ANNEX II

SPEED GOVERNOR AND PROTECTION OF DRIVE COMPONENTS, PROJECTIONS AND WHEELS

1. SPEED GOVERNOR

1.1. If a speed governor is fitted as standard by the manufacturer, it must be installed and designed in such a way that the tractor complies with Directive 74/152/EEC ( 8 ) on maximum design speed.

2. PROTECTION OF DRIVE COMPONENTS, PROJECTIONS AND WHEELS

2.1. General

2.1.1. Drive components, projections and wheels on tractors must be designed, fitted and protected in such a way as to prevent accidents to persons under normal conditions of use.

2.1.2. The requirements of point 2.1.1 are regarded as being fulfilled if the requirements set out in section 2.3 have been complied with. Solutions other than those described in section 2.3 are authorized if the manufacturer provides proof that they are at least equivalent to the requirements of section 2.3.

2.1.3. Protective devices must be firmly attached to the tractor. Firmly attached means that removal of such devices should be possible only with the aid of tools.

2.1.4. Cowls, lids and hoods, which could cause injury if they are slammed shut, must be made in such a way as to preclude their shutting accidentally (e.g. by means of safety devices or suitable mounting or design).

2.1.5. A single protective device may protect a number of dangerous points. However, if adjustment, maintenance or interference suppression devices — which can be actuated only when the engine is running — are fitted beneath a single protective device, then further protective devices must be fitted.

2.1.6. Securing devices (e.g. spring clips or flaps) — to secure quick-release mounting components (e.g. socket pins), — and such components of — protective devices which open without the aid of tools (e.g. engine cowl) must be firmly attached either to the tractor mounting or to the protective device.

2.2. Definitions

2.2.1. Protective device means a device intended to protect dangerous parts. Within the meaning of this Directive, protective devices include shields, covers or guards. 2.2.1.1. Shield means a protective device located immediately in front of a dangerous part and which, either on its own or with other parts of the machine, protects on all sides against contact with the dangerous part. 2.2.1.2. Hood or cowl means a protective device located in front of the dangerous part and which protects against contact with the dangerous part on the covered side. 2.2.1.3. Guard means a protective device which, by means of a rail, grill or similar device provides the necessary safety distance preventing contact with the dangerous part.

2.2.2. Dangerous part means any point which, owing to the arrangements or design of the fixed or movable part of a tractor, involves a risk of injury. The dangerous parts are, in particular, pinching, shearing, cutting, piercing, penetrating, snatching, entry and attack points. 2.2.2.1. Pinching point means any dangerous point where parts move in relation to each other or to fixed parts in such a way as may cause persons or certain parts of their bodies to be pinched. 2.2.2.2. Shear point means any dangerous point where parts move along each other or along other parts in such a way as may cause persons or certain parts of their bodies to be pinched or shorn. 2.2.2.3. Cutting, piercing or penetration point means any dangerous point where parts, either moving or fixed, sharp edged, pointed or blunt may injure persons or certain parts of their bodies. 2.2.2.4. Snatching point means any dangerous point where sharp-edged projections, teeth, pins, screws and bolts, grease nipples, shafts, shaft ends and other parts move in such a way that persons, certain parts of their bodies or clothing may be snatched and pulled along. 2.2.2.5. Entry or attack point means any dangerous point whose parts, by moving, narrow an aperture in which persons, certain parts of their bodies or clothes may be caught.

2.2.3. Reach means the maximum distance which can be reached by persons or certain parts of their bodies upwards, downwards, inwards, above, around or across without the aid of any object (Figure 1).

2.2.4. Safety distance means the distance corresponding to the reach or to the body dimension plus a safety margin (Figure 1).

2.2.5. Control means any device whose direct actuation enables the state or operation of the tractor or of any equipment linked to it to be altered.

2.3. Safety distances for avoiding contact with dangerous parts

2.3.1. The safety distance is measured from those points which may be reached to actuate, service and inspect the tractor, and also from ground level. Servicing and inspecting the tractor solely means work normally carried out by the driver himself in accordance with the instructions for use. In determining the safety distances the basic principle is that the tractor is in the state for which it has been designed and that no means has been used in order to reach the dangerous part. Safety distances are set out in points 2.3.2.1 to 2.3.2.5. In certain specific areas or for certain specific component parts an appropriate safety level is provided if the tractor corresponds to the requirements set out in points 2.3.2.6 to 2.3.2.14.

2.3.2. Protection of dangerous points Upwards The upward safety margin is 2 500 mm (see Figure 1) in the case of persons standing upright. Figure 1 2.3.2.2. Downwards, above The safety margin for reaching above a barrier is: a = from ground level up to the dangerous point; b = height of barrier or protective device; c = horizontal distance between dangerous point and barrier (see Figure 2). Figure 2 When reaching both downwards and above the safety distances set out in Table 1 must be maintained.



