ISO 2859 is an internationally recognized standard that specifies an acceptance sampling system for inspection by attributes. It is indexed in terms of the acceptable quality level (AQL).
The objective is to induce suppliers to maintain a quality level that is at least as good as the AQL specified by the buyer. At the same time, the system minimizes the statistical risk for a buyer of accepting an occasional poor lot. Blue iris. Sampling schemes designated in this part of ISO 2859 are applicable, but not limited, to the inspection of: • finished products • components and raw materials • materials in process • supplies in storage These schemes are intended primarily to be used for a continuing series of lots, i.e. A series that is long enough to allow switching rules to be applied. These rules provide: • Consumer protection (by means of a switch to tighten inspection) if a deterioration in quality is detected; • An incentive (at the discretion of buyer) to reduce inspection costs (by means of a switch to reduce inspection) if consistently good quality is achieved. Sampling plans in this section of ISO 2859 may also be used for the inspection of lots in isolation; however, the user is strongly advised to consult the operating characteristics curves to find a plan that will yield the desired protection. In which case, the user is referred to the sampling plans indexed by limiting quality (LQ) given in ISO 2859-2.This instruction indicates partial tables of the standard ISO 2859-1.

Indexing is by a preferred series of limiting qualities with a consumer's risk usually below 10% and always below 13%. Procedures are provided to cater for two situations: Procedure A to be used when the supplier and the consumer both wish to regard the lot in isolation (shall be used unless there is a specific instruction to use procedure B), procedure B to be used when the supplier regards the lot as one of continuing series but the consumer considers the lot received in isolation.
