Significado e uso
3.1 Tests of the type described in this practice may be used to assess the corrosion resistance of organic coatings to metal products exposed to high salt environments, such as areas subjected to deicing salts or coastal areas. Exposure conditions are complex and variable. Important factors include climate, time of year, presence of pollution, etc.. It is often difficult, if not impossible, to precisely define or measure all the factors that influence degradation. Exposure tests need to be repeated over different seasons and a period of at least two years to obtain results representative of any given location.

3.2 A control sample should always be used as this is a comparison test.

Prática padrão ASTM D6675-01-2015 para testes de corrosão externa acelerada por sal de produtos cosméticos para revestimentos orgânicos em placas de aço automotivas

Etapa 1: Escopo
1.1 This practice is intended to assist in the procedures that should be followed for outdoor exposure to assess the possible cosmetic corrosion of steel plates covered with organic coatings. The outdoor exposure described is based on practice G7 and includes regular wetting of the test sample with a salt solution.

1.2 The method of specimen preparation and the special exposure requirements of the material are beyond the scope of this practice.
