1、Designation: C 1330 02 (Reapproved 2007)Standard Specification forCylindrical Sealant Backing for Use with Cold Liquid-Applied Sealants1This standard is issued under the fixed designation C 1330; the number immediately following the designation indicates the year oforiginal adoption or, in the case
2、of revision, the year of last revision. 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 covers the basic requirements forcylindrical sealant backing to be used w
3、ith cold liquid appliedsealants for use in building seals.1.2 Cylindrical sealant backing serves one or more of thefollowing functions:1.2.1 Limits the amount and depth of sealant applied into ajoint,1.2.2 Acts as a bond breaker to allow joint movementwithout undue stress to the sealant,1.2.3 Provid
4、es a form to assist the sealant in developing theproper shape factor, and1.2.4 Acts as a barrier to the flow of sealant through thejoint.1.3 The committee with jurisdiction over this standard is notaware of any comparable standards published by other ASTMcommittees or other organizations.1.4 This sp
