19、s Policy Committee. This standard is identical with ISO 8422:1991 Sequential sampling plans for inspection by attributes, published by the International Organization for Standardization (ISO). It includes Technical Corrigendum No. 1 which was published on 1 September 1993. Annex A, Annex B and Annex
20、 C form an integral part of this British Standard. Annex D is for information only. BS 6001 is published in the following Parts. Part 1: Specification for sampling plans indexed by acceptable quality level (AQL) for lot-by-lot inspection; Part 2: Specification for sampling plans indexed by limiting
21、quality (LQ) for isolated lot inspection; Part 3: Specification for skip-lot procedures; Part 4: Specification for sequential sampling plans. It is envisaged that Part 0 will be published identical with ISO 2859-0, which is in preparation. A British Standard does not purport to include all the neces
22、sary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-references International StandardCorresponding British Standard ISO 2859-1:1989BS 6001 Sampling
