Acceptable Quality Level (or Assured Quality Level)
The AQL is
the quality level which is the limit of a satisfactory process average
(in other words, a standard is set, if you do not meet the standard
you fail the inspection). A sampling plan and an AQL are selected
in accordance with the risk assumed. The inspection will be
approved only if the defects in the batch or lot be no greater then
the designated value of the AQL sampling plan.
Sample : a sample consists of one or more units of product
drawn from a lot or batch. The unit of the sample being selected
at random without regard to the quality. The number of units
of product in the sample is the AQL sample size.
Plan : a sampling plan indicates the number of units of
product from each lot or bach which are to be inspected and the
criteria for determining the acceptability of the lot or batch.
of Product : the unit of product is the item inspected
in order to determine its classification as defective or non-defective.
In other words the item used to count the number of defects.
It may be a single item such as a shirt or a set such as two piece
pajama. Or the unit can be a length of fabric etc. The
unit of product is any item that you wish to inspect.
average is the average percent defective or average number of defects
per hundred units of product committed by the supplier for original
inspection. The original inspection is the first inspection
of a particular quantity of product as distinguished from the inspection
of product which has been resubmitted after prior rejection.
