This European Standard specifies a method for determining the fire resistance of curtain walling systems – full configuration.This European Standard is used in conjunction with EN 1363-1.NOTE Annex A gives further information on the test method.The test method is applicable to curtain walling systems, supported by the floor slab(s), designed for the purpose of providing fire resistance. The test is not appropriate for testing curtain walling systems which incorporate non-fire resistant glazing.The fire resistance of curtain walling systems can be determined under internal or external exposureconditions. In the latter case the external fire exposure curve gi
