Guobiao standards or 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 or 3C) 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).
