Sampling procedures for inspection by attributes

ISO 2859-3 provides skip-lot procedures for use when the process quality is markedly superior to the AQL for a defined long period of delivery or observation. When the quality level is in this state of excellence it is sometimes more economical to use ISO 2859-3 than to use the reduced sampling procedure of ISO 2859-1.
