A reader emailed me after reading some of my rants on thread ring gages dealing with the problems that come up in their use and calibration. But he added another dimension to the problem since he is in the calibration business: How do the Europeans deal with their solid thread ring gages?
The term ‘proficiency testing’ is one that every accredited calibration laboratory is quite familiar with. In basic terms it refers to a method of evaluating how well a laboratory is doing a particular calibration with respect to its claimed measurement uncertainty and how it fares with other participants.
Exova Group plc, the global testing, calibration and advisory services provider, acquired Insight NDT Limited (Insight), a South Yorkshire-based non-destructive testing (NDT) and radiographic inspection business.
If you’re having problems with thread measurements but the answers you’re getting from your usual sources aren’t solving them, it’s natural that you would try and get some unbiased advice from a specialist.
Every industry has a jargon of its own and dimensional metrology is no different. The reason is ease of verbal communication, but that communication can be confusing at times for the uninitiated.
In the dimensional metrology field, gage blocks are the universally used physical standards to which most linear dimensions are compared directly or indirectly.
