A much enlarged second edition of Measurement Uncertainty: A Reintroduction, by Antonio Possolo (NIST) and Juris Meija (NRC Canada) was released April 6, 2022. An inter-American collaboration, the publisher is Sistema Interamericano de Metrologia (SIM) […]
The PSL Uncertainty Calculator is developed by the Primary Standards Lab at Sandia National Laboratories to calculate the combined uncertainty of a system of multiple input parameters. In general, a measurement value is calculated from […]
by Hening Huang This technical note reports a case study that addresses a challenge of interlaboratory consensus building called for by Possolo (2020). The consensus value is estimated as a weighted-average (WA) and the associated […]
by Henry Zumbrun There is a bit of a disconnect regarding risk mitigation practices in the metrology and calibration provider community. Most likely, this comes from a misunderstanding of terminology or legacy requirements that have […]
This introduction to measurement uncertainty is intended for metrology professionals working in calibration laboratories and metrology institutes, as well as students in tertiary-level science and engineering programmes. The subject matter is presented with an emphasis […]
by John Hurll Volume 16:4, Oct-Dec 2009 It is often the case that it will be necessary to provide information in calibration reports about whether or not the stated results for general purpose test and […]
by Dave Abell and Jon Moens Volume 9:4, Oct-Dec 2002 Calculating measurement uncertainties for a single parameter such as DC voltage is relatively straightforward, but to do so for a complex microwave spectrum analyzer that […]
by Jeff Gust Volume 7:5, Sep-Oct 2000 As metrologists are acutely aware, when one transfers a measured value such as resistance, they also transfer a measurement uncertainty that is associated with the calibration of the […]
