The China Quality Certification Centre (CQC) is a professional third-party certification body approved and established by the Chinese government and recognized by many foreign governments and international authoritative organizations. It is also a national certification body that officially joins the IEC System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres (IECEx), and can issue IECEx certificates and reports. As a first-class quality service body with extensive services and strong technological prowess, CQC also provides various international certification services, and is currently the only Chinese certification body that is qualified to issue IECEE, IECEx and IECRE certificates at the same time.

IECEx equipment certification involves testing of explosion-proof products based on the IEC international standards, audit and continuous supervision of production facilities for explosion-proof equipment, and issuance of IECEx CoC certificates and/or explosion-proof test reports (ExTR), and factory quality assurance reports (QAR). IECEx certificates and reports issued by CQC are recognized by more than 30 countries in the IECEx system, helping enterprises to meet the access requirements of each country and enter the global market. Meanwhile, CQC can provide one-stop services of “IECEx +CCC/CQC certification” including CCC certification for explosion-proof products and CQC mark certification of explosion-proof products like lightning fixtures. This one-stop approach allows for multiple certificates to be acquired through a single application.
