Significance and Use | ||||
Weight loss from a sealant after application in a building joint can be detrimental to long term sealant durability. A sealant's service life will be shortened if it contains components, critical to its durability, that are volatilized by high environmental temperatures. Also, development of cracks and chalking lessens a sealant's service life. The test described herein measures weight loss, cracking, and chalking. The amount of weight lost during the heat aging period and any cracking or chalking helps predict premature sealant failure. However, a sealant developing no cracks or chalking, or low weight loss in this test, does not necessarily ensure good durability. |

1. Scope | ||||
1.1 This test method covers a laboratory procedure for determining the effects of heat aging on weight loss, cracking and chalking of elastomeric joint sealants (single and multicomponent) for use in building construction. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are 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. |
