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 with explanations of everything required to pass an ISO/IEC 17025 audit.
Morehouse Free Uncertainty Spreadsheet to Calculate Calibration and Measurement Capability Uncertainty
Measurement Risk and TUR Calculator Tool - 1 Simple-to-Use Tool: Decision Rules can be difficult to understand, and this worksheet will help simplify things by focusing on measurement risk.
The Morehouse Measurement Risk TUR 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.

The ASTM E74 Coefficient Calculator is free software from Morehouse to help calculate higher-order coefficients per ASTM E74 and ISO 376. E74 Coefficient Calculator contains macros because it uses visual basic coding to generate the coefficients.
Measurement Risk Calculator: This calculator was presented at the A2LA tech forum and NCSLI; this easy-to-use 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. Check out all of our spreadsheets here.
Method B Interpolated Zero Calculator: Use this free calculator to easily interpolate the ending zero throughout your dataset. Compliant with ASTM E74 Method B and ISO 376 for ending zero reduction. Download the Calculator tool by clicking here
Probability of False Accept (PFA) Worksheet: 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.
