used. If the gearbox has more than four ratios, third gear must be used. If the engine then reaches a speed of rotation beyond its maximum power rating, instead of second or third gear the next higher gear to allow line BB' on the test track to be reached without exceeding this rating must be engaged. Overdrive must not be selected. If the vehicle has a dual-ratio final drive, the ratio selected must be that corresponding to the highest speed of the vehicle. The vehicle must approach line AA' at a steady speed corresponding either to three-quarters of the engine rotation speed at which the engine develops its maximum power or to three-quarters of the maximum engine rotation speed permitted by the governor, or at 50 km/h, whichever is slower.2.2.4.4.3. Vehicle with automatic gearboxThe vehicle must approach in line AA' at a steady speed of 50 km/h or three-quarters of its maximum speed, whichever is the slowest. Where several forward drive positions are available, that producing the highest average acceleration of the vehicle between lines AA' and BB' must be selected. The selector position that is used only for braking, manoeuvring or similar slow movements must not be used.2.2.5. Results (test report)2.2.5.1. The test report drawn up for the purpose of issuing the document referred to in Appendix 1B must indicate any circumstances and influences affecting the results of the measurements.2.2.5.2. The values taken must be rounded off to the nearest decibel.If the figure following the decimal point is between 0 and 4, the total is rounded down and if between 5 and 9, it is rounded up.Only those measurements whose variation in two consecutive tests on the same side of the vehicle is less than or equal to 2 dB(A) may be used for the purpose of issuing the document referred to in Appendix 1B.2.2.5.3. To take account of inaccuracies in the measurements, the result of each measurement must be arrived at by deducting 1 dB(A) from the value obtained in accordance with 2.2.5.2.2.2.5.4. If the average of the four results of the measurements does not exceed the maximum permissible level for the category to which the vehicle being tested belongs, the limit laid down in 2.2.1 will be deemed as being complied with. This average value will constitute the result of the test.2.3. Measurement of the noise of the stationary vehicle (for testing the vehicle in use)2.3.1. Sound-pressure level in the immediate vicinity of the vehicle.In order to facilitate subsequent noise tests on vehicles in use, the sound-pressure level must also be measured in the immediate vicinity of the exhaust-system outlet (silencer) in accordance with the following requirements, the result of the measurement being entered in the test report drawn up for the purpose of issuing the document referred to in Appendix 1B.2.3.2. Measuring instrumentsA precision sound-level meter conforming in accuracy to 2.2.2.1 must be used.2.3.3. Conditions of measurement2.3.3.1. Condition of the vehicleBefore the measurements are made the vehicle engine must be brought to the normal operating temperature. If the vehicle is fitted with fans with an automatic actuating mechanism, this system must not be interfered with during the sound measurements.During the measurements the gearbox must be in neutral gear. If it is impossible to disconnect the transmission, the driving wheel of the moped must be allowed to rotate freely, for example by placing the vehicle on its centre stand or on rollers.2.3.3.2. Test site (see Figure 2)Any area in which there are no significant acoustic disturbances may be used as a test site. Flat surfaces which are covered with concrete, asphalt or some other hard material and are highly reflective are suitable; surfaces consisting of earth which has been tamped down must not be used. The test site must be in the form of a rectangle whose sides are at least 3 m from the outer edge of the vehicle (handlebars excluded). There must be no significant obstacles, e.g. no persons other than the rider and the observer may stand within this rectangle.The vehicle must be positioned within the said rectangle so that the microphone used for measurement is at least 1 m from any kerb.2.3.3.3. MiscellaneousReadings of the measuring instrument caused by ambient noise and wind effects must be at least 10 dB(A) lower than the sound levels to be measured. A suitable windshield may be fitted to the microphone provided that account is taken of its effect on the sensitivity of the microphone.2.3.4. Method of measurement2.3.4.1. Nature and number of measurementsThe maximum sound level expressed in 1-weighted decibels (dB(A)) must be measured during the period of operation laid down in 2.2.4.3.At least three measurements must be taken at each measurement point.2.3.4.2. Positioning of the microphone (Figure 2)The microphone must be positioned level with the exhaust outlet or 0,2 m above the surface of the track, whichever is the highest. The microphone diaphragm must face towards the exhaust outlet at a distance of 0,5 m from it. The axis of maximum sensitivity of the microphone must be parallel to the surface of the track at an angle of 45° ± 10° to the vertical plane of the direction of the exhaust emissions.In relation to this vertical plane, the microphone must be located on the side which gives the maximum possible distance between the microphone and the outline of the vehicle (handlebars excluded).If the exhaust system has more than one outlet at centres less than 0,3 m apart, the microphone must be faced towards the outlet which is nearest the vehicle (handlebars excluded) or towards the outlet which is highest above the surface of the track. If the centres of the outlets are more than 0,3 m apart, separate measurements must be taken for each of them, the highest figure recorded being taken as the test value.2.3.4.3. Operating conditionsThe engine speed must be held steady at one of the following values:-  >NUM>S >DEN>2 if S is more than 5 000 rpm,-  >NUM>3S >DEN>4 if S is not more than 5 000 rpm,where S is the speed referred to in section 3.2.1.7 of Appendix 1A.When a constant engine speed is reached, the throttle must be returned swiftly to the idle position. The sound level must be measured during an operating cycle consisting of a brief period of constant engine speed and throughout the deceleration period, the maximum sound-level meter reading being taken as the test value.2.3.5. Results (test report)2.3.5.1. The test report drawn up for the purpose of issuing the document referred to in Appendix 1B must indicate all relevant data and particularly those used in measuring the noise of the stationary vehicle.2.3.5.2. Values, rounded off to the nearest decibel, must be read off the measuring instrument.If the figure following the decimal point is between 0 and 4, the total is rounded down and if between 5 and 9, it is rounded up.Only those measurements which vary by no more than 2 dB(A) in three consecutive tests will be used.2.3.5.3. The highest of the three measurement will constitute the test result.Figure 1 Positions for testing the vehicle in motion >REFERENCE TO A GRAPHIC>Figure 2 Positions for testing the stationary vehicle >REFERENCE TO A GRAPHIC>2.4.

