I send gages out for calibration and we have a form that's called "Calibration Vendor Requirements" that I need to fill out. I thought putting calibrate per manufacturing specs would be good enough but I guess not.
I e-mailed this to my Quality Manager to see if this is acceptable. "On the calibration of Thread Rings and plug gages, per manufacturing specs is based off of what the Gage labeled size is. I believe they follow ANSI and that is what they calibrate to. So for thread gages, could I say all thread gauges will be calibrated to ANSI standards on the "Calibration Vendor Requirements form"?
He replied. 'Not all threads are ANSI, but I think your point is correct.
You may reference the thread standard of the specific thread type.
This does get sticky however because of revision levels change. So ideally you would name the spec and current rev, however, in most cases you will not know and would be relying on the cal supplier to be up to date. So in this case you should be able to say the spec name and “latest revision” or “current edition” etc.
We have UNC, ACME, NPT threads. Can someone help me understand what standard is used that threads are calibrated to? Or clarify what my quality manager is looking for?
Thanks,
