Is AQL an acceptable quality limit? The abbreviation of acceptance quality limit, that is, the average quality level of the worst process that can be allowed when continuous batches are sent for inspection. AQL is widely used in product quality testing in various industries, and different AQL standards are suitable for testing different substances.
In AQL sampling, the number of samples is the same. The smaller the value after AQL, the fewer defects are allowed, indicating that the higher the quality requirements, the stricter the inspection.
Extended data:
AQL theory is based on statistical assumptions, that is, everything is biased, for example, the rate of surgical accidents cannot exceed a few percent, and the rate of mail delivery errors cannot exceed a few percent.
AQL is the basis of the adjustable sampling system and the upper limit of the process average value of the inspection lots for continuous inspection agreed by both the supplier and the supplier. The process average is the average quality of a series of continuous inspection lots, which is expressed by the batch nonconforming rate or the defective rate per 100 unit.
