Tolerance

From ColorWiki

The amount of acceptable difference between a known correct standard and a set of measured samples.

Tolerances can be divided between warning levels, and out-of-specification (or out of acceptability).
For example, a measurement of a control strip might be said to be out of tolerance if the highest difference between the sample and the color aim is over 6 dE.
