What does AQL refer to in quality control?

AQL stands for Acceptable Quality Limit, which is a statistical measurement used in quality control processes. This concept is vital for determining the maximum number of defective items that is allowable in a batch or lot while still considering the lot acceptable. It assists organizations in deciding whether to accept or reject a production lot based on inspection results.

In quality control, AQL is used in sampling plans and involves the risk associated with acceptance or rejection. It essentially allows manufacturers to establish a balance between risk and quality, defining what is an acceptable level of defects. By setting an AQL, companies can manage expectations regarding quality while still permitting some level of imperfections in their products.

Understanding AQL is crucial for ensuring that quality standards are met without over-investing in inspection processes, thus combining efficiency with quality assurance.
