GENERAL APPROACH TO THE EVALUATION OF MEASUREMENT UNCERTAINTIES Benoit Savanier CETIAT 25 avenue des Arts 69100 VILLEURBANNE France benoit.savanier@cetiat.fr ABSTRACT Since 1995 with the first edition of the GUM by Joint Committee Guide for Metrology, (JCGM) expression of uncertainty in measurement takes a large part in measurement activities. To be able to give a measurement result with a sound uncertainty expectation, different approaches exist that were covered in several linked documents depending of the available measurement model. In ...

Appendix Uncertainty of declared quantity is processed in accordance with recommendation JCGM 100:2008 "Evaluation of measwement data - Guide to the expression of uncefiainty in measurement". Uncefiainty of the result, described by a combined standard uncertainty on confidence level P : 68,27 %, is expressed as a square root ofthe sum ofthe second power oftlpe A and tlpe B standard uncertainties. Type A standard uncertainty is experimental standard deviation of the mean s; ofa set of ...
