ASTM C1311-14 PDF Download

ASTM C1311-14 is a standard specification that outlines the properties of one-component solvent release sealants used in building construction. These sealants are designed to withstand a specified maximum joint movement in extension and compression of the nominal joint width. The standard includes various physical property tests that the sealants must undergo to ensure their quality.

The physical properties that the sealants are expected to conform to include extrudability after aging, shore A hardness, indentation hardness, bubbling, adhesive and cohesive loss after cyclic movement, slump, stain index, tack-free time, and accelerated weathering (edge cracking, center cracking, adhesion loss, and color change). These tests ensure that the sealants can effectively seal joints and maintain their performance over time.

It should be noted that not all sealants meeting this specification are suitable for all applications and substrates. The standard does not imply that all sealants meeting this specification are equivalent in all physical properties. Therefore, it is important to refer to Guide C1193 for information on the proper use of sealants that meet this specification.

This standard is specific to one-component solvent release sealants used in building construction and currently has no similar specification within ISO or any other organization.
