ISO 13785-2:2002: Reaction-to-fire tests for fa?ades -- Part 2: Large-scale test

ISO 13785-2摘要
ISO 13785-2:2002 specifies a method of test for determining the reaction to fire of materials and construction of fa?ade claddings when exposed to heat and flames from a simulated interior compartment fire with flames emerging through a window opening and impinging directly on the fa?ade. The information generated from this test may also be applicable to the scenario of an external fire impinging on a fa?ade; however, the results may not be applicable for all fire exposure conditions.

This method is applicable only to fa?ades and claddings that are non-loadbearing. No attempt is made to determine the structural strength of the fa?ade or cladding.

This test is not intended to determine the fire behaviour of a given building fa?ade. Details such as balconies, windows, window shutters, curtains, etc., are not considered in this test. This test does not include the risk of fire spread e.g. through the window details of the fa?ade system as it only is constructed as a fa?ade wall. There is clear evidence that an internal corner (also called a re-entrant corner) configuration produces a more intense fire exposure than a flat fa?ade. The most commonly encountered internal re-entrant corner is with an angle of 90°. The test fa?ade specimen therefore contains an internal corner with a re-entrant angle of 90°.

The test method described is intended to evaluate the inclusion of combustible components within fa?ades and claddings of buildings which are otherwise of non-combustible construction.
