This standard covers the various stages of determining organic coating drying, curing and film formation under controlled temperature and Humidity conditions. With Methods A, B and C it is possible to assess the effect of different temperatures and Humidity on the coating drying rate. This standard is suitable for comparing the drying performance of different coatings, evaluating the effect of composition on drying rate and providing an evaluation procedure for drying in a practical application environment. The standard is suitable for coating drying evaluation in laboratory and real work environment.
