GUM, the internationally approved technique for calculating measurement uncertainty, is reliant on the availability of a certified reference sample. Likewise, to find any repeatable offset (systematic ...

The technique which is recommended by the regulatory bodies ISO (International Organisation for Standardisation) and BIPM (Bureau International des Poids et Mesures) is one of the most comprehensive ...

This two-day course gives an introduction to the theory and practice of calculating Uncertainty of Measurement for chemical analysis of foods. The approach to Uncertainty measurement will follow the ...

Peak power meters have long been accepted as accurate measurement standards. But just how accurate are these power measurements? Calculating the accuracy of RF peak power measurements requires more ...

Performing a measurement uncertainty calculation is often seen as problematic. One of the barriers to be overcome in the wider application of measurement uncertainty (MU) to reportable values is the ...

A guide to measurement uncertainty in EMC tests is now available from Schaffner EMC. The guide provides the basic concepts for identifying and calculating contributions to uncertainty as well as ...

A program for calibration and routine testing of weighing instruments ensures accurate results. A measurement of any kind is affected by the errors and uncertainties that exist in that measurement ...

One of the most often quoted, yet least understood, tenets of physics is the uncertainty principle. Formulated by German physicist Werner Heisenberg in 1927, the rule states that the more precisely ...
