Official Journal L 129 , 14/05/1992 P. 0011 - 0094 Finnish special edition: Chapter 13 Volume 22 P. 0052  Swedish special edition: Chapter 13 Volume 22 P. 0052  





COUNCIL DIRECTIVE 92/22/EEC of 31 March 1992 on safety glazing and glazing materials on motor vehicles and their trailersTHE COUNCIL OF THE EUROPEAN COMMUNITIES,  Having regard to the Treaty establishing the European Economic Community, and in particular Article 100a thereof,  Having regard to the proposal from the Commission (1),  In cooperation with the European Parliament (2),  Having regard to the opinion of the Economic and Social Committee (3),  Whereas measures should be adopted with the aim of progressively establishing the internal market over a period expiring on 31 December 1992; whereas the internal market comprises an area without internal frontiers in which the free movement of goods,  persons, services and capital is ensured;  Whereas the total-harmonization method will be essential in order fully to achieve the single market;  Whereas this method will have to be used at the time of the revision of the entire EEC type-approval procedure, taking account of the spirit of the Council resolution of 7 May 1985 concerning a new approach to the question of technical harmonization and  standardization;  Whereas the requirements relating to safety glazing differ from one Member State to another; whereas it is consequently necessary for the same requirements to be adopted by all of the Member States, either in addition to or in place of the existing  rules, in order, in particular, to permit implementation, for each type of vehicle, of the EEC type-approval procedure covered by Council Directive 70/156/EEC of 6 February 1970 on the approximation of the laws of the Member States relating to the  type-approval of motor vehicles and their trailers (4), as last amended by Directive 87/403/EEC (5);  Whereas any rules on safety glazing shall contain not only requirements relating to its structure but also to its fitting to vehicles;  Whereas by means of a harmonized procedure for the component type-approval of safety glazing, each Member State shall be able to confirm compliance with common  requirements relating to manufacture and testing and to inform the other Member States of  any such confirmation by forwarding a copy of the component type-approval certificate drawn up for each type of safety glazing; whereas the affixing of an EEC component type-approval mark to any type of safety glazing that conforme to the type that has  been component type-approved means that the official testing of that type of glazing in other Member States is no longer justified;  Whereas the safety aspect of windscreens is especially important since, more than in the case of other types of glazing, they are likely to be subjected to violent impact either as a result of collisions or where there are external shocks and can thus  be the cause of serious bodily injury; whereas, while aiming at the approximation of the laws of the Member States, the differences between which raise barriers to trade, the solution to be adopted must take account of the safety requirements of road  traffic and the need to improve same,  HAS ADOPTED THIS DIRECTIVE:  Article 1  1. Member States shall type-approve any type of safety glazing within the scope defined in Section 1 of Annex I that meets the structural and testing requirements.  2. Member States shall grant whole-vehicle type approval to any vehicle that complies with the fitting requirements laid down in Annex III.  3. The Member State which has granted EEC component type-approval shall take the necessary measures to verify, insofar as is necessary and if need be in cooperation with the competent authorities of the other Member States, that production models  conform to the approved type.  Article 2  All applications for EEC component type-approval shall be made by the manufacturer or his authorized representative in a Member State. That Member State shall issue to the manufacturer or his authorized representative an EEC component type-approval mark  in compliance with items 4.4 to 4.7 of Annex II for each type of safety glazing that it type-approves in pursuance of Article 1.  Member States shall take all necessary measures to prevent the use of any marks liable to create confusion between items of safety glazing that have already been component type-approved pursuant to Article 1.  Article 3  The competent authorities in each Member State shall, within one month, send to the competent authorities of the other Member States a copy of the component type-approval certificate drawn up for each type of safety glazing and with regard to its  fitting, for each type of vehicle to which they grant whole-vehicle type-approval.  Article 4  No Member State may prohibit the marketing or use of safety glazing on grounds relating to its construction where that glazing bears the EEC component type-approval mark.  Article 5  1. If the Member State which has granted EEC component type-approval finds that a number of items of safety glazing bearing the same component type-approval mark do not conform to the approved type, it shall take the necessary measures to ensure that  production models do so conform. The competent authorities of that State shall advise those of the other Member States of the measures taken, which may, where necessary, extend to withdrawal of EEC component type-approval. The said authorities shall  take like measures if they are informed by the competent authorities of another Member State of such failure to conform.  