Editor’s Note: This is part two of a two-part series.
My last column gave the background to an extensive study of results on the calibration of some thread plug gages. As noted last month, the study results were similar to those I’ve encountered before with similar tests. Where measurement uncertainties are quoted in the following notes, remember they are all plus/minus values. As you read the numbers please remember that I am only reporting them—I didn’t create them—so send your emails of outrage or disbelief to someone else.
