ASTM C907-17 (R2018) PDF Download

ASTM C907-17 (R2018) is a standard test method that determines the tensile adhesive strength of preformed tape sealants using the disk method. Preformed tape sealants are sticky, deformable materials used for sealing applications between different surfaces. This test method measures the tensile strength of the preformed tape sealant and evaluates its cohesive nature and adhesive bonding properties. It is important to note that this test does not mimic actual use conditions.

The procedure outlined in this standard provides a laboratory-based method for assessing the tensile adhesive strength of preformed tape sealants. It allows for determining the type of failure that occurs and provides an estimation of the degree of cohesive and adhesive failure. The standard specifies that metric (SI) units are to be used as the standard, with values given in parentheses provided for informational purposes only.

The subcommittee responsible for this standard is not aware of any similar ISO standard, indicating that this ASTM standard is unique in its approach to testing the tensile adhesive strength of preformed tape sealants.
