What AQL Actually Means
AQL (Acceptance Quality Limit) is the worst tolerable…
AQL is for defects, not every measurement…
Which AQL Level Should You Use?
For apparel, three levels cover almost every buyer…
| AQL level | Use for | Typical buyer |
|---|---|---|
| AQL 1.0 | Premium, brand-critical | Established brands |
| AQL 2.5 | Standard commercial | Most mid-market |
| AQL 4.0 | Basic, promotional | Promo, giveaways |
How Sample Size Is Decided (Inspection Level II)
AQL plans use a statistical table…
| Lot size (pcs) | Sample size | Max defects @ 2.5 |
|---|---|---|
| 2 – 8 | 2 | 0 |
| 9 – 15 | 3 | 0 |
| 151 – 280 | 20 | 1 |
| 501 – 1,200 | 32 | 2 |
| 3,201 – 10,000 | 80 | 5 |
| 35,001+ | 200 | 14 |