REQUIRED CHARACTERISTICS OF SURFACEA surface is considered to conform to this Directive provided that the texture and voids content or sound absorption coefficient have been measured and found to fulfil all the requirements given in 1.1 to 1.4 and provided that the design requirements (section 2.2) have been met.1.1. Residual voids contentThe residual voids content, Vc, of the test track paving mixture must not exceed 8 %. See section 3.1 for measurement procedure.1.2. Sound absorption coefficientIf the surface fails to comply with the residual voids content requirement, the surface is acceptable only if its sound absorption coefficient, á, is &le; 0,10. See section 3.2 or measurement procedure.The requirement of section 1.1 and 1.2 is met also if only sound absorption has been measured and found to be: á &le; 0,10.1.3. Texture depthThe texture depth (TD) measured according to the volumetric method (see section 3.3) shall be:TD &ge; 0,4 mm.1.4. Homogeneity of the surfaceEvery practical effort must be taken to ensure that the surface is made to be as homogeneous as possible within the test area. This includes the texture and voids content, but it should also be observed that if the rolling process results in more effective rolling at some places than at others, the texture may be different and unevenness causing bumps may also occur.1.5. Period of testingIn order to check whether the surface continues to conform to the texture and voids content or sound absorption requirements stipulated in this standard, periodic testing of the surface must be performed at the following intervals:(a) for residual voids content or sound absorption:- when the surface is new.- if the surface meets the requirements when new, no further periodical testing is required.If it does not meet the requirement when it is new, it may do so later because surfaces tend to become clogged and compacted with time;(b) for texture depth (TD):- when the surface is new,- when the noise testing starts (NB: not before four weeks after laying).- then every twelve months2. TEST SURFACE DESIGN2.1. AreaWhen designing the test track layout it is important to ensure that, as a minimum requirement, the area traversed by the vehicles running through the test strip is covered with the specified test material with suitable margins for safe and practical driving. This will require that the width of the track is at least 3 m and the length of the track extends beyond lines AA and BB by at least 10 m at either end. Figure 1 shows a plan of a suitable test site and indicates the minimum area which, must be machine laid and machine compacted with the specified test surface material.Figure 1 Minimum requirements for test surface area >REFERENCE TO A GRAPHIC>2.2. Design requirements for the surfaceThe test surface must meet four design requirements:1. it must be a dense asphaltic concrete;2. the maximum chipping size must be 8 mm (tolerances allow from 6,3 to 10 mm);3. the thickness of the wearing course must be &ge; 30 mm;4. the binder must be a straight penetration grade bitumen without modification.As a guide to the test surface constructor, an aggregate grading curve which will give desired characteristics is shown in figure 2. In addition, table 3 gives some guidelines in order to obtain the desired texture and durability. The grading curve fits the following formula:P (% passing) = 100 (d/dmax) ½whered = square mesh sieve size, in mmdmax = 8 mm for the mean curvedmax = 10 mm for the lower tolerance curvedmax = 6,3 mm for the upper tolerance curveIn addition to the above, the following recommendations are given:- the sand fraction (0,063 mm REFERENCE TO A GRAPHIC>>TABLE>3. TEST METHODS3.1. Measurement of the residual voids contentFor the purpose of this measurement, cores have to be taken from the track at least at four different positions which are equally distributed in the test area between lines AA and BB (see figure 1). In order to avoid inhomogeneity and unevenness in the wheel tracks, cores should not be taken in the wheel tracks themselves, but close to them. Two cores (minimum) should be taken close to the wheel tracks and one core (minimum) should be taken approximately midway between the wheel tracks and each microphone location.If there is a suspicion that the condition of homogeneity in not met (see section 1.4), cores should be taken from more locations within the test area.The residual voids content has to be determined for each core. Then the average value from all cores is calculated and compared with the requirement of section 1.1. In addition, no single core should have a voids value which is higher than 10 %.The test surface constructor is reminded of the problem which may arise when the test area is heated by pipes or electrical wires and cores must be taken from this area. Such installations must be carefully planned with respect to future core drilling locations. It is recommended to leave a few locations of size approximately 200 × 300 mm where there are no wires or pipes, or where the latter are located deep enough in order not to be damaged by cores taken from the surface layer.3.2. Sound absorption coefficientThe sound absorption coefficient (normal incidence) is measured by the impedance tube method using the procedure specified in ISO/DIS 10534: 'Acoustics - Determination of sound absorption coefficient and impedance by a tube method`.Regarding test specimens, the same requirements are followed as regarding the residual voids content (see section 3.1).The sound absorption is measured in the range 400 to 800 Hz and in the range 800 to 1 600 Hz (at least at the centre frequencies of third octave bands) and the maximum values shall be identified for both of these frequency ranges. Then these values, for all test cores, are averged to constitute the final result.3.3. Volumetric macrotexture measurementFor the purposes of this standard, texture depth measurements are made on at least 10 positions evenly spaced along the wheel tracks of the test strip and the average value taken to compare with the specified minimum texture depth. See Annex F to Draft Standard ISO/DIS 10844 for a description of the procedure.4. STABILITY IN TIME AND MAINTENANCE4.1. Age influenceIn common with many other surfaces, is it expected that the tyre/road noise levels measured on the test surface may increase slightly during the first six to 12 months after construction.The surface will achieve its required characteristics not earlier than four weeks after construction.The stability over time is determined mainly by the polishing and compaction by vehicles driving on the surface. It must be periodically checked as stated in section 1.5.4.2. Maintenance of the surfaceLoose debris or dust which could significantly reduce the effective texture depth must be removed from the surface. In countries with winter climates, salt is sometimes used for de-icing. Salt may alter the surface temporarily or even permanently in such a way as to increase noise and is therefore not recommended.4.3. Repaving the test areaIf it is necessary to repave the test track, it is usually unnecessary to repave more than the test strip (of 3 m width in figure 1) where vehicles are driving provided the test area outside the strip met the requirement of residual voids content or sound absorption when it was measured.5. DOCUMENTATION OF THE SURFACE AND OF TESTS PERFORMED ON IT5.1. Documentation of the test surfaceThe following data must be given in a document describing the test surface:(a) the location of the test track;(b) type of binder, binder hardness, type of aggregate, maximum theoretical density of the concrete ('DR`), thickness of the wearing course and grading curve determined from cores from the test track;(c) method of compaction (e.g. type of roller, roller mass, number of passes);(d) temperature of the mix, temperature of the ambient air and wind speed during laying of the surface;(e) date when the surface was laid and contractor;(f) all or at least the latest test result, including:(i) the residual voids content of each core;(ii) the locations in the test area from where the cores for voids measurement have been taken;(iii) the sound absorption coefficient of each core (if measured). Specify the results both for each core and each frequency range as well as the overall average;(iv) the locations in the test area from where the cores for absorption measurement have been taken;(v) texture depth, including the number of tests and standard deviation;(vi) the institution responsible for tests (i) and (iii) and the type of equipment used;(vii) date of the test(s) and date when the cores were taken from the test track.5.2. Documentation of vehicle noise tests concluded on the surfaceIn the document describing the vehicle noise test(s) it must be stated whether all the requirements were fulfilled or not.

