by Henry Zumbrun One might read the headline and think why is mV/V or a calibration curve relevant to me or my instrumentation? If you use load cells or other instrumentation that are calibrated using […]
By Hening Huang A variety of statistical methods are available for estimating consensus values in interlaboratory studies (including key comparisons). These methods, although developed based on different approaches and ranging from simple to complex, produce […]
By Dennis Destefan and William Hinton It is well accepted in the metrology community that industry does not have a sustainable source of trained calibration professionals. We explore the availability of metrology-related training and its […]
By Hannah Eilers Where can you find the latest metrology news and information, introductory to NMI-level training, and valuable industry connections? All of this can be achieved at annual trade shows. And believe it or […]
by Manuel Rodríguez In this paper, the Probability of Pass (PoP) and the Probability of Fail (PoF) are derived following a metrological approach, in which concepts such as repeatability, number of effective degrees of freedom, […]
by Henry Zumbrun Aircraft and truck scales come in all different shapes and sizes and typically serve one purpose, to approximate the weight of an aircraft or truck. Why might that be important? For aircraft, […]
by Pedro Adame One of the newest, hence less studied standards for calibration is the ANSI/NCSL International Z540.3 standard. The main difference with the more known ISO/IEC 17025 standard is the need to estimate and […]
