Standard Test Method for Effects of Heat Aging on Weight Loss, Cracking, and Chalking of Elastomeric Sealants After Cure
Also Known As:
The ASTM C1246-17 standard is a laboratory test method used to evaluate the effects of heat aging on the weight loss, cracking, and chalking of elastomeric sealants after cure. It is specifically designed for sealants used in building construction.
The purpose of the test is to determine the durability of the sealant by measuring its weight loss, cracking, and chalking after exposure to high environmental temperatures. Weight loss is important because it can shorten the service life of the sealant if critical components are volatilized. Cracks and chalking also negatively impact the sealant's longevity.
The test method described in the standard helps predict premature failure of the sealant by quantifying weight loss, cracks, and chalking. However, it is important to note that a sealant showing no cracks or chalking, or exhibiting low weight loss in this test, does not guarantee good durability.
There is no similar ISO standard mentioned in the specification, indicating that this is a unique and specific ASTM standard for testing the effects of heat aging on elastomeric sealants used in building construction.