2. The competent authorities of the Member States shall inform each other, within one month, of any withdrawal of EEC component type-approval, and of the reasons for such a measure.  3. If the Member State which has granted EEC component type-approval disputes the failure to conform notified to it, the Member States concerned shall endeavour to settle the dispute. The Community shall be kept informed and shall, where necessary, hold  appropriate consultations for the purpose of reaching a settlement.  Article 6  Any decision taken pursuant to the provisions adopted in implementation of this Directive to refuse or withdraw component type-approval, or prohibit sale and use, shall state in detail the reasons on which it is based. Such decision shall be notified to  the party concerned, who shall at the same time be informed of the remedies available to him under the laws in force in the Member States and of the time-limits allowed for the exercise of such remedies.  Article 7  No Member State may refuse EEC whole-vehicle type-approval or national type-approval of a type of vehicle, or refuse or prohibit the sale, entry into service or use of a vehicle, on grounds relating to its safety glazing if this bears the EEC component  type-approval mark and if it has been fitted in accordance with the requirements set out in Annex III.  Article 8  For the purposes of this Directive, 'vehicle' means any motor vehicle intended for use on the road, having at least four wheels and a maximum design speed exceeding 25 km/h as well as its trailer, with the exception of vehicles which run on rails,  agricultural and forestry tractors or machinery, and construction plant and equipment.  The international classification of these vehicles shall be as set out in Note (b) of Annex I to Directive 70/156/EEC.  Article 9  Any amendments necessary to adapt the requirements of the Annexes to technical progress shall be adopted in accordance with the procedure laid down in Article 13 of Directive 70/156/EEC.  Article 10  1. Member States shall adopt and publish the provisions necessary to comply with this Directive before 1 July 1992 and shall forthwith inform the Commission thereof.  When Member States adopt these measures, they shall contain a reference to this Directive or shall be accompanied by such reference on the occasion of their official publication. The methods of making such a reference shall be laid down by the Member  States.  They shall apply these provisions from 1 October 1992.  2. Member States shall communicate to the Commission the texts of the main provisions of national law which they adopt in the field covered by this Directive.  Article 11  This Directive is addressed to the Member States.  Done at Brussels, 31 March 1992.

SCOPE This Directive applies to safety glazing and materials for glazing intended to be fitted in the form of a windscreen or other glazing or separating panels on motor vehicles and their trailers, and to the fitting thereof, with the exception of glass for  lighting and light-signalling devices and for the dashboard, and special glazing offering protection against attacks, surfaces made entirely of plastic material intended for use in the construction of category 0 vehicles, motor caravans, opening roofs,  the rear windows of convertible vehicles and the sides of off-road vehicles, and windscreens intended for fitting to vehicles used in extreme environments having a maximum speed of 40 km/h.  2. DEFINITIONS For the purposes of this Directive:  2.1. Glazing means a pane of glass consisting of a single sheet of glass having undergone a special treatment intended to increase its mechanical strength and limit its fragmentation when smashed.  2.2. Laminated glazing means: at least two sheets of glass held together by at least one sheet of plastic material that is sandwiched between them; that laminated glass may be:  2.2.1. ordinary if none of the sheets of glass of which it consists has been treated; or 2.2.2. treated if at least one of the sheets of glass of which it consists has undergone a special treatment intended to increase its mechanical strength and to limit its fragmentation when smashed.  2.3. Safety glazing coated with plastic means: glazing as defined in item 2.1 or 2.2 with a coating of plastic material on its inner surface.  2.4. Plastic-glass safety glazing means laminated glazing having a single sheet of glass and one or several sheets of plastic laid one on top of the other, at least one of which serves as a sandwich layer. The sheet(s) of plastic is (are) located on the  inner surface when the glazing is fitted to the vehicle.  2.5. Surface made entirely of plastic material: means a transparent surface manufactured entirely of organic polymeric material.  2.6. Group of windscreens means a group consisting of windscreens having different shapes and dimensions which are subjected to an examination of their mechanical properties, fragmentation characteristics and their behaviour during tests on their  resistance to attack from their environment;  2.6.1. flat windscreen means a windscreen which does not have a nominal curvature represented by a segment height of more than 10 mm per linear metre;  2.6.2. curved windscreen means a windscreen having a nominal curvature represented by a segment height of more than 10 mm per linear metre.  2.7. Double window means a unit consisting of two panes fitted separately into the same aperture on the vehicle.  