(mm) a: Distance from ground of dangerous point Height between barrier and protective device b 2 400 2 200 2 000 1 800 1 600 1 400 1 200 1 000 Horizontal distance c from dangerous point 2 400 — 100 100 100 100 100 100 100 2 200 — 250 350 400 500 500 600 600 2 000 — — 350 500 600 700 900 1 100 1 800 — — — 600 900 900 1 000 1 100 1 600 — — — 500 900 900 1 000 1 300 1 400 — — — 100 800 900 1 000 1 300 1 200 — — — — 500 900 1 000 1 400 1 000 — — — — 300 900 1 000 1 400 800 — — — — — 600 900 1 300 600 — — — — — — 500 1 200 400 — — — — — — 300 1 200 200 — — — — — — 200 1 100 2.3.2.3. Reach around The safety margin shown in Table 2 below must, at the minimum, be maintained if the part of the body concerned is not to reach a dangerous point. In applying the safety margin it is assumed that the main body joint concerned is pushed firmly against the edge of the protective device. The safety margins are not considered to have been maintained until one is satisfied that part of the body may quite definitely not advance or penetrate further. 2.3.2.4. Penetration and reach across If penetration is possible into or across openings and up to dangerous parts, the minimum safety distances set out in Tables 3 and 4 must be maintained. Parts which move in relation to one another or moving parts set alongside fixed parts are not regarded as risk factors provided they are no more than 8 mm apart. a is the smaller dimension of the aperture. b is the safety distance from danger point a is the aperture/diameter or length of side. b is the safety distance from danger point. 2.3.2.5. Safety distances at pinching points A pinching point is not considered dangerous for the part of the body shown if the safety distances are not less than those set out in Table 5, and if it is ensured that the adjacent, wider part of the body cannot be introduced. 2.3.2.6. Controls The gap between two pedals and the holes through which controls pass are not regarded as being pinching or shearing points. 2.3.2.7. Rear three-point coupling 2.3.2.7.1. Behind a plane passing through the median plane of the pivot points of the lifting rods in a three-point coupling system a minimum safety margin of 25 mm must be maintained between the moving parts for each point or of the lifting device's travel — but not for the extreme upper andlower positions 0,1 n, together with a distance of 25 mm or a minimum angle of 30° for the parts in shear which cause a change in angularity (see Figure 3). Travel n′, reduced by 0,1 n at both its upper and lower ends is defined as follows (see Figure 4). ►M2 Meta l-konnessjonijiet l-aktar baxxi huma direttament attivati bil-mekkaniżmu ta' l-irfigħ, il-pjan ta' referenza huwa determinat bil-pjan medjan trasvers vertikali ta' dawk il-konnessjonijiet: ◄ ▼M2 Figura 3 ▼B Figure 4 2.3.2.7.2. For travel n of the hydraulic lifting unit, lower position A of the coupling point of the lower link is limited by dimension 14 in accordance with ISO Standard 730, Part 1, while upper position B is limited by the maximum hydraulic travel. Travel n′ corresponds to travel n reduced upwards and downwards by 0,1 n, and constitutes the vertical distance between A′ and B′. 2.3.2.7.3. Moreover, within travel n′ a minimum safety margin of 25 mm in relation to the adjacent parts must be maintained around the profile of the lifting rods. 2.3.2.7.4. If, in the case of a three-point coupling, coupling devices are used which do not require the presence of an operator between the tractor and the implement carried (for example, in the case of a quick coupling), the provisions of point 2.3.2.7.3 do not apply. 2.3.2.7.5. The operating manual should contain specific information on the dangerous points located at the front of the plane defined in the first sentence of point 2.3.2.7.1. 2.3.2.8. Front three-point coupling 2.3.2.8.1. At each point of the lifting unit's travel n — but not for the extreme upper and lower reaches 0,1 n — a minimum safety margin of 25 mm must be maintained between the moving parts together with a minimum angle of 30° or a safety margin of 25 mm in the case of the change of angularity caused by the parts in shear with each other. Travel n′ reduced by 0,1 n at both its upper and lower ends, is defined as follows (see also Figure 4). 2.3.2.8.2. For travel n of the hydraulic lifting unit, extreme lower position A of the coupling point of the lower link is limited by dimension 14 in accordance with ISO Standard 8759, Part 2, while extreme upper position B is limited by the maximum hydraulic travel. Traven n′ reduced upwards and downwards by 0,1 n and the vertical distance between A′ and B′. 2.3.2.8.3. If, for the lower links of a front three-point coupling, coupling devices (such as a rapid-action coupling) are used which do not require the presence of a person between the tractor and the implement attached during coupling, the requirements under 2.3.2.8.1 do not apply within the reach of a radius of 250 mm from the points at which the lower links are coupled to the tractor. However, a minimum safety margin of 25 mm from neighbouring parts within the defined travel n′ must in any case be maintained around the outside of the travel rods/cylinders. 