Reaction-to-fire tests for façades -- Part 2: Large-scale test
This method is applicable only to façades and claddings that are non-loadbearing. No attempt is made to determine the structural strength of the façade or cladding.
This test is not intended to determine the fire behaviour of a given building façade. 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 façade system as it only is constructed as a façade 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 façade. The most commonly encountered internal re-entrant corner is with an angle of 90°. The test façade 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 façades and claddings of buildings which are otherwise of non-combustible construction.
