Z Sequential sampling

Sampling system containing single, double, multiple and sequential sampling plans, indexed by AQL, for inspection by attributes, primarily for use with a continuing series of lots. Acceptance criteria are given and operating characteristic curves included to illustrate the risks involved. Guidance on use is given in BS 6000.
