   Where advantage is taken of this derogation, the arm shall be indelibly marked with the symbol 
   and the type-approval certificate shall be endorsed to this effect.
   6.1.3.2.   Impact test
   The test according to this paragraph is not to be carried out for devices integrated in the bodywork of the vehicle and providing a frontal deflecting area of an angle not more than 45° measured in relation to the longitudinal median plane of the vehicle, or devices not protruding more than 100 mm measured beyond the circumscribing bodywork of the vehicle according to Regulation No 26.
   6.1.3.2.1.   Description of the test rig
   The test rig consists of a pendulum capable of swinging about two horizontal axes at right angles to each other, one of which is perpendicular to the plane containing the ‘release’ trajectory of the pendulum.
   The end of the pendulum comprises a hammer formed by a rigid sphere with a diameter of 165 ± 1 mm having a 5 mm thick rubber covering of Shore A hardness 50.
   A device is provided which permits determination of the maximum angle assumed by the arm in the plane of release.
   A support firmly fixed to the structure of the pendulum serves to hold the specimens in compliance with the impact requirements specified in paragraph 6.1.3.2.2.6.
   Figure 1 below gives the dimensions (in mm) of the test rig and the special design specifications:
   
      Figure 1
   
   
      
   6.1.3.2.1.2.   The centre of percussion of the pendulum coincides with the centre of the sphere, which forms the hammer. It is at a distance l from the axis of oscillation in the release plane, which is equal to 1 m ± 5 mm. The reduced mass of the pendulum is mo = 6,8 ±0,05 kilograms. The relationship of mo to the total mass m of the pendulum and to the distance d between the centre of gravity of the pendulum and its axis of rotation is expressed in the equation:
   
      
   6.1.3.2.2.   Description of the test
   6.1.3.2.2.1.   The procedure used to clamp the mirror to the support shall be that recommended by the manufacturer of the device or, where appropriate, by the vehicle manufacturer.
   Positioning of the mirror for the test:
   6.1.3.2.2.2.1.   Mirrors shall be positioned on the pendulum impact rig in such a way that the axes which are horizontal and vertical when the mirror is installed on a vehicle in accordance with the applicant’s mounting instructions are in a similar position;
   6.1.3.2.2.2.2.   When a mirror is adjustable with respect to the base, the test position shall be that in which any pivoting device is least likely to operate, within the limits of adjustment provided by the applicant;
   6.1.3.2.2.2.3.   When the mirror has a device for adjusting its distance from the base, the device must be set in the position in which the distance between the housing and the base is shortest;
   6.1.3.2.2.2.4.   When the reflecting surface is mobile in the housing, it shall be so adjusted that the upper corner, which is furthest from the vehicle, is in the position of greatest projection relative to the housing.
   6.1.3.2.2.3.   Except in the case of test 2 for interior mirrors (see paragraph 6.1.3.2.2.6.1), when the pendulum is in a vertical position the horizontal and longitudinal vertical planes passing through the centre of the hammer shall pass through the centre of the reflecting surface as defined in paragraph 2.1.1.10. The longitudinal direction of oscillation of the pendulum shall be parallel to the longitudinal median plane of the vehicle.
   6.1.3.2.2.4.   When, under the conditions governing adjustment laid down in paragraphs 6.1.3.2.2.1 and 6.1.3.2.2.2 parts of the mirror limit the return of the hammer, the point of impact must be displaced in a direction perpendicular to the axis of rotation or pivoting in question.
   The displacement must be no greater than is strictly necessary for the execution of the test; it must be limited in such a way that:
   
               —
            
            
               either the sphere delimiting the hammer remains at least tangential to the cylinder as defined in paragraph 6.1.1.5;
            
         
               —
            
            
               or the point of contact with the hammer is located at least 10 mm from the periphery of the reflecting surface.
            
         6.1.3.2.2.5.   The test consists in allowing the hammer to fall from a height corresponding to a pendulum angle of 60° from the vertical so that the hammer strikes the mirror at the moment when the pendulum reaches the vertical position.
   The mirrors are subjected to impact under the following different conditions:
   6.1.3.2.2.6.1.   Interior mirrors
   
               —
            
            
               Test 1: The points of impact shall be as defined in paragraph 6.1.3.2.2.3. The impact must be such that the hammer strikes the mirror on the reflecting surface side.
            
         
               —
            
            
               Test 2: Point of impact on the edge of the protective housing, such that the impact produced makes an angle of 45° with the plane of the reflecting surface and is situated in the horizontal plane passing through the centre of that surface. The impact must occur on the reflecting surface side.
            
         6.1.3.2.2.6.2.   Exterior mirrors
   
               —
            
            
               Test 1: The point of impact shall be as defined in paragraph 6.1.3.2.2.3 or 6.1.3.2.2.4. The impact must be such that the hammer strikes the mirror on the reflecting surface side.
            
         
               —
            
            
               Test 2: The point of impact shall be as defined in paragraph 6.1.3.2.2.3 or 6.1.3.2.2.4. The impact must be such that the hammer strikes the mirror on the side opposite to the reflecting surface.
            
