AQL (Acceptable Quality Limit) is a basic quality control method used in clothing and textile manufacturing. It helps determine if a batch of products meets quality standards by checking a small number of items instead of the whole batch. Think of it like taste-testing a few spoonfuls of soup instead of the whole pot. Quality control inspectors use AQL to decide how many pieces to check and how many defects are acceptable before rejecting a shipment. This system is widely used by brands and manufacturers to maintain consistent product quality while keeping inspection costs reasonable.
