The objective of a measurement is to determine the value of the measurand, that is, the specific quantity subject to measurement. A measurement begins with an appropriate specification of the ...

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 ...

How does Thermo Fisher Scientific's analytical software support the calculation of measurement uncertainty? Wilhelm Sanders: According to DIN EN ISO 17025, it is necessary to calculate the measurement ...

This article follows on from my introduction to uncertainty budgets. In that article, I explained how different sources of uncertainty are evaluated and combined to give the uncertainty of a ...

If you’ve read my previous articles, you probably know that I consider uncertainty evaluation the gold standard for instrument capability studies. You will also know that conventional gage studies can ...

The process of accurate weighing begins with correct and appropriate selection of a balance. The main question is whether the balance chosen will meet the measurement uncertainty budget for the ...

Spanish researchers have defined practical guidelines for short-term ground-based albedo measurements that reportedly entail a maximum of 1.5% yield uncertainty contribution for utility scale bifacial ...
