Find the inspection sample size using our AQL Calculation tool.
The AQL Calculator is a convenient and simple tool to calculate the required sample size, just input your Lot Size, Inspection Level, and Inspection Type to find out the exact sample size according to the AQL standard.
Look for your lot size and find your letter based on the General Inspection Level (level II is the commonest). You can also define your Special Inspection Levels (only used for specific checks and testing).
DEFINE YOUR ACCEPTABLE QUALITY LIMIT
Identify your sampling size based on the letter from the previous chart. Define your acceptable quality limits and find the maximum number of critical, major and minor defects. Generally, the limits used ore: critical- 0, major=- 2.5, minor=- 4.
Critical defects are the most serious defect category under the AQL table. Importers typically use a 0 tolerance policy for critical defects (AQL of 0.0). In other words, the entire order will fail inspection if inspectors find a single critical defect in the selected sample size.
