Inspection classification
Table 4 Sampling and judgment plan for specification and appearance inspection Product inspection is divided into factory inspection and type test inspection, and the samples are collected and sent out! The inspection items are all items in the requirements except for the sanitary indicators. Acceptance number A
Type inspection items are all items in the requirements. Type inspection should be carried out in any of the following situations: trial production and identification of new products or test products for transfer to factory production; after formal production, if the structure, materials, and process have significant changes, , which may affect the product performance; during normal production, it is conducted once a year; when the product has been suspended for a long time, the production is resumed; when the inspection results are significantly different from the "type inspection"; when the national quality supervision agency proposes a request for type inspection. 7.3 Determination of inspection results
The unit is the rejection number R
The size difference and appearance of the sheet material. If any item is unqualified: the roll of product is judged to be unqualified. The qualified batch is determined according to Table 4. 7.3.2. The physical properties of the sheet material should all meet the requirements of the standard stall; if there are unqualified items, the original batch of products should be Randomly draw double samples from the products and retest the unqualified items. If the retest still fails, the batch of products shall be judged as unqualified. 7.3.3
If any of the health indicators fail to meet the standards, the batch of products shall be unqualified. 7.3.4
If the products meet the standards according to 7.3.1, 7.3.2 and 7.3.3, the batch of products shall be judged as qualified products. 8 Marking, packaging, transportation and storage
8.1 Marking

The sheet roll or the packaging shall be accompanied by a certificate of conformity. Indicate the production order on the certificate of conformity or the instruction manual. Location, address, product name, specification, weight or length, coating surface, batch number, production date. There are packaging box dimensions (length × width × height) and signs such as anti-condensation, heat protection, and oil protection.
8.2 Packaging
8.2.1 Carton packaging: The chain roll sheet is packed with plastic film as the inner packaging, and the supporting grade box is used as the outer packaging, and the packaging tape is used to seal the hole: 8.2.2 Pallet packaging: Each roll of sheet is packed with a whole material film as the inner packaging, placed upright or lying on the pallet, protected by tile board cardboard above and below, and fixed with packaging bundles.
8.2.3 Special packaging is agreed upon by the supply and demand parties. 8.3 TransportationwwW.bzxz.Net
