Decision view

Accept or reject with clear thresholds

Visual decision cards help inspection teams understand pass/fail limits before going on-site.

PASS outcome

Accept shipment

Major defects: 14 or fewer

The shipment remains within the selected AQL tolerance for major defects.

FAIL outcome

Reject shipment

Major defects: 15 or more

The result exceeds the selected threshold and should trigger corrective action.

AQL overview

What AQL means for product inspections

AQL, or Acceptable Quality Limit, is a statistical sampling approach used to determine how many products to inspect and how many defects can be accepted before a lot is rejected.

What is AQL? A practical decision framework for balancing inspection effort, product risk, and shipment confidence.
Sampling disciplineInspect a representative sample instead of every unit.
Defect severitySeparate critical, major, and minor defect categories.
Decision controlUse clear acceptance and rejection numbers for shipment review.
Why use AQL

A more consistent way to plan inspections

AQL gives quality teams a shared framework for sample planning, defect tolerance, and shipment decisions.

ANSI/ASQ Z1.4 StandardAlign sampling plans with a widely used inspection standard.
Faster Inspection PlanningReduce manual lookup time before the inspection starts.
Clear Accept/Reject RulesGive field teams objective thresholds for findings.
Consistent Quality DecisionsApply the same decision logic across suppliers and shipments.
