In recent columns I’ve commented on information requests accompanying calibration orders. Some of these are common and effective but some are not. Occasionally, they are brought about due to their inclusion in one standard or another but are misrepresented. In some cases, the standard they are from relates to in-house systems rather than calibration activities by outside parties.
I offered some comments that relate to gaging problems in the last column but thought it would be worth giving measuring instruments the same treatment.
In my last column I beat up on the calibration of adjustable thread ring gages. Since I’m a nice guy, I thought it only fair that non-adjustable or solid thread ring gage calibration get similar treatment.
