Guidance on Uncertainty Budgets for Force Measuring Devices Part 2. Calculating Uncertainty in Accordance with ASTM E74 Standard Calculating Uncertainty in accordance with ASTM E74 Standard Background: ASTM E74 Standard Practice of Calibration of Force-Measuring Instruments for Verifying the Force Indication of Testing Machines is the standard followed by many in North America for the […]
Guidance on Uncertainty Budgets for Force Measuring Devices Part 1. Why Do We Need a Solid Guidance Document? Uncertainty Budgets for Force Measuring Devices Introduction: All calibration laboratories accredited to ISO/IEC 17025 must submit uncertainty calculations for the Calibration and Measurement Capability uncertainty claims included in the scope of accreditation. The assumptions made to determine the uncertainty […]
What Happens When You Overshoot a Test Point? Various calibration laboratories use hydraulic, screw, and other force calibration machines where it is difficult not to overshoot a test point. By talking about overshooting a test point, we are referring to loading past the desired point and then letting the creep in the hydraulic system naturally […]
