Are you having problems figuring out all of the requirements to calculate a CMC for force uncertainty or torque uncertainty? This excel sheet provides a template to calculate CMCs (force uncertainty) with explanations of everything required to pass an ISO/IEC 17025 audit.
Morehouse Free Force Uncertainty Spreadsheet to Calculate Calibration and Measurement Capability Uncertainty
Decision Rules can be difficult to understand, and this worksheet will help simplify things by focusing on measurement risk. The Morehouse Measurement risk TUR calculator tool will cure those measurement headaches allowing anyone to calculate TUR properly and Measurement Risk Correctly. Use this tool to input parameters such as accuracy requirement, resolution, measurement uncertainty, TUR, and repeatability with other error sources.
The TUR calculator will calculate how good the reference standard uncertainty needs to be to maintain test uncertainty (TUR) ratios and will allow the end-user to input their own risk tolerances. The TUR Calculator can be found here.
Mass to Force Conversion tool solves issues with results not agreeing because the same units are not being used. This mass to force spreadsheet tool was created to help convert mass to force and mass to force.

Want to know how we are calculating expanded uncertainty on force and torque certificates? This spreadsheet has all of the formulas that comply with ILAC-P14:09/2020 ILAC Policy for
Measurement Uncertainty in Calibration at the time of calibration. Calculating Expanded Uncertainty is drastically simplified and easily explained with this tool
The ASTM E74 Coefficient Calculator is free software from Morehouse to help calculate higher-order coefficients per ASTM E74 and ISO 376. ASTM E74 Coefficient Calculator contains macros because it uses visual basic coding to generate the coefficients.
Measurement Risk Calculator presented at A2LA tech forum and NCSLI, this easy-to-use Measurement Risk Calculator tool allows one to determine the effect of the resolution of an instrument on the overall measurement uncertainty and risk. One can use this tool to analyze the effects on TUR and measurement risk as well.
Probability of False Accept - Free Excel Worksheet. Decision Rules can be difficult to understand, but this worksheet will help. Use this tool to input parameters such as accuracy requirement, resolution, measurement uncertainty, and repeatability with other error sources. It will help make decisions on equipment, such as: Should I buy a device with better resolution? Do I need my calibration provider to have better measurement uncertainty than what I am getting? It also provides different Methods, using different decision rules (Method 5 and 6). The PFA calculator contains macros.