2.8. Double glazing means a unit consisting of two panes assembled at the factory in a permanent manner and separated by a uniform space;  2.8.1. symmetrical double glazing means double glazing in which the two constituent panes are of the same type (toughened, laminated, etc.) and have the same main and secondary characteristics;  2.8.2. assymetrical double glazing means double glazing in which the two constituent panes are of a different type (toughened, laminated, etc.) or have different main and/or secondary characteristics.  2.9. Main characteristic means a characteristic which significantly alters the optical and/or mechanical properties of a pane of glass with regard to the function that that glass is to perform on the vehicle. This term also includes the trade name or  manufacturer's mark.  2.10. Secondary characteristic means a characteristic which is likely to alter the optical and/or mechanical properties of a unit of glazing in a manner that is significant for the function for which it is intended on the vehicle. Account shall be taken  of the indices of difficulty when the extent of the alteration is estimated.  2.11. Indices of difficulty means a classification into two degrees that are applicable to the variations observed in practice for each secondary characteristic. The transition from index 1 to index 2 is an indication of the need to carry out  traditional tests.  2.12. Developed area of a windscreen means the area of the minimum rectangle of glass from which a windscreen can be made.  2.13. Rake angle of a windscreen means the angle formed by the vertical line and the straight line joining the upper and lower edges of the windscreen, these straight lines being taken in a vertical plane containing the longitudinal access of the  vehicle;  2.13.1. the rake angle is measured on a vehicle on the ground and, where the vehicle is used to carry passengers, that vehicle must be in running order, with a full complement of fuel, liquid coolant and lubricant, with tools and spare wheels in place  (if these are considered to form part of the standard equipment by the vehicle's manufacturer); account shall be taken of the weight of the driver and, where vehicles are intended to carry additional passengers, of the weight of a passenger on the front  seat, the driver and passenger each being taken to a 75 ± 1 kg;  2.13.2. where vehicles are fitted with hydropneumatic, hydraulic or pneumatic suspension or with a device automatically regulating ground clearance as a function of load they shall be tested under the normal operating conditions specified by the  manufacturer.  2.14. Segment height h means the maximum distance separating the internal surface of a unit of glazing from a plane passing through the edges of that unit. This distance shall be measured in a direction which is practically normal to the glazing (see  Annex II M, Figure 1).  2.15. Type of glazing means the glazing defined in items 2.1 to 2.4 which does not display any essential differences, and in particular as regards the main and secondary characters mentioned in Annexes II B, II C, II D, II H, II I, II J, II K and II L;   2.15.1. although a change in the main characteristics means a new type of product, in certain cases it is accepted that a change in shape and dimensions does not necessarily involve an obligation to carry out a full series of tests. For certain of the  tests specified in the separate Annexes glazing units may be grouped together if it is clear that they have similar main characteristics;  2.15.2. glazing units only having different secondary characteristics may be considered to be of the same type; however, certain tests can be carried out on samples of such glazing if those tests are explicitly stipulated in the test conditions.  2.16. Type of vehicle, as regards the fitting of safety glazing, means vehicles which do not show any essential differences, in particular as regards the type of glazing defined in item 2.15 and fitted on the vehicle.  2.17. Curver means the approximate value of the smallest radius of the arc of the windscreen measured at its most inwardly curved part.     ANNEX II  GLAZING - STRUCTURAL AND TESTING REQUIREMENTS, APPLICATION FOR EEC COMPONENT TYPE-APPROVAL, MARKING, EEC COMPONENT TYPE-APPROVAL, AMENDMENT OR EXTENSION OF EEC COMPONENT TYPE-APPROVAL, CONFORMITY OF PRODUCTION MODELS AND PENALTIES FOR NON-CONFORMITY OF  PRODUCTION  1.  STRUCTURAL AND TESTING REQUIREMENTS 1.1.  General specifications 1.1.1.  All types of glass, and in particular glass intended to be used for windscreens must be of a quality enabling the risk of corporal damage in the event of breakage to be reduced as much as possible. The glass must offer adequate resistance to any  stressing which may arise during accidents occurring under normal traffic conditions, and similarly to atmospheric and thermal factors, chemical agents, fire and abrasion.  1.1.2.  In addition safety glass shall be adequately transparent, cause no noticeable deformation of objects seen through the windscreen, nor cause any confusion between the colours used on road signs. In the event of windscreen breakage the driver must  continue to be able to see the road clearly enough in order to be able to brake and bring his vehicle to a halt in complete safety.  1.2.  Individual specifications Depending on the category to which they belong all types of glazing must meet the following individual specifications:  1.2.1.  as regards panes of uniformly toughened glass windscreens, the requirements set out in Annex II H;  1.2.2.  in the case of ordinary laminated glass windscreens, the requirements set out in Annex II B;  1.2.3.  