2、 case of revision, the year 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 covers the basic requirements for cylindrical sealant backing to be
3、used with cold liquid applied sealantsfor use in building seals.1.2 Cylindrical sealant backing serves one or more of the following functions:1.2.1 Limits the amount and depth of sealant applied into a joint,1.2.2 Acts as a bond breaker to allow joint movement without undue stress to the sealant,1.2
4、.3 Provides a form to assist the sealant in developing the proper shape factor, and1.2.4 Acts as a barrier to the flow of sealant through the joint.1.3 The committee with jurisdiction over this standard is not aware of any comparable standards published by other ASTMcommittees or other organizations

16、5. Significance and Use5.1 This specification is designed to give some indication as to the differences in performance for various cylindrical sealantbackings.5.2 Although this specification qualifies a cylindrical sealant backing for use, it does not address the compatibility of the backingwith the
17、 sealants with which it will make contact. Sealant compatibility should be confirmed by the sealant manufacturer.Compatibility characteristics of sealants in contact with cylindrical sealant backings can be determined by Test Method C1087.6.
