Examples: "GB/T 14048 vs IEC 60947" • "steel pipe China ASTM" • "fire protection GB EN comparison"
GB and GB/T are China's national standards · the Chinese equivalent of EN (Europe), ASTM (USA), or JIS (Japan). Every product manufactured in China for domestic sale must comply with the relevant GB standard. When you source from China, supplier test reports and certificates will reference these GB numbers, and understanding whether they align with your home-market requirements is critical.
GB standards are formally classified by their relationship to ISO/IEC:
