12、ystems 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 supersedes all previous edi
13、tions. This document has been amended by one or more Tentative Interim Amendments (TIAs) and/or Errata. See “Codes service and maintenance of gaseous hydrogen engine fuel systems; gaseous hydrogen compression, gas processing, storage, and dispensing systems; and liqueed hydrogen fueling facilities.
14、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 storage systems. A large number of changes were also made to the chapters concerning hydrogen, to update to
15、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 reference in brackets at the end of the paragraph. In some cases, modications were made to the extracted
16、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 requirements for hydrogen systems, the responsibility for which were transferred to NFPA 2, Hydrogen Te
17、chnologies 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 Tanks for LNG were updated to coordinate with NFPA 59A, Standard for the Production, Storage, and Hand
18、ling 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 document has been changed from Vehicular Gaseous Fuel Systems Code to Vehicular Natural Gas Fuel Systems Co
19、de 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 Fueling Appliances. Most notably, this includes a new denition for residential fueling appliances and a revi
20、sed denition for vehicle fueling appliances.COMMITTEE PERSONNEL 52-3 2016 Edition Technical Committee on Vehicular Alternative Fuel Systems Nancy C.