This Annex I states the requirements which coupling devices for two and three-wheel motor vehicles must satisfy in order to- ensure compatibility when combining motor vehicles with different types of trailers;- ensure the safe coupling together of the vehicles under all conditions of use;- ensure safe procedures for coupling and uncoupling.2. DEFINITIONS2.1. 'Coupling devices for motor vehicles` means all parts and devices fitted to the frames, load-bearing parts of the bodywork and chassis of the vehicles by means of which towing and towed vehicles are connected together.They also include fixed or detachable parts for the attachment, adjustment or operation of the abovementioned coupling devices.2.1.1. 'Coupling balls and towing brackets` means coupling devices employing a spherical device and brackets on the motor vehicle for connecting to the trailer by means of a coupling head.2.1.2. The coupling heads in 2.1.1 are mechanical coupling devices on the drawbar of trailers for connecting to a coupling ball on the motor vehicle.3. GENERAL REQUIREMENTS3.1. The coupling devices for two and three-wheel motor vehicles must be manufactured and attached in accordance with good engineering practice, and must be safe to operate.3.2. The coupling devices must be so designed and manufactured that in normal use, with proper maintenance and the timely replacement of wearing parts, they will continue to function satisfactorily.3.3. Every coupling device must be accompanied by installation and operating instructions giving sufficient information for a competent person to install it on the vehicle and operate it properly. The instructions must be in the official language or languages of the Member State in which the coupling device will be offered for sale.3.4. The materials that may be used are those for which the properties relevant to the application are laid down in a standard or those for which the properties are given in the application documentation.3.5. All parts of the coupling devices whose failure could result in separation of the two vehicles must be made of steel.Other materials may be used provided equivalence has been demonstrated by the manufacturer to the satisfaction of the Technical Service.3.6. All couplings must be designed for positive mechanical engagement, and the closed position must be secured at least once by positive mechanical engagement.3.7. In principle coupling balls in accordance with Appendix 1, Figure 1 are to be used on two and three-wheel motor vehicles. In the case of three-wheel vehicles particularly, the coupling type must be chosen and positioned to allow maximum compatibility with a range of trailer types. Devices other than coupling balls may be used, provided the requirements of 3.8 are met and that compatibility and interchangeability of trailers is neither necessary nor possible (dedicated combinations).3.8. Coupling devices must be designed in a way to meet the requirements for case of operation, position, mobility and strength according to Sections 3.9, 3.10, 3.11, 4, 5 and 6.3.9. The coupling devices must be designed and attached in a way to achieve maximum safety according to good engineering practice; this also applies to the operation of the coupling.3.10. Safe coupling and uncoupling of the vehicles must be possible by one person without the use of tools.3.11. The operation of detachable coupling devices must be possible easily by hand and without the use of tools.4. REQUIREMENTS FOR POSITION4.1. Coupling devices attached to the vehicles must ensure an unhindered and safe operation.4.2. Coupling balls attached to the vehicles must correspond to the geometric conditions specified in Appendix 1, Figure 2.4.3. The height of the coupling point of a coupling device other than a coupling ball must correspond to the height of the coupling point of the drawbar of the trailer within a range of ± 35 mm, provided the trailer is in a horizontal position.4.4. The shape and the dimensions of the towing brackets must correspond to the vehicle manufacturer's requirements with respect to fixing points and any additional mounting devices required.4.5. The requirements of the vehicle manufacturer with regard to the type of the coupling device, the permissible mass of the trailer and the permissible static vertical load imposed at the coupling point must be observed.4.6. The mounted coupling device must not obscure the visibility of the rear licence plate, otherwise a coupling device which can be dismantled without special tools has to be used.5. REQUIREMENTS FOR ARTICULATION5.1. The following articulation must be possible with the coupling device not attached to the vehicle.5.1.1. An angle of free vertical pitch of 20° above and below the horizontal centre line at all angles of horizontal rotation up to at least 90° each side of the longitudinal centre line of the device.5.1.2. At all angles of horizontal rotation up to 90° each side of the longitudinal centre line of the device there must be an angle of free axial roll each side of the vertical centre line of 25° for three-wheel vehicles or 40° for two-wheel vehicles.5.2. At all angles of horizontal rotation the following combinations of articulation must be possible:in the case of two-wheel vehicles, except where the device is used with one-wheel trailers which tilt with the two-wheel motor vehicle:- vertical pitch of ± 15° with axial roll of ± 40°,- axial roll of ± 30° with vertical pitch of ± 20°;in the case of three-wheel vehicles or quadricycles:- vertical pitch of ± 15° with axial roll of ± 25°- axial roll of ± 10° with vertical pitch of ± 20°.5.3. It must also be possible to couple and uncouple ball couplings when the longitudinal axis of the ball coupling in relation to the centre line of the coupling ball and mounting:- is horizontally â = 60° right or left- is vertically á = 10° up or down- is axially rotated 10° right or left.6. REQUIREMENTS FOR STRENGTH6.1. A dynamic strength test (endurance test) must be performed.6.1.1. The endurance test is performed with an alternating approximately sinusoidal load with a number of load cycles depending on the material. No cracks or fractures or other visible external damage, or any excessive permanent distortion which would be detrimental to the satisfactory operation of the device must occur.6.1.2. The loading basis for the dynamic test is the D-value shown below. The static vertical load is taken into consideration in the direction of the test load relative to the horizontal plane, depending on the position of the coupling point and the static vertical load permitted at the coupling point.D = g ×  >NUM>T × R >DEN>T + R kNwhereT = technically permissible maximum mass in tonnes of the towing vehicleR = technically permissible maximum mass in tonnes of the trailerg = acceleration due to gravity (assumed g = 9,81 m/s²)6.1.3. The characteristic values D and S on which the test is to be based are specified in the manufacturer's EC type-approval application, S being the permitted maximum static vertical load at the coupling point in kg.6.2. Test procedures6.2.1. For the dynamic tests the sample must be placed in a suitable rig with a suitable means of force application so that it is not subjected to any additional forces or moments apart from the specified test force. In the case of alternating tests the direction of force application must not deviate by more than ± 1° from the specified direction. To avoid unspecified forces and moments in the sample it may be necessary to have one joint at the point of force application and a second joint an adequate distance away.6.2.2. The test frequency must not exceed 35 Hz. The selected frequency must be well separated from resonant frequencies of the test set up including the device being tested. The number of load cycles must be 2 × 106 for coupling devices made of steel. A higher number of load cycles may be required for coupling devices made of other materials. Generally, the crack test is to be performed in accordance with the dye penetration procedure; equivalent other procedures are also permissible.6.2.3. The coupling devices on test are normally mounted as rigidly as possible on a test rig in the actual position in which they will be used on the vehicle. The fixing devices must be those specified by the manufacturer or applicant and be those intended for its attachment to the vehicle and/or have identical mechanical characteristics.6.2.4. Preferably, couplings have to be tested in original condition as intended for use on the road. At the discretion of the manufacturer and in agreement with the Technical Service, flexible components may be neutralized if this is necessary for the test procedure and if there is no concern about unrealistic influence on the test result.Flexible components which are obviously overheated due to this accelerated test procedure may be replaced during the test.The test loads may be applied by means of special slackfree devices.The devices submitted for test must be provided with all design details which may have an influence on the strength criteria (for example electrical socket plates, any markings, etc.). The test periphery ends at the anchorage points or fitting points. The geometric location of the coupling ball and the fixing points of the coupling device related to the reference line must be provided by the vehicle manufacturer and shown in the test report.All relative positions of the attachment points with respect to the reference line as shown in Appendix 2, for which the towing vehicle manufacturer must provide all the necessary information to the towing device manufacturer, must be repeated on the test bed.6.3. Test of coupling balls and towing brackets6.3.1. The assembly mounted on the test bed is subjected to a dynamic test on an alternating stress tensile testing machine (example on a resonance pulser).The test load must be an alternating force and applied to the coupling ball at an angle of 15° ± 1° as shown in Appendix 2, Figure 3 and Figure 4. If the ball centre is above that line parallel to the reference line as shown in Appendix 2, Figure 5, which contains the highest of the nearest fixing points, the test must be carried out with an angle á = - 15° ± 1° (Appendix 2, Figure 3). If the ball centre is below that line parallel to the reference line as shown in Appendix 2, Figure 5 which contains the highest of the nearest fixing points, the test must be carried out with an angle á = + 15° ± 1° (Appendix 2, Figure 4). This angle is chosen in order to take account of the vertical static and dynamic load. This test method is only applicable to a permitted static load of not more thanS =  >NUM>120 7D >DEN>gIf a static load aboveS =  >NUM>120 7D >DEN>gis requested, the test angle must be increased to 20°.The dynamic test must be performed with the following test force:Fres = ± 0,6 D6.3.2. One-piece coupling balls including devices with non-interchangeable detachable balls and towing brackets with interchangeable balls which can be dismantled (excluding balls on integral support) are tested in accordance with 6.3.1.6.3.3. The test of a towing bracket which can be used with different ball units is carried out in accordance with the test requirements of Annex VI, section 4.1.6 of Directive 94/20/EC (OJ No L 195, 29. 7. 1994, p. 1).6.4. The abovementioned testing requirements in 6.3.1 are also applicable to coupling devices other than coupling balls.7. COUPLING HEADS7.1. The basic test is an endurance test with an alternating test force and a static test (lifting test) on each test sample.7.2. The dynamic test must be performed with a suitable coupling ball of appropriate strength. On the test rig the coupling head and the ball coupling must be arranged as instructed by the manufacturer and in a way corresponding to their attachment in a vehicle. There must be no possibility of extra forces in addition to the test force acting on the sample.The test force must be applied along a line passing through the centre of the ball and inclined downwards to the rear at 15° (see Appendix 3, Figure 6). An endurance test must be performed on a test sample with the following test force:Fres = ± 0,6 D7.3. A static lifting test must also be performed (see Appendix 3, Figure 7). The coupling ball used for the test must have a diameter of>START OF GRAPHIC>49+0,13- 0mm>END OF GRAPHIC>in order to represent a worn coupling ball. The lifting force FA must be increased smoothly and quickly to a value ofg × (C +  >NUM>S >DEN>1 000)and held for 10 seconds, whereC = mass of the trailer (sum of the axle loads of the trailer carrying maximum permissible load) in tonnes.7.4. If coupling devices other than ball couplings are used, the coupling head must be tested, as applicable, in accordance with the relevant requirements of Directive 94/20/EC.8. MARKINGCoupling devices must be marked in accordance with the relevant requirements of Directive 94/20/EC.Appendix 1 Ball coupling on two or three-wheel motor vehiclesThe ball coupling system for trailers does not exclude the use of other systems (for instance cardan couplings); however, if a ball-coupling system is used, this system must correspond to the specification laid down in Figure 1.Figure 1 >REFERENCE TO A GRAPHIC>(1) The connecting radius between the ball and the neck is tangential both to the neck and to the lower horizontal surface of the coupling ball.(2) See ISO/R 468 and ISO 1302; the roughness number N9 refers to an Ra value of 6,3 ìm.Figure 2 Clearance space for coupling balls >REFERENCE TO A GRAPHIC>Appendix 2 The test direction is shown by the example of a coupling ball with towing bracket.

