Note 1."New design life" depends on the use of the product, market demand, effectiveness, economic factors, technical level, etc. Note 2.Rewrite IEC 62309 and define 3.6. 3.4 As-new designed life (ANDL) The life expectancy of products containing reused parts under specific operating conditions. Note 1.The new design life and the new design life do not need to be exactly the same or have a fixed proportional relationship, but the new design life should not be shorter than the new design life. Note 2.Rewrite IEC 62309 and define 3.7. 3.5 Remaining working life The time interval from a specified point in time for the component to the limit state of the component. Note. Rewrite IEC 62309, definition 3.8. 3.6 Reuse Parts that have been used in a product are used directly after being disassembled or used for the original purpose after being cleaned and repaired behavior. 3.7 Recycling The act of recycling materials that have been used to constitute a product, after being disassembled and processed, to continue to be used for the original purpose.

4 Inspection supervision

4.1 General requirements Imported products containing reused parts and components shall comply with relevant national laws and regulations and the requirements of safety, sanitation and environmental protection standards. 4.2 Inspection and supervision methods The inspection and supervision of imported products containing reused parts adopts product inspection (4.3) or conformity verification (4.4), or a combination of methods. 4.3 Product inspection 4.3.1 Sampling Random sampling should be conducted in accordance with the sampling rules for brand-new products of the same kind. If the selected sample size is larger than the batch size, the entire inspection lot shall be carried out. Number inspection. 4.3.2 Inspection content 4.3.2.1 Logo and instructions The labeling of products containing reused parts shall comply with relevant national laws, regulations and standards, and shall be The remanufacturing mark shall be marked on the obvious position of the product packaging (if applicable), and the mark shall meet the requirements of GB/T 27611. 4.3.2.2 Performance, safety, hygiene and environmental protection requirements The performance, safety, hygiene and environmental protection requirements of products containing reused parts shall be the same as those of products composed of new parts. Its sampling party The type and inspection items shall follow the inspection procedures of the corresponding products. 4.4 Compliance verification The inspection documents and vouchers, and the goods should be consistent, and comply with the mandatory requirements of the relevant national technical specifications. If necessary, refer to Appendix A, B, C conduct verification and implement verification.

5 Disqualification and disposal

5.1 If all relevant contents of the inspection, supervision and conformity verification of products containing reused parts are qualified, the batch of products shall be judged as qualified. It is unqualified. 5.2 If the personal property safety, health, and environmental protection items are unqualified, the party concerned shall be ordered to destroy it, or a notice of handling the return of the goods shall be issued Only go through the return procedures; if other items are unqualified, technical processing can be carried out, and only after re-inspection can be sold or used. A.2 Functional characteristics and quality A.2.1 Unless otherwise stated, products containing reused parts shall meet the same technical standards and requirements as products composed of new parts. Have the same function. A.2.2 Compared with the new parts, the reused parts are allowed to have slight specification differences. These deviations depend on the product, but these Changes should be clearly specified in the product identification process documentation. A.2.3 The reused parts and components shall pass the same or equivalent inspection and functional test as the brand-new parts during the product manufacturing process. A.2.4 Reused parts products should pass the same inspection and functional tests as products composed of new parts. A.3 Environmental issues A.3.1 When reused parts are used in production, it should be considered and ensured that the environmental pollution caused by the use of reused parts will not be more Many parts are produced. For example. energy consumption, recycling of hazardous substances and materials. A.3.2 Reused parts can be used as spare parts, thereby improving the long-term utilization rate of the product. A.3.3 Consider how the product will be disassembled at the end of its life to reduce the cost of restoring parts. The more complex the design, the zero is restored The more difficult and expensive the parts are. If the dismantling is less than a certain cost, the number of reused parts will increase. Note 1.Attention should be paid to products that contain harmful substances, and whether these substances are intended to be recycled. Note 2.Relatively high energy consumption should be considered undesirable unless the production of new products is expensive or difficult. A.3.4 Consideration should be given to the disposal of waste oil and scrap parts generated in the process of dismantling and restoring parts, and the corresponding water circulation and air circulation Evaluate whether the treatment is reasonable and effective. A.4 Security Products containing reused parts and components shall fulfill current safety and quality assurance requirements to comply with current sales conditions and regulations. A.5 Remaining service life The remaining service life of reused parts should be able to meet the new design life of the final product. A.6 Traceability In order to ensure traceability, it is recommended to use production records to prevent the remaining service life of parts from being lower than the product’s new design life Life. For low-cost parts, labels or identification marks can be used to distinguish and reuse.

Appendix B

(Informative appendix) Qualification test of products containing reused parts B.1 Assessment of current status Procedures should be established to evaluate the status of products containing reused parts. Evaluation methods can include manufacturer’s data sheets or parts Life testing, and the proper use of the quality management system can support the production control and evaluation process. These procedures can be. --Appearance inspection, measurement and product function test applied to new parts and components; - To assist in confirming whether the parts can be reused, evaluate the designed running time counter, loss counter, etc., and give Display the remaining working life information (for example. wear characteristic curve, Weibull chart); --Check whether the appearance of reused parts remains intact; - If the mechanical structure is to bear the load, it should also include appropriate monitoring or testing, such as X-ray or ultrasonic testing Try and wait -Evaluation of software status. B.2 Reliability assessment Through analysis and/or testing, it is verified that the failure intensity and failure rate of products containing reused parts are not higher than those of products composed of new parts. The product is not less than the new design life of the product category, and the reliability stress screening can be ignored for reused parts. The purpose of analysis and testing is to confirm Guaranteed reused parts products can reach the same level of performance and reliability as the new design life of the product category. B.3 Final inspection and test The final inspection and test of the functional test of the product containing the reused parts shall be the same as that of the product composed of new parts.

Appendix C

(Informative appendix) Supplementary instructions for applying reused parts C.1 Reliability of reused parts In the manufacturing process, reused parts should have at least the same function as new parts, and the expected service life of reused parts Should at least match the design life of the product composed of new parts. Therefore, the remaining service life of reused parts can be guaranteed not to be reduced Low product class new design life. These can be verified by the following methods. analysis of the failure distribution of new parts and the distribution of reused parts Relevant information such as remaining service life, or sampling of designated reused parts, testing helps to estimate the time of failure distribution. For satisfaction Comply with the test/analysis of single parts production (non-mass production or multi-part production), similar parts can be used when necessary Historical data. The characteristic curve shown in Figure C.1 describes the parts due to wear...
