1、Designation: C1311 14Standard Specification forSolvent Release Sealants1This standard is issued under the fixed designation C1311; 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 i
2、ndicates the year of last reapproval. Asuperscript epsilon () 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 formula
3、ted 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 producer is permitted awide latitude in choice of raw materials for making theseproducts. Con
9、sequently, there is no implication that the com-pounds are equivalent in all physical properties.4.3 The manufacturing process shall be such as will ensurea homogeneous mix, free of defects that would affectserviceability, and of a consistency suitable for immediateapplication.5. General Requirement
10、s5.1 Standard ConditionsPerform all of the tests in acontrolled environment at standard conditions. Condition seal-ant samples for at least5hatthese conditions before any testsare performed.5.2 The sealant in the original container shall be suitable foruse for at least 12 months from the date of man
11、ufacture whenstored at a temperature neither below 5C (41.0F) norexceeding 27C (80.6F).5.3 The color of the sealant shall be as agreed upon betweenthe purchaser and the manufacturer.5.4 The sealant shall be intended for use only on clean, drysurfaces. When a primer is recommended by a manufacturerfo
12、r a specific substrate, all tests on that substrate shall includethe primer. The proper use of primers (or surface conditioners)with the application of sealants is described in detail in GuideC1193. This guide also describes proper methods for jointdesign, backup materials, surface preparation, tool
13、ing ofsealant, and other important procedures in sealant applicationin buildings.1This specification is under the jurisdiction of ASTM Committee C24 onBuilding Seals and Sealants and is the direct responsibility of Subcommittee C24.10on Specifications, Guides and Practices.Current edition approved J
