ASTM D950

Adhesives can fail under a sudden impact load and not under a slowly applied load of the same or greater force.

This test method can be used to compare the sensitivity of various adhesives to suddenly applied loads.

1. Scope

1.1 This test method covers the determination of the comparative impact strength of adhesive bonds in shear, when tested on standard specimens under specified conditions of preparation, conditioning, and testing.

1.2 The values stated in SI units are to be regarded as the standard. The values 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.
