Acceptable Quality Level (AQL)

The Acceptable Quality Level (AQL) is a statistical measure of the quality of a product or service. It is used to determine the acceptable level of defects in a product or service. The AQL is expressed as a percentage of defects. For example, an AQL of 2.5% means that a product or service is acceptable if it has no more than 2.5% defects.

The AQL is used by businesses to set quality standards for their products and services. It is also used by businesses to determine the acceptability of products or services from suppliers. The AQL can be used to make decisions about whether to accept or reject a shipment of products or services.

The AQL is calculated using a sampling plan. A sampling plan is a set of rules that specifies how to take a sample from a population of products or services. The sampling plan also specifies how to calculate the AQL from the sample data.

There are many different types of sampling plans. The type of sampling plan that is used depends on the specific needs of the business.

The AQL is an important tool for quality control. It can help businesses to ensure that their products and services meet the needs of their customers.

Here are some additional details about the AQL:

* The AQL is based on the concept of a normal distribution. A normal distribution is a bell-shaped curve that describes the distribution of data in a population. The AQL is the point on the normal distribution that corresponds to the acceptable level of defects.
