7.1 Inspection classification
SY/T5404—2002
Product inspection is divided into factory inspection and type inspection. Product inspection is a normal temperature performance inspection of the packer, and the type inspection is a full-item inspection.
7.2 Factory inspection
7.2.1 Each batch of products must be visually inspected, and the sealing and unsealing performance tests must be carried out set by set, and the test frequency is once. 5
SY/T 5404-2002
7.2.2 Sampling:
7.2.2.1 Principle of batching and sampling method: 50 sets of products are counted as a batch per production, and less than 50 sets are counted as a batch. Two sets of products are randomly selected for inspection in each batch
7.2.2.2 Inspection content: Inspection is carried out according to the normal temperature test requirements in Table 2. 7.2.3 Judgment rules: If the product fails to meet the requirements of the standard after inspection, double inspection is carried out: If there are still indicators that do not meet the requirements, the product is judged to be unqualified. 7.3 Type inspection
7.3,1 In any of the following situations, type inspection shall be carried out: 1) When the new product is finalized;
b) When there are major changes in product structure, materials, and processes: e) When the cumulative production of products is 300:
d) When the quality control department puts forward inspection requirements 7.3.2 Batch principles and sampling methods: From the qualified products of factory inspection, every 50 sets are a batch, and those less than 50 sets are also counted as a batch. Each batch is inspected by 2 sets of random samples:
