HG/T2407-92
6.1 The product must be inspected and qualified by the quality inspection department of the manufacturer according to the items specified in this standard, and the certificate of conformity shall be issued before it can be shipped out of the factory. 6.2 Product grade determination
The product can only be determined as a product of that grade when its appearance, size and physical properties meet the requirements of the corresponding grade. 6.3 Random inspection and judgment rules
6.3.1 Batching and random inspection
6.3.1.1 The shift production or the delivery quantity is a batch, and at least 6 boxes are randomly selected from each batch of products. 6.3.1.2 At least 10 rolls are sampled from each box for appearance and dimension inspection. 6.3.1.3 At least 2 rolls are sampled from each box for physical property inspection. 6.3.2 Judgment rules
6.3.2.1 During dimension inspection, if the number of unqualified rolls exceeds 10% of the total number of sample rolls, it is allowed to take double samples from the batch of products for re-inspection of unqualified items. If more than 10% of the sample rolls are still unqualified, the batch of products is unqualified. 6.3.2.2 During appearance inspection, if the number of sample rolls that do not meet the corresponding grade exceeds 10% of the total number of sample rolls, it is allowed to take double samples from the batch of products for re-inspection of unqualified items. If more than 10% of the sample rolls are still unqualified, the batch of products is unqualified. 6.3.2.3 During the physical property test, if any item of one roll does not meet the requirements of the corresponding grade, double samples are allowed to be taken for re-test of the item. If there is still one roll that does not meet the requirements of the corresponding grade, the batch of products shall be downgraded or unqualified. 6.4 Acceptance and arbitration
The user has the right to accept the product quality according to this standard. When the user has objections to the product quality, the quality supervision agency agreed by both parties shall conduct arbitration according to this standard.
