GB standards are the Chinese national standards issued by the Standardization Administration of China (SAC), the Chinese National Committee of the ISO and IEC. GB stands for Guobiao (simplified Chinese: 国标; traditional Chinese: 國標; pinyin: Guóbiāo), Chinese for national standard.
Mandatory standards are prefixed "GB". Recommended standards are prefixed "GB/T" (T from Chinese language 推荐 tuījiàn, "recommended"). A standard number follows "GB" or "GB/T".
GB standards are the basis for the product testing which products must undergo during the China Compulsory Certificate (CCC) certification. If there is no corresponding GB Standard, CCC is not required.
A non-exhaustive list of National Standards of the People's Republic of China is listed as follows, accompanied with similar international standards of ISO, marked as identical (IDT), equivalent (EQV), or non-equivalent (NEQ).
