Test of resistance to chemicals
 The purpose of this test is to determine whether the safety glazing material will withstand the effects of exposure to chemicals likely to be normally present or used within the vehicle (e.g. cleaning compounds) without significant deterioration.
8.1.7. Flexibility and fold test
 The purpose of this test is to determine whether a plastic glazing material falls within the rigid or flexible category.
