Hello everybody,
I accidentaly came across your web site while searching for some material on Uncertainty calculation which is an integral part for 17025 certification and i beleive i stumbled upon a GOLD MINE with such experienced people exchanging their views on the topic.
I am working on this project as a student on 17025 certification of a calibration lab. I personally feel its like Quick sand ! ..the more i dig into it the more deeper it gets.
First of all !!...i have a very trivial query
While Calculating uncertainty in a measurement we first classify the factors into type A and B . Now , i have gone thru the examples given in the NIST and EAL guides wherein they have taken eg like dead weight tester and Volume of cylinder wherein the input -output relationship is known . and we can find the affect of input uncertainty on output
eg : In volume , uncertainty in diameter and height dimensions affect the output.
BUT for complex electronic equipment these equations are not given by the manufacturer...then in this case do i just neglect this factor ??
Also i would be really greatful (if possible) whether anyone can tell me the procedure they followed since the eg. given in the books really dont give any insight into the procedure esp for electrical equipments eg Calibrators..
Hope someone would reply.
I would really appreciate any advice regarding the procedure.
