The Interim Testing Artifact (ITA) is designed to quickly test CMMs for performance problems so that they can be repaired before significant numbers of good parts are erroneously rejected (or bad parts accepted) by the CMM. Frequent testing using the ITA is designed to supplement, NOT REPLACE, complete CMM calibrations by identifying problems with the CMM between regular calibrations. Such testing is often referred to as interim testing.
