Standard Test Method for Lap Shear Strength of Sealants
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This test method covers a laboratory procedure for determining the lap shear strength of sealants. It also provides information on the adhesive bond of the sealants to the tested substrates.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
1.4 The subcommittee with jurisdiction of this standard is not aware of any similar or equivalent ISO standard.
Significance and Use
Sealants are generally subjected to longitudinal and lateral shear stresses in end use applications. This test method measures the cohesive strength of sealants when subjected to shear stresses, and also provides information regarding the adhesive bond to the substrates being tested.