in the case of panes of ordinary laminated glass apart from windscreens, the requirements set out in Annex II I;  1.2.4.  in the case of treated laminated glass windscreens, the requirements set out in Annex II C;  1.2.5.  in the case of plastic-coated safety glass the requirements set out in Annex II K in addition to the appropriate requirements listed above;  1.2.6.  in the case of plastic-glass windscreens, the requirements set out in Annex II D;  1.2.7.  in the case of plastic-glass panes other than windscreens, the requirements set out in Annex II J;  1.2.8.  in the case of double glazing the requirements set out in Annex II L.  1.3.  Tests 1.3.1.  The following tests are prescribed:  1.3.1.1.  Fragmentation The purpose of this test is:  1.3.1.1.1.  to verify that the fragments and splinters produced by smashing of the pane of glass are such as to minimize the risk of injury,  1.3.1.1.2.  in the case of treated laminated glass windscreens to check residual visibility after shattering.  1.3.1.2.  Mechanical strength 1.3.1.2.1.  Ball-impact test There are two tests, one using a 227 g ball and the other a 2 260 g ball.  1.3.1.2.1.1.  Test using the 227 g ball. The aim of this test is to assess the adhesion of the interlayer in laminated glass and the mechanical strength of uniformly toughened glass.  1.3.1.2.1.2.  Test using a 2 260 g ball. The aim of this test is to assess the ability of the laminated glass to resist ball penetration.  1.3.1.2.2.  Headform test The purpose of this test is to verify the glass panes compliance with the requirements relating to the limitation of injury in the event of impact of the head against the windscreen, laminated glass and panes of plastic-glass other than windscreens,  together with the double-glazed units used in the side windows.  1.3.1.3.  Resistance to the environment 1.3.1.3.1.  Abrasion test The purpose of this test is to determine whether the resistance of a safety-glass pane to abrasion exceeds a specified value.  1.3.1.3.2.  High-temperature test The purpose of this test is to verify that no bubbles or other defects occur in the interlayer in a laminated glass or glass-plastics pane when the latter is exposed to high temperatures over an extended period of time.  1.3.1.3.3.  Resistance-to-radiation test The purpose of this test is to determine whether the light transmittance of laminated glass, plastic-glass and plastics-coated glass panes exposed to radiation over an extended period of time is significantly reduced thereby or whether the glazing is  significantly discoloured.  1.3.1.3.4.  Resistance-to-humidity test The purpose of this test is to determine whether a laminated-glass, plastic-glass and plastics-coated glass pane will withstand, without significant deterioriation, the effects of prolonged exposure to atmospheric humidity.  1.3.1.3.5.  Resistance to temperature change The purpose of this test is to determine whether the plastic material(s) used in safety glazing as defined in items 2.3 and 2.4 in Annex I will withstand, without significant deterioration, the effects of prolonged exposure to extreme temperatures.  1.3.1.4.  Optical qualities 1.3.1.4.1.  Light-transmission test The aim of this test is to determine whether the regular transmission of safety-glass panes exceeds a specified value.  1.3.1.4.2.  Optical distortion test The purpose of this test is to verify that the distortion of objects as seen throught the windscreen is not to such an extent as to be likely to confuse the driver.  1.3.1.4.3.  Secondary-image-separation test The purpose of this test is to verify that the angular separation of the secondary image from the primary image does not exceed a specified value.  1.3.1.4.4.  Colour identification test The purpose of this test is to verify that there is no risk of confusion of colours as seen through a windscreen.  1.3.1.4.5.  Fire-resistance test The purpose of this test is to verify that the inner face of a pane of safety glass as defined in items 2.3 and 2.4 in Annex I has a sufficiently low burn rate.  1.3.1.5.  Resistance to chemical agents The purpose of this test is to determine whether the inner surface of a pane of safety glass as defined in items 2.3 and 2.4 of Annex I will withstand, without deterioration, the effects of exposure to the chemical agents likely to be present or used in  a vehicle (for example, cleaning agents).  1.3.2.

Calculate total transmittance Tt = T2/T1.  Calculate the diffuse transmittance Td as follows:   Td = T4-T3 (T2/T1) T1  Calculate the percentage haze, or light, or both, scattered, as follows:   Td Tt  × 100 %.   Measure the initial haze of the test piece at a minimum of four equally-spaced points in the unabraided 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 three rev/sec or more.  For each pane of safety glass carry out three tests under the same loading. Use the hazing as a measure of the subsurface abrasion after the test piece has been subjected to the abrasion test.  Measure the light scattered by the abraided track at a minimum of four equally-spaced points along the track in accordance with the formula above. Average results for each test piece. In lieu of the four measurements an average value may be obtained by  rotating the piece uniformly at three rev/sec or more.  4.5.  The abrasion test will be carried out only at the discretion of the laboratory conducting the test with due regard to the information already at its disposal.  Except where plastic-glass is used, there are changes in the interlayer or material thickness, further testing will as a general rule not be required.  4.6.

