Like ISO 2859-1, ISO 2859-3 is applicable to a continuing series of lots from a single source. Sometimes more economical to use ISO 2859-3 than to use the reduced sampling procedure of ISO 2859-1. ISO 2859-1:1999 Sampling procedures for inspection by attributes - Part 1: Sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot inspection. NOTE 1 In this part of ISO 2859 the terms percent nonconforming (3.1.8 and 3.1.9) or nonconformities per 100 items (3.1.10 and 3.1.11) are mainly used in place of the theoretical terms 'proportion of nonconforming items' and 'nonconformities per item' because the former terms are the most widely used. These schemes are intended primarily to be used for a continuing series of lots, that is, a series long enough to allow the switching rules (9. Sampling schemes designated in this part of ISO 2. Procedures in ISO 2859 Parts 1 to 3 are well suited for acceptance sampling. ISO 28 provides a general introduction to acceptance sampling by attributes and provides a brief summary of the attribute sampling schemes and plans used in ISO 2859-1, ISO 2859-2, ISO 2859-3, ISO 2859-4 and ISO 2859-5, which describe specific types of attribute sampling systems.
