1.1 This 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 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). 1.3 For the testing of other types of detectors working on different principles, this standard should only be used for guidance. Detectors with special characteristics and developed for specific risks as well as those designed for use in explosive atmospheres are not covered by this standard.
