0.1 Introduction
The implementation regulation on compulsory product certification for electric wires and cables (hereinafter referred to as the "Implementation Regulation") was prepared as per “Implementation Rule on Compulsory Certification - Electrical Wires and Cables” (CNCA-C01-01: 2014) (hereinafter referred to as the "Implementation Rule") as an auxiliary document for certification implementation rules. This Implementation Regulation was prepared and published on the basis of the Implementation Rule as well as the quality manual, procedure documents and operation instructions of the China Quality Certification Center (hereinafter referred to as CQC) and on the principles of maintaining the validity of product certification, improving product quality, serving certification enterprises and controlling certification risk.
This Implementation Regulation was prepared according to and shall apply in combination with the Implementation Rule. Product range and certification basis applicable for the Regulation shall comply with relevant provisions in the Implementation Rule and shall be adapted in accordance with announcements on the definition and adjustment of contents issued by Certification and Accreditation Administration of the People's Republic of China (hereinafter referred to as “CNCA”).
Based on the certification implementation rule, CQC has established requirements for classification management of manufacturers and, in combination with manufacturer classification, specified those for implementation of compulsory product certification for electric wires and cables.
0.2 Terms and Definitions
0.2.1 Testing at Manufacturer's Premises (Hereinafter Referred to as TMP)
Testing conducted by designated personnel from testing body using manufacturer's equipment with the assistance of testing personnel from the manufacturer, of which the testing report is issued by designated testing body.
0.2.2 Witnessed Manufacturer's Testing (Hereinafter Referred to as WMT)
Testing conducted by manufacturer's test personnel using his equipment, with testing items and conditions witnessed by designated personnel from testing body, original record issued by and test report drafted by manufacturer’s test personnel but reviewed and validated by designated personnel from the testing body, and test report issued by designated testing body.
0.2.3 Original Design Manufacturer (ODM)
The factory designing, processing and producing identical products for one or more producers (manufacturers), using identical quality assurance capacity requirements and identical requirements for product design, production process control and inspection.
0.2.4 ODM Initial Certificate Holder
The organization whose ODM products have initially earned product certificate.
0.2.5 Verification on Product Conformity
Product inspection carried out to assess the conformity in safety performance of manufactured goods and to verify the compliance with product standards concerned.
0.3 Principle for Manufacturer Classification
CQC acquires and reorganizes all kinds of information relevant to certification product and its manufacturer quality so as to realize classification management of manufacturer in a dynamic way. Certification client, producer and manufacturer shall coordinate with CQC.
Manufacturers are classified into Category A, Category B, Category C and Category D, according to information at least including:
① Factory inspection (including initial factory inspection and post-certification follow-up inspection) result;
② Testing result of supervision sampling (production site sampling or market sampling);
③ Conclusions on national and provincial random inspections and CCC special random inspection;
④ Quality information feedback from media exposure, product user and the public;
⑤ Certification product's testing capacity;
⑥ Other information.
CQC classifies and grades manufacturers based on the following basic principles for classification; it also, periodically or aperiodically, reclassifies and grades them according to all kinds of information so as to realize dynamic management. The result of manufacturer classification in principle must be upgraded by successive level of D-C-B-A and degraded by successive or cross level of A-B-C-D.
Table 1 Principle for Classification of Manufacturers
Category of enterprise Classification prinicple
Category A Category B provides relevant information for certification authority while the latter makes an integrated risk assessment and determines classification result according to acquired quality information and the information provided by the former. The assessment at least covers the following contents:
a) Factory inspection: initial factory inspection and post-certification follow-up inspection in the last two years are qualified or not verified on site;
b) Results of product testing and random inspection: no non-conformance terms are found in the supervision and inspection within the last 2 years after certified, and the national and provincial quality supervisions and random inspections for all kinds of products as well as conformity verification turn out to be "qualified";
c) Passing the CQC review on the manufacturer's testing capacity or qualified as declared AA enterprise by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China;
d) Other information related to the manufacturer and the quality of certified products.
