Guide for Understanding Uncertainties on a Morehouse ASTM E74 Calibration Certificate Reporting the Expanded Uncertainty on an ASTM E74 Calibration Certificate of the measurement is a requirement of ISO/IEC 17025 and likely always will be. However, if you look at several different certificates of calibration, their Expanded Uncertainty reported, contributors and reporting methods will vary […]
100 Years of Morehouse and 100 Blog Posts The 100th blog post, what to do? 100 years in business, 100 blog posts, several papers, and technical articles along the way. Communication has changed from a switchboard phone to a handheld personal computer that can receive this message. From the proving ring to today's deadweight […]
What Calibration Coefficients Do ASTM E74, ISO 376, and other standards may use calibration coefficients to characterize the performance characteristics of continuous reading force-measuring equipment better. These standards may use higher-order fits such as a second or third-order fit (ISO 376) or ASTM E74 allows higher-order fits up to as high as a 5th-order. Both […]
