标准摘要
[中文适用范围]： ISO 21927的这一部分规定了烟雾屏障的产品性能要求、分类和测试方法，其中包括屏障本身，带或不带相关的激活和驱动装置，设计用于烟雾和热量控制系统。 -它仅涵盖已安装的屏障在建筑物中，即它不覆盖由建筑物结构的一部分制成的屏障。 ISO 21927 的这一部分提供了烟雾屏障系统的测试方法和合格评定。 当存在确定烟雾泄漏率的计算方法时，ISO 21927 本部分仅涵盖防烟屏障。 这要求防烟屏障在两个相邻防烟屏障之间的任何自由接头上被充分固定和引导。 图 E.4 说明了 ISO 21927 本部分不适用的设计。 [外文原描述]： ISO 21927-1:2008 specifies the product performance requirements, classifications and test methods for smoke barriers, which comprise the barrier itself, with or without associated activation and drive devices, designed for use in smoke and heat control systems. ISO 21927-1:2008 provides the test methods for, and conformity assessment of, the smoke barrier systems. It covers only barriers installed in buildings; it does not cover barriers made of part of the building's structure. Smoke barriers are only covered by ISO 21927-1:2008 when calculation methods exist for the determination of the leakage rate of smoke. This requires the smoke barriers to be sufficiently fixed and guided on any free joints between two adjacent smoke barriers. An example is given of a design to which ISO 21927-1:2008 does not apply.
