This work derives the intermittent batch size and sample size for product life testing on a production line. The sequential probability ratio test was adopted to determine the sample size, n, and the expected number of samples (ENS). An inverse chi-square approximation was used to determine the relationship between the degree of freedom, m − 1, and the estimated range of σ 2 (ER σ 2 ) at various (1 − α) levels of confidence. Consequently, ENS and m were used to determine the intermittent batch size, l. Finally, rewritable compact disks (CD-RWs) underwent testing to demonstrate the feasibility and effectiveness of the proposed efficient sampling approach. Copyright
