You may need to comply with this standard if you intend to carry out gasfitting work on consumer gas installations. Gas installations include any appliance, pipes, fittings or other apparatus installed or to be installed for or for purposes incidental to the conveyance, control, supply or use of gas.
This standard specifies requirements for LP gas fuel systems for engines mounted on motor vehicles, either for the propulsion of the vehicle or for driving some auxiliary function (for example, a mixer or a pump). It provides requirements for the design and construction of component parts, for their installation in vehicles, and for tests, commissioning, and periodic inspection.
