Comparison of long term exposure (6 years) in C5-M condition and laboratory test for naval industry

摘要

Due to constraints in environmental legislation (i.e. REACH, VOC...), it is necessary to develop suitable methods for the evaluation and the qualification of new protective paint systems. In particular, the need is high for investigating the protection performance of paint systems used in aggressive environments, such as environments of corrosivity category C5-M. The investigating method should be sensitive and relatively quick, give reproducible results and correctly discriminate painted systems. This paper presents results obtained by comparison the results of accelerated test with a natural aging after 6 years of outside exposure in C5-M condition and laboratory test (high durability). The evaluation technique as well as the criteria used for the acceptance of the aging test is discussed.
