ASTM C1367-06(2012)

Standard Test Method for Dead Load Resistance of a Sealant in Elevated Temperatures

SIGNIFICANCE AND USE
Sealants are generally subjected to stresses in end-use applications. This test method measures the heat resistance of sealants when subjected to dead load shear stresses while under heat.
SCOPE
1.1 This test method covers a laboratory procedure for determining the heat resistance of sealants. This test method is conducted under dead load in a shear mode. This test method was previously written to include only hot applied sealants.
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.
