The sample is divided into various groups in order to develop a group sampling plan in such a way that the life testing experiment is terminated as soon as the first failure in each group is observed. The acceptance criterion based on the theory of order statistics is proposed. http://pubs.sciepub.com/ajams/6/5/2/ajams-6-5-2.pdf single sampling lot acceptance group sampling plan truncated life tests reliability test plans order statistics
