Item Subject: Measurement Uncertainty
Greeting Tregers;
There seems to be a requirement that, when giving a measured value, there
must be an uncertainty associated with that value describing the confidence
of that value.
(1) Do most labs report an uncertainty measurement in the test report, on
the data sheet, on a certificate of compliance?
(2) How did you generate the measurement of uncertainty for emission
tests? For immunity tests?
AND MOST IMPORTANTLY
(3) What do you tell the customer when he is below the limit by less than
the measurement uncertainty? When he is above by less?
