Standard Test Method for T-Peel Strength of Hot Applied Sealants (Withdrawn 2006)

SCOPE
1.1 This test method covers a laboratory procedure for determining the peel strength of a hot-applied sealant, hereafter referred to as the sealant, when installed between flexible metal substrates of a T-type configuration. It also provides information on the adhesion of the sealant to the tested substrates.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.3 The committee having jurisdiction for this specification is not aware of any similar ISO standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
WITHDRAWN RATIONALE
This test method covers a laboratory procedure for determining the peel strength of a hot-applied sealant, hereafter referred to as the sealant, when installed between flexible metal substrates of a T-type configuration. It also provides information on the adhesion of the sealant to the tested substrates.
This test method is being withdrawn with no replacement because of limited use by the industry, lack of support for the technology and old technology.
Formerly under the jurisdiction of Committee C24 on Building Seals and Sealants, this test method was withdrawn in January 2006.
