AQL, or Acceptable Quality Level, is a statistical measurement used in quality control. It defines the maximum number of defective items allowed in a sample size during inspections. AQL helps businesses ensure that their products meet quality standards while minimizing costs associated with excessive inspections. In practice, AQL is often used in manufacturing and production processes. Companies set specific AQL standards based on their quality requirements, which guide inspectors in determining whether a batch of products is acceptable or should be rejected. This method balances quality assurance with operational efficiency.
