Materials for Oxygen gas duty 5

[GeoffR]

would anyone out there know the best place to get a list of materials suitable for use with oxygen gas ?

ASTM Committee G04 on Compatibility and Sensitivity of Materials in Oxygen-Enriched Atmospheres has published many standards on material for oxygen service. If you purchase a component for oxygen service, the mfr. Should certify compliance with applicable ASTM and CGA standards as well as NFPA articles. Note also cleaning requirements; new & maintainence. Some of the ASTM standards:
G63-99 Standard Guide for Evaluating Nonmetallic Materials for Oxygen Service
G94-92(1998) Standard Guide for Evaluating Metals for Oxygen Service
G88-90(1997)e1 Standard Guide for Designing Systems for Oxygen Service
G93-96 Standard Practice for Cleaning Methods and Cleanliness Levels for Material and Equipment Used in Oxygen-Enriched Environments
G94-92(1998) Standard Guide for Evaluating Metals for Oxygen Service
G114-98 Standard Practice for Aging Oxygen-Service Materials Prior to Ignitibility or Flammability Testing
G121-98 Standard Practice for Preparation of Contaminated Test Coupons for the Evaluation of Cleaning Agents
G127-95(2000) Standard Guide for the Selection of Cleaning Agents for Oxygen Systems
G128-02e1 Standard Guide for Control of Hazards and Risks in Oxygen Enriched Systems
G131-96(2002) Standard Practice for Cleaning of Materials and Components by Ultrasonic Techniques
G136-96(2002) Standard Practice for Determination of Soluble Residual Contaminants in Materials by Ultrasonic Extraction

NASA compiled a bibliography of references of interest to practitioners of oxygen compatibility. It includes every reference in Flammability and Sensitivity of Materials in Oxygen-Enriched Atmospheres: Eighth Volume, ASTM STP 1319, William T. Royals, Ting C. Chou, and Theodore A. Steinberg, Eds., American Society for Testing and Materials (1997), plus several hundred more. Last updated October 22, 2002. At
