ASTM D5648-01(2014)

5.1 On some applications of threaded fasteners, it is desirable to control either the amount of developed tension when a specified range of torque has been applied or the torque required to develop a specified range of tension. This test method is used to determine the effect of using adhesives on the torque-tension relationship of threaded fasteners.

5.2 Accurate torque-tension relationships may be measured only by defining and controlling the many related test parameters.

1.1 This test method covers the determination of the torque-tension relationship (lubricity) of adhesives used for locking and sealing threaded fasteners.

1.2 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.

1.3 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.
