Standards Development
This part of ISO 13785 specifies a screening method for determining the reaction to fire performance of products and constructions of façades claddings when exposed to heat from a simulated external fire with flames impinging directly upon a façade. It is intended for use by producers to reduce the burden of testing in Part 2 of ISO 13785 by eliminating those systems that fail to reach a predefined performance level in the tests described in this part of ISO 13785.
This test method is applicable only to façades claddings that are not free standing and that are used as an addition to an existing free-standing external wall.
This test method provides an intermediate scale test, which should be used for evaluation of sub-components or “families of products” or as a tool for extensions of applications. This test method may also be used as intermediate scale for validation of fire models in façade assessment studies[4] or in fire investigations[5].
This test method also is only applicable to vertical elements and is not applicable to determining the structural strength of the façade cladding.