GENERAL REQUIREMENTS2.1. The safety-belt anchorages must be designed, manufactured and installed in such a way:2.1.1. as to permit the fitting of an appropriate safety-belt. The anchorages for the front outboard seats must permit the use of belts incorporating an inertia reel and reverser returning to the upper anchorage, having regard in particular to the strength characteristics of the anchorages, unless the manufacturer supplies the vehicle fitted with other types of belt incorporating inertia reels. If the anchorages are suitable only for certain types of belt, those types must be mentioned in the document set out in Annex V, Appendix 1;2.1.2. as to reduce to a minimum the risk of belt slippage when the belt is worn correctly;2.1.3. as to reduce to a minimum the risk of deterioration of the strap as a result of contact with the rigid sharp parts of the structure of the vehicle or seat;2.1.4. that, under normal conditions of use, the vehicle may fulfil the requirements of this Chapter;2.1.5. that, where anchorages adopt different positions in order to enable persons to enter the vehicle and in order to retain the occupants, the specifications of this Directive apply to anchorages in their effective retention position.2.2. Safety-belt anchorages are not required for bodied three-wheel mopeds or quadricycles having an unladen mass of not more than 250 kg. Where such vehicles are fitted with anchorages, however, those anchorages must meet the requirements of this Chapter.3. MINIMUM NUMBER OF BELT ANCHORAGES3.1. Two lower and one upper anchorage must be provided for the front seats. However, two lower anchorages are considered sufficient for the front centre seats, if fitted, where there are other front seats and the windscreen is located outside the reference zone defined in Annex II to Directive 74/60/EEC. The windscreen is considered as forming part of the reference zone for the anchorages should the windscreen enter into static contact with the device for testing in accordance with the method described in Annex II to Directive 74/60/EEC on the interior fittings of motor vehicles (1).3.2. for the outboard seats two lower anchorages and one upper anchorage must be provided.3.3. with the exception of the tip-up seat for which anchorages are not required, at least two lower anchorages must be provided for all other forward-facing seats.3.4. If the vehicle is fitted with anchorages for tip-up seats, the anchorages must comply with this Chapter.4. POSITIONING OF SAFETY-BELTS(see Annex II, figure 1)4.1. General4.1.1. The anchorages for any one belt may all be attached to the structure of the vehicle, or of the seat or to any other part of the vehicle, or be divided among those various positions.4.1.2. The same anchorage may receive the ends of two adjancent belts provided that the test requirements are met.4.2. Position of lower effective anchorages4.2.1. The á1 and á2 angles must lie between 30° and 80° in all of the normal positions of use of the seat.4.2.2. Where rear-seat benches and adjustable seats are provided with the adjustment system defined in 1.12 and their backrest angle is less than 20° (see Annex II, figure 1) the á1 and á2 angles may be less than the minimum values specified in 4.2.1 provided that they are not less than 20° in any of the normal positions of use of the seat.4.2.3. The distance between the two vertical planes parallel to the median longitudinal plane of the vehicle and passing through each of the two lower effective anchorages L1 and L2 of the same belt must not be less than 350 mm. The median longitudinal plane of the seat must pass points L1 and L2 at no less than 120 mm from those points.4.3. Position of the upper effective anchorages(see Annex II, figure 2)4.3.1. If a strap guide or similar device affecting the position of the effective upper anchorages is used, that position is determined in a conventional manner by considering the position of the anchorage when the central longitudinal line of the strap passes through J1 defined successively from the R point via the following three segments:- RZ: segments of reference line measured form the R point upwards along the length 530 mm;- ZX: segment perpendicular to the median longitudinal plane of the vehicle measured from the Z point in the direction of the anchorage and having a length of 120 mm;- XJ1: segment perpendicular to the plane defined by segments RZ and ZX measured form point X forwards over a length of 60 mm;Point J2 is determined by symmetry with point J1 about the longitudinal plane vertically crossing the reference line (defined in 1.20) of the dummy placed in the relevant seat.4.3.2. The upper effective anchorage must lie below the plane FN that is perpendicular to the median longitudinal plane of the seat and forms an angle of 65° with the reference line. For the rear seats this angle may be reduced to 60°. Plane FN must be located in such a way as to intersect the reference line at a point D such that DR = 315 mm + 1.8 S.However if S does not exceed 200 mm, DR = 675 mm.4.3.3. The upper effective anchorage of the belt must lie behind plane FK perpendicular to the median longitudinal plane of the seat and intersecting the reference line at an angle of 120° at a point B such that BR = 260 mm + S. If S is not less than 280 mm the manufacturer may opt to use BR = 260 mm + 0,8 S.4.3.4. The value S must not be less than 140 mm.4.3.5. The upper effective anchorage must be located behind a vertical plane that is perpendicular to the median longitudinal plane of the vehicle and passes through the R point as shown in the diagram in Annex II.4.3.6. The upper effective anchorage of the belt must be located above the horizontal plane passing through the C point defined in 1.22.4.3.7. In addition to the upper anchorage referred to in 4.3.1 other upper effective anchorages may be fitted if one of the following conditions is met:4.3.7.1. the additional anchorages meet the requirements of 4.3.1 to 4.3.6;4.3.7.2. the upper anchorages may be used without the aid of tools, meet the requirements of 4.3.5 and 4.3.6 and lie within one of the specified areas by moving the area bounded in figure 1 in Annex II by 80 mm upwards or downwards in a vertical direction;4.3.7.3. the anchorage(s) is (are) intended for a harness-type belt and meet(s) the requirements set out in 4.3.6 if they lie behind the transverse plane passing through the reference line and is (are):4.3.7.3.1. where there is a single anchorage, located within the area common to two dihedrals bounded by vertical lines passing through the points J1 and J2 defined in 4.3.1, the horizontal sections of which are defined by figure 2 in Annex II;4.3.7.3.2. if there are two anchorages, located within whichever of the two above dihedrals is suitable, provided that no anchorage is more than 50 mm from the symmetrical seat located opposite the other anchorage, about plane P (defined in 1.24) of the seat under consideration.5. STRENGTH OF ANCHORAGES5.1. Each anchorage must be able to withstand the tests provided for in 6.3 and 6.4. Permanent deformation, including partial rupture of an anchorage or the surrounding area does not constitute failure if the required force is sustained for the specified time. During the test the minimum distances for the lower effective anchorages required in 4.2.3 and the requirements set out in 4.3.6 and 