2.3.2.9. Driving seat and environment When he is in a sitting position, all pinching of shearing points must be out of range of the driver's hands or feet. This requirement is considered to have been met if the following conditions are fulfilled: 2.3.2.9.1. The driver's seat is at the mid-point in its longitudinal and vertical adjustment range. The driver's reach limit is divided into zones A and B. A central spherical point of these zones is 60 mm in front of and 580 mm above the seat reference point (see Figure 5). Zone A consists of a sphere having a diameter of 550 mm while zone B is located between that sphere and a sphere having a radius of 1 000 mm. Figure 5 2.3.2.9.2. A safety distance of 120 mm in zone A and 25 mm in zone B is maintained near the pinching and shearing points, whilst a minimum angle of 30° is maintained in the case of shearing parts causing a change in angularity. 2.3.2.9.3. In zone A, only the pinching and shearing points caused by parts set in motion by an outside energy source must be taken into account. 2.3.2.9.4. If a dangerous point is due to the presence of structural parts adjacent to the seat, a safety distance of a least 25 mm is maintained between that structural part and the seat. There is no dangerous point between the seat backrest and the adjacent structural parts located behind that backrest if the adjacent structural parts are smooth and the seat backrest itself is rounded in the surrounding area and has no sharp points. 2.3.2.10. Passenger seat (if any) 2.3.2.10.1. If parts may constitute a danger for the feet, provision must be made for protective devices within a hemispherical radius of 800 mm starting from the forward edge of the seat cushion and pointing downwards. 2.3.2.10.2. As described in section 2.3.2.9 (see Figure 6) the dangerous points in zones A and B must be protected within a sphere whose centre is 670 mm above the centre of the front edge of the passenger seat. Figure 6 2.3.2.11. Narrow-track tractors (tractors with a track as defined in the second indent of Article 1 of Directive 87/402/EEC). 2.3.2.11.1. In the case of narrow-track tractors, the requirements of section 2.3.2.9 do not apply to the zone situated below a plane inclined at 45° to the rear and transverse to the direction of travel, and passing through a point located 230 mm behind the seat index point (see Figure 7). If there are any dangerous points in this zone, corresponding warnings must be affixed to the tractor. Figure 7 2.3.2.11.2. Sections II.1 and II.2 of Annex I to Directive 80/720/EEC apply to access to the driver's seat. 2.3.2.11.3. Section I.6 of Annex I to Directive 80/720/EEC applies to control devices. 2.3.2.11.4. In front of a reference plane which passes at right angles to the longitudinal axis of the vehicle and through the centre of the load-free pedal (clutch and/or service brake), very hot exhaust components must be protected if located within 300 mm in the upper zone (700 mm above ground level) and within 150 mm in the lower zone (see Figure 8). Laterally, the area to be protected is limited by the external outline of the tractor and the external outline of the exhaust system. Very hot exhaust system components passing beneath the entry step must be covered in their vertical projection or otherwise thermally protected. Figure 8 2.3.2.12. Layout and marking of flexible hydraulic hoses 2.3.2.12.1. Flexible hydraulic hoses must be arranged in such a way as to prevent mechanical and thermal damage 2.3.2.12.2. Flexible hydraulic hoses must be clearly identifiable and indelibly marked with the following information: — the flexible hose manufacturer's mark, — manufacturing date (year and month of manufacture), — maximum permissible dynamic excess pressure in operation. 2.3.2.12.3. Flexible hydraulic hoses in the vicinity of the driver's or the passenger's seat must be arranged or protected in such a way that in the event of their failure there can be no danger to any person. 2.3.2.13. Steering and swing axle Parts moving in relation to each other or to fixed parts must be protected if they lie within the zone defined in points 2.3.2.9 and 2.3.2.10. When articulated steering is fitted, there must be indelible and clear markings within the articulation range on both sides of the tractor, indicating by means of an illustrative sign or in words that remaining within the unprotected range of articulation is not permitted. The corresponding indications must be included in the operating manual. 2.3.2.14. Transmission shafts fixed on the tractor Transmission shafts (for example, for four-wheel drive which can only rotate while the tractor is in motion, must be protected if they are located within the zone defined in sections 2.3.2.9 and 2.3.2.10. 2.3.2.15. Clearance zone around the drive wheels 2.3.2.15.1. The clearance zones of the wheel guards must meet the following requirements. 2.3.2.15.2. Clearance zone means the space which must remain clear around the tyres of the drive wheels in relation to the adjacent parts of the vehicle. The clearance zone of the drive wheels, when fitted with largest-size tyres, must correspond to the dimensions set out in the following Figure 9 and Table 6. Figure 9

