In this paper the authors consider the problem of estimating the number of nonconformances remaining in outgoing lots after acceptance sampling with rectification when inspection errors can occur. Reduced inspection is considered desirable by the responsible authority. We would like to justify that we can abide by level I or even lower if possible.

Ideally, a very fast, effective and non-destructive inspection method is preferred over a slow, error prone, and destructive approach. This standard is also available to be included in Standards Subscriptions. Then, you would pick the AQL you need based on the risk you are willing to take for the process average of percent defective.Īcceptance not permitted at this sample size. If the cumulative number of nonconforming units is equal to or less than the second acceptance number, the lot or batch shall be considered acceptable.
