Examples of the Acceptable Quality Level (AQL)
Example
Single Sampling| 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%.
| Sample | Sample Quantity | Result |
| 1 | 5 pieces | Good |
| 2 | 10 pieces | Bad |
| 3 | 15 pieces | Good |
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.
Continuous Sampling| Acceptable Quality Level | 60 % |
| Order Quantity | 300 pieces |
| Frequency | 100 pieces |
| Sample size | 10 pieces |
| Sample no | Sample Size | Actual Quality Level |
| 1 | 10 pieces | 70 % bad |
| 2 | 10 pieces | 50 % good |
| 3 | 10 pieces | 80 % bad |
Compare the results to the Acceptable Quality Level.
| Sample | Quality Level | Quantity |
| - | Actual | Acceptable | Accepted | Rejected |
| 1 | 70 % | 60 % | 0 | 100 pieces |
| 2 | 50 % | 60 % | 100 pieces | 0 |
| 3 | 80 % | 60 % | 0 | 100 pieces |
| - | - | Total | 100 pieces | 200 pieces |
