1.1 This practice covers methods to determine the influence of time and stress on a material's oxygen compatibility.
1.2 This practice addresses both methods that have a foundation of experience and potential methods that have yet to be verified for validity, the latter are included to promote research and later elaboration in this practice as methods of the former type.
1.3 The values stated in SI units are to be regarded as the standard, however, all numerical values must also be cited in the systems in which they were actually measured.
1.4 This standard does not purport to address all of the safety problems, 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. Specific precautionary statements are given in Section 9.
