In principle, the current valid versions of above standards that are issued by the National Standardization Administration shall be executed. When the above standards are revised, it shall be implemented in accordance with the
requirements of the relevant documents issued by the CNCA.
3??Certification??modes
The basic certification mode of implementing the China Compulsory Certification for explosion-proof electrical products is:
Type test + initial factory inspection + after-certification supervision ?€?After-certification supervision?€? refers to one or a combination of two methods: after-certification follow-up inspection and factory on-site sampling test. The certification body shall follow the requirements of ?€?China Compulsory Certification Implementation Rules - Manufacturing Enterprise Classification Management, Certification Mode Selection and Determination?€? to carry out the classification management to manufacturing enterprise; consider the results of classification management; determine the method and frequency of after- certification supervision; may reduce or exempt the initial factory inspection of the extended product.
4??Division??of??certification??units
In principle, according to the equipment classification, explosion-proof type, product type, explosion-proof structure, and safety parameters of explosion- proof electrical products, the application unit is divided.
For the same product that is of same manufacturer but of different
manufacturing enterprises, or for the same product that is of different manufacturers and of same manufacturing enterprise, it is possible to only conduct the type test on the samples of 1 unit. The products of other
manufacturing enterprises / manufacturers shall provide documents for
conformity inspection.
In accordance with the relevant documents issued by the CNCA, the certification body shall specify the specific requirements for the division of units in the certification implementation detailed-rules.
5??Certification??entrusting
5.1 Application and acceptance of certification entrusting
The certification client puts forward the certification entrusting to the certification body. Certification body shall process the certification entrusting; and feedback the acceptance or rejection according to the time limit in the certification implementation detailed-rules. [TRANSLATOR NOTE is not part of this Rules. Translator note: ?€?certification client?€?, the counterpart of certification body, refers to the Applicant / Manufacturer or its proxy (Power of Attorney). For ease of reading, hereinafter abbreviated as ?€?CLIENT?€?]
When it does not comply with national laws and regulations and relevant industry policies, the certification body must not accept the certification entrusting.
5.2 Application materials
The certification body shall, in accordance with the laws and regulations, standards, and the needs of certification implementation, specify the checklist of application materials in the certification implementation detailed-rules. They shall include at least the certification application or contract, registration certificates of CLIENT / manufacturer / manufacturing enterprise, etc.
CLIENT shall provide the required materials according to the requirements of application material checklist in certification implementation detailed-rules. Certification body is responsible for auditing, managing, preserving and keeping confidential of the relevant materials, and shall inform the CLIENT of the material auditing results.
5.3 Implementation arrangement
The certification body shall agree with CLIENT on the relevant responsibility and arrangement of both parties in each link of certification implementation. And according to the situation of manufacturing enterprise and classification management AND the requirements of this Rules and certification
implementation detailed-rules, DETERMINE the specific program of certification implementation and INFORM CLIENT.

In general, for the sample of type test, representative samples are selected and sent by the CLIENT according to the requirements of the certification body for testing. When necessary, certification body may adopt on-site sampling method to obtain the samples. In the implementation detailed-rules, the certification body shall specify the relevant requirements for sample sending / sampling of certified products.
CLIENT shall ensure that the samples provided by it are consistent with the products actually produced. Certification body and / or laboratory shall inspect the authenticity of the samples provided by the CLIENT. If laboratory has any doubt on the authenticity of the samples, it shall explain the situation to certification body and handle accordingly.
According to relevant documents issued by CNCA, certification body shall, in the certification implementation detailed-rules, define the ?€?product critical components and materials checklist?€? AND relevant requirements.
For critical components and materials within the scope of China Compulsory Certification purchased in China, the manufacturing enterprise shall provide a China Compulsory Certification certificate. For critical components and materials not within the scope of China Compulsory Certification, the certification body shall, in the certification implementation detailed-rules, specify the conditions and specific requirements for voluntary certification certificate or type test report that can be accepted or recognized.
6.1.3 Test items of type test
