7 Inspection rules
7.1 Inspection classification
Product inspection is divided into type inspection and factory quality inspection: type inspection is used to evaluate the quality of all inspection items except special requirements: size inspection, wood moisture content, appearance inspection (reverse color inspection) and other structural requirements. The other inspection items are for monthly qualification. 7.2 Type inspection
7.2.1 Type inspection is carried out on products without any escape from the surface - number. Generally, type inspection should be carried out for products that are undergoing adjustment or old products that are transferred to other products under one of the following circumstances: 6) After formal production is stopped, if the structure, materials, and process have changed significantly, which may affect the product performance: ) When formal production is stopped, the accumulated plans shall be loaded regularly. After regular production, the final quality inspection shall be carried out for one year: d) After the product is discontinued for a period of time, when production is resumed: 1! 7.2.2 Sampling and product batching rules
: If the factory inspection results are very different from the previous inspection results, the same batch will be randomly selected for inspection and divided into 2 groups (including the support part). 1 will be sent for inspection: If the supply side and the supply side agree, the technical requirements will apply. 7.2.3 Inspection procedure
: 1 independent inspection shall be carried out on the corresponding parts of the product, first carry out the main size, rate, appearance inspection, and then select the mechanical properties inspection, and finally carry out the normal performance inspection. 7.2.4 Determination of the test results
The determination of the test results does not include the items required by the inspection station. The product length and deviation, large village content, old material requirements, silencer equipment requirements, physical and chemical properties, mechanical properties requirements, appearance, and structure requirements are all required. There are no ", " items in the inspection. If all the requirements are met, the number of defects does not exceed 5, it is judged as qualified, otherwise it is judged as unqualified. 7.2.5 Re-inspection
.2.5.1 During the inspection, if any party has any objection to the inspection results: or if the product has not been accepted within the specified purchase period, the party may request a friend to inspect it.
7.2.5.2 Re-inspection of the test items 7.2.5.3 Re-inspection of the items that failed the previous inspection and the items that could not be inspected due to the damage of the test piece, and put "changed inspection" in the report.
7.3 Factory inspection
.3.1 Factory inspection is the product leaving the factory or The customer inspection items that should be carried out upon delivery include product size, moisture content, appearance, color inspection, structural requirements, etc. 3.2! The whole product should be inspected. When batch inspection is carried out, the enterprise can implement sampling inspection. The enterprise should stipulate the inspection method and the specific inspection method. 3.3 [The factory inspection should be carried out by the quality inspection department of the industry and entrusted to the quality inspection agency for inspection: 7.3.4 Seven requirements: size, appearance inspection and structural requirements. Items with "H" are not marked, and all items with "H" are qualified. 7.3.5 Unqualified products shall not be considered for inspection.
8 Labeling, packaging, transportation, storage
3.1 Product identification shall comply with the product identification notes. 8.2 "Products shall be properly packaged to prevent deterioration. 8.3 Transportation
Product transportation process shall be properly managed and improved to prevent damage and layer leakage. 8.1 Storage
