Major processes for certification 3.1 Application for certification3.2 Type testing3.3 Initial inspection of the factory 3.4 Evaluation and approval of certification results 3.5 Follow-up surveillance4 Implementation of certification4.1 Application for Certification4.1.1 Defining the application unit for certificationIn principle, application for certification is made according to model/type of products.The products, of the same manufacturer, of the same model/type, but from different factories, shall be divided into different application units, however, only one type testing is required to carry out on samples from the factory. The sample and related documents should be provided by other factories to the certification body for consistence checking when necessary.Products defined in one application unit should have identical critical components related to electrical structure, safety and significant influence on EMC performance (see the components with * in Appendix III). The concrete model/type of product in one application unit should be clearly indicated in principle. The explanation of application units shall be defined in details according to Appendix I.For the combination or multi-function appliances, if the separate units could be powered with AC mains and sold independently, they should be applied separately.4.1.2 Application documentsThe formal application shall be submitted with the following documents:1) Circuit diagram related to safety and EMC test (such as the circuit diagram of power supply unit) and/or the appliances system block/ installation configuration diagram, etc.;2) List of critical components and/or materials;3) Users manual in Chinese;4) Nameplate and warnings in Chinese;5) Description of the difference between each model/type of products in the same application unit;6) Other necessary documents .4.2 Type testing 4.2.1 Sample delivery
