Historical Standard: ASTM F1276-99(2003) Standard Test Method for Creep Relaxation of Laminated Composite Gasket Materials
SUPERSEDED (see Active link, below)
ASTM F1276
1. Scope
1.1 This test method provides a means of measuring the amount of creep relaxation of a laminated composite gasket material at a predetermined time after a compressive stress has been applied.
1.2 Creep relaxation is measured by means of a calibrated bolt with dial indicator.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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.
