1.2 The term "length change," as used here, is defined as an increase or decrease in a linear dimension of a test specimen which has been caused to change by any factor other than externally applied forces and temperature changes.

1.3 The values stated in inch-pound units are to be regarded as the standard.

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.
