ASTM C1311-22 PDF Download

The ASTM C1311-22 standard outlines the properties and testing requirements for one-component solvent release sealants used in building construction. These sealants are specifically designed to withstand a maximum joint movement of 7.5% in both extension and compression of the nominal joint width.

The standard specifies various physical properties that the sealants must meet. These 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). By testing these properties, the sealants can be evaluated for their suitability and durability in various construction applications.

It is worth noting that there is no similar specification within ISO or any other organization that the committee with jurisdiction over this ASTM standard is aware of. This indicates that the ASTM C1311-22 standard is unique and distinct in its requirements and testing methods for solvent release sealants used in construction.
