I'm used to seeing sampling tables such as the old MIL-STD-105E that specifies a sample size based upon an AQL. We have a customer who requested the following:
number of lots = 2, number of pieces per lot is approximately 510
Surface roughness evaluations on enough pieces to allow for the following
1. 95% confidence interval that no more than 5% of the pieces in the lot will fail to meet the surface roughness criteria being evaluated for.
I've Googled what I can and came up with nothing useful. Any suggestions on how to calculate the sample size?
