0 Introduction
These implementation rules are established based on the safety risks and conformity assessment risks associated with electric wires and cables, and set out the basic principles and requirements for implementing compulsory certification for them.
These implementation rules shall be applied in conjunction with the following general implementation rules issued by the National Certification and Accreditation Administration (CNCA), including: the Compulsory Certification Implementation Rules — Classification Management of Production Enterprises, Selection and Determination of Certification Modes; the Compulsory Certification Implementation Rules — Utilization of Production Enterprises’ Testing Resources and Other Certification Results; the Compulsory Certification Implementation Rules — Factory Quality Assurance Capability Requirements; the Compulsory Certification Implementation Rules — General Requirements for Factory Inspection etc.
Designated Certification bodies shall develop detailed rules for certification implementation based on the requirements specified in these implementation rules and the general implementation rules, and implement the detailed rules in conjunction with these implementation rules and the general implementation rules.
The production enterprises shall ensure that the certified products they produce meet the certification requirements continuously.
1 Scope
These implementation rules apply to electric wires and cables falling within the scope of the China Compulsory Certification (CCC) Catalogue.
Any adjustment to the scope resulting from changes in laws, regulations, standards, industrial policies, etc., shall be subject to documents issued by the CNCA.
2 Standards for Certification
In principle, the current valid versions published by the national standardization authority shall be applied for the above standards.
3 Certification Mode
The basic certification mode for compulsory certification of electric wires and cables is:
Type testing + post certification surveillance
The post-certification surveillance above refers to one of the following three methods: follow-up inspection after certification, sample testing or inspection from the production site, or sample testing or inspection from the open market.
Designated certification bodies shall implement classification management of production enterprises in accordance with the requirements of the Compulsory Certification Implementation Rules — Classification Management of Production Enterprises, Selection and Determination of Certification Modes, and may, based on the classification management results, add relevant elements such as an initial factory inspection as appropriate to the basic certification mode, and combine the various post-certification surveillance methods, to determine the certification mode applicable to the certification applicant.
4 Certification Unit Division
In principle, certification units shall be divided by product type, model designation, etc. (see Annex for details).
Where identical products are produced by the same production enterprise but under different manufacturers, type testing may be performed on samples from only one unit; for products under other manufacturers, documentation shall be provided for consistency verification.
Designated certification body shall, in accordance with the relevant CNCA provisions and the Annexes to these implementation rules, and taking into account the classification management of production enterprises, specify detailed requirements for unit division in their detailed rules for certification implementation.
5 Certification Application
5.1 Submission and Acceptance of Certification Application
The certification applicant shall submit the certification application to the certification body in an appropriate manner. The certification body shall process the application and provide feedback on acceptance or non acceptance within the timeframe specified in its detailed rules for certification implementation.
Designated certification bodies shall not accept applications that do not comply with the requirements of national laws, regulations or relevant industrial policies.
5.2 Certification Application Documentation
Designated certification bodies shall specify, in its detailed rules for certification implementation, a list of required documentation for certification application based on laws, regulations, standards, and certification implementation requests (including at least the certification application form or contract, proof of registration of the applicant/manufacturer/enterprise, etc.)
For production enterprises not subject to an initial factory inspection during certification, the applicant shall submit a self-evaluation report on the factory’s quality assurance capability.
The certification applicant shall provide all required documentation as specified in the detailed rules for certification implementation. The designated certification body is responsible for reviewing, managing, retaining, and maintaining the confidentiality of such documentation, and shall inform the applicant of the documentation review results.
5.3 Implementation Arrangements
Designated certification bodies shall agree with the applicant on the respective responsibilities and arrangements for each stage of certification implementation. Based on the manufacturer's actual situation and the classification results, designated certification bodies shall determine the specific implementation plan in accordance with these implementation rules and the detailed rules for certification implementation, and notify the applicant accordingly.
6 Certification Implementation
6.1 Type Testing
6.1.1 Type Testing Plan
After completing the documentation review, the certification body shall develop a type testing plan and inform the certification applicant.
The type testing plan shall include all sample requirements and quantities, test items and standards, and laboratory information, etc.
6.1.2 Type Testing Sample Requirements
The certification body shall specify the requirements for sample submission or sampling for type testing in its detailed rules for certification implementation. Typically, samples for type testing shall be selected and submitted by the certification applicant as representative samples for testing based on the requirements of the designated certification body. If necessary, the designated certification body may also obtain samples through on-site sampling/sealing.
The certification applicant shall ensure that the samples provided are consistent with products actually manufactured. The designated certification body and/or laboratory shall verify the authenticity of the samples provided. If the designated laboratory has doubts about the sample authenticity, it shall inform the designated certification body and take appropriate action.
Designated certification bodies shall, in accordance with relevant CNCA provisions, specify in its detailed rules for certification implementation, the list of critical components and materials used in the product, along with related requirements.
For critical components and materials purchased domestically that are within the scope of compulsory certification, the product enterprise shall provide valid compulsory certification certificates. For critical components and materials not subject to compulsory certification, the designated certification body shall specify in its detailed rules for certification implementation the conditions and detailed requirements under which voluntary certification certificates or type testing reports acceptable or recognizable.
6.1.3 Type Testing Items
In principle, type testing shall cover all applicable items specified in the product standards.
