Using Mass Weights to Calibrate Force Devices Can Result in a Large Measurement Error Morehouse Benchtop 10,000 lbf Calibrating Machine When metrologists talk about measurement error, we’re talking about the difference between the nominal value and what the instrument is reading. If 10,000 lbf is applied to a force measuring device and the readout displays […]
New ASTM E74-18 Changes - Intro It’s been five years since ASTM E74 was last updated. The last version of the standard was ASTM 13a, and I believe we may have an ASTM E74-18a. However, the new standard has been released and this blog is going to detail some of the major changes between […]
Guidance on Uncertainty Budgets for Force Measuring Devices Part 4. Calculating Uncertainty for ISO 376 Uncertainty Analysis ISO 376 Uncertainty Analysis Introduction: All calibration laboratories accredited to ISO/IEC 17025 are required to submit uncertainty calculations for the Calibration and Measurement Capability uncertainty claims included in the scope of accreditation. The assumptions made for the determination […]
