1.1本国际标准规定了用于安装在船舶上的火灾报警系统的可复位油雾探测器的要求、试验方法和性能标准。油雾探测器可安装在存在易燃液体（如液压、燃料和润滑油系统）点火引起火灾风险的地方。 1.2本国际标准规定了以下探测器的要求: -采用点吸入式取样装置或依靠油雾扩散的点式探测器； -吸气式探测器，采样点与传感单元分离，并使用管道 将采样空气输送至传感单元的网络； -开放路径或光束型探测器，从而将点探测器的概念扩展为采样 路径可以是20米或更多，而不是点式探测器中的几厘米。 1.3对于按照不同原理工作的其他类型探测器的测试，本国际标准仅供参考。针对特定风险以及

1.1 This International Standard specifies requirements, test methods and performance criteria for resettable oil mist detectors for use in fire hazard alarm systems installed on marine vessels. Oil mist detectors may be installed where an identified risk of fire caused by ignition of flammable liquids, such as hydraulic, fuel and lubricating oil systems, exists. 1.2 This International Standard specifies requirements for the following detectors: — point type detectors employing a point aspirating sampling device or relying on dispersion of oil mist; — aspirating detectors, whereby the sampling point is separated from the sensing unit(s) and uses a pipe network for carrying the sampling air to the sensing unit(s); — open path or beam type detectors, whereby the concept of the point detector is expanded to a sampling path which can be 20 m or more, as opposed to a few centimeters in the point type detector. 1.3 For the testing of other types of detector working on different principles, this International Standard is only for guidance. Detectors with special characteristics and developed for specific risks, as well as those
