A Database for Metallic and Nonmetallic Materials Commonly Utilized in Oxygen Service

Abstract

This paper presents the design, structure, and use of a materials database for metallic and nonmetallic materials commonly utilized in oxygen service. Also discussed is the need for a widely accessible and easily searched database of materials compatibility test data for general use within the oxygen community. Over the last two decades, the ignition and combustion properties of metallic and nonmetallic materials exposed to oxygen-enriched environments have been widely studied by both government and commercial industry. However, to our knowledge, these data have never been compiled into a comprehensive and easily accessible database for general utilization and cross-comparison. Consequently, collecting the necessary data for hazards analyses on materials and components is difficult and time consuming, when done in accordance with the procedures advanced by ASTM Guide G-63, “Standard Guide for Evaluating Nonmetallic Materials for Oxygen Service,” and ASTM Guide G-94, “Standard Guide for Evaluating Metals for Oxygen Service.” This paper presents a database of materials test data and discusses the utilization of these data in a computerized hazards analysis that generally follows the guidelines of ASTM G-63 and G-94 and the “good practices” of ASTM G-88. The relational structure of the database is presented and the advantages of this type of data structure are discussed.
