【正文】 The sample quantities of appliances shall be according to the requirements of Table below, the quantities for safety ponents acpanying the appliances tested separately shall be according to the requirements of Appendix II Sample quantities of the type testingAppliance（Representative type）2 setsSample quantities of the type testingAppliance（derived type）1 set Handle of samples and relating documents The samples tested and/or the relating documents should be dealt with in appropriate ways after type testing. Test standards, items and methods Test standards: 8898:Safety Requirements of household and similar use apparatus powered by mains supply. 13837: Limits and Methods of Measurement of Radio Interference Characteristics of Sound and Television Broadcast Receivers and Related Apparatus.3. The Limits For the Harmonic Current Emissions Caused by Lowvoltage Electronic Equipments (Equipment Input Current ≤16A per Phase)Note: Latest Version of standards mentioned above should be automatically implemented. Explanation will be made by CNCA in special cases. Test items The test items for safety shall include all appropriate items specified in standard GB8898. The test items for EMC shall include all appropriate items specified in standards GB13837 and ... Test methods The type testing shall be carried out according to regulations of relative product standards and corresponding methods and/or standards cited.. Type testing report and product description reportTesting body issues the Type testing report when the type testing pleted.When type testing items are partially unqualified, applicant is allowed to make correction。 the correction should be acplished within the time limit stipulated by certification body (count from the date of unqualified notification). The application will be regarded as abandoned if the correction is not acplished within the time limit. Also the applicant can choose to terminate the application.Product description report is the file including the relative information for all the model types of the application. The certification body piles and issues the Product description report template according to regulated contents and format. Contents of the report should be clear and integrated.The certification body should provide the Type testing report and Product description report to the applicant in time. The certification holder should assure the valid and integrated reports can be acquired in the factory. Initial inspection of the factory Contents of the inspection The contents of factory inspection shall include the assessment of factory quality assurance ability and product consistency checking. Assessment of factory quality assurance ability. The inspector assigned by the certification body shall carry out the factory quality assurance ability assessment according to the Requirements for Factory Quality Assurance Ability (see Appendix V) and supplementary assessment requirements regulated by CNCA. In the meantime, the inspector shall carry out checking according to Testing Requirements of Factory Quality Control of Compulsory Certification of Audioamp。 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 manu
