NFPA 52     Vehicle Fuel Systems Code     Published      United States
Organization	National Fire Protection Association
Identification	NFPA 52 Vehicular Fuel Systems Code
Scope	This code applies to the design and installation of compressed natural gas (CNG) and liquefied natural gas (LNG) engine fuel systems of vehicles of all types and for refueling stations and associated storage, including the following:       (1)   original equipment manufacturers,       (2)   vehicle converters, and       (3)   vehicle fueling (dispensing) systems. The 2005 edition of this code will also apply to the design and installation of gaseous and liquefied compressed hydrogen vehicle fueling (dispensing) systems and engine vehicle fuel systems.   Note: Indoor Fueling Requirements   a.     9.3.3.13   b.    Mandates use of hydrogen detectors.
Status	Published 2010.  Available at www.nfpa.org. The major changes for this latest edition include:   ·   Synchronization of storage requirements with NFPA 55,   ·   Reorganization of hydrogen requirements,   ·   Indoor fueling requirements rewritten, and   ·   Table 9.3.1.3, Separation Distances for Outdoor Gaseous Hydrogen Systems, will be harmonized with the          corresponding table from NFPA 55 (55:10.3.2.2.1). The NFPA Standards Council voted to remove hydrogen requirements from the scope of NFPA 52. These requirements will now reside in NFPA 2. The 2012 revision cycle has started this process.
