Work out sampling plan (aql) instantly with clear inputs, formula shown and shareable results.
Attribute sampling plans in the ANSI/ASQ Z1.4 tradition pick a sample size from the lot size and inspection level, then set an acceptance number from the AQL. This calculator reproduces that logic and adds the Poisson operating-characteristic point so you can see the producer's risk built into the plan.
Acceptance number
Ac = round(Sample size x AQL %)
Operating characteristic
P(accept) = sum of Poisson(k; Sample x AQL) for k = 0..Ac
No. Sample size grows far more slowly than lot size, because the discriminating power of a sample depends mainly on the sample itself.
No — it is the worst average quality that will still usually be accepted. Treat it as a contractual floor, not a target.