         Where Class II or III rear-view mirrors are fixed to the same mounting as Class IV rear-view mirrors, the above-mentioned tests shall be executed on the lower mirror. Nevertheless, the technical service responsible for testing may repeat one or both of these tests on the upper mirror if this is less than 2 m from the ground.
   6.1.3.2.3.   Bending test on the protective housing attached to the stem (Class VII)
   6.1.3.2.3.1.   Description of test
   The 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
   
   
      
   6.1.3.2.3.2.   The test loading shall be 25 kilograms and shall be maintained for one minute.
   6.1.3.3.   Results of the tests
   In the tests described in paragraph 6.1.3.2, the pendulum must continue to swing after impact in such a way that the projection of the position assumed by the arm on the plane of release makes an angle of at least 20° with the vertical. The accuracy of measurement of the angle shall be within ± 1°.
   6.1.3.3.1.1.   This requirement is not applicable to mirrors stuck to the windscreen, in respect of which the requirement stipulated in paragraph 6.1.3.3.2 shall apply after the test.
   6.1.3.3.1.2.   The required angle to the vertical is reduced from 20° to 10° for all Class II and Class IV rear-view mirrors and for Class III rear-view mirrors which are attached to the same mounting as Class IV mirrors.
   6.1.3.3.2.   Should the mounting of the mirror break during the tests described in paragraph 6.1.3.2 for mirrors stuck to the windscreen, the part remaining must not project beyond the base by more than 10 mm and the configuration remaining after the test must satisfy the conditions laid down in paragraph 6.1.1.3.
   The reflecting surface must not break during the tests described in paragraph 6.1.3.2. However, breakage of the reflecting surface will be allowed if one of the following conditions is fulfilled:
   6.1.3.3.3.1.   the fragments of glass still adhere to the back of the housing or to a surface firmly attached to the housing; partial separation of the glass from its backing is admissible provided that this does not exceed 2,5 mm on either side of the cracks. It is permissible for small splinters to become detached from the surface of the glass at the point of impact;
   6.1.3.3.3.2.   the reflecting surface is made of safety glass.
   6.2.   DEVICES FOR INDIRECT VISION OTHER THAN MIRRORS
   6.2.1.   GENERAL REQUIREMENTS
   6.2.1.1.   If adjustment by the user is needed, the device for indirect vision shall be adjustable without the use of tools.

               2, if there is not an interior mirror
            
         Where a single exterior rear view mirror is fitted this shall be located on the left hand side of the vehicle in those countries where the traffic drives on the right and on the right hand side of the vehicle in those countries where the traffic drives on the left.
   15.2.1.1.4.   Optional rear-view mirrors for L-category vehicles
   The fitting of an exterior rear-view mirror on the side of the vehicle opposite to that of the mandatory rear-view mirror referred to in paragraph 15.2.1.1.3, is permissible. The rear-view mirror shall meet the requirements of this Regulation.
   15.2.1.2.   The provisions of this Regulation do not apply to the surveillance mirrors defined in paragraph 2.1.1.3. Nevertheless, the exterior surveillance mirrors must be mounted at least 2 m above the ground when the vehicle is under a load corresponding to its maximum technical permissible mass.
   15.2.2.   Position
   15.2.2.1.   Mirrors must be so placed that the driver, when sitting on the driving seat in a normal driving position, has a clear view of the road to the rear, side(s) or front of the vehicle.
   15.2.2.2.   Exterior mirrors shall be visible through the side windows or through the portion of the windscreen that is swept by the windscreen wiper. Nevertheless, for design reasons, this last provision (i.e. the provisions relating the cleaned part of the windscreen) shall not apply to:
   
               (a)
            
            
               exterior mirrors on the passenger side and optional exterior mirrors on the driver side of vehicles of categories M2 and M3;
            
         
               (b)
            
            
               Class VI mirrors.
            
         15.2.2.3.   In the case of any vehicle, which is in chassis/cab form when the field of vision is measured, the minimum and maximum body widths shall be stated by the manufacturer and, if necessary, simulated by dummy headboards. All vehicles and mirror configurations taken into consideration during the tests shall be shown on the type-approval certificate for a vehicle with regard to the installation of mirrors (see Annex 4).
   15.2.2.4.   The prescribed exterior mirror on the driver's side of the vehicle must be so located that an angle of not more than 55° is formed between the vertical longitudinal median plane of the vehicle and the vertical plane passing through the centre of the mirror and through the centre of the straight line 65 mm long which joins the driver's two ocular points.
   15.2.2.5.   Mirrors must not project beyond the external bodywork of the vehicle substantially more than is necessary to comply with the requirements concerning fields of vision laid down in paragraph 15.2.4.
   15.2.2.6.   Where the lower edge of an exterior mirror is less than 2 m above the ground when the vehicle is loaded to its technically permissible maximum laden mass, this mirror must not project more than 250 mm beyond the overall width of the vehicle measured without mirrors.
   15.2.2.7.   Class V and Class VI mirrors shall be mounted on vehicles in such a way that, regardless of their position after adjustment, no part of these mirrors or their holders is less than 2 m from the ground when the vehicle is under a load corresponding to its technically permissible maximum laden mass.
   These mirrors shall not, however, be mounted on vehicles the cab height of which is such as to prevent compliance with this requirement. In this case an other device for indirect vision is not requested.
   15.2.2.8.   Subject to the requirements of paragraphs 15.2.2.5, 15.2.2.6 and 15.2.2.7, mirrors may project beyond the permissible maximum widths of vehicles.
   15.2.2.9.   All Class VII mirrors shall be attached in such a way that they remain in a stable position under normal vehicle driving conditions.

