In selecting or developing a carpet adhesive, it is critical to have knowledge regarding how well the adhesive will bond to the desired underlayment. Shear loading simulates a common failure mode.

The test method determines the failure shear load for the test adhesive and specific underlayment combination.

1.1 This test method describes a procedure to measure shear strength development for adhesives used to bond carpet adhesives to selected underlayments.

1.2 This test method provides a quantitative means of measuring and recording shear strength of the adhesive when it is applied to the desired underlayment.

1.3 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.

1.4 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.
