30、r Natural Gas Fuel Systems Code 2016 Edition This edition of NFPA 52, Vehicular Natural Gas Fuel Systems Code, was prepared by the Technical Committee on Vehicular Alternative Fuel Systems. It was issued by the Standards Council on April 6, 2016, with an effective date of April 26, 2016, and superse

31、des all previous editions. This edition of NFPA 52 was approved as an American National Standard on April 26, 2016. Origin and Development of NFPA 52 While compressed natural gas (CNG) vehicles have been used extensively in other countries since the late 1940s, it was not until the late 1970s that t

32、heir use in the United States became extensive enough to warrant preparation of a national standard. Between 1980 and 1982, a committee of the American Gas Association (AGA) developed a draft of a re safety standard for vehicular fuel systems. This was based on existing worldwide standards and curre

33、nt U.S. practice. In late 1981, the AGA petitioned the NFPA to establish a technical committee project on the subject. The normal NFPA solicitation of comments revealed sufcient response from various interested parties, and the Committee on Compressed Natural Gas Vehicular Fuel Systems was establish

34、ed by the Standards Council in July 1982. The rst edition of NFPA 52, Standard for Compressed Natural Gas (CNG) Vehicular Fuel Systems, was issued in 1984, and it was revised in 1988, 1992, 1995, and 1998. The 2002 edition of NFPA 52 contained minor revisions, most of these in the chapter on engine

35、fuel systems. There also were some changes made to comply with the NFPA Manual of Style for technical committee documents. The most signicant of these were reordering of chapters and numbering of denitions. The 2006 edition of NFPA 52 was a complete revision. NFPA 57, LNG Vehicular Fuel Systems Code

36、, was incorporated into NFPA 52. Additionally, the scope of the committee was expanded to include hydrogen, and new chapters were added that addressed general gaseous hydrogen requirements and equipment qualications; service and maintenance of gaseous hydrogen engine fuel systems; gaseous hydrogen c

37、ompression, gas processing, storage, and dispensing systems; and liqueed hydrogen fueling facilities. The 2010 edition of NFPA 52 revised the committee scope so that it better coordinated with the responsibilities of NFPA 55, Compressed Gases and Cryogenic Fluids Code, with regard to hydrogen storag

38、e systems. A large number of changes were also made to the chapters concerning hydrogen, to update to current material in NFPA documents, the Manual of Style for NFPA Technical Committee Documents, and acceptable performance criteria. Paragraphs extracted from NFPA 55 were shown with the extract ref

39、erence in brackets at the end of the paragraph. In some cases, modications were made to the extracted text to use terminology appropriate for this standard, such as the term cryogenic uid instead of compressed gas. In those instances, brackets encased the modied terms. The 2013 edition removed the r

40、equirements for hydrogen systems, the responsibility for which were transferred to NFPA 2, Hydrogen Technologies Code. A chapter on general fueling requirements was added, and changes were made to the onboard gas detection requirements for LNG-fueled vehicles. The installation requirements for ASME

41、Tanks for LNG were updated to coordinate with NFPA 59A, Standard for the Production, Storage, and Handling of Liqueed Natural Gas (LNG).VEHICULAR NATURAL GAS FUEL SYSTEMS CODE 52-2 2016 Edition The 2016 edition has been completely reorganized for easier access to requirements. The title of the docum

42、ent has been changed from Vehicular Gaseous Fuel Systems Code to Vehicular Natural Gas Fuel Systems Code to coordinate with the removal of hydrogen systems from the scope of the document in 2013. New and revised denitions harmonize the Code with the new CSA Group NGV 5.1 standard, Residential Fuelin

43、g Appliances. Most notably, this includes a new denition for residential fueling appliances and a revised denition for vehicle fueling appliances.COMMITTEE PERSONNEL 52-3 2016 Edition Technical Committee on Vehicular Alternative Fuel Systems Nancy C.
