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
(2) Final-stage vehicle integrator/manufactu
(3) Vehicle fueling (dispensing) systems
Vehicles and fuel supply containers complying with federal motor vehicle safety standards 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 Section 4.4, 4.8.4, and Chapter 6 (except Section 6.11, 6.12.4, 6.13, and Section 6.14).
This code shall apply to the design, installation, operation, and maintenance of compressed hydrogen (GH2), liquefied compressed hydrogen (LH2), and blends of hydrogen up to 20 percent with the balance natural gas (NG) vehicle fueling (dispensing) systems and engine fuel systems and facilities.
This code shall apply to the design and installation of engine fuel systems up to 3600 psi (25 MPa) for vehicles operating on mixtures of GH2 up to 20 percent with the balance natural gas (NG). These blends shall be treated as CNG.
This code shall apply to the design, installation, operation, and maintenance of 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.
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 11, except 11.12.8.
This code shall apply to testing, service, and maintenance of GH2 engine fuel systems.
Vehicles that meet FMVSS requirements for hydrogen-fueled vehicles shall not be subject to this document.
