Definition
Acceptable Quality Level (AQL) is a statistical quality control tool used to determine the maximum number of defective products that can be accepted in a given sample size. It is used to ensure that the quality of a product meets the standards set by the manufacturer. AQL is expressed as a percentage and is calculated by dividing the number of defective products in a sample by the total number of products in the sample.
Importance
AQL is an important tool for manufacturers and suppliers to ensure that the products they produce and sell meet the quality standards set by the company. It helps to ensure that the products are safe and reliable for consumers. AQL also helps to reduce the cost of production by ensuring that only products that meet the quality standards are produced.
Example
For example, a manufacturer may set an AQL of 2%. This means that the maximum number of defective products that can be accepted in a sample size of 100 is 2. If more than 2 products are found to be defective, the manufacturer must take corrective action to ensure that the quality of the product meets the standards set by the company.
