The “China Compulsory Certification (CCC)” is a certification system of the People’s Republic of China. Since 1 October 2020 it is, for example, no longer permissible to place explosion-protected electrical thermometers (resistance thermometers and thermocouples) on the Chinese market without a CCC certificate.
Introduced on 1 May 2002, the CCC certification system applies to imported and also to Chinese products. The import, sale and use of products requiring certification is not permitted in China without a CCC certificate. This means that products without this certification are detained at the border or returned by the Chinese authorities.
Examples of electrical thermometers
Product certification
A CCC product catalogue shows which products require appropriate certification. Explosion-protected resistance thermometers and thermocouples are listed in this catalogue, and therefore certification of these measuring instruments is necessary.
After registering for certification, detailed application documents must be submitted to the Chinese approval authority. Laboratory tests of the products in China follow.
Factory inspection
The production facility must also undergo certification. This is carried out by means of a factory inspection by the certification authority (factory audit).
Period of validity
Permission to apply the CCC mark to the successfully certified product is valid for five years – but only if an annual refresher certification is carried out.
Successful testing and auditing at WIKA
Various resistance thermometers, thermocouples and also other products from WIKA are already CCC-certified. Likewise, many WIKA production sites have already successfully passed the audit. Therefore, there is nothing to prevent the certified measuring instruments from being used in China.
Note
Further information on resistance thermometers and thermocouples can be found on the WIKA website.