               (c)
            
            
               a longitudinal vertical plane parallel to the longitudinal vertical median plane going through the outermost side of the vehicle at the driver's side; and
            
         
               (d)
            
            
               a longitudinal vertical plane parallel to the longitudinal vertical median plane 2 000 mm outside the outermost side of the vehicle opposite to the driver's side.
            
         The front of this field of vision opposite to the driver's side may be rounded off with a radius of 2 000 mm (see figure 9).
   For the defined field of vision, see also paragraph 15.2.4.9.2.
   The provisions for front mirrors are compulsory for forward controlled (as defined in paragraph 12.5) vehicles of categories N2 > 7,5 t and N3.
   If vehicles of these categories cannot fulfil the requirements by using a front mirror or a camera/monitor device, a vision support system shall be used. In the case of a vision support system this device must be able to detect an object of 50 cm height and with a diameter of 30 cm within the field defined in figure 9.
   
      Figure 9

   15.2.4.7.1.   Exterior rear-view mirror on the driver's side
   The field of vision must be such that the driver can see at least a 2,50 m wide, flat, horizontal portion of the road, which is bounded by a plane parallel to the median longitudinal vertical plane and passing through the outermost point of the vehicle on the driver's side of the vehicle and extends from 10 m behind the driver's ocular points to the horizon (see Figure 10).
   
      Figure 10
   
   
      Field of vision of Class VII mirrors
   
   
      
   15.2.4.7.2.   Exterior rear-view mirror on the passenger's side
   The field of vision must be such that the driver can see at least a 4 m wide flat, horizontal portion of the road which is bounded by a plane parallel to the median longitudinal vertical plane passing through the outermost point of the vehicle on the passenger's side and which extends from 20 m behind the driver's ocular points to the horizon (see Figure 10).
   15.2.4.8.   In the case of mirrors consisting of several reflecting surfaces which are either of different curvature or make an angle with each other, at least one of the reflecting surfaces must provide the field of vision and have the dimensions (paragraph 6.1.2.1.2.2) specified for the class to which they belong.
   15.2.4.9.   Obstructions
   15.2.4.9.1.   Interior rear-view mirror (Class I)
   The field of vision may be reduced by the presence of headrest and devices such as, in particular, sun visors, rear windscreen wipers, heating elements and stop lamp(s) of category S3 or by components of bodywork such as window columns of rear split doors, provided that the required field of vision is reduced only partly. The degree of obstruction shall be measured with the headrests adjusted to their lowest possible position and with the sun visors folded back.
   15.2.4.9.2.   Exterior mirrors (Classes II, III, IV, V, VI and VII)
   In the fields of vision specified above, obstruction due to the bodywork and its components, such as other cab mirrors, door handles, outline marker lights, direction indicators and front and rear bumpers, as well as reflective-surface cleaning components, shall not be taken into account if they are responsible for a total obstruction of less than 10 per cent of the specified field of vision. In the case of a vehicle designed and constructed for special purposes where, due to its special features, it is not possible to meet this requirement, the obstruction of the required field of vision of a Class VI mirror caused by the special features may be more than 10 per cent but not more than necessary for its special function.
   15.2.4.10.   Test procedure
   The field of vision shall be determined by placing powerful light sources at the ocular points and examining the light reflected on the vertical monitoring screen. Other equivalent methods may be used.
   15.3.   DEVICES FOR INDIRECT VISION OTHER THAN MIRRORS
   15.3.1.   A device for indirect vision shall give such performances that a critical object can be observed within the described field of vision, taking into account the critical perception.
   15.3.2.   Obstruction of the driver’s direct view caused by the installation of a device for indirect vision shall be restricted to a minimum.
   15.3.3.   For the determination of the detection distance in case of camera-monitor devices for indirect vision, the procedure of Annex 10 shall be applied.
   15.3.4.   Installation requirements for the monitor
   The viewing direction of the monitor shall roughly be the same direction as the one for the main mirror.
   15.3.5.   Vehicles may be equipped with additional devices for indirect vision.
   15.3.6.   The provisions of this Regulation do not apply to the surveillance camera-monitor-recording devices defined in paragraph 2.1.2.13. Exterior surveillance cameras either shall be mounted at least 2 m above the ground when the vehicle is under a load corresponding to its maximum technical permissible mass, or, if their lower edge is less than 2 m from the ground, shall not project more than 50 mm beyond the overall width of the vehicle measured without this device and have a radii of curvature of not less than 2,5 mm.
   16.   MODIFICATIONS OF THE VEHICLE TYPE AND EXTENSION OF APPROVAL
   Every modification of the vehicle type shall be notified to the administrative department which approved the vehicle type. The department may then either:
   16.1.1.   Consider that the modifications made are unlikely to have an appreciable adverse effect, and that in any case the vehicle still complies with the requirements; or
   16.1.2.   Require a further test report from the technical service responsible for conducting the tests.
   16.2.   Confirmation or refusal of approval, specifying the alterations, shall be communicated to the Parties to the Agreement which apply this Regulation by means of a form conforming to the model in Annex 4 to this Regulation.

