Re: C=0 vs. AQL MIL Standard 105 E - Sampling Plans
One thing you could use the Z1.4 (ie MIL-STD-105) for is to "work backwards" to find a sampling plan that corresponds to what you are doing anyway; or corresponds to what you need.
For example, if sampling 32 units sounds good, then you could look in Table II-A (Single sampling plans for normal inspection) and see that a c=0 plan for 32 units is AQL = 0.4 and the code letter is "G".
Looking back at Table I, you could find that "G" corresponds to General inspection level II for any batch up to 280 items. So now you know that for any batch up to 280 items, the C=0, n = 32 sampling plan is indeed AQL 0.4, General Level II, Single Sampling Plan for normal inspection of lots up to 280 units (or it is Level I for lots up to 500; or Level S-2 for any size lots).
Looking ahead to Table X-G, you can find the OC curve for this plan. For example, this plan has a 95% chance of accepting lots with 0.16% nonconforming, and a 5% chance of accepting lots with 8.94% nonconforming. This table lets you determine the actual alpha and beta risks for the plan you are considering.
If the plan you were considering doesn't match your expectation for alpha and beta risk, then you can go back and redo this all for a different row (ie different sample size) in Table II-A.
