标准范围

ISO 13785-1:2002规定了一种筛选方法，用于确定当暴露在模拟外部火灾的热量中时，正面或覆层材料和结构的火灾反应，火焰直接撞击正面。它旨在通过消除那些未通过ISO 13785-1:2002中所述测试的系统，供生产商使用，以减轻ISO 13785-2:2002中的测试负担。测试方法包括观察立面面板结构在火灾中的行为，以及由此产生的火焰在立面结构上或内部蔓延。本试验方法仅适用于非独立式立面和覆层，以及通过添加到现有外墙中使用的立面和覆层。本试验方法也仅适用于垂直构件，不适用于确定立面或覆层的结构强度。

ISO 13785-1:2002 specifies a screening method for determining the reaction to fire of materials and constructions of fa？ades or claddings when exposed to heat from a simulated external fire with flames impinging directly upon a fa？ade. It is intended for use by producers to reduce the burden of testing in ISO 13785-2:2002 by eliminating those systems that fail the tests described in ISO 13785-1:2002.The test method consists of observing the behaviour of the fa？ade panel construction to fire and the resulting flame spread on or within the fa？ade construction.This test method is applicable only to fa？ades and claddings that are not free standing and that are used by adding to an existing external wall.This test method also is applicable only to vertical elements and is not applicable to determining the structural strength of the fa？ade or cladding.
