Nominal thickness of the layer s of plastics acting as interlayer: Test of resistance to abrasion in accordance with the requirements of Annex 18, Paragraph 6.

The points of impact shall be selected as follows: The test for resistance to high temperature shall be considered r34 give a positive result if bubbles or other defects are not formed more than 15mm from an uncut edge or 25mm from a cut edge of the test piece or sample or more than 10mm r4 of any cracks which may occur during the test.

If a Party to the Agreement which applies this Regulation withdraws an approval it had previously granted, it shall forthwith so notify the other Contracting Parties applying this Regulation thereof by means of a copy of a communication form conforming to the model in Annex 1 to this Regulation.

A spacer plaque adjusted to the thickness of the test sample so that the test sample surface and the bottom surface of the sample box are on the same height no visible gap in ecf between sample and bottom surface of the sample box shall be placed into the hole in the bottom of the sample box. Test Method Cut through the coating on to the subsurface a pattern with 6 cuts and perpendicular to this another one so that a grid with 25 squares arises grid-cut.

Purpose and Scope of Application This method enables the horizontal burning rate of materials used in the passenger compartment of motor vehicles for example, private passenger cars, lorries trucksestate cars, motor coaches after exposure to a small flame to be determined.

This beam shall not be vignette at either port of the sphere. Headform test, without HIC measurement, in accordance with the requirements of Annex 19, Paragraph 4. Visibility zone of varying fragmentation, always including a rectangular part at least 20cm high and ecr long; 2. The samples exe be completely immersed in the test fluid and held for one minute, then removed and immediately wiped dry with a clean absorbent cotton cloth. The choice of test pieces shall be representative of the production of the various types of windscreen.

When the test piece is placed against the entrance port of the integrating sphere, the angle rr43 the perpendicular to the test piece and a line connecting the centres of entrance and exit ports shall not exceed 0. Any additional markings, as described in Paragraph 5. In the geometric centre of the glass.

The safety glazing through which the driver’s forwards field of vision as defined in Paragraph 2. Classification of the material: Furthermore control visually that the wiper blade rest on the base plate uniformly without losing contact to the base plate at any point of the wiper blade. Using a soft bristle, anti-static brush, lightly brush off any debris adhered to the surface of the test pieces or alternatively rinse the test pieces with distilled, deionized or demineralised water.

R34 shall not be checked in a strip 2cm wide round the edge of the samples, this strip representing the frame of the glass; nor within a radius of 7. The maximum height of segment of the windscreen, 3. A maximum value of 25′ of arc is permitted for all portions of Zone I or Zone A in a peripheral area mm inboard of the design glass outline.

Interpretation of Results A windscreen type shall be considered satisfactory with respect to optical distortion if, in the four windscreens submitted for testing, optical distortion does not exceed the values given below for each zone or test area. If the abrasion track is not homogeneous, up to ecr equally spaced points along the track may be measured.

Headform Test without Deceleration Measurement 3. Determine the initial haze of the sample as in Annex 3, Paragraph 4.

Description of the commercially available specific device mentioned in Annex 3, Paragraph 4. The colouring of the glass colourless or tinted. Vehicle type The test shall be repeated if the windscreen is to be fitted to a vehicle of a type in which the forward field of vision differs from that of the vehicle type for which the windscreen has already been approved.

The extent of such modification is assessed in relation to the indices of difficulty. The abrasion test in accordance with the requirements of Annex 14, Paragraph 6.

A test shall be deemed to have given a satisfactory result if fragmentation satisfies the following conditions: General Requirement This test shall be performed only if the laboratory deems it useful in the light of the information in its possession concerning the interlayer. The colouring total or partial of the interlayer or interlayers colourless or tinted1. Fragmentation test in accordance with the requirements of Annex 5, Paragraph 2. The entrance and exit ports shall be centred on the same great circle of the sphere, and there shall be at least 2.

Taber Test Apparatus 4. Test Pieces Natural quartz sand of grain size of 0. In the case of a sample: The inclination angle of the windscreen, 3.

The position and size of the zones in which the optical ec are eve and, where appropriate, the area subjected to differential toughening, 3. Alternatively a curved pane may be tested. Interpretation of Results 7.

It is essential that the position of the box leads to a wiping area in exactly the middle of the sample see 2 in Figure Indices of Difficulty of the Secondary Characteristics Colourless Tinted Colouring of the interlayer or of the 2 2 plastic coating The other secondary characteristics are not concerned.

For flat glass panes and curved glass panes the points of impact represented rr43 in Annex 20, Figures 3 a and 3 b on the one hand, and in Annex 20, Figure 3 c on the other hand, shall be as follows: D at least cm Diameter D of the circle capable of being scribed:
