Number of test pieces. Three flat test pieces 130 mm x 40 mm cut from a flat sheet sample shall be subjected to testing.
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.
Number of test pieces. Six test pieces shall be subjected to testing for each thickness category defined in paragraph 1.1.4. above.
Number of test pieces. 3.2.1. For each group of toughened-glass windscreens, four test pieces having approximately the smallest developed area and four test pieces having approximately the largest developed area, all eight samples being of the same types as those selected for the fragmentation tests (see paragraph 2.2. above), shall be subjected to testing.
3.2.2. Alternatively, at the discretion of the laboratory conducting the tests, for each category of windscreen thickness, six test pieces of the dimension (1,100 mm x 500 mm) + 5 mm shall be subjected to testing.
Number of test pieces. Ten flat test pieces of the outer component sheet or ten finished parts of size 300 x 300 mm +10/-0 mm shall be subjected to testing.
Number of test pieces. Six flat test pieces (1,170 mm x 570 mm +0/-2 mm) or six complete parts shall be subjected to testing. The table below shows the type of samples subject to testing, in accordance with the dimensions of the glazing to be assessed. Small window Diameter D of the circle capable of being scribed: D < 150 mm and area of less than 200 cm2 No test Other than small window Diameter D of the circle capable of being scribed: D < 400 mm and area of at least 200 cm2 1,170 mm x 570 mm (material type testing and standard support frame) Other part of same material, production procedure, thickness, colour with dimensions bigger than those of the original part, into which a 400 mm diameter circle can be scribed, and with a developed surface area of less than 1,170 mm x 570 mm (part type approval for the original part 1) Diameter D of the circle capable of being scribed: 400 mm < D 1,170 mm x 570 mm (material type testing and standard support frame) Real part (submitted for approval) (part type approval and dedicated support frame)
4.3.1. The test method used shall be that described in Annex 3, paragraph 3.2.
4.3.2. For forward facing glazing situated forward of an occupant like partitions and separating windows which have impact probability (classification X/A) the drop height shall be 3 m. The HIC value shall also be measured.
4.3.3. For glazing like side windows, back windows and sunroofs which have reduced impact possibilities (classification X/B) the drop height shall be 1.5 m. The HIC value shall also be measured."
5.1. Indices of difficulty of the secondary characteristics:
(1) Without obscuration(s)
(2) With obscuration(s)
5.2. Number of test pieces Ten flat square pieces of 300 mm +10/-0 mm side of the outer component sheet or ten substantially flat finished parts shall be subjected to testing. In this later case, the contact between the part and the supporting fixture shall be around the whole perimeter and of about 15 mm width. Upper and lower supporting frames shall be clamped together in a way that ensures that the movement of the test piece during the test shall not exceed 2 mm."
Number of test pieces. One test piece for each component sheet of the window measuring 300 mm x 25 mm shall be subjected to testing.
Number of test pieces. Six square test pieces of 300 mm Î ^ side shall be subjected to testing.
Number of test pieces. Three flat test pieces 130 mm x 40 mm cut from the outer skin of the window shall be subjected to testing.
Number of test pieces. Eight flat samples measuring 300 mm x 300 mm, specially made or cut from the flattest part of a pane shall be tested
3.2.1. Test pieces can alternatively be finished products that may be supported over the apparatus described in paragraphs 2.1.1. to 2.1.1.3. of Annex 3.
3.2.2. If the test pieces are curved, care should be taken to ensure adequate contact with the support.
