National Standards of China

A Chinese standard code has three parts: the prefix, the sequential number, and the year number. For example, GB 2312-1980 refers to the national compulsory standard (GB), sequential number 2312, revision year 1980. Besides the national standard repository, China allows the registration of standards by industry/trade, by localities (DB, Dìfāng Biāozhǔn, "local standard"), by associations (T), or by an individual company (Q). The overall prefix number-year format is retained. == Copyright and availability ==

Under the first clause of Article 5 of the ''Copyright Law of the People's Republic of China'', compulsory standards are not copyrightable as they fall under "other documents of a legislative, administrative or judicial nature". In 1999, the Supreme People's Court ruled that although compulsory standards do not enjoy copyright protections, publishing houses can be given exclusive, sui generis rights to publish a compulsory standard. The Standardization Administration operates a website for obtaining digital copies of the standards (excluding those dealing with food safety, environment protection, and civil engineering). The availability is broken down as follows (as of October 2023): ==List==

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). Changes are made frequently within the Chinese regulatory system as new standards are released and existing standards are updated. == See also ==