2.4. Method of determining the seat index point

2.4.1. General

The method and device used in defining the index point for any type of upholstered seat are described below.

2.4.2. Definitions

Seat index point (SIP):

Point situated in the vertical median longitudinal plane of the SIP locating device represented in Figure 10 which is placed on the driving seat in accordance with points 2.4.4 and 2.4.6.

The seat index point is established in relation to the vehicle and does not move as a function of the seat adjustments and/or oscillations.

2.4.3. Device for determining the seat index point (SIP)

The device for determining the SIP must be as shown in Figure 10. The mass of that device is 6 ± 1 kg and its underside must be flat and polished.

2.4.4. Seat setting for determination of index point (SIP)

Where a seat and its suspension can be regulated, the seat is regulated as follows before the index point is determined:

(a) all of the adjustments — back/forth, height and rake — must be in their mid-position. If this is not the case, the closest adjustment either above or below the mid-position should be used;

(b) adjustable suspension must be adjusted in such a way that the suspension is at mid-travel with the locating device in position and loaded. The suspension may be locked mechanically in that position while the index point (SIP) is determined;

(c) non-adjustable suspension may be locked in the vertical position that is achieved with the locating device in place and loaded;

(d) if the adjustments mentioned above conflict with the manufacturer's specific instructions, these must be followed in such a way as to obtain the setting recommended for a 75-kg driver.

NB: A 75-kg driver offers an approximation of the locating device in position on the seat and loaded with a mass of 65 kg.

2.4.5. Determination of the three reference axes x′, y′, and z′ for the SIP

The coordinates must be established as follows:

(a) location, on one side of the seat mounting, of the attachment hole that is in the most rear position;

(b) if the axis of this hole is parallel to the pivot axis defined on the device, it is taken as axis y′, (pointing from left to right in relation to a seated driver — see Figure 11);

(c) if the axis of this hole is parallel to the vertical plane passing through the centre line of the seat, the straight line is taken as axis y′ which runs parallel to the pivot axis referred to and passes through the point of intersection between the supporting plane of the seat and the hole axis referred to above (see Figure 12).

(d) in all other cases, axis y′ is established in accordance with the parameters relating to the seat being measured;

(e) axes x′ and z′ are defined as intersections of the horizontal and vertical planes passing through y′ with the vertical plane through the seat centre line. Axes x′ and z′ point forwards and upwards (see Figures 11 and 12).

2.4.6. Method of determining the seat index point (SIP)

The seat index point (SIP) is determined by using the device shown in Figure 10 and by proceeding in the following manner:

(a) the seat is covered with a piece of cloth in order to facilitate correct positioning of the device;

(b) the device is positioned on the seat cushion (without additional mass) by pushing it rearwards against the backrest;

(c) masses are added to bring the total mass of the device from 6 ± 1 kg to 26 ± 1 kg. The centre of vertical force must be 40 mm ahead of the seat index point mark on the horizontal part of the device (see Figure 10);

(d) a horizontal force of about 100 N is applied twice to the device on the seat index point, as set out in figure 10;

(e) other masses are added to bring the total mass of the device from 26 ± 1 kg to 65 ± 1 kg. The centre of the vertical force of the masses added must be 40 mm ahead of the seat index point mark on the horizontal part of the device (see Figure 10);

(f) on both sides of the seat in two vertical planes, equidistant from the median longitudinal line of the seat, the coordinates, as defined in point 2.4.5, of the intersections of those planes on the axis of the seat index point marked by the device must be measured to ± 1 mm. The arithmetical mean values of the measurements taken in the two planes are recorded as SIP coordinates;

(g) the conditions resulting from the method of determination, and which diverge from the procedure set out in this Annex, or which may be the source of errors as regards their results, may be noted, as may their causes.

Glazing ta' plastik riġidu huwa permess għal applikazzjonijiet li mhumiex marbuta mal-windskrin kif approvati fid-Direttiva tal-Kunsill 92/22/KEE ( 9 ) jew fir-Regolament NU-ECE nru 43, l-Anness 14. ▼B

2. DEFINITIONS

For the purposes of this Directive:

2.1. toughened-glass pane means a glass pane consisting of a single layer of glass which has been subjected to special treatment to increase its mechanical strength and condition its fragmentations after shattering;

2.2. laminated-glass pane means a glass pane consisting of two or more layers of glass held together by one or more interlayers of plastic material; it may be: 2.2.1. ordinary, where none of the layers of glass of which it is composed have been treated, or 2.2.2. treated, where at least one of the layers of glass of which it is composed has been specially treated to increase its mechanical strength and to condition its fragmentation after shattering;

2.3. safety glazing coated with plastic material means a glass pane as defined in point 2.1 or 2.2 with a layer of plastic material on its inner surface;

2.4. glass-plastic safety glazing means a pane of laminated glass having one layer of glass and one or more layers of plastic material at least one of which acts as interlayer. The plastic layers shall be on the inner face when the glazing is fitted on the tractor;