Anti-clockwise deviation should 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& prime; from the point M.  9.2.1.2.  Apparatus This method entails the projection of an appropriate slide (raster) onto 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 sight  provides a measure of the distortion. The apparatus shall comprise the following items, arranged as shown in Figure 9.  Notes: AEa = á1-á2, i.e. the optical distortion in the direction MM& prime;.  AEx = MC i.e. the distance between two straight lines parallel to the direction of vision and passing through the points M and M& prime;.  9.2.1.2.1.  Projector, of good quality, with a high-intensity point light source, having for example the following characteristics:  - focal length of at least 90 mm,  - aperture approximately 1/2,5,  - 150 W quartz halogen lamp (used without a filter),  - 250 W quartz halogen lamp (if used with a green filter).  The projector is shown schematically in Figure 7. A diaphragm of 8 mm diameter is positioned approximately 100 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 slides shall be of sufficiently high quality and contrast to enable measurements 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 shape shall be such that when they are projected they form an array of circles of diameter  R1 + R2 R1  AEx on the screen, where AEx = 4 mm (see Figures 6 and 9).  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 desired. A suitable design is shown in Figure 10.  9.2.1.3.  Procedure 9.2.1.3.1.  General Mount the safety-glass pane on the support stand (item 9.2.1.3.2) at the specified 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 AEáL for the change in deviation and the value of R2, for the distance from the safety-glass  pane to the display screen:  A = 0,145 AEáL · R2 The relationship between the change in diameter of the projected image AEd and the change in angular deviation AEá is given by:  AEd = 0,29 AEá · R2 where:  AEd is in millimeters,  A is in millimeters,  AEáL is in minutes of an arc,  AEá is in minuts of an arc,  R2 is in metres.  9.2.1.3.3.  Measurements 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 AEd 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 AEd at any point on the surface and in all directions in order to find AEd 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 items 9.2.1.3.2 and 9.2.1.3.3 is maintained.  9.2.1.6.  The distance AEx shall be 4 mm.  9.2.1.7.  The windscreen shall be mounted at the same rake angle as on the vehicle.  9.2.1.8.

Type of vehicle The tests shall be repeated if the windscreen is to be mounted on a vehicle of a type which has a different forward field of vision from that of the vehicle type for which the windscreen has already been component type approved.  9.2.3.  Indices of difficulty of the secondary characteristics 9.2.3.1.  Nature of the material  Polished plate glass Float glass Sheet glass 1 1 2  9.2.3.2.  Other secondary characteristics No other secondary characteristics are involved.  9.2.4.  Number of samples Four samples shall be submitted for testing.  9.2.5.  Definitions of zones 9.2.5.1.  In the case of windscreens fitted to category M1 vehicles, zones A and B are those defined in Annex II F.  9.2.5.2.  In the case of category M and N vehicles other than those in category M1, the zones are defined starting from:  9.2.5.2.1.  an ocular point normal to the R point for the driver's seat and 625 mm above that point in the vertical plane parallel to the median longitudinal plane of the vehicle for which the windscreen is intended, and passing through the axis of the steering  wheel. This point is designated by O below;  9.2.5.2.2.  a line OQ, this being the horizontal straight line passing through ocular point O and running normal to the median longitudinal plane of the vehicle.  9.2.5.2.3.  Zone I - the zone of the windscreen bounded by the intersection of the windscreen with the four following planes:  P1 - a vertical plane passing through the O point and forming an angle of 15o to the left of the median longitudinal plane of the vehicle;  P2 - a vertical plane symmetrical to P1 in relation to the median longitudinal plane of the vehicle.  If such an arrangement is impossible (absence of median longitudinal plane of symmetry, for example), the plane symmetrical to P1 in relation to the longitudinal plane of the vehicle passing through the A point is taken to be P2;  P3 - a plane containing right angle OQ and forming an angle of 10o above the horizontal plane;  P4 - a plane containing straight line OQ and forming an angle of 8o below the horizontal plane.  9.2.6.  Interpretation of results The type of windscreen shall be considered satisfactory as regards optical distortion if, in the four samples submitted for testing, optical distortion does not, in each zone, exceed the following maximum values:   Vehicle category Zone Maximum optical distortion values M1 A - Extent in accordance with item 9.2.2.1 2& prime; of an arc B 6& prime; of an arc M categories other than M1,  and N  I  2& prime; of an arc  9.2.6.1.  No measurement shall be carried out in a 25 mm-wide peripheral zone on category M and N vehicles.  9.2.6.2.  In the case of divided windscreens no check is performed within a band of 35 mm in width starting from the edge of the pane, which may be adjacent to the screen divider.  9.2.6.3.  A tolerance of up to 6& prime; of an arc is permitted for all parts of zone I or of zone A at least 100 mm from the edges of the windscreen.  9.2.6.4.  Slight departures from the requirements are tolerated in zone B, provided that these are localized and mentioned in the test report.  9.3.  