ASTM C794 PDF

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 C794 Adhesion-in-Peel Elastomeric Joint Sealants Test Equipment

The peel test is configured with a degree peel angle. G Series Pneumatic Grip. 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. 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.

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.

ASTM C Adhesion-in-Peel Elastomeric Joint Sealants Test Equipment

Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more. Rated to N lbf Maximum specimen thickness of 6 mm 0.

Historical Version s – view previous versions of 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 to which the sealant will be strained. Having adhesive failure allows one to study the change of adhesion with time and with the various stress conditions.

No known correlations are given to relate and apply modulus values to the peel values. ASTM C addresses silicone sealant joints in asrm construction.

Asm 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. 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.

This test is especially useful for quality measurements comparing batches of the same sealant relative to adhesion or for studying adhesion of a given sealant to a variety of substrates.