2.5. group of windscreens means a group comprising windscreens of differing sizes and shapes subjected to an examination of their mechanical properties, their mode of fragmentation and their behaviour in environmental resistance tests; 2.5.1. flat windscreen means a windscreen exhibiting no nominal curvature resulting in a height of segment exceeding 10 mm per linear metre; 2.5.2. curved windscreen means a windscreen exhibiting nominal curvature resulting in a height of segment exceeding 10 mm per linear metre;

2.6. double window means a set of two panes installed separately in the same opening on the tractor;

2.7. double glazing means a unit composed of two panes permanently assembled in the factory and separated by a uniform gap; 2.7.1. symmetrical double glazing means double glazing in which the two constituent panes are of the same type (toughened or laminated glass, etc.), and exhibit identical principal and secondary characteristics; 2.7.2. asymmetrical double glazing means double glazing in which the two constituent panes are of a different type (toughened or laminated glass, etc.) or exhibit different principal and/or secondary characteristics;

2.8. principal characteristic means a characteristic which appreciably modifies the optical and/or mechanical properties of a pane of glass in a way not without significance to the function which the glass pane is to perform in a tractor. This term also covers the trade name or mark;

2.9. secondary characteristic means a characteristic capable of modifying the optical and/or mechanical properties of a pane of glass in a way which is of significance to the function which the glass pane is intended to perform in a tractor. The extent of such modification is assessed in relation to the indices of difficulty;

2.10. indices of difficulty covers a two-stage grading system applying to the variations observed in practice in each secondary characteristic. A change from index 1 to index 2 indicates the need for additional tests;

2.11. developed area of a windscreen means the minimum rectangular area of glass from which a windscreen can be manufactured;

2.12. rake angle of a windscreen means the angle included between a vertical line and a straight line passing through the top and bottom extremities of the windscreen, both lines lying in a vertical plane along the longitudinal axis of the tractor. 2.12.1. Measurement of the rake angle is performed on an unladen tractor standing on level ground. 2.12.2. Tractors equipped with hydropneumatic, hydraulic or pneumatic suspension or with a device for automatic adjustment of ground clearance according to load are tested in the normal running conditions specified by the manufacturer;

2.13. height of segment, h means the maximum distance, measured at right angles approximately to the glass pane, separating the inner surface of the pane from a pane passing through the ends of the pane, (see Annex III N, Figure 1);

Although a change in the principal characteristics implies that the product is of a new type, it is recognized that in certain cases a change in shape and dimension does not necessarily require a complete set of tests to be carried out. For certain of the tests prescribed in the individual Annexes, glass panes may be grouped together if it is evident that they have similar principal characteristics. 2.14.2. Glass panes exhibiting differences only as regards their secondary characteristics may be deemed to be of the same type; certain tests may, however, be carried out on samples of such panes if the performance of those tests is explicitly stipulated in the test conditions;

2.15. curvature, r means the approximate value of the smallest radius of arc of the windscreen as measured in the area of maximum curvature.

3. APPLICATION FOR COMPONENT TYPE-APPROVAL

The exit port of the sphere is provided with either a light trap or a reflectance standard, according to the procedure as described in point 4.4.3 below. The light trap absorbs all the light when no test piece is inserted in the light beam. The axis of the light beam must pass through the centre of the entrance and exit ports. The diameter, b, of the light-exit port must be equal to 2a · tan 4°, where a is the diameter of the sphere. The photoelectric cell must be mounted in such a way that it cannot be reached by light coming directly from the entrance port or from the reflectance standard. The surfaces of the interior of the integrating sphere and the reflectance standard must be of substantially equal reflectance and matt and non-selective. The output of the photoelectric cell must be linear within ± 2 % over the range of luminous intensities used. The design of the instrument must be such that there is no galvanometer deflection when the sphere is dark. The whole apparatus must be checked at regular intervals by means of calibration standards of defined haze. If haze measurements are made using equipment or methods differing from those defined above, the results must be corrected, if necessary, to bring them into agreement with those obtained by the apparatus described above.

4.4.1. Immediately before and after the abrasion, clean the test pieces in the following manner: (a) wipe with a linen cloth under clean running water; (b) rinse with distilled or demineralized water; (c) blow dry with oxygen or nitrogen; (d) remove possible traces of water by dabbing softly with a damp linen cloth. If necessary, dry by pressing lightly between two linen cloths. Any treatment with ultrasonic equipment must be avoided. After cleaning, the test pieces must be handled only by their edges and stored to prevent damage to, or contamination of, their surfaces.

4.4.2. Condition the test pieces for a minimum time of 48 hours at a temperature of 20 ± 5 °C and a relative humidity of 60 ± 20 %.