Secondary-image-separation test 9.3.1.  Scope Two test methods are recognidzed:  - target test, and - collimator-telescope test.  These tests may be used for component type-approval, quality control or product evaluation purposes, as appropriate.  9.3.1.1.  Target test 9.3.1.1.1.  Apparatus This method involves viewing an illuminated target through the safety-glass pane. The target may be designed in such a way that the test can be carried out on a simple 'go-no go' basis. The target shall preferably be one of the following types:  (a) an illuminated 'ring' target whose outer diameter, D, subtends an angle of N minutes of an arc at a point situated at x metres (Figure 11a); or (b) an illuminated 'ring and spot' target whose dimensions are such that the distance, D from a point on the edge of the spot to the nearest point on the inside of the ring subtends and angle of n minutes of an arc at a point situated at x metres  (Figure 11b);  where:  n is the limit value of secondary-image separation,  x is the distance from the safety-glass pane to the target (not less than 7 m),  D is given by the formula D = x. tan n.  The illuminated target consists of a light box, approximately 300 × 300 × 150 mm, whose front is most inconveniently constructed of glass masked with opaque black paper or coated with matt black paint. The box shall be illuminated by a suitable light  source. The inside of the box shall be coated with matt white paint.  It may be convenient to use other forms of target such as that shown in Figure 14. It is also acceptable to replace the target system by a projection system and to examine the resulting images on a screen.  9.3.1.1.2.  Procedure Mount the safety glass pane at the specified rake angle on a suitable stand in such a way that the observation is carried out in the horizontal plane passing through the centre of the target.  The light box shall be viewed, in a dark or semi-dark room, through each part of the area being examined, in order to detect the presence of any secondary image associated with the illuminated target. Rotate the safety-glass pane as necessary to ensure  that the correct direction of view is maintained. A monocular may be used for viewing.  9.3.1.1.3.  Expression of results Determine whether,  - when the target is used (see Figure 11a), the primary and secondary images of the circle separate i.e. whether the limit value of n is exceeded, or,  - when target (b) is used (see Figure 11b), the secondary image of the spot shifts beyond the point of tangency with the inside edge of the circle, i.e. whether the limit value of n is exceeded.  1. Lamp bulb.  2. Condenser aperture > 8,6 mm.  3. Ground-class screen aperture > condenser aperture.  4. Colour filter with central hole approximately 0,3 mm in diameter; diameter > 8,6 mm.  5. Polar-coordinate plate, diameter > 8,6 mm.  6. Achromatic lens, f & {Ì8}; 86 mm, aperture 10 mm.  7. Achromatic lens, f & {Ì8}; 86 mm, aperture 10 mm.  8. Black spot, diameter approximatelx 0,3 mm.  9. Achromatic lens, f = 20 mm, aperture & {Ì9}; 10 mm.  9.3.1.2.  Collimation-telescope test If necessary, the procedure described in this paragraph shall be applied.  9.3.1.2.1.  Apparatus The apparatus comprises a collimator and a telescope and may be set up in accordance with Figure 19. However, any equivalent optical system may be used.  9.3.1.2.2.  Procedure The collimation telescope forms, at infinity, the image of a polar coordinate system with a bright point at its centre (see Figure 14).  In the focal plane of the observation telescope a small opaque spot with a diameter slightly larger than that of the projected bright point is placed on the optical axis, thus obscuring the bright point.  When a test piece which exhibits a secondary image is placed between the telescope and the collimator a second, less bright, point appears at a certain distance from the centre of the polar coordinate system. The secondary image separation can be read  out as the distance between the points seen through the observation telescope (see Figure 14).  (The distance between the dark spot and the bright spot at the centre of the polar coordinate system represents the optical deviation).  9.3.1.2.3.  Expression of results The safety glass pane shall first be examined by a simple scanning technique to establish the area giving the strongest secondary image.  That area shall then be examined by the collimator-telescope system at the appropriate angle of incidence. The maximum secondary-image separation shall then be measured.  9.3.1.3.  The direction of observation in the horizontal plane shall be maintained approximately normal to the trace of the windscreen in that plane.  9.3.2.  The measurements shall be carried out in accordance with the vehicle categories in the zones as defined in item 9.2.2 above.  9.3.2.1.  Vehicle type The test shall be repeated if the windscreen is to be mounted on a vehicle of a type which has a forward field of vision different from that of the type of vehicle for which the windscreen has already been component type approved.  9.3.3.  Indices of difficulty of the secondary characteristics 9.3.3.1.  Nature of the material  Polished plate glass Float glass Sheet glass 1 1 2  9.3.3.2.  Other secondary characteristics No other secondary characteristics are involved.  9.3.4.  Number of samples Four samples shall be submitted for testing.  9.3.5.  Interpretation of results A type of windscreen shall be considered satisfactory as regards secondary-image separation if, in the four samples submitted for testing, separation of the primary and secondary image does not exceed the following maximum values for each zone:   Vehicle category Zone Maximum values for separation of primary and secondary images M1 A - Extent in accordance with item 9.2.2.1 15& prime; of an arc B 25& prime; of an arc Category M other than M1 and N I 15& prime; of an arc  9.3.5.1.  