NFPA 52 壓縮天然氣汽車燃料系統規范

1.1* Scope.

1.1.1 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

1.1.2 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.

1.1.3 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 4.4, 4.8, 4.9, and 4.10 and Chapter 6 (except Sections 6.9, 6.11, 6.12, 6.13, and 6.14).

1.1.4 This code shall apply to the design, installation, operation, and maintenance of compressed hydrogen (GH2) and liquefied compressed hydrogen (LH2).

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

1.1.6 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.

1.1.7 This code shall apply to testing, service, and maintenance of GH2 engine fuel systems.

1.1.8 Vehicles that meet FMVSS requirements for hydrogen fueled vehicles shall not be subject to this document.

Apply NFPA 52 for safety in CNG and LNG fuel systems and fueling facilities.

Updated based on recent experience in the field, the 2010 NFPA 52 Vehicular Gaseous Fuel Systems Code presents the latest fire safety rules for hydrogen fuel systems, compressed natural gas (CNG) fuel systems, and liquefied natural gas (LNG) systems on all vehicle types -- plus their respective compression, storage, and dispensing systems. It applies to all facilities with LNG storage in containers of 70,000 gallons or less.

Design, install, operate, and inspect fuel systems and facilities responsibly. The 2010 edition introduces

·    New and revised chapters on gaseous and liquefied compressed hydrogen gas

·    New definitions to avoid confusion and put everyone -- designers, installers, and inspectors -- on the same page

Stay up-to-code with the most trusted guide to CNG and LNG hazards available.

NFPA 52 is developed with widespread input from organizations including the Compressed Gas Association (CGA), Society of Automotive Engineers (SAE), and the National Hydrogen Association (NHA). (Softbound, 101 pp., 2010)
