0 Introduction
The Rules is prepared based on safety risks and certification risks of horn products for motor vehicles and specifies the basic principles and requirements for implementing compulsory product certification on horns for motor vehicles.
The Rules shall be used together with the general implementation rules issued by the Certification and Accreditation Administration of the Republic of China (CNCA), e.g., Rules for the Implementation of Compulsory Product Certification - Manufacturing Enterprise Classification Management, Certification Mode Selection and Determination, Rules for the Implementation of Compulsory Product Certification - Utilization of Testing Resources and Other Certification Results of Manufacturing Enterprises and Rules for the Implementation of Compulsory Product Certification - General Requirements for Factory Inspection.
The certification authority shall formulate the detailed rules for the implementation of certification in accordance with the requirements of general implementation rules and the Rules, and shall implement these detailed rules together with the general implementation rules and the Rules.
Manufacturing enterprises shall ensure that the certified products they manufacture continuously meet the requirements of certification and applicable standards.
1 Application Scope
The Rules is applicable to the horn products for Categories M, N, L3, L4 and L5 electrically driven or compressed air-driven motor vehicles.
The adjustment of application scope caused by the changes of laws, regulations, relevant product standards, technologies, industrial policies and other factors shall be subject to the announcement issued by CNCA.
2 Certification Standards
GB 15742 Performance Requirements and Test Methods of Horn for Motor Vehicles
In principle, the latest edition of above standard issued by the administrative department of national standardization shall apply. Other editions of the standard, if required, shall be subject to the CNCA's announcement on applicability to the requirements of relevant standards.
3 Certification Mode
Basic certification mode for compulsory certification of horn products for motor vehicles is as follows:
Type test + initial factory inspection + post-certification supervision;
The post-certification supervision in the above-mentioned basic certification mode refers to one among the three kinds of modes: post-certification follow-up inspection, sampling testing or inspection on production site, and market sampling testing or inspection.
The certification authority shall carry out classified management over the manufacturing enterprises according to the requirements of Rules for the Implementation of Compulsory Product Certification - Manufacturing Enterprise Classification Management, Certification Mode Selection and Determination and also appropriately add the combination of various post-certification supervision modes on the basis of basic certification mode in combination with the classified management results, in order to determine the certification mode applicable to the certification client.
4 Certification Unit Division
In principle, the horn products for motor vehicles produced by the same producer (manufacturer) in the same manufacturing enterprise (site) and free of significant difference in the following aspects shall be regarded as a certification unit:
(1) Operating principle and category;
(2) Shape of assembly and quantity of acoustic transmit units;
(3) Shape and dimension of diaphragm;
(4) Shape or type of sound outlet;
(5) Rated sound frequency;
(6) Rated voltage/rated air pressure.
In principle, the certification client shall propose certification entrustment according to unit division principle. One unit may contain multiple "models (or specifications)" of products. Products of the same model refer to the products having no effect on compliance with standards in design.
For the same products with the same producer but different manufacturing enterprises or the products of the same model with different producers but the same manufacturing enterprise, type test may only be conducted on the samples within one unit; and for the products of other manufacturing enterprises/producers, necessary data shall be provided for conformity check.
