AQL (Acceptable Quality Level):
The standard definition of Acceptable Quality Level (AQL) is
"the maximum defective percent (or the maximum number of
defects per hundred units) that, for purpose of sampling
inspection, can be considered satisfactory as a process
Basically, we will randomly select a sampling size quantity
(based on the AQL tables) to be inspected, and after
inspection, according to the number of defects found (critical,
major, minor defects), we will advice you to accept or to reject
Let's take a hypothetical inspection of a 30 000 pieces lot.
The Table A , under the column level II, gives us the letter M, which
corresponds in the table B to a sampling size of 315 pieces to
inspect. The usual AQL used by people is generally: 0 / 2.5 / 4 for
Critical / Major / Minor defects. For the letter M, 315 pieces to inspect,
the column 2.5 for defects gives us two numbers: 14 & 15. Thus
Among a sampling size of 315 pieces inspected, the maximum number
of major defects authorized is 14.
If we find 15 major defects, you should reject your shipment and / or
perform defect sorting, ask for a re-work of the production or ask for a
replacement of your production. Then you should get your shipment reinspected a second time.
