QMSys GUM Standard offers calculation of measurement uncertainty for linear and nonlinear models with symmetric distribution of the output quantities. It is a quick and reliable tool, which provides a wide variety of features and functions that enhance the measurement process and optimizes of the measurement procedures. The software uses GUM uncertainty framework for linear models, and GUM uncertainty framework for non-linear models for calculation of the measurement uncertainty.
The analysis and calculations comply with the official documentations:
- ISO/IEC Guide 98-3:2008 (GUM:1995) Guide to the expression of uncertainty in measurement
- ISO/IEC Guide 98-3:2008/Suppl. 1:2008 Supplement 1 to the "GUM" - Propagation of distributions using a Monte-Carlo method
- ANSI/NCSL Z540.2 U.S. Guide to the Expression of Uncertainty in Measurement
- EA-4/02 Expression of the Uncertainty of Measurement in Calibration
- DAkkS-DKD-3 Expression of the Uncertainty of Measurement in Calibration
- UKAS M3003 Expression of Uncertainty and Confidence in Measurement
- EURACHEM/CITAC Guide CG 4 Quantifying Uncertainty in Analytical Measurement
- VDA Band 5 Measuring Process Suitability
- ASME PTC 19.1-2005 Test Uncertainty
- ISO 14253-1 - Decision rules for proving conformance or non-conformance with specifications
- ANSI B89.7.3.1 - Guidelines for decision rules: Considering measurement uncertainty in determining conformance to specifications
- EURACHEM - Use of uncertainty information in compliance assessment ISO/IEC/EN 17025
Furthermore, the software editions also provides accuracy and validity of the results even in cases that are not described in GUM and GUM Supplement 1, e.g. non-normally (non Gaussian) distributed input quantities; correlated input quantities with finite degrees of freedom; nonlinear models with non-normally distributed input quantities.
The software offers numerous valuable features, such as:
- Direct and indirect methods of observation, unlimited number of input and output quantities and large number of probability distributions
- Expert analysis that performs an advanced analysis of the model and determines the appropriate methods for the following calculation of the uncertainties
- Unlimited number of input and output quantities
- Histogram plot and statistical evaluation of sampled data
- A large number of probability distributions for input variables
- Approaches for optimization of the measurement procedures and minimizing the uncertainty of new and existing measurement processes
- The user can create new or adapt existing templates for the uncertainty reports by using a text editor, e.g. Microsoft Word
- Regular updates and upgrades
- Multi-language, flexible and user-friendly interface with a lot of examples
- Professional Customer Support
The full version of the software can be evaluated free of charge for a trial period with a time duration of 3 months.
