Inspection time calculator

Estimate how long a lot will take to inspect — 100% inspection or an AQL-style sampling plan — and how many shifts you'll need to clear it.

Sample sizes approximate ANSI/ASQ Z1.4 general inspection levels by lot size, scaled for level I/III — not the exact published table. Time estimates assume inspectors can work the lot in parallel with no dependency between units.
