标准范围

ISO 7240-7:2011规定了在建筑物内安装的火灾探测和报警系统中使用散射光、透射光或电离的点式烟雾探测器的要求、试验方法和性能标准（见ISO 7240-1）。ISO 7240-7:2011还包括点式烟雾探测器，该探测器包含一个以上基于这些原理工作的烟雾传感器。给出了此类探测器的附加要求和试验方法。对于其他类型的烟雾探测器或工作原理不同的烟雾探测器的测试，ISO 7240-7:2011仅可用于指导。不包括针对特定风险开发的具有特殊特性的烟雾探测器。各国对含有放射性物质的探测器辐射防护的国家要求各不相同，ISO 7240中没有规定-7:2011.

ISO 7240-7:2011 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). ISO 7240-7:2011 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.For the testing of other types of smoke detectors, or smoke detectors working on different principles, ISO 7240-7:2011 can be used only for guidance.Smoke detectors with special characteristics, developed for specific risks, are not covered.The national requirements for protection from radiation from detectors that contain radioactive materials differ from country to country and are not specified in ISO 7240-7:2011.