4.4.3. Immediately place the test piece against the entrance port of the integrating sphere. The angle between the normal (perpendicular) to the surface of the test piece and the axis of the beam must not exceed 8°. Take four readings as indicated in the following table:

Calculate the total transmittance Tt = T2/T1. Calculate the diffuse transmittance Td as follows: Calculate the percentage haze, or light, or both, scattered, as follows:m Measure the initial haze of the test piece at a minimum of four equally spaced points in the unabraded area in accordance with the formula above. Average the results for each test piece. In lieu of the four measurements, an average value may be obtained by rotating the piece uniformly at 3 rev/sec or more. For each safety-glass pane, carry out three tests with the same kind. Use the haze as a measure of the subsurface abrasion, after the test piece has been subjected to the abrasion test. Measure the light scattered by the abraded track at a minimum of four equally spaced points along the track in accordance with the formula above. Average the results for each test piece. In lieu of the four measurements, an average value may be obtained by rotating the piece uniformly at 3 rev/sec or more.

5. HIGH-TEMPERATURE TEST

5.1. Procedure

Heat to 100 °C three test samples or three test pieces of at least 300 mm × 300 mm taken by the laboratory from three windscreens or three glass panes other than windscreens, as appropriate, one of whose dimensions corresponds to the upper edge of the pane.

Maintain this temperature for a period of two hours, then allow the test sample(s) to cool to room temperature. If the safety-glass pane has both external surfaces of inorganic material, the test may be carried out by immersing the test sample vertically in boiling water for the specified period of time, care being taken to avoid undue thermal shock. If specimens are cut from windscreens, one edge of each such test specimen shall be part of an edge of the windscreen.

5.3.2. A set of test pieces or samples submitted for component type-approval are considered satisfactory from the point of view of the high-temperature resistance test if either of the following conditions is fulfilled: 5.3.2.1. all the tests give a satisfactory result, or 5.3.2.2. one test having given an unsatisfactory result, a further series of tests carried out on a new set of test pieces or samples give satisfactory results.

6. RESISTANCE-TO-RADIATION TEST

6.1. Test method

6.1.1. Apparatus

6.1.1.1. Radiation source consisting of a medium-pressure mercury-vapour arc lamp with a tubular quartz bulb of ozone-free type; the bulb axis is vertical. The nominal dimensions of the lamp are 360 mm in length by 9,5 mm in diameter. The arc length is 300 ± 4 mm. The lamp must be operated at 750 ± 50 W. Any other source of radiation which produces the same effects as the lamp specified above may be used. To check that the effects of another source are the same, a comparison is made by measuring the amount of energy emitted within a wavelength range of 300 to 450 mm, all other wavelengths being removed by the use of suitable filters. The alternative source is then used with these filters. In the case of safety-glass panes for which there is no satisfactory correlation between this test and the conditions of use it will be necessary to review the test conditions.

6.1.1.2. Power supply transformer and capacitor capable of supplying to the lamp (6.1.1.1) a starting peak-voltage of 1 100 V minimum and an operating voltage of 500 ± 50 V.

6.1.1.3. Device for mounting and rotating the test specimens at 1 to 5 rev/min about the centrally located radiation source in order to ensure even exposure.

6.1.2. Test pieces

6.1.2.1. The size of the test pieces is 76 mm × 300 mm.

6.1.2.2. The test pieces are cut by the laboratory from the upper part of the panes in such a way that: — in the case of glass panes other than windscreens the upper edge of the test pieces coincides with the upper edge of the panes, — in the case of windscreens the upper edge of the test pieces coincides with the upper limit of the zone in which regular transmittance is to be checked and determined in accordance with point 9.1.2.2 of this Annex.

6.1.3. Procedure

Check the regular light transmittance, determined in accordance with points 9.1.1 to 9.1.2 of this Annex, of three test samples before exposure. Protect a portion of each sample from the radiation, and then place the sample in the test apparatus 230 mm from and parallel lengthwise to the lamp axis. Maintain the temperature of the samples at 45 ± 5 °C throughout the test. That face of eachtest sample which would constitute a grazed exterior part of the tractor must face the lamp. For the type of lamp specified in point 6.1.1.1 the exposure time is 100 hours. After exposure, measure the regular light transmittance again in the exposed area of each sample.

6.1.4. Each test piece or sample (three in total) is subjected, in accordance with the procedure above, to radiation such that the radiation on each point of the test piece or sample produces on the interlayer used the same effect as that which would be produced by solar radiation of 1 400 W/m2 for 100 hours.

6.2. Indices of difficulty of the secondary characteristics

The test piece or sample may however show a slight coloration after irradiation when examined against a white background, but no other defect may be apparent.

6.3.2. A set of test pieces or samples submitted for component type-approval is considered satisfactory from the point of view of the resistance to radiation test if one of the following conditions is fulfilled: 6.3.2.1. all tests give a satisfactory result, or 6.3.2.2. one test having given an unsatisfactory result, a further series of tests carried out on a new set of test pieces or samples give satisfactory results.

