ASTM D263 is the standard specification for chromium oxide green pigment established by the American Society for Testing and Materials (ASTM International), serving as the authoritative basis for global chromium oxide green quality assessment. Products complying with ASTM D263 demonstrate that key indicators including purity, particle size, and color meet internationally recognized standards.
