Inspection rules
7.1 Inspection classification
Inspection is divided into type inspection and quality consistency inspection. Type inspection should be carried out when the main design, process, materials and main parts are replaced, or when production is resumed after suspension. Quality consistency inspection is carried out in three situations: Group A inspection (batch by batch): full inspection when the product is delivered; Group B inspection (batch by batch): sampling inspection when the product is delivered; Group C inspection (periodic): once every two years. The test samples are randomly selected from the qualified batches. Test items and non-conforming classification
The test items, test methods, technical requirements and non-conforming classification of various types of inspections are shown in Table 4. Table 4 Test items, test methods, technical requirements and classification of non-conforming items No.