7. RESISTANCE-TO-HUMIDITY TEST

7.1. Procedure

Keep three test samples or three test pieces at least 300 mm × 300 mm square vertically for two weeks in a closed container in which the temperature is maintained at 50 ± 2 °C and the relative humidity at 95 % ± 4 % ( 17 ).

Safety-glass panes are deemed to be satisfactory from the point of view of resistance to humidity if no significant change is observed more than 10 mm from the uncut edges or more than 15 mm from the cut edges, following a stay of two hours in the ambient atmosphere by ordinary and treated laminated glass, and of 48 hours in the ambient atmosphere by plastic-coated glass panes and plastic glazing.

7.3.2. A set of test pieces or samples submitted for component type-approval is considered satisfactory from the point of view of the resistance to humidity test if one of the following conditions is fulfilled: 7.3.2.1. all the tests give a satisfactory result; 7.3.2.2. one test having given an unsatisfactory result, a further series of tests carried out on a new set of samples give satisfactory results.

8. TESTING OF RESISTANCE TO CHANGES IN TEMPERATURE

8.1. Test method

Two 300 × 300 mm test pieces are placed in an enclosed chamber for six hours at a temperature of - 40 ± 5 °C; they are then placed in the ambient air at a temperature of 23 ± 2 °C for an hour, or until the test piece has reached a stable temperature. They are then placed in an air flow at a temperature of 72 ± 2 °C for three hours. The test pieces are then examined after they have been returned to the ambient air at 23 ± 2 °C and cooled to that temperature.

8.3. Interpretation of results

The test of resistance to changes in temperature is considered to have given a positive result if the test pieces display no cracking, opacification, exfoliation or other obvious deterioration.

9. OPTICAL QUALITIES

9.1. Light transmission test

9.1.1. Apparatus

9.1.1.1. Light source consisting of an incandescent lamp having its filament contained within a parallelepiped measuring 1,5 mm × 1,5 mm × 3 mm. The voltage at the lamp filament must be such that the colour temperature is 2 856 K ± 50 K. This voltage is stabilized within ± . The instrument used to check the voltage must be of appropriate accuracy.

9.1.1.2. Optical system consisting of a lens with a focal length of at least 500 mm and corrected for chromatic aberrations. The full aperture of the lens must not exceed f/20. The distance between the lens and the light source must be so adjusted as to obtain a light beam which is substantially parallel. A diaphragm is inserted to limit the diameter of the light beam to 7 ± 1 mm. This diaphragm is situated at a distance of 100 ± 50 mm from the lens on the side remote from the light source. The point of measurement is taken at the centre of the light beam.

9.1.1.3. Measuring equipment. The receiver must have a relative spectral sensitivity in substantial agreement with the relative spectral luminous efficiency for the ICI ( 18 ) standard photometric observer for photopic vision. The sensitive surface of the receiver is covered with a diffusing medium and must have at least twice the cross-section of the light beam emitted by the optical system. If an integrating sphere is used, the aperture of the sphere must have a cross-sectional area at least twice that of the parallel portion of the beam. The linearity of the receiver and the associated indicated instrument must be better than 2 % of the effective part of the scale.

9.1.2. Procedure

So adjust the instrument indicating the response of the receiver that it indicates 100 divisions when the safety-glass pane is not inserted in the light path. When no light is falling on the receiver, the instrument must read zero.

Place the safety-glass pane at a distance from the receiver equal to approximately five times the diameter of the receiver. Insert the safety-glass pane between the diaphragm and the receiver and adjust its orientation in such a way that the angle of incidence of the light beam is equal to 0° ± 5°. The regular transmittance is measured on the safety-glass pane, and for every point measured the number of divisions, n, shown on the indicating instrument, are read. The regular transmittance τr is equal to n/100.

9.1.2.1. In the case of windscreens, alternative test methods may be applied using either a test sample cut from the flattest part of a windscreen or a specially prepared flat square with material and thickness characteristics identical to those of the actual windscreen, the measurements being taken normal (perpendicular) to the glass pane.

9.1.2.2. The test is carried out in the zone I specified in point 9.2.5.2 of this Annex.

9.1.2.3. In the case of tractors for which it is not possible to determine zone I, the test is carried out in zone I′ as defined in point 9.2.5.3 of this Annex.

The other secondary characteristics are not involved.

9.1.4. Interpretation of results

9.1.4.1. The regular transmittance measured according to section 9.1.2 in the case of windscreens must not be less than 75 %, and in the case of windows other than windscreens not less than 70 %.

9.1.4.2. In the case of windows situated at points which are not essential to the driver's field of vision (glazed roof, for example) the regular transmittance factor of the light from the pane may be less than 70 %. Windows having a regular light transmittance factor of less than 70 % must be marked with an appropriate symbol.

