【正文】 dy will inspect the factory according to the requirements of initial factory inspection and conduct the type testing to the sample of each certificate units. When the factory inspection and type testing results are qualified, the suspended certificate will be resumed.When the results of the followup sampling and testing are unqualified, the certification body will suspend or withdraw the certificate according to the degree of the disqualification. When the certificate is suspended, the holder should apply for the certificate resuming and accept the factory inspection in a period of 2 months after 1 month of the suspending date, otherwise the certificate will be withdrawn by the certification body. The certificate will be resumed only if the result of factory inspection is qualified. If the result is unqualified, the certificate will be withdrawn.The certification body should proclaim the suspended, cancelled and withdrawn certificate in proper ways.6. Use of pulsory product certification markThe certificate holder shall follow the Regulations for Compulsory Product Certification Mark Design of the authorized mark The certification mark with letter reference “S” (as below) shall be used for certification involving safety only:The certification mark with letter reference “Samp。 Video products for pulsory certificationNo.ProductsPrinciples of the definition of application unitStandards1Powered sound boxes with single or multiple speakers1) The application samples, 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), but different only in output power, may be put in the same application unit.2)According with requirement of item 1), Powered sound boxes with single or multiple speakers have different amount passive boxes could be in one application unit.3)According with requirement of item 1), Powered sound boxes with single or multiple speakers have different input power could be in one application unit.
