12 requirements of safety 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 manufactories. The content of the check of consistency of certified product shall be the same as that during the initial inspection of the factory. Additionally, check shall also be conducted pursuant to the Testing Requirements of Factory Quality Control on Compulsory Product Certification for Switch and Control Equipment (see appendix 3). The use of CCC marks and the certificates shall also be checked The conclusion of annual inspection The inspection group shall report the conclusion of inspection to the certification body. The inspection group shall report to certification body directly in case of unfavorable conclusion of the inspection. If there is any non-conformity found in the inspection, the factory shall conduct rectification within 40 working days and the certification body shall take appropriate measures to check the results of rectification. If the rectification can not be completed in time, the factory inspection shall be concluded as unfavorable Content of the follow-up inspection The model of follow-up inspection: re-assessment of factory quality assurance ability + check of consistency of products certified, and if necessary, samples may be taken and tested at the testing laboratories (see 4.5.4). The certification body shall implement the factory re-assessment in accordance with Requirements for Factory Quality Assurance Ability. At the same time, checks shall be carried out according to the Testing Requirements of Factory Quality Control on Compulsory Product Certification for Switch and Control Equipment (see appendix 3). The items 3, 4, 5 and 9 specified in Requirements for Factory Quality Assurance Ability (see appendix 4) and the check of consistency of products must be assessed for follow-up inspection and the rest items may be selected. All the items of the Requirements shall be covered at least every four years. The duration for follow-up inspection 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 3 man-day Sampling & testing Page 10 of 46 Ref. No. CNCA-01C-011: 2007

13 If the certified products need to be sampled and tested, the samples shall be taken randomly from the qualified products of the factory (to ensure the consistency and authenticity of products to be certified, samples can be taken from market/on-site sale network, production line, stock, etc). The amount of samples taken for sampling and testing depends on the requirement of the certification body. The samples shall be sent by the factory to the testing bodies designated by the certification for testing. The sampling test, which is taken charge by the designated testing bodies, shall be completed within 40 working days. The test items specified in the standards for type testing can be applied to testing. The certification body may carry out part or all of test items based on the degree of effects on the safety performance of the products Evaluation of follow-up inspection results The certificates can be retained and the certification marks can be continuously used upon favorable annual inspection results. Actions shall be taken in accordance with Clause 5.3 of the present rule upon unfavorable inspection results. 5.