9.2. Optical-distortion test

9.2.1. Scope

The method specified is a projection method which permits evaluation of the optical distortion of a safety-glass pane.

9.2.1.1. Definitions

9.2.1.1.1. Optical deviation: the angle between the true and the apparent direction of a point viewed through the safety-glass pane, the magnitude of the angle being a function of the angle of incidence of the line of sight, the thickness and inclination of the glass pane, and the radius of curvature at the point of incidence.

9.2.1.1.2. Optical distortion in a direction MM′: the algebraic difference in angular deviation Δα measured between two points M and M′ on the surface of the safety-glass pane, the distance between the two points being such that their projections in a plane at right angles to the direction of vision are separated by a given distance Δx (see Figure 6). Anti-clockwise deviation is to be regarded as positive and clockwise deviation as negative.

9.2.1.1.3. Optical distortion at a point M: the optical distortion maximum for all directions MM′ from the point M.

9.2.1.2. Apparatus

This method entails the projection of an appropriate slide (raster) on to the display screen through the safety-glass pane being tested. The change caused in the shape of the projected image by the insertion of the safety-glass pane in the line of light provides a measures of the distortion. The apparatus comprises the following items, arranged as shown in Figure 9.

Figure 6

Diagrammatic representation of optical distortion

Notes:

Δα = α1 - α2, i.e. the optical distortion in the direction MM′.

Δx = MC i.e. the distance between two straight lines parallel to the direction of vision and passing through the points M and M′.

Figure 7

Optical arrangement of the projector

9.2.1.2.1. Projector, of good quality, with a high-intensity point light source, having for example the following characteristics: — focal length at least 90 mm, — aperture approximately 1/2,5, — 150 W quartz halogen lamp (if used without a filter), — 250 W quartz halogen lamp (if a green filter is used). Figure 8 Enlarged section of the slide The projector is shown schematically in Figure 7. A diaphragm of 8 mm diameter is positioned approximately 10 mm from the front lens.

9.2.1.2.2. Slides (rasters) consisting, for example, of an array of bright circular shapes on a dark background (see Figure 8). The slide must be of sufficiently high quality and contrast to enable measurement to be carried out with an error of less than 5 %. In the absence of the safety-glass pane to be examined, the dimensions of the circular shapes must be such that when the circular shapes are projected they form an array of circles of diameter Δx where Δx = 4 mm (see Figures 6 and 9). Figure 9 Arrangement of the apparatus for the optical-distortion test

9.2.1.2.3. Support stand, preferably one permitting vertical and horizontal scanning, as well as rotation of the safety-glass pane.

9.2.1.2.4. Checking template, for measuring changes in dimensions where a rapid assessment is required. A suitable design is shown in Figure 10. Figure 10 Design for a suitable checking template

9.2.1.3. Procedure

9.2.1.3.1. General

Mount the safety-glass pane on the support stand (9.2.1.2.3) at the designated rake angle. Project the test image through the area being examined. Rotate the safety-glass pane or move it either horizontally or vertically in order to examine the whole of the specified area.

9.2.1.3.2. Assessment using a checking template

Where a rapid assessment with a possible margin of error of up to 20 % is sufficient, calculate the value of A (see Figure 10) from the limit value ΔαL for the change in deviation and the value of R 2, the distance from the safety-glass pane to the display screen:

The relationship between the change in diameter of the projected image -d and the change in angular deviation -α is given by:

where:

Δd is expressed in millimetres,

A is expressed in millimetres,

ΔαL is expressed in minutes of arc,

Δα is expressed in minutes of arc, and

R2 is expressed in metres.

9.2.1.3.3. Measurement using a photoelectric device

Where a precise measurement with a possible margin of error of less than 10 % of the limit value is required, measure Δd on the projection axis, the value of the spot width being taken at the point where the luminance is 0,5 times the maximum spot luminance value.

9.2.1.4. Expression of results

Evaluate the optical distortion of the safety-glass panes by measuring -d at any point of the surface and in all directions in order to find Δd max.

9.2.1.5. Alternative method

In addition, a strioscopic technique is permitted as an alternative to the projection techniques, provided that the accuracy of the measurements given in points 9.2.1.3.2 and 9.2.1.3.3 is maintained.

9.2.1.6. The distance Δx must be 4 mm.

9.2.1.7. The windscreen must be mounted at the same rake angle as on the tractor.

9.2.1.8. The projection axis in the horizontal plane must be maintained approximately normal to the trace of the windscreen in that plane.

9.2.2. The measurements are performed in zone I as prescribed in point 9.2.5.2 of this Annex. 9.2.2.1. In the case of tractors for which it is not possible to determine zone I as defined in point 9.2.5.3 of this Annex, the test is carried out in zone I′, as defined in point 9.2.5.3 of this Annex. 9.2.2.2. Tractor type The test must be repeated if the windscreen is to be mounted on a tractor of a type which has a different forward field
