A lot sensitive sampling plan is an inspection procedure that involves a single sample with a zero acceptance number, and it is useful in the areas of compliance and safety-related testing. It is regarded as a consumer-oriented plan and is applied for an individual isolated lot, giving protection in terms of the limiting quality level. A major disadvantage of the plan is that it creates the possibility of the rejection of good lots because of the severity of the acceptance criteria involved in the plan. In this paper, a modified lot sensitive procedure that uses the repetitive group sampling procedure with small acceptance numbers is proposed. It can be considered as an alternative to the lot sensitive single sampling plan. The selection of the plans providing protection to the producer and the consumer in terms of acceptable and limiting quality levels with associated risks is discussed through illustrations. Tables for determining the sample size and the points for the plot of the operating characteristic curves of the plans are constructed using ƒ-binomial approximation to a hypergeometric distribution.
