Some interpret it to mean if a lot has AQL percent defective or less, a lot would have a high probability of being accepted based on the sampling plan. The AQL is a parameter of the sampling scheme and should anssi be confused with a process andi which describes the operating level of a manufacturing process. A stable process or production is less about a capability index, and more about the control chart of the data showing a stable process. Where do x1.4 values come from and what do they mean? Answer FDA does not and can not tell you what sampling plan is to be used. The second question, is one that you have to understand how well do you follow the acceptance sampling process?
