标准摘要
[中文适用范围]： ISO 13785 的这一部分规定了一种筛选方法，用于确定产品和外墙或覆层结构在暴露于模拟外部火灾的热量且火焰直接撞击外墙时对防火性能的反应。 它旨在供生产商使用，通过消除那些未通过 ISO 13785 第 2 部分中描述的测试的系统来减轻 ISO 13785 第 2 部分中的测试负担。 此测试方法仅适用于非独立式的外立面和覆层并用作现有外墙的补充。 该测试方法也仅适用于垂直构件，不适用于确定外墙或覆层的结构强度。 [外文原描述]： ISO 13785-1:2002 specifies a screening method for determining the reaction to fire of materials and constructions of façades or 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 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 façade panel construction to fire and the resulting flame spread on or within the façade construction. This test method is applicable only to façades 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 façade or cladding.
