1、Designation: C 1281 03Standard Specification forPreformed Tape Sealants for Glazing Applications1This standard is issued under the fixed designation C 1281; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision.

2、 A number in parentheses 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 preformed tape sealants foruse in glazing applications. These materials are generally usedto serve as

3、components of glazing systems. They are intendedto serve as a water and air barrier.1.2 This specification is not intended for preformed foamtape sealants.1.3 The values stated in SI units are to be regarded as thestandard. The values in parentheses are provided for informa-tion purposes only.1.4 Th
