AQL

Acceptable Quality Level

TL;DR

Statistical sampling plan used at incoming and finished-goods inspection — defined by ANSI/ASQ Z1.4 (or ISO 2859). The AQL is the worst-acceptable defect rate the plan will routinely pass.

An AQL sampling plan defines sample size and accept/reject numbers based on lot size and the AQL level (e.g. 0.65% for critical, 1.0% major, 2.5% minor). It is the standard receiving-inspection language between manufacturers and suppliers. Buyers should specify AQL per defect class on every PO.

V5 ships ANSI/ASQ Z1.4 tables built-in: pick lot size + AQL, V5 generates the sample size, prompts the inspector, and renders the disposition (accept / reject / 100% inspect) into the receiving record.
