This document presents a chain sampling plan for truncated life tests when product lifetime follows a log-logistic distribution. It provides the minimum sample size needed to ensure a specified acceptance probability while satisfying producer and consumer risks, for various quality levels. Tables 1 and 2 show the minimum sample sizes and operating characteristic functions for the proposed sampling plan for different confidence levels, acceptance numbers, and ratios of test time to scale parameter. For example, a sample size of 10 is required for a confidence level of 0.99, acceptance number of 2, and time-to-scale ratio of 0.942.
