Standards GB are Chinese national standards, which are issued by China's Standardization Administration Office (SAC).
Chinese national standards are used all over China commonly labeled as GB standards. They determine the united production requirements regarding product safety and quality .
GB standards are often modified or created according to the international standards of ISO, IEC or any other international level.
Although, they are largely harmonized, GB standards may differ from international standards .
Approximately 15% of all GB standards are obligatory and they can be identified according to the prefix GB, after which the code of the standards follows:
GB – Obligatory national standards
GB/T – Optional national standards
GB/Z – National steering technical document
