Sampling procedures for inspection by attributes - Part 1: Sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot inspection

This document specifies an acceptance sampling system of single, double, and multiple sampling plans for inspection by attributes. This document specifies sampling schemes indexed by acceptance quality limit (AQL) for inspection by attributes.Its purpose is to incentivize the producer through the economic and psychological pressure of lot non-acceptance to maintain a process average at least as good as the specified acceptance quality limit, while at the same time providing an upper limit for the risk to the consumer of accepting the occasional poor lot.Sampling schemes designated in this document are applicable, but not limited, to inspection ofitems, such as complete products, sub-assemblies or individual components,operations,materials in process,supplies in storage,maintenance operations,data or records, andadministrative procedures.

Sampling procedures for inspection by attributes - Part 1 : sampling schemes indexed by acceptance quality limit (AQL) for lot-by-lot inspection

Les procédures d'échantillonnage contenues dans la présente partie de l'ISO 2859 sont applicables, mais d'une manière non limitative, aux contrôles de différents domaines tels que: -produits Unis -composants ou madères premières -opérations -matériels en cours de fabrication -fournitures en stock -opérations d'entretien -informations ou enregistrements -procédures administratives. Ces procédures sont principalement destinées au contrôle de séries continues de lots, c'est-à-dire de séries suffisamment importantes pour permettre l'application des règles de modification du contrôle. Ces règles ont pour but: a) d'assurer la protection du client en cas de détection d'une détérioration de la qualité (par le passage à un contrôle renforcé ou l'interruption du contrôle); b) de constituer une incitation à réduire les coûts de contrôle (à la discrétion de l'autorité responsable) si la qualité se maintient continuellement bonne (par passage à un contrôle réduit). Les plans créchantillonnage de la présente partie de l'ISO 2859 peuvent aussi être utilisés pour le contrôle de lots isolés mais, dans ce cas, l'utilisateur doit avoir soin de consulter les courbes d'efficacité afin de trouver un plan qui lui donnera la protection désirée. Dans ce cas, l'utilisateur est également renvoyé aux plans d'échantillonnage indexés d'après la qualité limite (QL) spécifiés dans l'ISO 2859-2.