   17.2.   Every vehicle approved under this Regulation shall be so manufactured as to conform to the type approved by meeting the requirements set out in paragraph 15. above.
   18.   PENALTIES FOR NON-CONFORMITY OF PRODUCTION
   18.1.   The approval granted in respect of a vehicle type pursuant to this Regulation may be withdrawn if the requirement laid down in paragraph 17.1 above is not complied with or if the vehicle fails to pass the checks prescribed in paragraph 17.2 above.
   18.2.   If a Party to the Agreement which applies this Regulation withdraws an approval it has previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation by means of a copy of the approval form bearing at the end, in large letters, the signed and dated annotation ‘APPROVAL WITHDRAWN’.
   19.   PRODUCTION DEFINITELY DISCONTINUED
   If the holder of the approval completely ceases to manufacture a type of vehicle approved in accordance with this Regulation, he shall so inform the authority which granted the approval. Upon receiving the relevant communication, that authority shall inform thereof the other Parties to the Agreement applying this Regulation by means of a copy of the approval form bearing at the end, in large letters, the signed and dated annotation ‘PRODUCTION DISCONTINUED’.
   20.   NAMES AND ADDRESSES OF TECHNICAL SERVICES RESPONSIBLE FOR CONDUCTING APPROVAL TESTS, AND OF ADMINISTRATIVE DEPARTMENTS
   The Parties to the Agreement applying this Regulation shall communicate to the United Nations Secretariat the names and addresses of the Technical Services responsible for conducting approval tests and of the Administrative Departments which grant approval and to which forms certifying approval or refusal or extension or withdrawal of approval, issued in other countries, are to be sent.
   21.   TRANSITIONAL PROVISIONS

   21.4.   As from 26 January 2010 for vehicles of category M1 and N1 and 26 January 2007 for vehicles of other categories, Contracting Parties applying this Regulation may refuse to recognize approvals of a type of vehicle which have not been granted in accordance with the 02 series of amendments to this Regulation.
   21.5.   As from 26 January 2010 for vehicles of category M1 and N1 and from 26 January 2007 for vehicles of other categories, Contracting Parties applying this Regulation may refuse to recognize approvals of a device for indirect vision which have not been granted in accordance with the 02 series of amendments to this Regulation.
   21.6.   Approvals which were granted to rear-view mirrors of Classes I or III pursuant to this Regulation in its original form (00 series) or modified by the 01 series of amendments before the date of entry into force of this series of amendments shall remain valid.
   21.7.   The provisions of this Regulation shall not prohibit the approval of a type of vehicle with regard to the mounting of rear-view mirrors pursuant to this Regulation as modified by the 02 series of amendments, if all or part of the rear-view mirrors of Classes I or III, with which it is fitted, bear the approval mark prescribed by the original version (00 or 01series) of this Regulation.
   21.8.   Notwithstanding the provisions of paragraphs 21.3 and 21.5 above, for the purpose of replacement parts Contracting Parties applying this Regulation shall continue to grant approvals according to the 01 series of amendments to this Regulation, to devices for indirect vision for use on vehicle types which have been approved before the date mentioned in paragraph 21.2 pursuant to the 01 series of amendments of Regulation No 46, and, where applicable, subsequent extensions to these approvals.
   
      (1)  As defined in Annex 7 to the Consolidated Resolution on the Construction of Vehicles (R.E.3), (document TRANS/WP.29/78/Rev.1/Amend.2 as last amended by Amend.4).
   
      (2)  A system for indirect vision is intended to detect relevant road users. The relevancy of a road user is defined by his or her position and (potential) speed. More or less in proportion with the speed of the pedestrian-cyclist- moped driver, the dimensions of these road users increase as well. For detection purposes a moped driver (D = 0,8 m) at 40 m distance would be equal to a pedestrian (D = 0,5 m) at a distance of 25 m. Considering the speeds, the moped driver would be selected as the criterion for the detection size; for that reason an object with a size of 0,8 m shall be used for determining the detection performance.
   
      (3)  1 for Germany, 2 for France, 3 for Italy, 4 for the Netherlands, 5 for Sweden, 6 for Belgium, 7 for Hungary, 8 for the Czech Republic, 9 for Spain, 10 for Serbia, 11 for the United Kingdom, 12 for Austria, 13 for Luxembourg, 14 for Switzerland, 15 (vacant), 16 for Norway, 17 for Finland, 18 for Denmark, 19 for Romania, 20 for Poland, 21 for Portugal, 22 for the Russian Federation, 23 for Greece, 24 for Ireland, 25 for Croatia, 26 for Slovenia, 27 for Slovakia, 28 for Belarus, 29 for Estonia, 30 (vacant), 31 for Bosnia and Herzegovina, 32 for Latvia, 33 (vacant), 34 for Bulgaria, 35 (vacant), 36 for Lithuania, 37 for Turkey, 38 (vacant), 39 Azerbaijan, 40 for The former Yugoslav Republic of Macedonia, 41 (vacant), 42 for the European Community (Approvals are granted by its Member States using their respective UNECE symbol), 43 for Japan, 44 (vacant), 45 for Australia, 46 for Ukraine, 47 for Republic of South Africa, 48 for New Zealand, 49 for Cyprus, 50 for Malta and 51 for Republic of Korea.

      Arrangement of approval mark of a device for indirect vision
      (See paragraph 5.4. of the Regulation)
      
         
      The above approval mark affixed to a device for indirect vision indicates that the mirror is a rear-view mirror, of Class II, which has been approved in the Netherlands (E 4) pursuant to Regulation No 46 and under approval number 022439. The first two digits of the approval number indicate that Regulation No 46 already included the 02 series of amendments when the approval was granted.
      Note: The approval number and the additional symbol must be placed close to the circle and either above or below the ‘E’ or to the left or right of that letter. The digits of the approval number must be on the same side of the ‘E’ and point in the same direction. The additional symbol must be directly opposite the approval number. The use of Roman numerals as approval numbers should be avoided so as to prevent any confusion with other symbols.
   
