This paper provides an overview of extensive research conducted by the Vinyl Siding Institute (VSI) on the development of new test methods for exterior plastic building products. The purpose of the VSI study was to develop an accelerated testing pro ...

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...

In recent years, cyclic corrosion standards in the automotive industry have encouraged manufacturers of test chambers to offer new control features. Automotive OEMs required these new features in order to simulate actual automotive corrosion and to i...

Reciprocity is the notion that if you increase irradiance in a weathering test, you can decrease your exposure time by a reciprocal amount and still get the same results. Said another way, reciprocity states that the amount of degradation in a weathe...

In LF-8116, "A New Era in Corrosion Testing," we discussed a short history of modern atmospheric corrosion testing and recent advances in the field. In this article we will cover a topic which generates many questions from laboratory technicians and ...
