耐火试验.房屋建筑构件.镶玻璃构件

[中文适用范围]： 本国际标准提供了一种测试方法，用于确定和评估建筑结构的隔热和非隔热玻璃元件（当这些元件在一个表面上受热时）的耐火性能。 它适用于玻璃分隔元件，如屏幕、玻璃块墙和其他垂直、倾斜或水平方向使用的透光组件，以及所有包含玻璃的分隔元件，打算根据 ISO 834-1 进行评估——除了适用于门和百叶窗组件，旨在根据 ISO 3008 进行测试。 它直接适用于平面元件，但也为金字塔等非平面元件的测试提供指导。 仅当结构符合本国际标准中给出的直接应用领域或根据 ISO/TR 进行扩展应用分析时，测试结果应用于其他未经测试的结构形式才是可接受的12470。 注：由于 ISO/TR 12470 仅给出一般指南，因此特定的扩展应用分析只能由耐火结构方面的专家进行。 [外文原描述]： ISO 3009:2003 provides a test method for determining and assessing the fire resistance performance of both insulated and uninsulated glazed elements of building construction, when those elements are exposed to heating on one face. It is applicable to glazed separating elements such as screens, walls of glass blocks and other light-transmitting assemblies used in vertical, inclined or horizontal orientations, and to all separating elements containing glazing intended to be assessed in accordance with ISO 834-1, except for doors and shutter assemblies, which are intended to be tested in accordance with ISO 3008. It is directly applicable to planar elements, but also gives guidance on the testing of non-planar elements such as pyramids.
