I tend concur w/Mr Woodgate. Also, I have not had the pleasure of dealing with an NCB auditor that understood the math required for uncertainty equations.
In any case, if the calibration lab is accredited, and if the instrument meets mfr's specs, then the "base" uncertainty will "follow" directly from the mfr's instrument spec. Additional uncertainty must be empiricaly derived, and tables generated, that are based on the uncertainty of a formal procedure submitted for each Type Test, for each authorized test location, and test set-up, for each test location. luck, Brian -----Original Message----- From: Hall, Ken [ mailto:[email protected]] Sent: Thursday, August 19, 2004 11:00 AM To: John Woodgate; [email protected] Subject: RE: Measurement uncertainty procedure Hello, I find this URL: http://www.acemark.com/uncertaintyfrm.htm the best.

Yes, it does, but it takes a very extreme view about how uncertainty should be allowed for in determining compliance. Other bodies have a less stringent view. Even in Germany. -- Regards, John Woodgate, OOO - Own Opinions Only. The good news is that nothing is compulsory. The bad news is that everything is prohibited. http://www.jmwa.demon.co.uk Also see http://www.isce.org.uk ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
