Accuracy is a desirable aspect which is conceptually well defined. There are some definitions available for ‘accurate measurement’ in the ISO vocabulary of metrology terms. According to them, a ...

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 striking features of quantum physics is that certain properties cannot both be known or measured with arbitrary precision at the same time. Every measurement may inevitably affect the ...

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 ...

Researchers from the Polytechnic University of Madrid and Qualifying Photovoltaics, a Madrid-based PV engineering consultancy, have provided a series of practical recommendations for short-term ground ...

(Nanowerk Spotlight) Standards, in a scientific context, have a much larger role in our society than just agreeing measurements. As the British Standards Institution (BSI) explains it, put at its ...

On September 27, Mike Howard, the President and founder of Liberty Laboratories and World Cal, will teach a full-day seminar covering Measurement Uncertainties (Muc). Howard will explain ISO 17025 Muc ...

All measurements are subject to error. When a reportable value is derived from a measurement or series of measurements, this value is only an estimate of the “true ...

Improvements to the SI are helping to evolve the science of accuracy and measurement. Democratization of the SI creates a traceability calibration chain accessible to anyone, anywhere. Digitization of ...
