For any unqualified index in the test results, double sampling shall be taken from the original inspection batch number, and the unqualified items shall be re-inspected. If all the re-inspection results are qualified, the batch of products shall be judged to be qualified. If one item or one index is still unqualified in the re-inspection, the product shall be judged to be unqualified. 6.4 Quality Assurance
For products that have been qualified by the supplier and accepted by the purchaser, the purchaser may re-inspect any item according to this standard. If any qualified item is detected in the re-inspection, the batch products containing unqualified items shall be returned or exchanged after confirmation by the supplier. In case of quality disputes, the national quality supervision unit shall conduct arbitration according to the provisions of this standard. 7 Marking, packaging, transportation, purchase and storage
