The final section mandates temperature uniformity surveys (TUS) and system accuracy tests (SAT). Without documented proof of these tests, even a perfect plating line scores a zero.
The Automotive Industry Action Group (AIAG) developed the CQI-11 Special Process: Plating System Assessment to provide a common methodology for evaluating suppliers who perform plating (chrome, zinc, nickel, etc.) and anodizing. aiag cqi11 pdf exclusive
Unlike a typical ISO 9001 or IATF 16949 audit that focuses on paperwork, CQI-11 is a technical deep dive. It requires auditors to verify: The goal is simple: Prevent defects like hydrogen
The goal is simple: Prevent defects like hydrogen embrittlement, poor adhesion, or corrosion failure before they reach the assembly line. aiag cqi11 pdf exclusive
During your internal audit, look for the "Red X" (the one variable you ignore). For plating, that is often the anode condition or bagging. CQI-11 requires inspection records for anodes; 90% of suppliers fail this. Ensure your exclusive internal checklist includes a line item for "Anode to Cathode Ratio Log."
