Road vehicles - the use of compressed natural
gas fuel for vehicle engines - code of practice
(Second revision)
This Malaysian Standard specifies requirements for compressed natural gas (CNG) fuel
systems for engines mounted on motor vehicles, either for the propulsion of the vehicles or for
driving some auxiliary function, e.g. a mixer or a pump. It provides requirements for the
design and construction of component parts, and for their installation in vehicles, and for
tests, commissioning, and periodic inspection. It applies to all vehicle types, e.g. rigid chassis,
articulated chassis and semitrailers.
This standard does not apply to forklifts, floor sweepers, polishers, tow tractors, elevating
work platforms and industrial stationary engines and to other CNG usage, such as the gas
supply system for appliances in caravans, mobile homes or for the propulsion of marine craft.
This standard does not cover the areas where major structural modifications are to be carried
out to the vehicle. Prior to commencement of such work guidance should be sought from the
vehicle manufacturer or a professional engineer who is experienced in the automotive
disciplines.
