3.2 Basis for inspection and acceptance
The basis for inspection and acceptance includes:
GB/T33990—2017
a) Extracts of relevant data production contracts and task books on product quality characteristics or entrusted inspection and acceptance documents: b) Technical requirements (including technical standards, technical design documents and relevant technical regulations). 3.3 Two-level inspection and one-level acceptance system
3.3.1 The results of the lunar digital map products should pass the process inspection of the production party's operating department, the final inspection of the production party's quality supervision department and the acceptance of the production entrusting party in turn. Figure 1 is the quality inspection and acceptance flow chart of the lunar digital map. 3.3.2 If the information is incomplete or the data is incomplete, the department responsible for inspection or acceptance has the right to refuse inspection and acceptance.

Units that fail the inspection
Results shall be returned for modification
4.1.3 Errors in the process inspection shall be modified and reviewed until all unit results are inspected and found to be correct, and then they can be submitted for final inspection.

4.2.2 The final inspection shall be carried out in detail for all unit results. 4.2.3 Problems found in the final inspection shall be recorded in the inspection record. 4.2.4 The process inspection record shall be submitted for the final inspection. 4.2.5 Unit results with errors in the final inspection shall be returned for modification, and the final inspection shall be carried out after the process inspection is correct until the inspection is correct. 4.2.6
All unit results can be submitted for acceptance after the final inspection is correct. 4.2.7
After the final inspection is completed, an inspection report should be written. After the final inspection is completed, a written application for acceptance should be made. 4.2.8
4.3 Acceptance
Unit results can be accepted after all have passed the final inspection. Acceptance adopts sampling inspection.
Unit results selected as samples in the acceptance shall be checked in detail one by one, and unit results outside the sample shall be checked as needed. Problems, errors and results of the acceptance inspection shall be recorded in the inspection record. The final inspection record shall be reviewed during the acceptance.
Unit results that fail the acceptance shall be returned for processing and resubmitted for acceptance. When re-accepting, re-sampling shall be carried out. Unit results that pass the acceptance shall be corrected for errors found in the inspection and verified through re-inspection. After the acceptance is completed, an acceptance report should be prepared. The format of the lunar mathematical map quality inspection and acceptance report can be found in Appendix A and Appendix B. The acceptance work procedures are as follows:
Determine the sample size. The sample size is drawn according to 15% of the number of unit results. When the number of unit results is less than or equal to 20, at least 3 samples should be drawn.
Draw samples. According to the sample size specified in 4.3.9a), use simple random sampling to draw samples. b)
Inspect. Conduct a detailed inspection of the samples, and conduct a general inspection of the products outside the samples as needed. d) Unit result quality assessment. Conduct a unit product quality assessment in accordance with the provisions of 6.2. Quality assessment of all product results. Conduct a quality assessment of all product results in accordance with the provisions of 6.3. e
Prepare an acceptance report. After the acceptance is completed, refer to the contents of Appendix A to prepare an acceptance report. f)
