This specification describes the properties of one-component solvent release sealants for use in building construction. These sealants are generally formulated to withstand a specified maximum joint movement in extension and compression of the nominal joint width. The sealants shall be tested, and is expected to conform to the following physical properties: 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).
1.1 This specification describes the properties of a one-component solvent release sealant for use in building construction. These sealants are generally formulated to withstand a maximum joint movement of 7.5 % in extension and 7.5 % in compression of the nominal joint width.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The committee with jurisdiction of this specification is not aware of any similar specification within ISO or any other organization.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
