Inorganic Coatings – Cleaning of Metal Surfaces – Part 2: Non-Ferrous Metals. ISO 27831-2:2008 outlines guidelines for cleaning non-ferrous metal surfaces, such as aluminum, copper, and their alloys. Cleaning is a critical step before applying coatings to ensure proper adhesion and corrosion resistance. The standard describes various cleaning methods, including chemical treatments and mechanical removal of contaminants, and how to evaluate cleaning effectiveness. It is intended for manufacturers preparing non-ferrous metals for subsequent processing or coating, ensuring the cleaning process is performed consistently.
