1.1 This test method covers a laboratory procedure for determining the weight loss after heat aging of preformed tape sealants.

Note 1Test Method C681 describes a weight loss or volatility test for knife-grade glazing compounds.

1.2 The values stated in acceptable metric units are to be regarded as the standard. The values given in parentheses are for information only.

1.3 The subcommittee with jurisdiction 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.


5.1 Preformed tape sealants are tacky, deformable solids that are used under compression between two substrates in a variety of sealing applications. Compared to other types of sealants, that is, gunnable sealants and caulks, sealing tapes are designed to be essentially 100 % solids materials. In use, these tapes are intended to give long service with minimal weight loss or volatility. This procedure will give a measure of the weight loss of a preformed tape sealant after a controlled period of exposure at an elevated temperature.
