Example
| Acceptable Quality Level |
60 % |
| Sample Size |
30 pieces |
AQL 60 % means that 60% of the sample can be defective and the sample would be rejected only if the rejected piece is more than 60%.

| 3 |
15 pieces |

Actual Quality Level = [ 10 / (5+10+15 ) ] x 100% = 33.33 %
The actual defective level is much lesser than the Acceptable Quality level. Consequently, the order quantity or the sample is accepted.
