In variables sampling, there are single, double, and sequential sampling plans.

Acceptability constant
A constant useful in acceptance sampling set depending on the acceptance quality limit specified value and the sample size. It is part of an acceptance sampling plan by variable as the criteria for lot acceptance.
Acceptance number
The largest number of nonconformities or nonconforming items within a sample for acceptance sampling by attributes, permitting the acceptance of the lot as detailed in the acceptance sampling plan.
Acceptance sampling procedure
The operational requirements/instructions for a particular acceptance sampling plan, including the method of selection, withdrawal, and preparation of samples.
Acceptance value
Used with an acceptance sampling plan by variables as a limiting value of the sample average that enables the meeting of the acceptability constant.
Consumer’s risk quality
