scope:

This International Standard specifies performance and testingrequirements for the gas inflation systems for inflatablelife-saving appliances complying with the requirements of the 1974Safety of Life at Sea Convention (SOLAS 74), as amended, and theIMO International Life-Saving Appliance Code (LSA Code), adopted byIMO Resolution MSC.48(66). For the purposes of this InternationalStandard, the gas inflation system consists of inflation gas,cylinder valve, cylinder operating head, high-pressure hoses, andpressure-relief, inflate/deflate, non-return and transfer valves.This International Standard addresses only systems in whichcompressed inflation gas in cylinders is used as the inflationmedium. Because national requirements for qualification, use, andtesting of gas-cylinders vary widely, requirements for gascylindersare not addressed in this International Standard, but should meetthe requirements of the applicable regulatory bodies. The systemsaddressed in this International Standard are of the type generallyused in primary life-saving appliances such as survival craft,marine evacuation systems, and means of rescue; systems used inpersonal life-saving appliances, such as inflatable lifejackets,are addressed elsewhere.
