【正文】 different manufacturers should accept the followup surveillance respectively.The factory should assure the certified product is in normal production during the followup surveillance. The certificate holder should undertake the followup surveillance on schedule, otherwise it’ll be regarded as rejection to the followup surveillance. The frequency of followup surveillanceThe followup surveillance shall normally be implemented 12 months after the first certificate being granted with a frequency of once per 12 months.The frequency of surveillance should be increased in any of the following cases:1) If serious quality problem arises with the certified product, or the certified product is plained by clients, which has been verified to be the responsibility of the certificate holder and/or the factory.2) The certification body doubts the conformity of the certified product against the requirements of safety and EMC standards 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. Contents of followup surveillanceThe followup surveillance includes: reassessment of factory quality assurance ability + checking of consistency of certified products, and if necessary, samples may be taken and tested at the testing laboratory, refer to clause ..The certification body shall implement the factory reassessment in accordance with Requirements for Factory Quality Assurance Ability (see Appendix V). The items 3, 4, 5 and 9 specified in Requirements for Factory Quality Assurance Ability must be assessed for each followup surveillance and the rest items may be selected. All the items of the Requirements shall be covered at least every four years. The contents of consistency checking for certificated product are identical with those of the initial factory inspection basically.At the same time, the checking shall be conducted according to “Testing requirements of factory quality control of pulsory certification of Telemunication Terminal Equipment” (see Appendix IV), together with checking use of “CCC” mark and certificates. Timing of the followup surveillanceThe duration of the followup surveillance shall be determined by the amounts of units of certified products with appropriate consideration of the production scale of the factory. It will normally take about 1 to 2 working days/p. Conclusions of the followup surveillanceThe inspection team submits the conclusion of the followup inspection to the certification body. When the followup inspection conclusion is unqualified, the inspection team submits directly to the certification body. The factory should take correction action within 40 working days when nonconformity item exists. The certification body will verify the validity of the correction action with appropriate methods. The conclusions of followup inspection will be unqualified when the correction action is unpleted within the time limit. Sampling amp。 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.

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。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 accordin
