(Test Method)Standard Test Method for Heat Resistance of Hot-Applied Sealants Under Dead Load Shear
Standard Test Method for Heat Resistance of Hot-Applied Sealants Under Dead Load Shear
SCOPE
1.1 This test method covers a laboratory procedure for determining the heat resistance of hot-applied sealants, herein referred to as sealant. This test method is conducted under dead load in a shear mode.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.3 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.
1.4 The subcommittee with jurisdiction of this standard is not aware of any similar or equivalent ISO standard.
