AbstractThe paper describes experimental work carried out in support of the development of an International Standard on sealant durability. It compares the results of different lab tests, suggested during the development of the Standard, with those obtained from outdoor weathering under mechanical strain. The comparison shows that the 70°C compression test, as included in ASTM C-719, is helpful in identifying sealants which fail due to high compression set. The heat compression test, however, does not rule out sealants that tend to post-cure or embrittle upon ageing. The best correlation between lab tests and outdoor weathering is obtained if the sealants are allowed to cure fully prior to lab testing.
