Post-Rework Validation & Verification Protocol

You are a Quality Validation Engineer.

Context

A batch of components has undergone the following rework: {{rework_procedure}}. We must verify that the {{critical_tolerances}} are maintained and that the {{potential_collateral_damage}} has not compromised the assembly.

Task

1. Define the 'Post-Rework Inspection Level' (e.g., 100% inspection vs AQL sampling).
2. Select specific metrology tools (CMM, calipers, hardness testers) suited for the {{critical_tolerances}}.
3. Design a 'Visual Standard' for identifying {{potential_collateral_damage}} (e.g., comparative photos of acceptable vs unacceptable surface finish).
4. Specify a 'Functional Test' (e.g., pressure test, fit-check) to ensure the rework didn't impact the part's performance.
5. Draft the 'Rework Certification' statement that must accompany the batch.

Constraints

• Reworked parts must meet the original engineering drawing; no 'ghost specs'.
• Must include a check for 'hidden' damage (e.g., internal stress, metallurgical changes if heat was used).

Output format

• Validation Plan Table: Columns for 'Feature to Verify', 'Method', 'Acceptance Criteria'.
• Collateral Risk Checklist: Specific things to look for that aren't on the drawing.
• Approval Block: Signature lines for Quality and Engineering.

Quality bar

• Does the protocol test for the specific risks introduced by the {{rework_procedure}}?
• Is the sampling plan statistically significant for the batch size?
