Inspection of a sample from a lot to decide whether to accept that lot. There are two types: attributes sampling and variables sampling. In attributes sampling, the presence or absence of a characteristic is noted in each of the units inspected. In variables sampling, the numerical magnitude of a characteristic is measured and recorded for each inspected unit; this involves reference to a continuous scale of some kind.
A form of sampling used to determine a course of action. A procedure that gives a specified risk of accepting lots of given quality.
a statistical procedure for accepting or rejecting a batch of merchandise or documents; involves determining the maximum number of defects discovered in a sample before the entire batch is rejected
A quality control procedure in which a sample is taken and a decision to accept or reject a whole lot is based on a calculation of sample risk error.

Inspection of a sample from a lot to decide whether to accept or not accept that lot. There are two types - attributes sampling and variables sampling.
Use of a random, representative portion of a sample to determine the acceptability of the whole.
Acceptance Sampling is used to decide whether to accept or reject a production. It is performed once the production lot has been completed and packed. The basic procedure of Acceptance Sampling is:- Take a lot of product.- Select a sample from the lot.- Inspect the units in the sample.- Use the result to decide whether to accept or reject the lot. To learn more about Acceptance Sampling Methods, please view AsiaInspection Quality Standards.
1) The process of sampling a portion of goods for inspection rather than examining the entire lot. The entire lot may be accepted or rejected based on the sample even though the specific units in the lot are better or worse than the sample. There are two types: attributes sampling and variables sampling. In attributes sampling, the presence or absence of a characteristic is noted in each of the units inspected. In variables sampling, the numerical magnitude of a characteristic is measured and recorded for each inspected unit; this type of sampling involves reference to a continuous scale of some kind. 2) A method of measuring random samples of lots or batches of products against predetermined standards.
