AQL testing judges a finished lot from a random sample. Lab testing measures material specimens in a laboratory. This guide explains what each proves, what each cannot prove, and how to order both.
AQL stands for Acceptance Quality Limit. This glossary entry explains the full form, the ISO 2859-1 and MIL-STD-105 origin, how sampling works, and a Bangladesh garment example with acceptance numbers.
AQL is the figure you will see on inspection bookings and reports. It decides how strict the sampling is, but it does not promise a defect-free shipment.
