ASTM G 63 Document Information:
Title
Standard Guide for Evaluating Nonmetallic Materials for Oxygen Service
ASTM International
Publication Date:
Mar 10, 1999
Scope:
This guide applies to nonmetallic materials, (hereinafter called
materials) under consideration for oxygen or oxygen-enriched fluid
service, direct or indirect, as defined below. It is intended for
use in selecting materials for applications in connection with the
production, storage, transportation, distribution, or use of
oxygen. It is concerned primarily with the properties of a material
associated with its relative susceptibility to ignition and
propagation of combustion; it does not involve mechanical
properties, potential toxicity, outgassing, reactions between
various materials in the system, functional reliability, or
performance characteristics such as aging, shredding, or sloughing
of particles, except when these might contribute to an
ignition.
When this document was originally published in 1980, it
addressed both metals and nonmetals. Its scope has been narrowed to
address only nonmetals and a separate standard Guide G 94 has been
developed to address metals.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use.
NOTE 1—The American Society for Testing and Materials takes no
position respecting the validity of any evaluation methods asserted
in connection with any item mentioned in this guide. Users of this
guide are expressly advised that determination of the validity of
any such evaluation methods and data and the risk of use of such
evaluation methods and data are entirely their own
responsibility.
NOTE 2—In evaluating materials, any mixture with oxygen
exceeding atmospheric concentration at pressures higher than
atmospheric should be evaluated from the hazard point of view for
possible significant increase in material combustibility.
