ISO5925.1 防烟门和卷帘组件漏气试验 – 适用范围

ISO 5925的此部分中描述的测试确定了在指定的测试条件下，环境（冷）和中（温）温烟雾从门和百叶窗组件的一侧泄漏到另一侧的速率。该测试适用于旨在防止火灾时烟雾通过的不同配置的门和百叶窗组件。

The test described in this part of ISO 5925 determines the rate of leakage of ambient (cold) and medium (warm) temperature smoke from one side of door and shutter assemblies to the other under the specified test conditions. The test is applicable to door and shutter assemblies of different configurations intended for purposes of controlling the passage of smoke in case of fire.

The acceptable leakage rates for different situations are not addressed in this part of ISO 5925, but rather are specified by the regulations of the controlling authorities.

The principle of the test is explained briefly in Annex A.
