TTTKAONKAca-
SJ 20577- 96
When all inspection items meet the requirements of Chapter 3 and Chapter 5, the identification inspection is considered qualified. If any inspection item does not meet the specified requirements, the inspection should be suspended. The contractor should analyze the unqualified items, find out the causes of the defects and take corrective measures, and then continue to conduct retrospective inspections on the unqualified items and related items. If all inspection items meet the specified requirements, the identification inspection is still considered qualified; if there is still an item that does not meet the requirements after continued inspection, it is considered unqualified.
4.4.4: Maintaining the qualification for identification inspection
In order to maintain the qualification for identification inspection, the contractor should provide product test data or qualified certification data according to the requirements of the ordering party or the superior identification agency, generally submitting them once a year. 4.5 Quality consistency inspection
4.5.1 Inspection grouping
Quality-related inspections are divided into four groups: A, B, C, and D. 4.5.2 Formation of inspection lot
The formation of inspection lot shall comply with the provisions of Article 3.6 of JB179: 4.5.3 Group A inspection
Group A inspection mainly inspects the characteristics that are easily affected by changes in production process or production skills and the performance that is crucial to meet the predetermined requirements (i.e., inspection of main performance). 4.5.3.1 Inspection items
The inspection items of Group A are shown in Table 1:
4.5.3.2 Full inspection
100% of the inspection lot products submitted by the contractor shall be inspected by Group A. The quality level (acceptable quality level) of the inspection lot is expressed by the number of defects per 100 units of product. According to the receiver's use requirements and with reference to historical data, the ordering party and the contractor shall negotiate and stipulate. If there are no other regulations, the following values ​​are recommended: serious defects: 6.5, 10, 15, 25; minor defects: 15, 25, 40, 65. The calculation method for the number of defects per unit product is as follows: total number of defects = number of unit product defects × total number of inspected single-diameter products * 100. See Appendix A (reference) for defect classification. 4.5.3.3 Qualified criterion The whole batch determination method of the inspection of the station (department) is adopted. According to the inspection results, if the number of defects found is not greater than the specified value, the batch of Group A is judged to be qualified; otherwise, the batch of Group A is judged to be unqualified.
Fateful defects are not allowed in Group A inspection. If fatal defects are found, the batch shall be rejected. 4.5.3.4 Re-inspection
For batches that do not meet the Group A inspection requirements, the contractor shall analyze the batch of receivers, find out the cause of the defects and take corrective measures. The batch may be resubmitted for inspection. The resubmitted batch shall be separated from the new batch and marked with "resubmitted batch". If the re-inspection is qualified, the batch is still judged to have met the Group A inspection requirements; if the re-inspection is still unqualified, the batch is judged to have failed the Group A inspection.
4.5.3.5 Sample processing
For batches that meet the Group A inspection requirements, the contractor shall be responsible for repairing the defective products. When the requirements specified in the product specifications are met, the batch may be delivered in batches according to the contract or order. 4.5.4 Group B inspection
SJ 2057796
Group B inspection mainly checks the characteristics that are more affected by the quality of parts or receivers, and less affected by the production process or production skills, as well as those that require special tooling or special environment (that is, the inspection of general performance and special performance). Group B inspection should be carried out on the receivers of the qualified batch of Group A inspection. 4.5.4.1 Inspection items
Group B inspection items are shown in Table 1. According to the specific situation of the product, Group B inspection can be merged into Group A inspection. 4.5.4.2 Sampling plan
4.5.4.2.1 Continuous batch
The continuous batch Group B sampling inspection adopts the - sampling plan of general inspection level II in GJB179. The acceptable quality level (AQL) value is recommended from Table 2 Select from.
Table 2 Acceptable quality level (AQI.)
Defect category
Serious defect
Minor defect
4.5.4.2.2 Single batch
The single batch or only a few batches (such as the first batches after the important design, process, and main raw materials are changed before the design is finalized or the production is finalized) shall adopt the one-time sampling plan of the general inspection level ⅡI in GJB179. The limit quality (IQ) value and the corresponding acceptable quality level (AQL) value shall be selected from Table 3. Table 3 Limit quality (LQ)
Defect category
Serious defect
Minor defect
Defect classification see Appendix A (reference)
4.5.4.3 Qualification Criteria
Pa= 100%
According to the inspection results, if the number of defects found is less than the number of defects determined, the batch is judged to have passed the Group B inspection; otherwise, the batch is judged to have failed the Group B inspection.
4.5.4.4 New Vehicle Inspection
For batches that have failed the Group B inspection, the manufacturer shall analyze the batch of products, find out the causes of the defects and take corrective measures before resubmitting them for inspection. During re-inspection, the re-submitted batch shall be separated from the new batch and marked with "re-submitted batch", and strict inspection shall be adopted.
If the re-inspection is qualified, the batch is still judged to be qualified for the Group B inspection; if the re-inspection is unqualified, the batch is judged to be unqualified for the Group B inspection
4.5.4.5 Sample processing
For the batches that have passed the Group B inspection, the manufacturer shall be responsible for repairing the defective products, and after meeting the requirements of the product specifications, they can be delivered in batches according to the contract or order. 4.5.5 Group C inspection
