NFPA 52-2023 PDF Download

The NFPA 52-2023 standard is a comprehensive guide that outlines the requirements for designing, installing, operating, and maintaining compressed natural gas (CNG) and liquefied natural gas (LNG) fuel systems for vehicles. This standard is essential for various professionals, including designers, engineers, maintenance professionals, facilities managers, contractors, and authorities having jurisdiction.

The standard covers a wide range of topics related to CNG and LNG fuel systems, including fuel compression, processing, storage, and dispensing systems. It also includes guidelines for CNG residential and non-residential fueling facilities, LNG fueling facilities, LNG fire protection, installation of ASME tanks for LNG, and the use of LNG and CNG on commercial marine vessels and pleasure craft.

The 2023 edition of NFPA 52 has undergone revisions, including the extraction of bulk plant requirements from NFPA 59A, as these requirements typically do not apply to NFPA 52 installations. Additionally, the new edition has added the definitions of terms such as defueling and manifold to provide clarity throughout the standard. Container protection requirements have also been revised to align with ASME containers that use pressure relief valves instead of pressure relief devices.
