pane, as defined in paragraph 1.2. of Annexes 5, 7 or 11 to this Regulation.

              2. General

              2.1. Each component glass pane forming the multiple-glazed unit shall either be type-approved or subjected to the requirements set out in the relevant annex to this Regulation (Annexes 5, 7 or 11).

              2.2. Tests carried out on a multiple-glazed unit having one or more gap(s) with the nominal width 'e1' (… 'en') shall be considered to be applicable to all multiple-glazed units having the same characteristics and a nominal width of the gap(s) 'e1± 3 mm' (… 'en ± 3 mm'). However, the applicant for approval may submit for approval tests the sample having the smallest gap(s) and the sample having the largest gap(s).

              2.3. In the case of multiple-glazed units having at least one laminated glass pane or one glass-plastics pane, the test pieces shall be stored for at least four hours prior to the test at a temperature of 23 °C ± 2 °C. The tests shall take place immediately after the test pieces are taken out of the receptacle in which they were stored.

              3. Headform test

              3.1. Index of difficulty of the secondary characteristics

               No secondary characteristic is involved.

              3.2. Number of test pieces

               Six test pieces (1,100 mm x 500 mm)          mm shall be subjected to testing for each category of thickness of the component glass panes and each width of gap as defined in paragraph 1.1.4. above.

              3.3. Test method

              3.3.1. The method used shall be that described in Annex 3, paragraph 3.1.

              3.3.2. The height of drop shall be 1.50 m             mm.

              3.3.3. In the case of an asymmetrical multiple-glazed unit, three tests shall be carried out on one side and three tests on the other side.

              3.4. Interpretation of results

              3.4.1. Multiple glazing consisting of uniformly-toughened glass panes only:

               The test shall be considered to have given a satisfactory result if all components break;

              3.4.2. Multiple glazing …

              3.4.2.1. The components of the test piece yield and break, displaying numerous circular cracks centred approximately on the point of impact;

              3.4.2.2. Tears in the interlayer(s) are allowed provided that the manikin's head does no pass through the test piece.

              3.4.2.3. No large fragment of glass becomes detached from the interlayer.

              3.4.3. Multiple glazing consisting of at least one uniformly-toughened glass pane and of at least one laminated glass pane or glass-plastics pane other than windscreens:

              3.4.3.1. The uniform toughened-glass pane(s) break(s);

              3.4.3.2. The laminated glass pane(s) or glass-plastics pane(s) yield(s) and break(s), displaying numerous circular cracks centred approximately on the point of impact;

              3.4.3.3. Tears in the interlayer(s) are allowed provided that the manikin's head does not pass through the test piece;

              3.4.3.4. No large fragment
