LX-5018 Accelerated Weathering Testing for the 21st Century

Automotive OEMs, coatings material suppliers, and weathering specialists banded together in a series of studies aimed at improving weathering test protocols. After a decade of research, the result is a newly published ASTM test standard, D7869, which has been shown to provide very good correlation to outdoor Florida test results for several failure mechanisms seen in a variety of automotive and aerospace coatings technologies. This new method validates the idea that accelerated testing can accurately replicate the effects of outdoor weathering, but the long path to this result demonstrates that correlating to the natural environment is never a simple proposition.
