Based on these studies, an investigator can reduce both cost and time by efficiently deciding whether to reject or accept the provided lot. Sampling scheme of acceptance deals with the inspection of product lots and the action taken to reject or accept them, and it is one of the earliest schemesapplied in quality control. In present article, a sampling scheme of group acceptance is proposed with truncated life testing under the assumption that item lifetimes follow half logistic distribution. To a specified size of group, the least required count of groups and the corresponding acceptance count are calculated for given buyer’s risk and test completion time. Operating characteristic numbers are computed for different quality levels, and the least ratios of true mean life to stated life corresponding to a given vendor’s risk are calculated. The findings are demonstrated through illustrative examples. https://jirss.irstat.ir/article_738136_c132acabb20ce1ae73a9866b0997a05b.pdf