4.3.7 for upper effective anchorages must be maintained.5.2. In the vehicles in which these devices are used the movement and locking systems enabling the occupants of all the seats to exit from the vehicle must still be capable of being manually activated after the tractive force has ceased to be applied;5.3. Dimensions of threaded holes for anchoragesThe threaded holes for the anchorages must be of the 7/16-20 UNF 2 B type in accordance with ISO Standard TR 1417.5.4. If the manufacturer has fitted the vehicle with safety-belts that have been attached at all of the anchorages required for a particular seat, it is not necessary that those anchorages meet the requirements of 5.3 provided that they meet the other requirements of this Chapter. Moreover, the requirement set out in 5.3 does not apply to additional anchorages meeting the requirement set out in 4.3.7.3.5.5. It must be possible to remove the safety-belt from the anchorage without damage to the anchorage.6. TESTS6.1. General6.1.1. Subject to the implementation of the provisions set out in 6.2 and in line with the manufacturer's request,6.1.1.1. the tests may concern either a vehicle structure or a fully finished vehicle;6.1.1.2. the windows and doors may be installed or not and closed or not;6.1.1.3. any normally intended component which is likely to contribute to structural rigidity may be installed.6.1.2. The seats must be installed and adjusted to their driving position or position of use selected by the testing body responsible for the component type-approval tests as being the least favourable from a system-strength point of view.The position of the seats must be stated in the report. If its angle is adjustable the backrest must be locked in position in accordance with the manufacturer's instructions or, in their absence, in a position corresponding to an effective seat angle as close as possible to 15° and in the case of a quadricycle to 25°.6.2. Vehicle restraint6.2.1. The method used to restrain the vehicle during the test must not cause the anchorage or anchorage areas to be reinforced or reduce the normal deformation of the structure.6.2.2. A restraint device is considered satisfactory if it has no effect on an area extending throughout the width of the structure and if the vehicle or structure is locked or attached at the front at a distance of at least 500 mm from the anchorage to be tested and held or attached at the rear at least 300 mm from said anchorage.6.2.3. It is recommended that the structure be made to rest on supports directly below the wheel axes or if that is not possible directly below the suspension points.6.3. General test requirements6.3.1. All the anchorages within the same group of seats must be tested simultaneously.6.3.2. The tractive force must be applied forwards at an angle of 10° ± 5° above the horizontal in a plane parallel to the median longitudinal plane of the vehicle.6.3.3. The loading must begin as quickly as possible. The anchorages must withstand the specified load for at least 0,2 s.6.3.4. The traction devices to be used for the tests described in 6.4 are shown in Annex IV.6.3.5. The anchorages for seats fitted with upper anchorages must be tested under the following conditions:6.3.5.1. Outboard front seats:The anchorages are subjected to the test required in 6.4.1 in which the forces are applied to them by means of a device reproducing the geometry of a three-point belt incorporating an inertia reel and a reverser back up to the upper anchorage.Moreover, when there are more anchorages than the number required by section 3, those anchorages must be subjected to the test required in 6.4.5, during which the forces are applied to them by means of a device reproducing the geometry of the type of safety-belt intended to be attached to those anchorages.6.3.5.1.1. When the inertia reel is not attached to the lower side anchorage which must be provided for, or where the inertia reel is attached to the upper anchorage, the lower anchorages must also be subjected to the test required in 6.4.3.6.3.5.1.2. In the above instance the tests required in 6.4.1 and 6.4.3 may be carried out on two different structures at the request of the manufacturer.6.3.5.2. Rear outboard seats and/or central seats:The anchorages must be subjected to the test required in 6.4.2 in which the forces are transferred to them by means of a device reproducing the geometry of a three-point non-inertia reel belt, and the test required in 6.4.3 in which the forces are transferred to the lower anchorages by means of a device representing a lap belt. The two tests may be carried out on two different structures at the request of the manufacturer.6.3.5.3. By way of derogation from the requirements of 6.3.5.1 and 6.3.5.2, where a manufacturer delivers his vehicle fitted with belts including inertia reels the corresponding anchorages must be subjected to the test in which the forces are transferred to them by means of a device reproducing the geometry of the belt(s) for which the anchorages must be component type-approved.6.3.6. Where there are no upper anchorages for the outboard side seats and central seats, the lower anchorages must be subjected to the test required in 6.4.3 in which the forces are transferred to them by means of a device reproducing the geometry of a lap belt.6.3.7. If the vehicle is designed to receive other devices which do not enable the straps to be attached directly to the anchorages without the use of intermediate rollers, etc. or which require anchorages additional to those referred to in section 3, the belt or assembly of cables, rollers, etc. representing the belt equipment must be attached by means of such a device to the anchorages on the vehicle and those anchorages subjected to the test required in 6.4 as appropriate.6.3.8. A test method other than those required in 6.3 may be used but its equivalence must be demonstrated.6.4. Specific requirements for the tests to be carried out on vehicles having an unladen mass of not more than 400 kg (2) (or 550 kg if the vehicles are to be used for the transport of goods)6.4.1. Test in three-point belt configuration incorporating an inertia reel with reverser attached to the upper anchorage.6.4.1.1. A special reverser for the cable or strap having the characteristics needed in order to transfer the forces from the traction device, or the reverser supplied by the manufacturer, is attached to the upper anchorages.6.4.1.2. A test loading of 675 daN ± 20 daN is applied to a traction device (see Annex IV, figure 2) attached to the belt anchorages by means of a device reproducing the geometry of the upper diagonal strap of that belt.6.4.1.3. At the same time a tractive force of 675 daN ± 20 daN is applied to a traction device (see Annex IV, figure 1) attached to the two lower anchorages.6.4.2. Test in three-belt configuration without inertia reel or with inertia reel on the upper anchorage.6.4.2.1. A test loading of 675 daN ± 20 daN is applied to a traction device (see Annex IV, figure 2) attached to the upper anchorage and the opposite lower anchorage for the same belt, by using a retractor attached to the upper anchorage if such a device is supplied by the manufacturer.6.4.2.2. At the same time a traction force of 675 daN ± 20 daN is applied to a traction device (see Annex IV, figure 1) attached to the lower anchorages.6.4.3. Test in