1.1 This practice covers compression test in which the specimen is heated to a constant and uniform temperature and held at temperature while an axial force is applied at a controlled rate of strain.

1.2 In metals with extremely high proportional limit or low modulus of elasticity, 1.5 % total strain under load could be reached before the 0.2 %-offset yield strength is reached. In this event the end point of the test may be reported as the 0.2 percent-offset yield strength unless rupture occurs before that point.

1.3 For acceptable compression tests it is imperative that the specimens not buckle before the end point is reached. For this reason the equipment and procedures shall be designed to maintain uniform loading and axial alignment.

1.4 Preferred conditions of testing are recommended so that data from different sources conducting the tests will be comparable.

1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
