【正文】 W or monochrome television receivers and display monitors with kinds of display types (including LCD, PDP and front/back projector)1) Products, with the same display construction, the same dimensions of CRT, the same power supply, the same critical ponents in terms of safety and EMC (Components with star * mark in Appendix III), the same electrical structure with regards to safety and EMC, may be put in the same application unit.2) Products are in the same application unit, only if power supply and the control circuit of LCD for LCD display or Plasma display are the same. 3) Products are in the same application unit, only if power supply and critical ponents of PDP are the same, maybe different in the sizes of display. And the largest size of display is required as representative model for type testing. 4) Different application unit for different power supply5) Different application unit for different construction6) Different application unit for different dimension of CRT tubes7) Different application unit for monochrome TV and color TV.GB8898GB138377Video Projector1) Products, with the same projecting mode, the same safety construction, the same power supply, the same critical ponents in terms of safety and EMC(Components with star * mark in Appendix III) and the same electrical principle with regards to safety and EMC, may be put in the same application unit.2) Different application units for different projecting modes 3) Applying respectively when power supply is different.4) Applying respectively when construction is different.GB8898GB138378CRT tubes (greater than 16cm)1)Have the same size of the diagonal demission and the same construction.。5) Description of the difference between each model/type of products in the same application unit。Vedio products of pulsory product certification 22Appendix IV Testing Requirements on factory quality control of pulsory certification of Audioamp。Vedio products………………………………………………………………………...23Appendix V Compulsory product certification requirements on factory’s quality assurance. ability…………………………………………………………………………………………..25 IMPLEMENTATION RULES FOR COMPULSORY CERTIFICATION OF ELECTRICAL AND ELECTRONIC PRODUCTSAudio amp。6) Other necessary documents . Type testing Sample delivery for type testing The principles of sample delivery for type testing For application unit containing only one model/type, sample of such model/type shall be submitted.When product series are applied for certification as one application unit, the representative samples covering Safety and EMC characteristics of the whole series shall be selected and submitted for type testing. Extra sample type should be submitted for supplementary testing when the representative samples can not cover all the requirements above.Critical safety ponents (Appendix II) in appliance should be submitted following corresponding requirements for separate testing. Separate testing can be exempted only when ponents have been CCC certificated/Voluntary certificated with admitted results as the appliance CCC regulated by CNCA, also samples and related documents are required to provide for checking. Samples quantity/amount requirementsThe applicants shall take responsibility of sample delivery for type testing in accordance with the requirements of the certification body and be responsible for them. 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..
