A useful QC record identifies the order and unit, states the acceptance criteria, records actual results and shows who authorized release.
| Control area | Typical checks | Evidence |
|---|---|---|
| Identity | Order, model, revision, unit or batch identity. | Traceable checklist and labels. |
| Dimensions and materials | Critical dimensions, approved material and finish. | Measurement and matched records. |
| Assembly and function | Doors, covers, lighting and selected installed functions. | Recorded result; photo/video where useful. |
| Appearance | Finish, alignment, scratches, dents and cleanliness. | Inspection record and defect disposition. |
| Packing | Accessories, protection, fixing, moisture control and marks. | Packing checklist and photographs. |
| Documents | Required material, test, certificate and warranty files. | Compliance Dossier index. |
HOLD rule: a failed or missing contract requirement is not closed by deleting the checklist item. The unit remains on HOLD until corrective action and reinspection are recorded.