Category B Other, except Category A, Category C and Category D, manufacturers. As for manufacturers without any quality information, its classification grade is Category B by default.
Category C Meeting any of the following conditions:
a) Manufacturers whose factory inspection conclusion is judged as "on-site verification" (except for the reasons of revised standard);
b) Manufacturers whose certified product is found with quality problem by the media and who are liable but without certificate suspension and cancellation involved;
c) Manufacturers which need to be adjusted to Category C as considered by CQC as per the results of comprehensive assessment on quality information related to the manufacturers and their certified products.
Category D Meeting any of the following conditions:
a) The initial factory inspection and post-certification follow-up inspection are judged as "No pass";
b) Safety in post-certification supervision is tested as unqualified;
c) Manufacturers rejecting sampling for inspection and/or supervision without justifiable reasons;
d) Manufacturers who are liable for the major quality problem of certified product revealed by the media;
e) All kinds of national and provincial supervisions and random inspections on product quality are judged as unqualified and the unqualified items have a strong impact on the quality of certified products;
f) The authentication certificate is suspended or revoked due to the manufacturer's failing in meeting other requirements of compulsory product certification;
g) Manufacturers which need to be adjusted to Category D as considered by CQC as per comprehensive assessment result of the relevant quality information of manufacturers and certified products.
Note: If there is any change, classification is subject to CQC public documents.
1 Selection of Certification Mode
1.1 Basic Certification Mode
Basic certification mode: type test + post-certification supervision.
1.2 Refinement of Certification Mode
Relevant certification elements shall be added appropriately in the certification mode for different categories of enterprises according to the basic mode of certification and by combining the classification management principle of manufacturers; specific refinement is as follows:
Mode 1: Type test + post-certification supervision;
Mode 2: Type test + initial factory inspection (conformity verification) + post-certification supervision;
Mode 3: Type test (sampling) + initial factory inspection + post-certification supervision.
Relevant requirements of post-certification supervision are detailed in 5.1 Schemes of Post-certification Supervision.
1.3 Applicability of Certification Mode
Based on his own actual situation and the following Table 2, certification client may file an application for applicable certification mode.
Table 2 Applicability of Certification Mode
Category of enterprise Application type a
Initial application Category-extended application Non-extended application Certificate-based ODM application
Category A / Mode 1 Mode 1 Mode 1b
Category B Mode 2 or 3 Mode 2 or 3 Mode 1, 2 or 3c Mode 1
Category C / Mode 2 or 3 Mode 2 or 3 Mode 2 or 3
Category D / Mode 2 or 3 Mode 2 or 3 Mode 2 or 3
a: "Initial application": with no CCC certificate acquired for the product within the application scope of this Regulation, the manufacturer claims for initial certification; "category-extended application": with CCC certificate acquired for the product within the application scope of this Regulation, the manufacturer re-claims for certification for the product whose subcategory is different with that of the certified one; "non-extended application": with CCC certificate acquired for the product within the application scope of this Regulation, the manufacturer re-claims for certification for the product whose subcategory is the same as that of the certified one; "certificate-based ODM application": ODM application using the certificate obtained by the manufacturer.
b: If only the applicant or manufacturer is changed, with the product to be certified identical with the originally certified product, the manufacturer may provide information for conformity verification instead of type test.
c: If there is appreciable difference in production process between the product to be certified and the certified product, mode 2 or 3 shall be considered.
According to the characteristics of products applied for certification and the principles of certification risk control, CQC shall determine an applicable certification mode for certification client in combination with the management results of manufacturers by classification.
2 Certification Unit Division
See Article 4 of the Implementation Rule.
Products from the same manufacturer (producer) but different production enterprises (sites) shall be regarded as different application units; products from the same manufacturing enterprise (site) but different manufacturers (producers) shall be regarded as different application units.
3 Certification Procedure and Time Limit
3.1 Certification Procedure
The certification procedure includes: certification entrustment, acceptance and data review, type test and initial factory inspection, expense collection, certification result assessment and approval, issuance of certification decision and post-certification supervision, etc.
