USE OF OXYGEN AND OXYGEN SYSTEMS is sponsored by Committee G4 on Compatibility and Sensitivity of Materials in Oxygen-Enriched Atmospheres The editorial and review work for this edition were coordinated by Sarah R Smith, NASA Johnson Space Center White Sands Test Facility, Las Cruces, New Mexico This edition of the handbook is an extensive revision of the original ASTM Manual 36 This revision includes large structural changes in the document as well as updates to the information and data contained herein This manual contains minimum guidelines; users are encouraged to assess their individual programs and develop additional requirements, as needed “Shalls” and “wills” denote requirements that are mandated by other existing documents, which are referenced v Acknowledgments The original material was contained in the NASA Safety Standard for Oxygen and Oxygen Systems, NSS 1740.15, which established a uniform NASA process for oxygen system design, materials selection, operation, storage, and transportation The NASA document represented a wealth of information, knowledge, and experience gained by NASA and its contractors This information, knowledge, and experience should be extremely valuable to industry, particularly the small or infrequent user of oxygen who has little or no experience and staff to draw upon The NASA Oxygen Safety Handbook was originally prepared under NASA contract by Paul M Ordin, Consulting Engineer The support of the NASA Hydrogen-Oxygen Safety Standards Review Committee in providing technical monitoring of the original standard is recognized The Committee included the following members: William J Brown—NASA Lewis Research Center Frank J Benz—NASA Johnson Space Center Mike Pedley—NASA Johnson Space Center Dennis Griffin—NASA
