Historical Standard: ASTM F38-00 Standard Test Methods for Creep Relaxation of a Gasket Material
SUPERSEDED (see Active link, below)
ASTM F38
1. Scope
1.1 These test methods provide a means of measuring the amount of creep relaxation of a gasket material at a stated time after a compressive stress has been applied.
1.1.1 Test Method A -Creep relaxation measured by means of a calibrated strain gage on a bolt.
1.1.2 Test Method B -Creep relaxation measured by means of a calibrated bolt with dial indicator.
1.2 The values stated in SI units are to be regarded as the standard.
1.3 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.
