1 Scope

This standard specifies the performance requirements, test methods and indicators required for oil mist detectors for marine fire alarm systems. This standard Fixed oil mist detectors are mainly installed in hydraulic oil, fuel and lubricating oil systems and other premises may cause flammable liquid leaks.

This standard applies to the ship point, inhalation, open or beam oil mist detector design, manufacture and testing, based on other working principles the oil mist detector can be used for reference. This standard does not apply to specific hazards and explosive environment special detectors.
