What is the acceptable quality level for Aql?
The standard AQL levels used to determine the sample size and the maximum allowed number of defects are: AQL level II from table 1. Acceptable Quality Level 2.5 for major defects from table 2. Acceptable Quality Level 4.0 for minor defects from table 2.
What should the AQL standard be for minor defects?
Most importers use the AQL standard of 4% for minor defects. Each defect is not interpreted similarly by all inspection companies. But, importers and suppliers can agree on an AQL standard that is acceptable to both parties based on the level of risk they assume.

Is the Aql table the same as the sampling plan?
But, the AQL chart is just as easy as the AQL sampling plan table. Table 1 on the AQL chart is Sample Size Code Letters, which is divided into three columns for lot or batch size, special inspection levels, and general inspection level. The special inspection levels column is reserved for particular types of product testing.
How many defects are acceptable in the Aql table?
On the AQL columns, you line up your AQL sample size of 125 units with the appropriate levels. If you are ordering consumer products, you will use 0.0 for critical defects, 2.5 for major defects, and 4.0 for minor defects as the AQL standards. For AQL 2.5 in the chart, 7 major defects are acceptable, and 8 or more major defects are rejectable.
