After testing the test pieces shall be stored for at least 48 hours at a temperature of 23 °C ± 2 °C and a relative humidity of 50 ± 5 per cent, and then subjected to the 227 g ball drop test described under item 5 of this annex.

              7. Optical qualities

               The requirements of Annex 3, paragraph 9.1. shall apply for products which are requisite for driver visibility.

              7.1. Interpretation of results

               A set of test pieces shall be considered as satisfactory if one of the following conditions is met:

              7.1.1. All test pieces give satisfactory results.

              7.1.2. One test piece having given an unsatisfactory result, a further set of test pieces gives satisfactory results.

              8. Fire resistance test

              8.1. Indices of difficulty and test method

               The requirements of Annex 3, paragraph 10., shall apply.

              8.2. Interpretation of results

               The fire-resistance test shall be considered to have given a satisfactory result if the burning rate is less than 110 mm/min.

              8.2.1. For the purpose of approval a set of samples will be considered satisfactory if one of the following conditions is met:

              8.2.1.1. All samples give a satisfactory result.

              8.2.1.2. One sample having given an unsatisfactory result a second set of samples gives satisfactory results.

              9. Resistance to chemicals

              9.1. Indices of difficulty and test method

               The requirements of Annex 3, paragraph 11., shall apply.

  Flexible plastic panes
              1. Definition of type

               Flexible plastic panes shall be considered to belong to different types if they differ in at least one of the following principal or secondary characteristics.

              1.1. The principal characteristics are as follows:

              1.1.1. Trade names or marks,

              1.1.2. The chemical designation of the material.

              1.1.3. The classification of the material by the manufacturer.

              1.1.4. The process of manufacture.

              1.1.5. The nominal thickness (e), a manufacturing tolerance being allowed:
              ± (0.1 mm + 0.1 . e); d > 0.1 mm.

              1.1.6. The colouring of the plastic product.

              1.1.7. The nature of the surface coating(s).

              1.2. The secondary characteristics are as follows:

              2. General

              2.1. In the case of flexible plastic glazings the tests shall be conducted on flat test pieces which either are cut from finished products or are specially produced for that purpose. In both cases the test piece shall in every respect be rigorously representative for the glazing which are produced in the run and for which approval is being sought.

              2.2. The test pieces shall
