Larry Gradin did a good paper on applicability of measurement uncertainty to EMC laboratories at the 2003 EMC Symposium:
Kohler, J.L., Gradin, L.P., "Test laboratory position for expression of uncertainty and confidence in measurement", Electromagnetic Compatibility, 2003 IEEE International Symposium on ,Volume: 1 , 18-22 Aug. 2003, Pages:292 - 297 vol.1 It should also be available upon request at: http://www.integrity-solutions.org/useful.html This is a good place to start to familiarize yourself with all (and I mean all!) the standards involved with this type of work. I will mention that this paper also takes a much less stringent view than the UKAS, but since Larry has been an A2LA auditor in the US, his conclusions should be well supported in accredidation circles.

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.