lap-belt configuration6.4.3.1. A test loading of 1 110 daN ± 20 daN is applied to a traction device (see Annex IV, figure 1) attached to the two lower anchorages.6.4.4. Anchorage test, with the anchorages either all attached to the seat structure or distributed among the vehicle structure and the seat structure.6.4.4.1. Depending on the case the tests specified in 6.4.1, 6.4.2 and 6.4.3 must be carried out by adding, for each seat and each group of seats, the additional force stated below.6.4.4.2. In addition to the force referred to in 6.4.1, 6.4.2 and 6.4.3, a longitudinal and horizontal force equal to ten times the weight of the complete seat is applied to the centre of gravity of the seat.6.4.5. Test in special-type belt configuration.6.4.5.1. A test loading of 675 daN ± 20 daN is applied to a traction device (see Annex IV, figure 2) attached to the anchorages for a safety-belt of this type by means of a device reproducing the geometry of the upper diagonal strap or straps.6.4.5.2. At the same time a tractive force of 675 daN ± 20 daN is applied to the traction device (see Annex IV, figure 3) attached to the lower anchorages.6.5. Specific requirements for the tests to be carried out on vehicles having an unladen mass of more than 400 kg (or 550 kg if the vehicles are assigned to the transport of goods)The requirements set out in Annex I to Directive 76/115/EEC (3) concerning the specific test methods on safety-belt anchorages for motor vehicles of category M1 apply.7. CHECKING AFTER THE TESTSAny deterioration in the anchorages and load supporting structures during the tests must be recorded after the tests.(1) OJ No L 38, 11. 2. 1974, p. 2.(2) The mass of the traction batteries for electric vehicles is not included in the unladen mass.(3) OJ No L 24, 30. 1. 1976, p. 6.ANNEX II Figure 1 Effective anchorage attachment areas >REFERENCE TO A GRAPHIC>Figure 2 Effective upper anchorages in accordance with section 4.3.7.3 of Annex I >REFERENCE TO A GRAPHIC>ANNEX III PROCEDURE TO BE FOLLOWED IN ORDER TO DETERMINE THE POSITION OF THE H POINT AND THE TRUE BACKREST RAKE ANGLE AND TO CHECK THEIR RELATIONSHIP WITH THE POSITION OF THE R POINT AND THE INTENDED BACKREST RAKE ANGLE 1. DEFINITIONS1.1. The H point which characterizes the position within the passenger compartment of a seated occupant is the trace, in a vertical longitudinal plane, of the theoretical axis of rotation between the legs and trunk of a human body, as represented by the dummy described in section 3 below.1.2. The R point or the 'seated position reference point` is the reference point stated by the manufacturer which:1.2.1. has coordinates determined in relation to the structure of the vehicle;1.2.2. corresponds to the theoretical position of the trunk/leg rotation point (H point) for the lowest and most rearward normal driving position or position of use given by the vehicle manufacturer for each seating position specified by him.1.3. 'Backrest rake angle` is the inclination of the seat back in relation to the vertical.1.4. The 'true backrest rake angle` is the angle formed by the vertical line passing through the H point and the reference line for the trunk of the human body represented by the dummy described in section 3 below.1.5. The 'intended backrest rake angle` is the angle specified by the manufacturer which:1.5.1. determines the backrest rake angle for the lowest and most rearward normal driving position or position of use given by the vehicle manufacturer for each seating position specified by him;1.5.2. is formed at the point R by the vertical line and the trunk reference line;1.5.3. corresponds theoretically to the true rake angle.2. DETERMINATION OF THE H POINTS AND TRUE BACKREST RAKE ANGLES2.1. A H point and a true backrest rake angle must be determined for each seat provided by the manufacturer. Where the seats in the same row can be regarded as similar (bench seat, identical seats, etc.), only one H point and one true backrest rake angle is determined for each row of seats, the dummy described in section 3 below being seated in a place regarded as representative for the row. This place is:2.1.1. in the case of the front row, the driver's seat;2.1.2. in the case of the rear row (or rows), an outboard seat.2.2. When a H point and a true backrest rake angle is being determined, the seat in question is placed in the rearmost normal position provided by the manufacturer for driving or travelling, the back, if adjustable, being locked in a position specified by the manufacturer or, in the absence of any specification, in a manner such that the real rake angle is between 25° and 15°.3. DUMMY CHARACTERISTICS3.1. A three-dimensional dummy is used, with a mass and contour of an average-size adult. Figures 1 and 2 in the Appendix to this Annex show a diagram of this dummy.3.2. The dummy comprises:3.2.1. two parts, one simulating the back and the other the pelvis of the body, jointed along an axis representing the axis of rotation between the thorax and thighs. The trace of that axis on the flank of the dummy is the H point of that dummy;3.2.2. two components simulating the legs and jointed in relation to the part simulating the pelvis;3.2.3. two components simulating the feet, linked to the legs by joints simulating the ankles;3.2.4. moreover, the component simulating the pelvis is equipped with a level gauge enabling its transverse lean to be checked;3.3. Ballast representing the weight of each body component is located at the appropriate points constituting the corresponding centres of gravity in order to obtain a total dummy mass of approximately 75,6 kg. The details of the different ballast weights are given in Figure 2 in the Appendix.3.4. The reference line for the trunk of the dummy is taken into account via a straight line passing through the joint between the leg and the pelvis and the theoretical joint between the neck and thorax (see Figure 1 in the Appendix).4. PLACING IN POSITION OF DUMMYThe three-dimensional dummy is placed in position as follows:4.1. The vehicle is placed on a horizontal plane and the seats adjusted as described in 2.2;4.2. the seat to be tested is covered with a piece of cloth intended to ease the correct placing in position of the dummy;4.3. the dummy is sat in the position under examination, its swivel axis being at right angles to the median longitudinal plane of symmetry of the vehicle;4.4. the feet of the dummy are located as follows:4.4.1. when the dummy is placed on the front seats, it must be positioned such that the level guage enabling the transverse lean of the seat to be checked is brought into the horizontal;4.4.2. when the dummy is on the rear seats, its feet must be arranged in such a way that, as far as possible, they are in contact with the front seats. If the feet then rest upon parts of the floor that are at different levels the foot that is the first to come into contact with the front seat serves as a reference and the other foot is arranged in such a way that the level gauge enabling the transverse lean of the seat to be checked is brought into the horizontal;4.4.3. if the H-point is determined at a central seat the feet are placed either side of the tunnel;4.5. the ballast masses are placed on the thighs, the level gauge for the transverse lean of the seat brought into the horizontal and the ballast masses placed on the component