China Railways Test and Certification Center (CRCC, Chinese: 中铁检验认证中心) is responsible for certifications of railway products for the Chinese market.
Until 2003 the state-owned enterprise was named Railways Product Certification Center.
Afterwards the application documents for the respective products have to be handed in at the CRCC.
If all product tests are completed successfully, Chinese inspectors will visit the manufacturing site for a 2-day audit.
After the factory audit, the CRCC will issue a Certificate of Approval.
