AQL (Acceptance Quality Limit)
Acceptance Quality Limit
Quality level used in acceptance-sampling plans as a benchmark for a satisfactory process average.
Examples
- 01The customer specifies an AQL of 0.65 for cosmetic defects, which sets a sample of 125 pieces for a lot of 3,000.
- 02During supplier development, the buyer explains that meeting the AQL does not mean defects are acceptable, and pushes for a zero-defect target in serial production.
- 03When repeated lots pass at AQL 1.0 but the line still finds defects, the team switches to a tighter level and asks the supplier for capability data.
