Summary for mil-std-105e sample size Discussion
MIL-STD-105E sample size requirement is the focus of this thread, where Daryl Yeung asked whether an 800-piece lot with Major AQL 2.5 and Minor AQL 4.0 should be inspected using the full 800 pieces or reduced sample sizes from the table. In his follow-up, Daryl said he found that the correct approach is to use a 500-piece sample size, and that the minor inspection should stop after 315 pieces. The thread does not show a competing technical explanation, but the editor’s note adds an important update: MIL-STD-105E was canceled in 2008, and future acquisitions should refer to MIL-STD-1916 or ANSI/ASQ Z1.4 instead. So the practical takeaway is that the table-driven sample size reduction, not an 800-piece full count, was the intended interpretation in this discussion, while the standard itself is now obsolete.
Q. Using MIL-105E single sampling plan, when sampling size is 800, AQL [Acceptable Quality Level] Major-2.5 and Minor 4.0. According to the table, should we decrease the sample size to 500 for major and 315 for minor? How can it be done in actual inspection process? Or in other words, we should stay with 800 sample size but Ac:21 for Major and Minor?
Please provide me with solid evidence.
Thanks,

A. I have found the answer by myself, it should be 500 hundred sample size; however, quantity after 315 pieces should end the calculation of the minor.
