When the lifetime of an item follows an Exponentiated inverted Weibull Distribution, a group acceptance sampling plan based on reduced lifetimes is developed in this article. The minimal number of groups and acceptance number required for a particular group size are determined for a specified consumer's risk and the test termination time. The minimum ratios of the true average life to the prescribed life at a certain producer's risk are determined using the values of the operational characteristic function for various quality levels. Examples are used to demonstrate the conclusions.
