1、Designation: C 1311 02Standard Specification forSolvent Release Sealants1This standard is issued under the fixed designation C 1311; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses
2、 indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification describes the properties of a one-component solvent release sealant for use in building construc-tion. These sealants are generally form
3、ulated to withstand amaximum joint movement of 7.5 % in extension and 7.5 % incompression of the nominal joint width.1.2 The values stated in SI units are to be regarded as thestandard. The values given in parentheses are for informationonly.1.3 The committee with jurisdiction of this specification
