Editorial scope guide. The points are also available as readable text below.
A test or inspection result is useful only when it can be linked to the material, part and configuration being supplied. A report with impressive values but no identifiable scope is difficult to use for acceptance.
Check the identifiers first
Match the drawing revision, part number and batch or sample reference across the purchase order and inspection report. Where a material certificate is included, check how it is linked to the manufacturing batch. Keep unrelated test reports out of the acceptance package.
Record deviations instead of hiding them
If a measurement, material or process differs from the agreed requirement, describe the difference and its approval status. A supplier should not silently replace a missing result with an unrelated generic certificate. The customer’s acceptance authority should be clear before shipment.
Example scenario
A report shows a passing result for an earlier sample, but the current order uses a revised drawing. Ask the supplier to identify which results remain applicable and what has been reviewed again. Keep the earlier report with its original sample reference.
Points to record
| Identity chain | Connect order, drawing, batch and sample references. |
|---|---|
| Result scope | State what was tested and in which condition. |
| Deviation record | List departures and the approval decision. |
