Acceptable Quality Level (AQL): Definition and How It Works
The acceptable quality level (AQL) measures the worst tolerable quality level for a product, and it differs based on industries and products. AQL works through random sampling quality inspections to determine the number of defective items acceptable, and AQL tables help determine how many defects are allowed for a company to achieve a certain AQL. Defects are categorized based on their quality level, and factors such as lot or batch size, inspection type, and desired AQL are used to determine if AQL is being met. AQL is not standard and varies between products and industries, and it's useful for ensuring large production orders meet quality standards.
