Scope This document applies to cartridge fuse-links of miniature fuses for the protection of electric appliances, electronic equipment and component parts thereof normally intended to be used indoors. 2. Certification model Type testing + Initial inspection of the factory + Follow - up inspection 3. Major processes of certification 1 Application for certification 2 Type testing 3 Initial inspection of the factory 4 Evaluation of certification results and approval of certification 5 Follow up inspection 4. General requirements for certification 1 Application for certification 4.1.1 Defining of the unit of application for certification In principle, application units shall be defined according to the standard sheet of the miniature fuses. The product of same model/type and same manufacturer but with different factories shall be defined into different application unit. 4.1.2 Application documents The formal application shall be submitted with the following documents: 1) Product assembly chart , etc. 2) List of critical components and/or materials 3) Description of the difference between the different model/type of products in the same application unit 4) Other necessary documents 4.2 Type testing 4.2.1 Samples delivery for type testing 4.2.1.1 The principles of sample delivery for type testing In one application unit, one specification of every three should be selected for full item tests according to the standards, and the other two specifications should be tested for all the items except breaking capacity and endurance tests. 4.2.1.2 Samples quantity/amount requirements The applicants shall take responsibility of sample delivery for type testing in accordance with the requirements of the certification body and be responsible for them. Quantities of samples required: Cartridge fuse-links: 48 pieces for each specification of one application unit; 4.2.1.3 Handle of samples and relating documents after type testing The samples tested and/or the relating documents should be handled in appropriate ways after type testing. 4.2.2 Test standards, items and methods for type testing 4.2.2.1 Test standards (1) GB9364.1-1997 “Miniature fuses Part 1: definitions for miniature fuses and general requirements for fuse-links” (2) GB9364.2-1997 “Miniature fuses Part 2: Cartridge fuse-links” (3) GB9364.3-1997 “Miniature fuses Part 3: Sub-miniature fuses” 4.2.2.2 Test items The type testing shall be carried out according to total items and methods specified in the standards. 4.2.2.3.Test methods The type testing shall be carried out according to the methods specified and / or referred the standards. 3 Initial inspection of the factory 4.3.1 Contents of the inspection The contents of factory inspection shall include the factory quality assurance ability assessment and the products consistency check. 4.3.1.1 Assessment of factory quality assurance ability The inspector assigned by the certification body shall carry out the factory quality assurance capability inspection according the Requirements for Factory Quality Assurance Ability (see appendix 2) and the additional inspection requirements stipulated by CNCA. The inspection shall cover the requirements of Testing Requirements Factory Quality Control of Miniature Fuses (see appendix 1). 4.3.1.2 Check of consistency of the product The consistency of the product applying for certification shall be checked on the site of production. If more than one application unit are involved in the certification, at least one type/model sample shall be taken from each unit for the product consistency check. The following major points shall be checked: 1) The name of product, type/model and specification on the nameplates and packages of products to be certified shall be identical with those indicated in the type testing reports. 2) The construction of products to be certified shall be identical to those of the samples for type testing. 3) The critical components and materials shall be identical with those declared in type testing and confirmed by certification body. The witness tests on site, if necessary, should be carried out to confirm safety of the products during the factory inspection. 4.3.1.3 Inspection scope All the products to be certified and processing premises shall be covered for inspection of factory quality assurance ability and of consistency of the products. 4.3.2 Timing of factory inspection Normally, the initial inspection should be implemented after the sample has passed the type testing. The type testing and factory inspection can be implemented at the same time in special cases. The duration of factory inspection shall be determined by the amounts of application units of products to be certified and with the consideration of the scale of the factory. It will normally take about 1 to 4 man-day for each processing premises. 4.4 Evaluation of certification results and approval of certification 4.4.1 Evaluation of certification results and approval of certification The certification body shall be responsible for a general evaluation of the results of type testing and factory inspection and for issuing the certificates to the applicants for the conformed products. One certificate shall be issued for one application unit. The application of the certificates shall comply with the requirements for Regulations for Compulsory Product Certification. 4.4.2 Time frame Time frame for certification means the working days from the acceptance of complete application till the issuance of the certificates, which includes the time of type testing, factory inspection, reports submission after inspection, evaluation of certification results and approval of certificates, etc. Normally, type testing takes 30 working days, not including the time for corrective actions and retest of the non-conformity item(s). If the components are required to be tested and the required time exceeds that of appliances, the time of type testing should be calculated according to the longest test time of the component, counting upon the receipt of the samples and testing fees. The inspection reports should be submitted within 5 working days after the inspection. It will be counted from the day when the inspectors complete the inspection and receive from the factory the corrective action reports on non-conformities satisfying the requirements. Evaluating certification results and approving the certificates shall normally be completed within 5 working days. 4.5 Follow - up inspection 4.5.1 The frequency of inspection The follow-up inspection shall normally be implemented at least once per year. The first follow-up inspection shall normally be implemented 12 months after the certificate being granted. The frequency of inspection should be increased in any of the following cases: 1) The certified product has serious quality problem, or is complained by clients, which has been verified to be the responsibility of the certificate holder. 2) The certification body doubts the conformity of the certified product against the requirements of safety with sufficient reasons. 3) Sufficient information indicates that the conformity or the consistency of certified products might be affected due to the changes in organization structure, production condition and the quality system of the manufacturer and/or factories. 2 Contents of the follow – up inspection The model of follow-up inspection: re-assessment of factory quality assurance ability + check of consistency of products certified, and if necessary, samples may be taken and tested at the testing laboratories, see 4.5.3. The certification body shall implement the re-inspection of factories in accordance with the Requirements for Factory Quality Assurance Capability (see appendix 2). The items 3, 4, 5 and 9 specified in Requirements for Factory Quality Assurance Capability must be assessed for follow-up inspection and the rest items may be selected. All the items of the Requirements shall be covered at least every four years. In addition, the inspection shall cover the requirements of Testing Requirements Factory Quality Control of miniature fuses(see appendix 1). The duration for follow-up inspection shall be determined by the amounts of units of certified products w...
