AQL Sampling Plan
Build a consistent sampling plan that aligns with your product risk and buyer expectations.
A sampling plan documents how many units to inspect, which defects matter most, and how results are judged.
Inspection levels
Inspection levels determine sample size relative to batch volume and risk tolerance.
Defect thresholds
Setting thresholds by defect severity ensures quality decisions are aligned to safety and brand risk.
Step-by-step
- - Map product risk and customer expectations.
- - Select inspection level and AQL thresholds.
- - Train suppliers on the sampling plan before production.
