标准范围

ISO 7240-12规定了建筑物火灾探测系统中使用的线型烟雾探测器的要求、试验方法和性能标准。探测器至少包括发射器和接收器，并可包括反射器，用于通过光束衰减和/或衰减变化来检测烟雾。ISO 7240的本部分不包括设计用于在间距小于1m的相对部件之间运行的线型烟雾探测器；通过整体机械连接定义或调整光程长度的线型烟雾探测器；线-具有特殊特性的烟雾探测器，不能通过ISO 7240本部分中的试验方法进行评估。

ISO 7240-12 specifies requirements, test methods and performance criteria for line type smoke detectors for use in fire detection systems installed in buildings. The detectors consist of at least a transmitter and a receiver and can include reflector(s), for the detection of smoke by the attenuation and/or changes in attenuation of an optical beam.This part of ISO 7240 does not cover line-type smoke detectors designed to operate with separations between opposed components of less than 1 m; line-type smoke detectors whose optical path length is defined or adjusted by an integral mechanical connection; line-type smoke detectors with special characteristics, which cannot be assessed by the test methods in this part of ISO 7240.
