This test method is designed to produce shear property data for the process control and specification of adhesives. This test method may also be useful for research and development of adhesives.
Lap shear properties vary with specimen configuration preparation, speed, and environment of testing. Consequently, where precise comparative results are desired, these factors must be carefully controlled and reported.
1.1 This test method covers the determination of the tensile shear strengths of adhesives for bonding metals when tested in an essentially peel-free standard specimen that develops adhesive stress distribution representative of that developed in a typical low-peel production-type structural joint. The reproducibility of the strengths achieved are directly related to conformance with specified conditions of preparation and testing.
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.
