ISO 7240的本部分规定了使用火焰辐射运行的点式可重置火焰探测器的要求、试验方法和性能标准，用于建筑物中安装的火灾探测系统。 ISO 7240的本部分不适用于针对特定风险开发的具有特殊特性的火焰探测器。它可作为评估ISO 7240本部分未包含的其他类型火焰探测器的指南。 火焰探测器的性能是根据特定试验中获得的结果进行评估的。ISO 7240的本部分无意对此类火焰探测器的设计和构造施加任何其他限制。

This part of ISO 7240 specifies requirements, test methods and performance criteria for point-type, resettable flame detectors that operate using radiation from a flame for use in fire detection systems installed in buildings. This part of ISO 7240 is not applicable to flame detectors with special characteristics, developed for specific risks. It can be used as guidance in assessing other types of flame detectors not included in this part of ISO 7240. The performance of flame detectors is assessed from results obtained in specific tests. This part of ISO 7240 is not intended to place any other restrictions on the design and construction of such flame detectors.
