we are accredited to TS16949 which states that OUTSIDE calibration companies must be 17025. We are thinking about bringing certification of digital micrometers and digital calipers in house next year. There is no requirement to be certified to 17025 internally. What experience to the users here have with self calibrations? What training have you received to do the calibrations? Have you gotten any pushback from Certifying Body auditors?- thanks
Welcome to The Cove, Kybluegrass!
I lived in KY for 5 years.
As a CB auditor I have never pushed back if a company was doing in-house calibrations correctly. I have written multiple nonconformities for companies that did calibrations incorrectly and/or in a way that was different from the way their
calibration methods stated they should be done.
Probably the most common issue I've come across is not calibrating the tool in the way it is used. For example: calibrating calipers only for the OD jaws and not calibrating the ID jaws and depth rod which are both used for inspection.
Having said that, I've also seen outside calibrations done that had similar issues. For example a company sent a force gage out for calibration without specifying what to calibrate. The (ISO 17025 accredited) calibration lab didn't ask for clarification and only calibrated it for tension. The certificate delivered with the gage showed it was only calibrated for tension. The company never checked the certificate to notice this. The gage was only used by the company in compression.