   
      ANNEX 6
      TEST METHOD FOR DETERMINING REFLECTIVITY
      1.   DEFINITIONS
      CIE standard illuminate A (1): Colorimetric illuminate, respecting the full radiator at T68 = 2 855,6 K.
      1.1.2.   CIE standard source A (1): Gas-filled tungsten filament lamp operating at a correlated colour temperature of T68 = 2 855,6 K.
      1.1.3.   CIE 1931 standard colorimetric observer (1): Receptor of radiation whose colorimetric characteristics correspond to the spectral tristimulus values  (λ),  (λ),  (λ) (see table).
      1.1.4.   CIE spectral tristimulus values (1): Tristimulus values of the spectral components of an equi energy spectrum in the CIE (XYZ) system.
      1.1.5.   Photopic vision (1): Vision by the normal eye when it is adapted to levels of luminance of at least several cd/m2.
      2.   APPARATUS
      2.1.   General
      The apparatus shall consist of a light source, a holder for the test sample, a receiver unit with a photodetector and an indicating meter (see Figure 1), and means of eliminating the effects of extraneous light.
      The receiver may incorporate a light-integrating sphere to facilitate measuring the reflectance of non-flat (convex) mirrors (see Figure 2).
      2.2.   Spectral characteristics of light source and receiver
      The light source shall consist of a CIE standard source A and associated optics to provide a near-collimated light beam. A voltage stabiliser is recommended in order to maintain a fixed lamp voltage during instrument operation.
      The receiver shall have a photodetector with a spectral response proportional to the photopic luminosity function of the CIE (1931) standard colorimetric observer (see table). Any other combination of illuminate-filter-receptor giving the overall equivalent of CIE standard illuminate A and photopic vision may be used. When an integrating sphere is used in the receiver, the interior surface of the sphere shall be coated with a matt (diffusive) spectrally non-selective white coating.
      2.3.   Geometrical conditions
      The angle of the incident beam (θ) should preferably be 0,44 ± 0,09 rad (25 ± 5°) from the perpendicular to the test surface and shall not exceed the upper limit of the tolerance (i.e. 0,53 rad or 30°). The axis of the receptor shall make an angle (θ) with this perpendicular equal to that of the incident beam (see Figure 1). The incident beam upon arrival at the test surface shall have a diameter of not less than 13 mm (0,5 in.). The reflected beam shall not be wider than the sensitive area of the photodetector, shall not cover less than 50 per cent of such area, and as nearly as possible shall cover the same area segment as used during instrument calibration.
      When an integrating sphere is used in the receiver section, the sphere shall have a minimum diameter of 127 mm (5 in.). The sample and incident beam apertures in the sphere wall shall be of such a size as to admit the entire incident and reflected light beams. The photodetector shall be so located as not to receive direct light from either the incident or the reflected beam.
      2.4.   Electrical characteristics of the photodetector-indicator unit
      The photodetector output as read on the indicating meter shall be a linear function of the light intensity of the photosensitive area. Means (electrical and/or optical) shall be provided to facilitate zeroing and calibration adjustments. Such means shall not affect the linearity or the spectral characteristics of the instrument. The accuracy of the receptor indicator unit shall be within ±2 per cent of full scale, or ±10 per cent of the magnitude of the reading, whichever is the smaller.
      2.5.   Sample holder
      The mechanism shall be capable of locating the test sample so that the axes of the source arm and receptor intersect at the reflecting surface. The reflecting surface may lie within or at either face of the mirror sample, depending on whether it is a first surface, second surface or prismatic ‘flip’ type mirror.
      3.   PROCEDURE
      3.1.   Direct calibration method
      In the direct calibration method, air is used as the reference standard. This method is applicable for those instruments, which are so constructed as to permit calibration at the 100 per cent point by swinging the receiver to a position directly on the axis of the light source (see Figure 1).
      It may be desired in some cases (such as when measuring low-reflectivity surfaces) to use an intermediate calibration point (between 0 and 100 per cent on the scale) with this method. In these cases, a neutral density filter of known transmittance shall be inserted in the optical path, and the calibration control shall then be adjusted until the meter reads the percentage transmission of the neutral density filter. This filter shall be removed before reflectivity measurements are performed.
      3.2.   Indirect calibration method
      The indirect calibration method is applicable in the case of instruments with fixed source and receiver geometry. A properly calibrated and maintained reflectance standard is required. This reference standard should preferably be a flat mirror with a reflectance value as near as possible to that of the test samples.
      3.3.   Flat mirror measurement
      The reflectance of flat mirror samples can be measured on instruments employing either the direct or the indirect calibration method. The reflectance value is read directly from the indicating meter.
      3.4.   Non-flat (convex) mirror measurement
      Measurement of the reflectance of non-flat (convex) mirrors requires the use of instruments which incorporate an integrating sphere in the receiver unit (see Figure 2). If the instrument-indicating meter indicates ne divisions with a standard mirror of E per cent reflectance, then, with a mirror of unknown reflectance, nx divisions will correspond to a reflectance of X per cent, in accordance with the formula:

