Standard Test Method to Evaluate Adhesion/Cohesion Properties of a Sealant at Fixed Extension

Importancia y uso:

5.1 In any sealant application, the sealant must be capable of maintaining an adhesive bond to the substrate when held in strain for its intended service life.

5.2 This test method is an indicator of a sealant’s ability to adhere under strain to a given substrate.

5.3 The default test strain is the movement ability (Class in accordance with Specification C920) of the sealant as designated by the manufacturer. The default joint configuration is 12.7 mm by 12.7 mm by 50.8 mm (¹/₂ in. by ¹/₂ in. by 2 in.). Other strains and joint configurations may be used and reported as noted in Section 8 and Table 1.
