The purpose of this standard Test Method is to provide guidance on the testing and evaluation of coatings for aerospace applications. This Test Method has been developed for use by researchers, manufacturers, and organizations responsible for the manufacture, specification, and use of corrosion protective coatings for aerospace structures. The Test Method details measurement techniques to continuously monitor the combined environmental and mechanical effects that drive coating degradation in laboratory tests. While for many industries, judgements of coating performance may be primarily aesthetic, this Test Method describes direct, continuous measurements of coating degradation processes that are important to aircraft structural integrity.
