scope:

This code shall apply to the design, installation, operation, and maintenance of compressed natural gas (CNG) and liquefied natural gas (LNG) engine fuel systems on vehicles of all types and for fueling vehicle (dispensing) systems and associated storage, including the following:

(1) Original equipment manufacturers (OEMs)

(2) Final-stage vehicle integrator/manufacturer (FSVIM)

(3) Vehicle fueling (dispensing) systems

This code shall apply to the design, installation, operation, and maintenance of liquefied natural gas (LNG) engine fuel systems on vehicles of all types, to their associated fueling (dispensing) facilities, and to LNG to CNG facilities with LNG storage in ASME containers of 70,000 gal (265 m3) or less.

Vehicles and fuel supply containers complying with federal motor vehicle safety standards (FMVSSs) covering the installation of CNG fuel systems on vehicles and certified by the respective manufacturer as meeting these standards shall not be required to comply with Sections 5.4, 5.8, 5.9, and 5.10 and Chapter 6 (except Sections 6.9, 6.11, 6.12, 6.13, and 6.14).

This code shall include marine, highway, rail, off-road, and industrial vehicles.

Vehicles that are required to comply with applicable federal motor vehicle safety standards covering the installation of LNG fuel systems on vehicles and that are certified by the manufacturer as meeting these standards shall not be required to comply with Chapter 9, except 9.12.8.

Where conflicts occur between provisions of this code and referenced codes and standards, the provisions of this code shall apply. 

Where, in any specific case, different sections of this code specify different materials, methods, or other requirements, the most restrictive shall govern.

Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall be applicable. 

Manufacturer specifications shall equal or surpass the applicable requirements of this code.

Purpose.

The purpose of this code shall be to provide fundamental safeguards against fire and explosion hazards associated with compressed natural gas (CNG) and liquefied natural gas (LNG) engine fuel systems on vehicles of all types and for refueling stations and associated storage.