      ANNEX 7
      Procedure for determining the radius of curvature ‘r’ of the reflecting surface of a mirror
      1.   MEASUREMENT
      1.1.   Equipment
      A ‘spherometer’ similar to the one described in Figure 1 of this annex having the indicated distances between the tracing pin of the dial gauge and the fixed legs of the bar is used.
      1.2.   Measuring points
      1.2.1.   The principal radii of curvature shall be measured at three points situated as close as possible to positions at one-third, one-half and two-thirds of the distance along the arc of the reflecting surface passing through the centre of this surface and parallel to segment b, or of the arc passing through the centre of the reflecting surface which is perpendicular to it if this arc is the longer.
      1.2.2.   Where, owing to the size of the reflecting surface, it is impossible to obtain measurements in the directions defined in paragraph 2.1.1.6 of this Regulation, the Technical Services responsible for the tests may take measurements at the said point in two perpendicular directions as close as possible to those prescribed above.
      2.   CALCULATION OF THE RADIUS OF CURVATURE ‘r’
      ‘r’ expressed in mm is calculated from the formula:
      
         
      where:
      
                  rp1
               
               
                  =
               
               
                  the radius of curvature at the first measuring point,
               
            
                  rp2
               
               
                  =

      ANNEX 8
      Procedure for determining the ‘H’ point and the actual torso angle for seating positions in motor vehicles
      1.   PURPOSE
      The procedure described in this annex is used to establish the ‘H’ point location and the actual torso angle for one or several seating positions in a motor vehicle and to verify the relationship of measured data to design specifications given by the vehicle manufacturer (1).
      2.   DEFINITIONS
      For the purposes of this annex:
      ‘Reference data’ means one or several of the following characteristics of a seating position:
      2.1.1.   the ‘H’ point and the ‘R’ point and their relationship;
      2.1.2.   the actual torso angle and the design torso angle and their relationship.
      2.2.   ‘Three-dimensional “H” point machine’ (3-D H machine) means the device used for the determination of ‘H’ points and actual torso angles. This device is described in Appendix 1 to this annex.
      2.3.   ‘“H” point’ means the pivot centre of the torso and thigh of the 3-D H machine installed in the vehicle seat in accordance with paragraph 4 below. The ‘H’ point is located in the centre of the centreline of the device which is between the ‘H’ point sight buttons on either side of the 3-D H machine. The ‘H’ point corresponds theoretically to the ‘R’ point (for tolerances see paragraph 3.2.2 below). Once determined in accordance with the procedure described in paragraph 4, the ‘H’ point is considered fixed in relation to the seat-cushion structure and to move with it when the seat is adjusted.
      2.4.   ‘“R” point’ or ‘seating reference point’ means a design point defined by a vehicle manufacturer for each seating position and established with respect to the three-dimensional reference system;
      2.5.   ‘Torso-line’ means the centreline of the probe of the 3-D H machine with the probe in the fully rearward position.
      2.6.   ‘Actual torso angle’ means the angle measured between a vertical line through the ‘H’ point and the torso line using the back angle quadrant on the 3-D H machine. The actual torso angle corresponds theoretically to the design torso angle (for tolerances see paragraph 3.2.2 below).
      2.7.   ‘Design torso angle’ means the angle measures between a vertical line through the ‘R’ point and the torso line in a position which corresponds to the design position of the seat-back established by the vehicle manufacturer.
      2.8.   ‘Centreplane of occupant’ (C/LO) means the median plane of the 3-D H machine positioned in each designated seating position; it is represented by the co-ordinate of the ‘H’ point on the ‘Y’ axis. For individual seats, the centreplane of the seat coincides with the centreplane of the occupant. For other seats, the centreplane of the occupant is specified by the manufacturer;
      2.9.   ‘Three-dimensional reference system’ means a system as described in Appendix 2 to this annex;
      2.10.   ‘Fiducial marks’ are physical points (holes, surfaces, marks or indentations) on the vehicle body as defined by the manufacturer;
      2.11.   ‘Vehicle measuring attitude’ means the position of the vehicle as defined by the co-ordinates of fiducial marks in the three-dimensional reference system.
      3.   REQUIREMENTS
      3.1.   Data presentation
      For each seating position where reference data are required in order to demonstrate compliance with the provisions of the present Regulation, all or an appropriate selection of the following data shall be presented in the form indicated in Appendix 3 to this annex:
      3.1.1.   the co-ordinates of the ‘R’ point relative to the three-dimensional reference system;
      3.1.2.   the design torso angle;
      3.1.3.   all indications necessary to adjust the seat (if it is adjustable) to the measuring position set out in paragraph 4.3 below.
      3.2.   Relationship between measured data and design specifications
      3.2.1.   The co-ordinates of the ‘H’ point and the value of the actual torso angle obtained by the procedure set out in paragraph 4. below shall be compared, respectively, with the co-ordinates of the ‘R’ point and the value of the design torso angle indicated by the vehicle manufacturer.
      3.2.2.   The relative positions of the ‘R’ point and the ‘H’ point and the relationship between the design torso angle and the actual torso angle shall be considered satisfactory for the seating position in question if the ‘H’ point, as defined by its co-ordinates, lies within a square of 50 mm side length with horizontal and vertical sides whose diagonals intersect at the ‘R’ point, and if the actual torso angle is within 5 degree of the design of the torso angle.
      3.2.3.   If these conditions are met, the ‘R’ point and the design torso angle, shall be used to demonstrate compliance with the provisions of this Regulation.
      3.2.4.   If the ‘H’ point or the actual torso angle does not satisfy the requirements of paragraph 3.2.2 above, the ‘H’ point and the actual torso angle shall be determined twice more (three times in all). If the results of two of these three operations satisfy the requirements, the conditions of paragraph 3.2.3 above shall apply.
      3.2.5.   If the results of at least two of the three operations described in paragraph 3.2.4 above do not satisfy the requirements of paragraph 3.2.2 above, or if the verification cannot take place because the vehicle manufacturer has failed to supply information regarding the position of the ‘R’ point or regarding the design torso angle, the centroid of the three measured points or the average of the three measured angles shall be used and be regarded as applicable in all cases where the ‘R’ point or the design torso angle is referred to in this Regulation.
      4.   PROCEDURE FOR ‘H’ POINT AND ACTUAL TORSO ANGLE DETERMINATION
