This International Standard specifies sequential sampling plans and procedures for inspection by attributes of discrete items.
The plans are indexed in terms of the producer's risk point and the consumer's risk point. Therefore, they can be used not only for the purposes of acceptance sampling, but for a more general purpose of the verification of simple statistical hypotheses for proportions. The purpose of this International Standard is to provide procedures for sequential assessment of inspection results that may be used to induce the supplier, through the economic and psychological pressure of non-acceptance of lots of inferior quality, to supply lots of a quality having a high probability of acceptance. At the same time, the consumer is protected by a prescribed upper limit to the probability of accepting lots of poor quality.st edition 2017-10 Sequential sampling plans for inspection by attributes Plans d'échantillonnage progressif pour le contr？le par attributs Reference number ISO 28591:2017(E) ？ ISO 2017 ISO 28591:2017(E) COPYRIGHT PROTECTED DOCUMENT ？ ISO 2017, Published in Switzerland All rights reserved.