No measurement shall be carried out in a 25 mm-wide peripheral zone in the case of category M and N vehicles.  9.3.5.2.  In the case of divided windscreens no check is performed within a band 35 mm in width, starting from the edge of the pane, which may be adjacent to the screen divider.  9.3.5.3.  A tolerance of up to 25& prime; of an arc is permitted for all of the parts of zone I or of zone A situated less than 100 mm from the edges of the windscreen.  9.3.5.4.  Slight departures from the requirements are tolerated in zone B provided that these are localized and mentioned in the test report.  9.4.  Identification-of-colours test When a windscreen is tinted in the zones defined in item 9.2.5.1 or 9.2.5.2 four windscreens shall be tested for identifiability of the following colours:  - white,  - selective yellow,  - red,  - green,  - blue,  - amber.  10.  FIRE-RESISTANCE TEST 10.1.  Purpose and scope This method enables the horizontal burning rate of the materials used in the passenger compartment of motor vehicles (passenger cars, lorries, station wagons, motor buses) to be determined after exposure to a small flame.  This method permits testing of the materials and coverings used inside vehicles to be tested either individually or in combination up to a thickness of 13 mm. It is used to judge the uniformity of production batches of such materials in respect of their  burning behaviour.  Because of the many differences between the real-world situation and the precise test conditions prescribed herein (application and orientation within a vehicle, conditions of use, ignition sources, etc.) this method cannot be considered to be suitable  for evaluation of all true in-vehicle burning characteristics.  10.2.  Definitions 10.2.1.  Burning rate: the quotient of the burnt distance, measured in accordance with this method, and the time taken to burn at that distance.  It is expressed in millimetres per minute.  10.2.2.  Composite material: a material consisting of several layers of similar or different materials closely held together at their surface by cementing, bonding, cladding, welding, etc.  When different materials are connected together intermittently (for example by sewing, high frequency welding, riveting, etc.), thus permitting the taking of individual samples in accordance with item 10.5, such materials shall not be considered to be  composite materials.  10.2.3.  Exposed side: the side which is facing towards the passenger compartment when the material is fitted to the vehicle.  10.3.  Principle A sample is held horizontally in a U-shaped holder and is exposed to the action of a defined low-energy flame for 15 seconds in a combustion chamer, the flame acting on the free edge of the sample. The test determines whether and when the flame is  extinguished, or the time the flame requires to travel over a measured distance.  10.4.  Apparatus 10.4.1.  Combustion chamber (Figure 15), preferably made of stainless steel, having the dimensions given in Figure 16.  The front of the chamber contains a flame-proof observation window, which may cover the entire front and which can act as an access panel.  The bottom of the chamber has vent holes and the top has a vent slot all around.  The combustion chamber is placed on four feet, 10 mm high. The chamber may have a hole at one end for the introduction of the sample holder containing the sample; in the opposite end a hole is provided for the gas-supply line. Melted material is caught  in a pan (see Figure 17) which is placed on the bottom of the chamber between the vent holes without covering any of them.  10.4.2.  Sample holder consisting of two U-shaped metal plates or frames of corrosion-proof material. The dimensions are given in Figure 18.  The lower plate is equipped with pins and the upper one with corresponding holes in order to ensure a consistent holding of the sample. The pins also serve as measuring points at the beginning and end of the burning distance.  Intervals over the bottom U-shaped frame (see Figure 19).  The lower side of the sample shall be 178 mm above the floor plate; the distance of the front edge of the sample holder from end of the chamber shall be 22 mm; the distances of the longitudinal sides of the sample holder from the sides of the chamber  shall be 50 mm (all inside dimensions) (see Figures 15 and 16).  10.4.3.  Gas burner The small ignition source is provided by a Bunsen burner having an inside diameter of 9,5 mm. It is so located in the test cabinet that the centre of its nozzle is 19 mm below the centre of the bottom edge of the open end of the sample (see Figure 16).   10.4.4.  Test gas The gas supplied to the burner shall have calorific value of about 38 MJ/m³ (for example natural gas).  10.4.5.  Metal comb, at least 110 mm in length, with seven or eight smooth rounded teeth per 25 mm.  10.4.6.  Stop-watch, accurate to 0,5 sec.  10.4.7.  Fume cupboard The cumbustion chamber may be placed in a fume-cupboard assembly provided that the latter's internal volume is at least 20 times, but not more than 110 times, greater than the volume of the combustion chamber and provided that no single height, width,  or length dimension of the fume cupboard is greater than 2¹/2 times either of the other two dimensions.  