      4.1.   The vehicle shall be preconditioned at the manufacturer's discretion, at a temperature of 20 ± 10 °C to ensure that the seat material reaches the room temperature. If the seat to be checked has never been sat upon, a 70 to 80 kg person or device shall sit on the seat twice for one minute to flex the cushion and back. At the manufacturer's request, all seat assemblies shall remain unloaded for a minimum period of 30 min prior to installation of the 3-D H machine.
      4.2.   The vehicle shall be at the measuring attitude defined in paragraph 2.11 above.
      4.3.   The seat, if it is adjustable, shall be adjusted first to the rearmost normal driving or riding position, as indicated by the vehicle manufacturer, taking into consideration only the longitudinal adjustment of the seat, excluding seat travel used for purposes other than normal driving or riding positions. Where other modes of seat adjustment exist (vertical, angular, seat-back, etc.) these will be then adjusted to the position specified by the vehicle manufacturer. For suspension seats, the vertical position shall be rigidly fixed corresponding to a normal driving position as specified by the manufacturer.
      4.4.   The area of the seating position contacted by the 3-D H machine shall be covered by a muslin cotton, of sufficient size and appropriate texture, described as a plain cotton fabric having 18,9 threads per/cm2 and weighing 0,228 kg/m2 or knitted or non-woven fabric having equivalent characteristics.
      If test is run on a seat outside the vehicle, the floor on which the seat is placed shall have the same essential characteristics (2) as the floor of the vehicle in which the seat is intended to be used.
      4.5.   Place the seat and back assembly of the 3-D H machine so that the centreplane of the occupant (C/LO) coincides with the centreplane of the 3-D H machine. At the manufacturer's request, the 3-D H machine may be moved inboard with respect to the C/LO if the 3-D H machine is located so far outboard that the seat edge will not permit levelling of the 3-D H machine.
      4.6.   Attach the foot and lower leg assemblies to the seat pan assembly, either individually or by using the T-bar and lower leg assembly. A line through the ‘H’ point sight buttons shall be parallel to the ground and perpendicular to the longitudinal centreplane of the seat.
      Adjust the feet and leg positions of the 3-D H machine as follows:
      4.7.1.   Designated seating position: driver and outside front passenger
      4.7.1.1.   Both feet and leg assemblies shall be moved forward in such a way that the feet take up natural positions on the floor, between the operating pedals if necessary. Where possible the left foot shall be located approximately the same distance to the left of the centreplane of the 3-D H machine as the right foot is to the right. The spirit level verifying the transverse orientation of the 3-D H machine is brought to the horizontal by readjustment of the seat pan if necessary, or by adjusting the leg and foot assemblies towards the rear. The line passing through the ‘H’ point sight buttons shall be maintained perpendicular to the longitudinal centreplane of the seat.
      4.7.1.2.   If the left leg cannot be kept parallel to the right leg and the left foot cannot be supported by the structure, move the left foot until it is supported. The alignment of the sight buttons shall be maintained.
      4.7.2.   Designated seating position: outboard rear
      For rear seats or auxiliary seats, the legs are located as specified by the manufacturer. If the feet then rest on parts of the floor which are at different levels, the foot which first comes into contact with the front seat shall serve as a reference and the other foot shall be so arranged that the spirit level giving the transverse orientation of the seat of the device indicates the horizontal.
      4.7.3.   Other designated seating positions:
      The general procedure indicated in paragraph 4.7.1 above shall be followed except that the feet shall be placed as specified by the vehicle manufacturer.
      4.8.   Apply lower leg and thigh weights and level the 3-D H machine.
      Tilt the back pan forward against the forward stop and draw the 3-D H machine away from the seat-back using the T-bar. Reposition the 3-D H machine on the seat by one of the following methods:
      4.9.1.   If the 3-D H machine tends to slide rearward, use the following procedure. Allow the 3-D H machine to slide rearward until a forward horizontal restraining load on the T-bar is no longer required, i.e. until the seat pan contacts the seat-back. If necessary, reposition the lower leg;
      4.9.2.   If the 3-D H machine does not tend to slide rearward, use the following procedure. Slide the 3-D H machine rearwards by applying a horizontal rearward load to the T-bar until the seat pan contacts the seat-back (see figure 2 of Appendix 1 to this annex).
      4.10.   Apply a 100 ± 10 N load to the back and pan assembly of the 3-D H machine at the intersection of the hip angle quadrant and the T-bar housing. The direction of load application shall be maintained along a line passing by the above intersection to a point just above the thigh bar housing (see figure 2 of Appendix 1 to this Annex). Then carefully return the back pan to the seat-back. Care must be exercised throughout the remainder of the procedure to prevent the 3-D H machine from sliding forward.
      4.11.   Install the right and left buttock weights and then, alternately, the eight torso weights. Maintain the 3-D H machine level.
      4.12.   Tilt the back pan forward to release the tension on the seat-back. Rock the 3-D H machine from side to side through 10° arc (5° to each side of the vertical centreplane) for three complete cycles to release any accumulated friction between the 3-D H machine and the seat.
      During the rocking action, the T-bar of the 3-D H machine may tend to diverge from the specified horizontal and vertical alignment. The T-bar must therefore be restrained by applying an appropriate lateral load during the rocking motions. Care shall be exercised in holding the T-bar and rocking the 3-D H machine to ensure that no inadvertent exterior loads are applied in a vertical or fore-and-aft direction.
      The feet of the 3-D H machine are not to be restrained or held during this step. If the feet change position, they should be allowed to remain in that attitude for the moment.
      Carefully return the back pan to the seat-back and check the two spirit levels for zero position. If any movement of the feet has occurred during the rocking operation of the 3-D H machine, they must be repositioned as follows:
      Alternately, lift each foot off the floor the minimum necessary amount until no additional foot movement is obtained. During this lifting, the feet are to be free to rotate; and no forward or lateral loads are to be applied. When each foot is placed back in the down position, the heel is to be in contact with the structure designed for this;
      Check the lateral spirit level for zero position; if necessary, apply a lateral load to the top of the back pan sufficient to level the 3-D H machine's seat pan on the seat.
      4.13.   Holding the T-bar to prevent the 3-D H machine from sliding forward on the seat cushion, proceed as follows:
      
