标准摘要
[中文适用范围]： 本文件规定了一种测试方法，用于测定防火阀的耐热性，并评估其防止火灾和烟雾通过空气分配系统从一个防火分区蔓延到另一个防火分区的能力。 适用于机械防火阀。 它不适用于仅用于防烟系统的风门、测试仅处理空气传输应用的消防装置或用于吊顶的风门，因为风门和管道的安装可能会产生不利影响对吊顶的性能，需要采用其他方法进行评价。 注：“空气传输”是通过防火隔离门（或墙壁、地板）的低压应用，无需与空气管道连接。 [外文原描述]： This document specifies a test method for the determination of the resistance of fire dampers to heat, and for the evaluation of their ability to prevent fire and smoke spreading from one fire compartment to another through an air distribution system. It is applicable to mechanical fire dampers. It is not intended to be used for dampers used only in smoke control systems, for testing fire protection devices which only deal with air transfer applications, or for dampers used in suspended ceilings, as the installation of the damper and duct can have an adverse effect on the performance of the suspended ceiling, requiring other methods of evaluation. NOTE "Air transfer" is a low-pressure application through a fire separation door (or wall, floor) without any connection to an air duct.
