The Quality Toolbox is a reference guide offering well-known and less commonly used quality control tools. The matching is sufficient to allow inspection under either standard for stated AQLs and inspection levels with reasonably equivalent protection.

This standard is an acceptance sampling system to be used with switching rules on a continuing stream of lots for AQL specified. The existence of an American National Standard does not in any respect preclude any-one, whether he has approved the standard or not, from manufacturing, marketing, purchasing, or using products, process-es, or procedures not conforming to the standard.

An American National Standard is intended as a guide to aid the manufacturer, theconsumer, and the general public. From Tables A-2 and D-3 it is seen that a sample of size 10 is required. Ample evidence exists that the productsubmitted for inspection is selected by the supplier to meetA7.
