The ISO 10601:2007 standard defines requirements and test methods for micaceous iron oxide pigments for use in protective coatings for steel structures. The standard describes in detail the composition, Particle size range and particle shape of micaceous iron oxide pigments and specifies their performance requirements in coatings. The standard pays particular attention to the layered particle content of pigments and specifies test methods to ensure the effective protective function of pigments in coatings. This standard provides clear technical specifications for the production and application of micaceous iron oxide pigments.
