Acceptance sampling uses statistical sampling to determine whether to accept or reject a production lot of material.
Acceptance sampling is used to determine if a production lot of material meets the governing specifications.

Sampling plans, such as MIL-STD-105, were developed by Harold F. Dodge and others and became frequently used as standards.
Harold Dodge is universally known for his work in originating acceptance sampling plans for putting inspection operations on a scientific basis in terms of controllable risks.

Pre-shipment acceptance sampling, involving inspection and acceptance testing, may be agreed upon between a buyer, a supplier, and a bank, and it can be used to initiate payment under a letter of credit.
