标准范围

本文件规定了使用散射光、透射光或电离的点型烟雾探测器的要求、试验方法和性能标准，用于建筑物中安装的火灾探测和报警系统（见ISO 7240-1）。本文件还涵盖了点式烟雾探测器，该探测器包含一个以上基于这些原理工作的烟雾传感器。附录N中给出了此类探测器的附加要求和试验方法。对于其他类型的感烟探测器或工作原理不同的感烟探测器的测试，本文件仅用于指导。本文件不适用于针对特定风险开发的具有特殊特性的烟雾探测器。注:某些类型的探测器含有放射性物质。

This document specifies requirements, test methods and performance criteria for point-type smoke detectors that operate using scattered light, transmitted light or ionization, for use in fire detection and alarm systems installed in buildings (see ISO 7240-1). This document also covers point-type smoke detectors that incorporate more than one smoke sensor operating on these principles. Additional requirements and test methods for such detectors are given in Annex N.

For the testing of other types of smoke detectors, or smoke detectors working on different principles, this document is only intended to be used for guidance. This document is not applicable to smoke detectors with special characteristics, developed for specific risks.

NOTE Certain types of detectors contain radioactive materials.