                  (a)
               
               
                  return the back pan to the seat back;
               
            
                  (b)
               
               
                  alternately apply and release a horizontal rearward load, not to exceed 25 N, to the back angle bar at a height approximately at the centre of the torso weights until the hip angle quadrant indicates that a stable position has been reached after load release. Care shall be exercised to ensure that no exterior downward or lateral loads are applied to the 3-D H machine. If another level adjustment of the 3-D H machine is necessary, rotate the back pan forward, re-level, and repeat the procedure from paragraph 4.12.
               
            Take all measurements:
      4.14.1.   The co-ordinates of the ‘H’ point are measured with respect to the three-dimensional reference system;
      4.14.2.   The actual torso angle is read at the back angle quadrant of the 3-D H machine with the probe in its fully rearward position.
      4.15.   If a re-run of the installation of the 3-D H machine is desired, the seat assembly should remain unloaded for a minimum period of 30 min prior to the re-run. The 3-D H machine should not be left loaded on the seat assembly longer than the time required to perform the test.
      If the seats in the same row can be regarded as similar (bench seat, identical seats, etc.) only one ‘H’ point and one ‘actual torso angle’ shall be determined for each row of seats, the 3-D H machine described in appendix 1 to this annex being seated in a place regarded as representative for the row. This place shall be:
      4.16.1.   in the case of the front row, the driver's seat;
      4.16.2.   in the case of the rear row or rows, an outer seat.
      
         (1)  In any seating position other than front seats where the ‘H’ point cannot be determined using the ‘Three-dimensional “H” point machine’ or procedures, the ‘R’ point indicated by the manufacturer may be taken as a reference at the discretion of the Competent Authority.
      
         (2)  Tilt angle, height difference with a seat mounting, surface texture, etc.

         DESCRIPTION OF THE THREE DIMENSIONAL ‘H’ POINT MACHINE (1)
         
         (3-D H machine)
         1.   Back and seat pans
         The back and seat pans are constructed of reinforced plastic and metal; they simulate the human torso and thigh and are mechanically hinged at the ‘H’ point. A quadrant is fastened to the probe hinged at the ‘H’ point to measure the actual torso angle. An adjustable thigh bar, attached to the seat pan, establishes the thigh centreline and serves as a baseline for the hip angle quadrant.
         2.   Body and leg elements
         Lower leg segments are connected to the seat pan assembly at the T-bar joining the knees, which is a lateral extension of the adjustable thigh bar. Quadrants are incorporated in the lower leg segments to measure knee angles. Shoe and foot assemblies are calibrated to measure the foot angle. Two spirit levels orient the device in space. Body element weights are placed at the corresponding centres of gravity to provide seat penetration equivalent to a 76 kg male. All joints of the 3-D H machine should be checked for free movement without encountering noticeable friction.

      2.   SECONDARY FUNCTIONAL REQUIREMENTS
      Based on the installation conditions, a determination shall be made to discover whether the entire device can still satisfy the functional requirements listed in paragraph 6.2.2 of this Regulation, especially the glare correction, the maximum and the minimum luminance of the monitor. It shall also be determined the degree to which the glare correction will be addressed and the angle at which sunlight can strike a monitor and these shall be compared to the corresponding measuring results from the system measurements. This can be either based on a CAD-generated model, a determination of the angles of light for the device when mounted on the relevant vehicle, or by carrying out relevant measurements on the relevant vehicle as described in paragraph 6.2.2.2 of this Regulation.