representing the seat of the dummy;4.6. the dummy must be moved away form the seat backrest using the knee pivot rod and its back pivoted forwards. The dummy is repositioned on the seat by sliding its seating support backwards until resistance is met, then pivoting its back rearwards until it is supported by the seat backrest;4.7. a horizontal force of approximately 10 ± 1 daN is then applied twice to the dummy. The direction and point of application of the force are represented by a black arrow in Figure 2 of the Appendix;4.8. the ballast masses are then placed on the right and left flanks, followed by the bust masses. The transverse level of the dummy must be kept horizontal;4.9. while the transverse level gauge of the dummy is maintained in a horizontal position the back is brought forwards until the bust masses are above the H point in such a way as to cancel out any rubbing against the seat backrest;4.10. the back must then be carefully moved rearwards in such a way as to complete the placing in position. The transverse level gauge for the dummy must be horizontal otherwise the above procedure must be followed again.5. RESULTS5.1. Once the dummy has been placed in position in accordance with section 4, the H point and the true backrest rake angle under consideration are determined by the H point and the rake angle of the reference line of the trunk of the dummy.5.2. The coordinates of the H point in relation to three planes that are at right angles respectively to the true backrest rake angle must be measured for comparison with the data provided by the manufacturer of the vehicle.6. CHECKING OF THE POSITION RELATIVE TO THE R AND H POINTS AND OF THE RELATIONSHIP BETWEEN THE INTENDED ANGLE AND THE TRUE BACKREST RAKE ANGLE6.1. The results of the measurements carried out in accordance with 5.2 in respect of the H point and the true backrest rake angle are compared with the coordinates for the R point and with the intended backrest rake angle stated by the manufacturer of the vehicle.6.2. The check on the relative position of the R and H points and on the relationship between the intended angle and true backrest rake angle is considered satisfactory for the seating position under consideration if the H point as defined by its coordinates is located within a 50 mm square having a centre R and if the true backrest rake angle does not diverge by more than 5° from the intended rake angle.6.2.1. If these conditions are met the R point and the intended rake angle are used for the test and, if necessary, the dummy is adjusted so that the H point coincides with the R point and the true backrest rake angle coincides with the intended angle.6.3. If the H point or the true rake angle do not meet the requirements set out in 6.2 the H point or the true rake angle are determined twice more (three times altogether). If the results obtained during two of these three operations meet the requirements the result of the test is considered satisfactory.6.4. If the results of at least two of the three operations do not meet the requirements set out in 6.2 the result of the test is considered unsatisfactory.6.5. If the situation described in 6.4 arises or if the check cannot be carried out because the manufaturer has not provided information on the position of the R point or the intended backrest rake angle the average of the results of the three determinations may be used and be considered as applying in all cases where the R point or intended backrest rake angle is referred to in this Chapter.Appendix Figure 1 Components of the Three-Dimensional Dummy >REFERENCE TO A GRAPHIC>Figure 2 Dimensions and mass of Dummy >REFERENCE TO A GRAPHIC>ANNEX IV TRACTION DEVICE (dimensions in mm)Figure 1 >REFERENCE TO A GRAPHIC>Figure 2 >REFERENCE TO A GRAPHIC>Figure 3 >REFERENCE TO A GRAPHIC>ANNEX V Appendix 1 Information document in respect of safety-belt anchorages intended for a type of bodied three-wheel moped, tricycle or quadricycle >START OF GRAPHIC>(to be attached to the component type-approval application if this is submitted separately from the vehicle type-approval application)Order No (assigned by the applicant) ..........The application for the component type-approval of safety-belt anchorages for a type of bodied three-wheel moped, tricycle or quadricycle must contain the information set out in Annex II to Directive 92/61/EEC of 30. 6. 1992, in Part A, sections:0.1,0.2,0.4 to 0.6;and in Part C, sections:2.7 to 2.7.5.2,2.10 to 2.10.5.>END OF GRAPHIC>Appendix 2 Component type-approval certificate in respect of safety-belt anchorages intended for a type of bodied three-wheel moped, tricycle or quadricycle >START OF GRAPHIC>Name of administrationReport No: ..........by technical service: ..........Date: ..........Component type-approval No: ..........Extension No: ..........1.

All the tests on the windscreen washer described in 3.2.1 to 3.2.3 must be carried out on the same device.Appendix 1 Procedure to be followed in order to determine the fields of vision on the windscreens of bodied three-wheel mopeds, tricycles and quadricycles in relation to the V points1. POSITIONS OF THE V POINTS1.1. Tables I and II give the position of the V points in relation to the R point as emerging from their X, Y and Z coordinates within the three-dimensional reference system.1.2. Table I indicates the base coordinates for a designated backrest rake angle of 25°. The positive direction of the coordinates is shown in figure 1.>TABLE>1.3. Correction to be made to the intended backrest rake angles other than 25°.1.3.1. Table II gives the additional corrections to be made to coordinates Ä X for each V pont when the intended backrest rake angles differs from 25°. The positive direction of the coordinates is given in Figure 1.>TABLE>2. FIELDS OF VISION2.1. Two fields of vision are determined from the V points.2.2. Field of vision A is the area on the outer protruding surface of the windscreen which is bounded by the four following planes emanating forwards from the V points (see Figure 1):- a vertical plane passing through V1 and V2 and forming an angle of 18° to the left with the X axis;- a plane parallel to the Y axis passing through V1 and forming an angle of 3° upwards with the X axis;- a plane parallel to the Y axis passing through V2 and forming an angle of 1° downwards with the X axis;- a vertical plane passing through V1 and V2 and forming an angle of 20° to the right with the X axis.Figure 1 Field of Vision A >REFERENCE TO A GRAPHIC>Appendix 2 Mixture for testing windscreen wipers and washersThe test mixture referred to in sections 3.1.8 and 3.2.4.2 comprises, by volume, 92.5 % of water (having a hardness of less than 205 g/1 000 kg following evaporation), 5 % of saturated aqueous salt (sodium chloride) and 2.5 % by mass of dust the composition of which is shown in Tables I and II.>TABLE>>TABLE>Appendix 3 Information document in respect of the windscreen wiper for a type of bodied three-wheel moped, tricycle or quadricycle >START OF GRAPHIC>(to be attached to the component type-approval application where this is submitted separately from the vehicle type-approval application)Order No (assigned by the applicant) ..........The component type-approval application in respect of the windscreen wiper for a type of bodied three-wheel moped, tricycle or quadricycle must contain the following information:1.
