This paper is concerned with acceptance sampling systems when a small sample size are necessary or desirable. For example, when production quantities are small or when inspection is either costly or destructive. Under these conditions, a sampling plan with small sample size is not very effective, since discrimination between good and bad quality is not sufficient. Nor does the lot-by-lot inspection provide an incentive for the producer to turn out consistently good quality. Hence it is intended to adopt one plan suspension system with Special Type of Double Sampling Plan (STDS) as the reference plan. When a single plan is used with a suspension rule, the system is called a One Plan (OP) suspension system. In OP suspension systems, a lot- by-lot sampling plan is used in the usual way to decide whether individual lots shall be accepted or rejected. The Reference Quality Level (ReQL) is the quality level which represents standards of quality, taking in to consideration production demands, specifications, costs or other significant factors. Tables are provided for easy selection of the plan. Illustrations are also provided for ready made selection of parameters for one plan suspension system
