What is AQL?
AQL (Acceptable Quality Limit) is the international standard (ISO 2859-1) used for product inspections. It defines the maximum number of defects allowed in a sample for the entire lot to be accepted.
Critical Defects (0)
Unsafe or dangerous products. Zero tolerance.
Major Defects (2.5)
Functional issues that make the product unsaleable.
Minor Defects (4.0)
Aesthetic imperfections that do not affect use.
How to use the calculator?
- 11. Enter your total lot size (e.g., 5000 pieces).
- 22. Select the Inspection Level (General Level II is the industry standard).
- 33. Set AQL limits for Critical, Major, and Minor defects.
