Measurement uncertainty, as described in ISO/IEC Guide 98, is a “parameter, associated with the result of a measurement, [which] characterizes the dispersion of values that could reasonably be ...

Measurement uncertainty represents a fundamental parameter in analytical chemistry, encapsulating the range within which the true value of a measurement is expected to lie. This concept is integral to ...

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 ...

Every year an increasing number of laboratories using OES (Optical Emission Spectroscopy) spectrometers get accredited according to DIN EN ISO 17025. Compliance with DIN EN ISO 17025 has elevated the ...

Based on the EURAMET Calibration Guide No. 18 “Guidelines on the Calibration of Non-Automatic Weighing Instruments” 1–3 (represented as “EURAMET cg-18”), this QApp function offers a dynamic display of ...

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 ...

Calibration determines the accuracy of measuring instruments by comparing its value to a higher-level measurement standard, usually a working standard gage block. Measurement standards follow a ...
