Provides requirements for the design and the construction of compressed natural gas (CNG) fuel systems for motor vehicle engines. It applies to the propulsion engine of a vehicle, or to an auxiliary engine that may be mounted on it. It may be adapted for installations of stationary engines, but is not primarily written for such applications. It does not apply to usage other than to fuel engines, e.g. to supply appliances in caravans.
