Acceptance sampling uses statistical sampling to determine whether to accept or reject a production lot of material. It has been a common quality control
technique used in industry and particularly the military for contracts
and procurement. It is usually done as products leave the factory, or in
some cases even within the factory. Most often a producer supplies a
consumer a number of items and decision to accept or reject the lot is
made by determining the number of defective items in a sample from the
lot. The lot is accepted if the number of defects falls below where the
acceptance number or otherwise the lot is rejected.
In quality control, the statistical procedure employed in determining whether to accept or reject a production batch. If the proportion of the units having a certain negative characteristic exceeds the acceptable limit for a given batch, it is rejected.
Two types of acceptance sampling are (1) Attributes sampling, in which the presence or absence of a characteristic in the inspected item is only taken note of, and (2) Variable sampling, in which the presence or absence of a characteristic in the inspected item is measured on a predetermined scale.
Acceptance sampling is used by industries worldwide for assuring the quality of incoming and outgoing goods. Acceptance sampling plans determine the sample size and criteria for accepting or rejecting a batch based on the quality of a sample, using statistical principles. Many organizations require the use of ISO standards (or their ISO/ANSI/ASQC/BS/Military Standards or other counterparts) for purposes of certification.
