Foreword
This document is developed based on CNCA-C12-01:2024 Implementation rules for compulsory product certification - Tyres for motor vehicles. It is issued by China Quality Certification Centre (hereinafter referred to as “CQC”), which reserves the copyright, and no organization or individual may use this document in whole or in part in any form, without the permission of CQC.
0. Introduction
The Detailed implementation rules for tyres for motor vehicles (hereinafter referred to as “this document”) is compiled according to the requirements of CNCA-C12-01:2024 Implementation rules for compulsory product certification - Tyres for motor vehicles (hereinafter referred to as “the rules”), which is used in conjunction with the implementation rules as a supporting document.
The applicable product scope and certification basis of this document are consistent with the relevant regulations of the implementation rules, and are adjusted according to the notices like catalog definition and catalog adjustment issued by the Certification and Accreditation Administration of the People's Republic of China (hereinafter referred to as the “CNCA”).
With a view to maintaining the validity of product certification, improving the product quality, serving the enterprises applying for certification, and controlling the certification risk, this document is developed and publicized according to the implementation rules and the quality manual, procedure documents, operation instructions and other relevant requirements of China Quality Certification Center (hereinafter referred to as “CQC”). By establishing the requirements for classified management of the manufacturing enterprises, combining with the classification of the manufacturing enterprises, this document specifies the implementation requirements of compulsory product certification for tyres for motor vehicles.
0.1 Definition
0.1.1 Testing at manufacturer's premises (abbreviated as TMP mode)
The testing is performed by the engineers of designated laboratory using the testing equipment of the factory laboratory and the factory shall assign testing personnel for assistance. A test report is issued after being reviewed and approved by the designated laboratories.
0.1.2 Witnessed manufacturer’s testing (abbreviated as WMT mode)
The testing is performed by factory laboratory using its own equipment, wherein the testing conditions are under the witness of the engineers of designated laboratory, or the engineers of designated laboratory witness some testing conditions and testing items according to the testing plan submitted by the factory. Factory laboratory testers are responsible for providing original records and drafting testing reports in a prescribed format together with engineers of designated laboratory. A testing report shall be issued after being reviewed and approved by the designated laboratories.
0.2 Requirements for classified management of manufacturing enterprises
CQC conducts dynamic classification management over the manufacturing enterprises based on the information it collected and sorted out related to the manufacturing enterprise and the quality of certified products. The applicants, producers and manufacturing enterprises shall cooperate with CQC.
CQC classifies the manufacturing enterprises into four categories, i.e., A, B, C and D respectively. The quality information involved in the manufacturing enterprise classification shall at least cover the following aspects:
(1) Factory inspection results, including the results of initial factory inspection and post-certification follow-up inspection;
(2) Results of sample testing and/or supervision sampling testing (including the results of type test, sampling on production site or market sampling) and sample authenticity;
(3) Results of national and provincial random inspection and CCC special random inspection;
(4) Cooperation on post-certification supervision of the applicant, the producer (manufacturer) and the manufacturing enterprise;
(5) Judicial decision, complaint arbitration, media exposure and consumer quality information feedback;
(6) Quality of certification products;
(7) Other information.
See Table 1 for the principle of manufacturing enterprise classification.
Table 1 Principle of manufacturing enterprise classification
Category Classification principle
A Category B enterprises provide conformity data to CQC, which conducts a comprehensive risk assessment on the collected quality information and the data provided by enterprises, and determines the classification results. The assessment content shall cover at least the following aspects:
(1) Within the past two years, whether any serious nonconformity related to the quality of certified products is found in the factory inspection conclusion;
(2) Within the past two years, whether any product safety performance issue is found in the product testing and/or supervision sampling testing results;
(3) Within the past two years, whether any product safety performance issue is found in the national/provincial random inspection, as well as the CCC special random inspection results;
(4) Within the past two years, whether any product safety performance issue is found in the judicial decision, complaint arbitration, media exposure and consumer quality information feedback;
(5) There is evidence showing that the enterprise is producing certified product in batches in a consistent and stable manner. If necessary, the enterprise has certain capacity for product design and testing so as to be able to analyze the quality problems of the products and take effective rectification and/or corrective preventive measures;
(6) Production conditions: having a complete production line (rubber mixing - vulcanization) (including the equipment and capacity of the producer or group company);
(7) Product testing capacity: the manufacturing enterprises (or their manufacturers, parent companies) shall have the testing capacity (excluding relative wet grip performance) required by the certification standards. The requirements for laboratory technical capacity specified in GB/T 27025 (ISO/IEC 17025) shall be met.
(8) Other information related to the quality of certification products and manufacturing enterprises.
B Manufacturing enterprises other than those of Categories A, C and D.
The manufacturing enterprises about which there is no quality information are considered as Category B enterprises in default.
C Enterprises satisfying any of the following conditions may be evaluated as Category C enterprise:
(1) The last factory inspection is determined as on-site verification due to the quality problems of the certification products;
(2) There are certain product quality problems for which the enterprise shall be responsible but which will not cause the certification certificate to be suspended or revoked;
(3) According to the results of comprehensive assessment on the quality information of manufacturing enterprises and certified products, the enterprise is adjusted to Category C enterprise.
D Enterprises satisfying any of the following conditions may be evaluated as Category D enterprise:
(1) The result of the last factory inspection is rejected due to the quality of the certified products;
(2) The supervision sampling testing results are rejected, which affect the product safety performance;
(3) Inspection and/or supervision sampling is refused without justified reasons;
(4) There are severe defects in product quality for which the enterprise shall be responsible, which may result in certificate suspension or revocation;
(5) The results of the quality supervision and sampling at the national level and provincial level as well as the CCC special inspection for various products are rejected, which affect the product safety performance;
(6) According to the results of comprehensive assessment on the quality information of manufacturing enterprises and certified products, the enterprise is adjusted to Category D enterprise.
CQC will determine the classification results (categories) of manufacturing enterprises according to the above classification principles based on all kinds of quality information collected in real time.
CQC shall periodically or irregularly reclassify and grade manufacturing enterprises based on various information, in order to enable dynamic management. In case of any change, the documents disclosed by CQC shall prevail. In principle, the degradation of enterprise categories shall be adjusted according to the classification principles of manufacturing enterprises specified in Table 1, and the promotion of enterprise categories shall be promoted step by step according to the order of D-C-B-A. If necessary, the category can be directly adjusted to the corresponding one after risk assessment.
