6.1 Inspection classification
The inspection classification is identification inspection and quality consistency inspection. Qualification inspection is a series of complete inspections using several samples of this model. It should be carried out when the main design, process, materials and parts are replaced or when production is resumed after suspension. Quality consistency inspection consists of four inspection groups: Group A inspection (batch-by-batch): All products are inspected when they are delivered. Group B inspection (batch-by-batch): Sampling inspection when delivering products. Group C inspection (cycle): conducted every six months. Group D inspection (cycle): Inspection is conducted during product evaluation. 6.2 Test items and sequence
The test items, test sequence and corresponding test methods and technical requirements and unqualified classification of various inspections are specified in Table 2. 387
