7 Rules
QB/T 2480—2000
.1 Products can only leave the factory after being inspected and qualified by the quality inspection department of the manufacturer and accompanied by a certificate of conformity. . . 2 Inspection classification
Inspection is divided into two categories: inspection and type inspection: T. 2. 1 Factory inspection
Mountain! The inspection items are the external measurement, specification size, curvature, longitudinal shrinkage and chain drop impact test of the pipe. Method B: The external measurement, specification size and baking test of the pipe. 7.2.2 Single type inspection
During normal production, the inspection is carried out once a year: weather resistance test is carried out once every three years. When there are special requirements, the type inspection of this standard should also be carried out. 1) When the new product is tested and identified
b) After formal production, the structure, raw materials and process will have minor changes, which may affect the performance of the product: 2) When the product is stopped for more than two months, when the production is resumed, the inspection results are different from the last type inspection: 3) When the quality supervision regulations require the type control inspection. 1.3 Batching and sampling
7.3.1 Batching
A batch of products produced in reverse with the same raw material formula, process, variety and specification. The quantity of each batch of pipes shall not exceed 1, and the number of pipe fittings shall not exceed 5,000. The minimum batch size can be a batch of products with a production period of 10 days.
7.3.2 Bundle sampling
7.3. 2. 1 Strict inspection
The inspection of package size, specifications and tolerances shall be carried out in accordance with the regulations of GB/T2828, with a normal sampling plan: take 1 section for inspection, and the qualified standard is AQL6.5, see Table 7. 12 sections are taken for inspection, and the number of samples is (pieces). The sampling plan and judgment range of batch are shown. 151--280 281500 5011200 120 [--3209 3201~1IO 7. 3. 2. 2 Type inspection Sample is too small\
Qualified products are listed as A. In the output! Sufficient products are randomly selected from the qualified products for type inspection: 4 judgment rules and multiple inspection rules are given. (pieces) The judgment is invalid. Appearance, size and curvature are judged according to the provisions of 7. When one item of physical performance fails to meet the specified standard, a double sample can be randomly selected from the sample household for re-inspection. If there is any unqualified, the batch is judged as unqualified.
