適用范圍：1.1 This part of ISO 2859 specifies an acceptance sampling system for inspection by attributes. It is indexed interms of the acceptance quality limit (AQL).Its purpose is to induce a supplier through the economic and psychological pressure of lot non-acceptance to maintaina process average at least as good as the specified acceptance quality limit, while at the same time providing an upperlimit for the risk to the consumer of accepting the occasional poor lot.Sampling schemes designated in this part of ISO 2859 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.1.2 These schemes are intended primarily to be used for a continuing series of lots, that is, a series long enough toallow the switching rules (9.3) to be applied. These rules provide:a) a protection to the consumer (by means of a switch to tightened inspection or discontinuation of samplinginspection) should a deterioration in quality be detected;b) an incentive (at the discretion of the responsible authority) to reduce inspection costs (by means of a switch toreduced inspection) should consistently good quality be achieved.Sampling plans in this part of ISO 2859 may also be used for the inspection of lots in isolation but, in this case the useris strongly advised to consult the operating characteristic curves to find a plan that will yield the desired protection (see12.6). In that case, the user is also referred to the sampling plans indexed by limiting quality (LQ) given in ISO 2859-2.
