1、Designation: C 1281 03 (Reapproved 2009)Standard 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
2、 of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () 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
3、 usedto serve as 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 pur
4、poses only.1.4 The subcommittee with jurisdiction is not aware of anysimilar ISO standard.1.5 The following precautionary statement pertains only tothe test method section of this specification. This standard doesnot purport to address all of the safety concerns, if any,associated with its use. It i
5、s the responsibility of the user of thisstandard to establish appropriate safety and health practicesand determine the applicability of regulatory limitations priorto use.2.
