Number of Windscreens Four windscreens shall be submitted for testing. The term also covers the trade names or marks as specified by the holder of the approval.
The term “indices of difficulty” covers a two-stage grading system applying to the variations observed in practice in each secondary characteristic. The number of component panes.
Abrading instrument shown diagrammatically in Figures 4. Modification or extension of approval of a type of safety glazing material In the case of a sample: The above approval mark affixed to an ordinary laminated-glass windscreen shows that the component concerned has been approved in the Netherlands E4 pursuant to Eve No. Interpretation of Results 6. If not, only the tests prescribed for checking optical qualities as described in Annex 3, Paragraph 9.
Taber Test Apparatus 4. Ec 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. Uniformly-toughened Glass Panes 2. Production Definitely Discontinued Safety glazing shall be subjected to the tests listed in the following table: Benefits at a Glance.
For agricultural and forestry tractors and for construction-site vehicles, the position of the visibility zone shall be indicated in the test report.
Expression of the Results Subtract the average initial haze from the average total light scattered, the difference representing the light scatter resulting from washing the test specimen.
Vehicle submitted for approval on: The temperature of the water in the line where it enters the exposure apparatus shall be r433 ambient water temperature.

Technical service responsible for conducting approval tests: The drop heights measured from the lowest point of the phantom head to the surface of the impact plate are 50,and mm. The wiper blade shall be fixed into the holder as shown below.
Colouring of the plastic product: After r3 test the cuts are examined with a magnifying glass to check that they reach the subsurface. The black panel thermometer shall be mounted in the test specimen rack and readings shall be taken at the point where maximum heat is developed due to light exposure.
Hazemetershown diagrammatically fce Figure 5. The method used shall be that described in Annex 3, Paragraph 1. Colouring colourless or tinted ; 1. The sample shall be placed with the to be tested side facing up representing the outside surface of the plastic glazing part into the sample holder of the sample box onto the right spacer plaque which has a soft masking film on its surface to avoid scratching the test samples backside.
To minimize the temperature change of the test piece the test shall be performed within 30s of the removal of the test piece from the conditioning appliance. Regulations and directives applicable to glass for automotive use are: A test shall rce deemed to have given a satisfactory result if fragmentation satisfies the following conditions: In the event of the windscreen’s shattering, the driver shall still be able to see the road clearly enough to be able to brake and stop his vehicle safely.
A change from Index “1” to Index “2” indicates the need for additional tests. Colouring of plastics coating s: In either case the test pieces shall be in all respects rigorously representative of the serially produced windscreens for which approval is sought. The composition of the multiple-glazed unit symmetrical, asymmetrical1. A set of samples for approval shall be considered satisfactory if all samples meet the requirements. Test exe resistance to chemicals in accordance with the requirements of Annex 18, Paragraph 9.
For windscreens faced with plastics material, the tests prescribed in Paragraph 9.

Impact head form Impact of ecr Optical distortion Light transmittance. The geometric and chemical characteristics and type of the specific device used for the type approval test shall be described in the test report. The apparatus is shown schematically in the following figures and includes at least the following individual components: Resistance-to-humidity Test The requirements of Annex 3, Paragraph 7.
The table below shows the type of samples subject to testing, in accordance with the dimensions of the glazing to be assessed. The above approval mark with plastics material shows that the component concerned has been approved in the Netherlands E4 pursuant to Regulation Ecee.
Number of Test Pieces Six test pieces from the smallest-developed-area series and six samples from the largest-developed-area series, selected as prescribed in Annex 13, shall be tested. A set of test pieces submitted for approval shall be considered satisfactory from the point of view of the g ball test if at least eight of the ten tests carried out at each temperature, have given a satisfactory result.
Any special treatment which one of the layers of plastic may have undergone. The deceleration curve of the drop height of mm shall run at least 1. Resistance-to-radiation Test This test has to be performed at the discretion of the laboratory conducting the tests.
