Titanium dioxide pigments
1 Scope
This standard specifies the product classification, requirements, test methods, judgment of inspection results, marking, packaging, transportation and storage of titanium dioxide pigments.
This standard is applicable to titanium dioxide pigments produced by sulfuric acid method or chlorination method. This product is mainly used in paints, rubber, plastic, ink and paper making industries.
