Correlation analysis of natural environment test and laboratory accelerated test

Abstract

There is a growing concern about correlation analysis of natural environment test and laboratory accelerated test, especially test about corrosion of metal, nonmetal and coatings. This paper will concentrate on correlation analysis from simulation ability, accelerating ability and reproducibility. As an illustration, exposure test in marine atmospheric environment and salt spray test in laboratory of Parylene C coating were performed. And conclusions were reached that there was satisfactory correlation between these two tests and accelerated ratio was also gained.
