【正文】 Have the same key assemble and producing process concerning safety performance。Have the same glass materials and suppliers。 switching power supplyPower adaptors according to functions : AC/DC, AC/AC, DC/DC, DC/AC Products with different working modes or functions shall be in different application units.2) Products, with the same electrical circuit, safety construction, and the same critical ponents in terms of safety and EMC (Components with star * mark in Appendix III), although different in model types, may be put in the same application unit.3) Products with different construction or dimension shall be in different application units. GB8898GB138376Color/Bamp。E” (as below) shall be used for certification involving both safety and EMC: Use of derivations of certification mark The products listed in this Rules shall not be allowed to use any derivations of certification mark. Ways of use Any of the following three ways is required: affixing standardsize marks (labels) printed uniformly by CNCA, printing on the nameplate or molding. Location of the markThe certification mark shall be applied on an exposed location on the outer body of the product.7. ChargeThe certification shall be charged by the certification body according to the national statutory structural fee chart.30 / 30Appendix I List of the Definition of application unit of Audio amp。 Video Products (see Appendix IV). Checking of consistency of the productThe product consistency applying for certification shall be checked on the site of production, with choice of at least one sample for each product and each manufacturer. The consistency checking includes the onsite witness testing and the following verified contents: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 constructions of products to be certified (mainly constructions in terms of safety and EMC performances) shall be identical with those of the samples for type testing.3) The dimensions of the plug of direct plugin AC adapter shall be in pliance with construction requirements of GB1002.4) The critical ponents in terms of safety (See Appendix II)and ponents having significant influences on EMC(See Appendix III) shall be identical with those declared in type testing and confirmed by certification body.The following witness test items are the least type testing requirements according to standard GB8898 for safety: Class Ⅰ equipment: Electric strength test, Grounding resistance testClass Ⅱ equipment: Electric strength testWitness testing or checking the records of verification test can be adopted for EMC characteristics. Inspection scopeAll the manufacturing premises of products applied shall be covered for inspection of factory quality assurance ability and of consistency of the products. Timing of factory inspectionNormally, the initial inspection should be carried out after the sample has passed the type testing. The type testing and factory inspection can be implemented at the same time if needed. The duration of factory inspection shall be determined by the amounts of application units of products to be certified and with consideration of the scale and distributions of factories. It will normally take about 1 to 4 working days/p for each manufacturing premises.Normally, the initial inspection should be carried out after the sample has passed the type testing. The type testing and factory inspection can be implemented at the same time in special cases. In principle, the factory inspection should be carried out within 1 year after the type testing, otherwise the type testing should be reconducted. The certificated products can be manufactured in the manufacturing premises during the initial factory inspection.The duration of factory inspection shall be determined by the amounts of application units of products to be certified and with consideration of the scale and distributions of factories. It will normally take about 1 to 4 working days/p for each manufacturing premises. Conclusions of factory inspectionThe inspection team submits conclusions of factory inspection to the certification body. The factory should take correction action within the stipulated time limit when nonconformity item exists during the factory inspection. The certification body will verify the validity of the correction action with appropriate methods. Conclusions of factory inspection will be unqualified when correction action is unpleted within the time limit. Evaluation and approval of certification results Evaluation and approval of certification results The certification body is responsible for the general evaluation of type testing results and conclusions of factory inspection. The certificate will be issued when the evaluation is qualified. The certification body will disapprove and terminate the application either the type testing result or factory inspection conclusions are unqualified Time frameTime frame for certification means the working days from the acceptance of 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, the type testing takes 30 working days, not including the time for correction actions and retest of the nonconformity item(s). If the ponents 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 ponent, 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 d
