NFPA adheres to the policy of the American National Standards Institute (ANSI) regarding the inclusion of patents in American National Standards (“the ANSI Patent Policy”), and hereby gives the following notice pursuant to that polic

20、y: NOTICE: The users attention is called to the possibility that compliance with an NFPA Standard may require use of an invention covered by patent rights. NFPA takes no position as to the validity of any such patent rights or as to whether such patent rights constitute or include essential patent c

21、laims under the ANSI Patent Policy.

NFPA 53 Recommended Practice on Materials, Equipment, and Systems Used in Oxygen-Enriched Atmospheres 2016 Edition This edition of NFPA 53, Recommended Practice on Materials, Equipment, and System

31、s Used in Oxygen- Enriched Atmospheres, was prepared by the Committee on Oxygen-Enriched Atmospheres. It was issued by the Standards Council on November 14, 2015, with an effective date of December 4, 2015, and supersedes all previous editions. This edition of NFPA 53 was approved as an American Nat

32、ional Standard on December 4, 2015. Origin and Development of NFPA 53 Development of NFPA 53 was initiated in 1965 largely as a result of interest in the area of oxygen- enriched atmospheres by the aerospace industry and medical personnel/researchers, who expressed a need for a single source of gene

33、ral data on the hazards of oxygen-enriched atmospheres. The rst edition was published in 1969 under NFPA procedures that did not require Association meeting action for NFPA documents. A second edition was formally adopted under NFPA procedures at the NFPA Annual Meeting in 1974. Subsequent editions

34、were adopted in 1979, 1985, 1990, and 1994. The 1994 edition reected a complete review of the contents of the document and incorporated much new information gained by research at the National Aeronautics and Space Administration from 1984 to 1994. The 1999 edition changed the document from a guide t

35、o a recommended practice. Also, some minor changes were made to the denitions of oxygen-enriched atmosphere and ignition temperature. The 2004 edition of the recommended practice underwent editorial revisions to meet the NFPA Manual of Style and included only minor editorial changes. The 2011 editio

36、n reconrmed the provisions as they were written in the 2004 edition. The 2016 edition adds heat of combustion and auto-ignition temperature data to the expanded table of nonmetallic materials for oxygen service. In addition, new re experience reports have been added to Annex D.MATERIALS, EQUIPMENT,