Before the test the vertical velocity of the air through the fume cupboard shall be measured 100 mm forward of and to the rear of the ultimate site of the combustion chamber. It shall be between 0,10 and 0,30 m/s in order to avoid possible discomfort to  the operator from combustion products. It shall be possible to use a fume cupboard with natural ventilation and an appropriate air velocity.  10.5.  Samples 10.5.1.  Shape and dimension The shape and dimensions of samples are given in Figure 20. The thickness of the sample corresponds to the thickness of the product to be tested. It shall not be more than 13 mm. When sample-taking so permits, the sample shall have a constant section  over its entire length. When the shape and dimensions of a product do not permit a sample of a given size to be taken, the following minimum dimensions shall be maintained:  (a) for samples having a width of 3 to 60 mm, the length shall be 356 mm. In this case the material is tested over the product width;  (b) for a sample having a width of 60 to 100 mm the length shall be at least 138 mm. In this case the potential burning distance corresponds to the length of the sample, the measurement starting at the first measuring point;  (c) samples less than 60 mm wide and less than 356 mm long, and samples 60 to 100 mm wide and less than 138 mm long cannot be tested in accordance with the present method, nor can samples less than 3 mm wide.  10.5.2.  Sampling At least five samples shall be taken from the material under test. In materials having burning rates differing according to the direction of the material (this being established by preliminary tests) the five (or more) samples shall be taken and placed  in the test apparatus in such a way that the highest burning rate will be measured. When the material is supplied in set widths a length of at least 500 mm covering the entire width shall be cut. From the piece so cut the samples shall be taken at a  point not less than 100 mm from the edge of the material and at points equidistant from each other.  Samples shall be taken in the same way from finished products when the shape of the product so permits. If the thickness of the product is over 13 mm it shall be reduced to 13 mm by a mechanical process applied to the side which does not face a  passenger compartment.  Composite materials (see item 10.2.2) shall be tested as if they were homogeneous.  In the case of materials comprising superimposed layers of different composition which are not considered to be composite materials, all the layers of material included within a depth of 13 mm from the surface facing towards the passenger compartment  shall be tested individually.  10.5.3.  Conditioning The samples shall be coditioned for at least 24 hours, but not more than seven days, at a temperature of 23 ± 2 oC and a relative humidity of 50 ± 5 % and be maintained under these conditions until immediately prior to testing.  10.6.  Procedures 10.6.1.  Place samples with napped or tufted surfaces on a flat surface, and comb twice against the nap using the comb (item 10.4.5).  10.6.2.  Place the sample in the sample holder (item 10.4.2) so that the exposed side faces downwards towards the flame.  10.6.3.  Adjust the gas flame to a height of 38 mm using the mark on the chamber, the air intake of the burner being closed. The flame shall burn for at least one minute, for stabilization, before the first test is started. 10.6.4.  Push the sample-holder into the combustion chamber so that the end of the sample is exposed to the flame, and after 15 seconds cut off the gas flow.  10.6.5.  Measurement of the burning time starts at the moment when the foot of the flame passes the first measuring point. Observe the flame propagation on the side (upper or lower) which burns faster.  10.6.6.  Measurement of the burning time is completed when the flame has come to the last measuring point or when the flame is extinguished before reaching that point. If the flame does not reach the last measuring point, measure the burnt distance up to the  point where the flame is extinguished. The burnt distance is that part of the sample destroyed, on the surface or inside, by burning.  10.6.7.  If the sample does not ignite or does not continue burning after the burner has been extinguished, or the flame goes out before reaching the first measuring point, so that no burning time can be measured, note in the test report that the burning speed  is 0 mm/min.  10.6.8.  When running a series of tests or performing repeat tests make sure before starting a test that the temperature of the combustion chamber and sample holder does not exceed 30 oC.  10.7.  Calculation The burning rate B, in mm per minute, is given by the formula:   B = s t  × 60  where:  s is the burnt distance, in millimetres,  t is the time, in seconds, taken to burn the distance s.  10.8.  Indices of difficulty of the secondary characteristics No secondary characteristics are involved.  10.9.  Interpretation of results  Plastic coated (item 2.3 in Annex I) and plastic safety glazing (item 2.4 in Annex I) should be considered satisfactory from the point of view of burning behaviour (fire resistance) if the burn rate does not exceed 250 mm minute.  11.

Interpretation of the results 11.4.1.  The test for resistance to chemical agents shall be considered to be positive if the test piece displays no softening, stickiness, surface cracking or apparent loss of transparence.  11.4.2.  A series of test pieces submitted for component type-approval shall be considered satisfactory as regards resistance to chemical agents if one of the following conditions has been met:  11.4.2.1.  all the tests give positive results;  11.4.2.2.  a test having given an unsatisfactory result, a further series of tests carried out on a new set of test pieces gives satisfactory results.
