This test method covers a laboratory procedure for determining the strength and characteristics of the peel properties of a cured-in-place elastomeric joint. ASTM C (C) determines the strength and characteristics of the peel properties of a cured-in-place elastomeric joint sealant, single- or multicomponent.

ASTM C addresses silicone sealant joints in concrete construction. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
This test, as it exists, does not consider the modulus of elasticity, nor amount of stress that will be produced by a given strain in an actual sealant in a moving joint. Nevertheless, this test provides a valuable measurement of the ability of the cured sealant to maintain a bond to the substrate under severe peel conditions.
The peel test is configured with a degree peel angle.
ASTM C794 Adhesion-in-Peel Elastomeric Joint Sealants Test Equipment
Have a question about conducting the test for this standard? The adhesive force that determines if a given sealant is useful in a given application also depends on the modulus of elasticity and the degree asgm which the sealant will be strained.
By means of our testing expertise and modular product design, we will help find the solution that is right for you.

ASTM C – 18 Standard Test Method for Adhesion-in-Peel of Elastomeric Joint Sealants
It is important to note that a cohesive failure is not necessarily better than an adhesive failure, if the adhesive value is sufficient for the application. Having adhesive failure allows one to study the change of adhesion with time and with the various stress conditions. ASTM C C determines the strength and characteristics of the peel properties of a cured-in-place elastomeric joint sealant, single- or multicomponent, for use in building construction.
