Describes sampling plans and procedures for inspection by attributes of discrete items. It is indexed in terms of the Acceptable Quality Level (AQL). Aims to induce a supplier through the economic and psychological pressure of lot non-acceptance to maintain a process average at least as good as the specified AQL, but gives an upper limit for the risk to the consumer of accepting the occasional poor lot. Sampling plans are applicable, but not limited, to inspection of end items; components and raw materials; operations; materials in process; supplies in storage; maintenance operations; data or records and administrative procedures. Allows automatic protection to the consumer and incentive to reduce inspection costs.
