Standard Test Method for Yield Strength of Preformed Tape Sealants

Significance and Use

4.1 Tape sealants are tacky, deformable solids that are used under compression between two or more surfaces of similar or dissimilar materials in a variety of sealing applications. This procedure is not intended to simulate an actual use condition but will give some indication of the cohesive and adhesive bonding properties of the tape. It also provides an indication of the modulus and tensile strength of the sealant tape composition.


1.1 This test method covers a laboratory procedure for determining the yield strength of preformed tape sealants.

1.2 The values stated in acceptable metric 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.

Note 1: There are no ISO standards similar or equivalent to this ASTM standard.
