The Uncertainty Workshop program is used to analyze the uncertainty of physical measurements and calibrations. The analysis and computations follow the rules of the of the official documentations:
- ISO Guide to the expression of uncertainty in measurement
- Supplement 1 to the” Guide to the expression of uncertainty in measurement”
- EA-4/02 Expression of the Uncertainty of Measurement in Calibration
- DKD-3 Angabe der Messunsicherheit bei Kalibrierungen
- EURACHEM/CITAC Guide, Quantifying Uncertainty in Analytical Measurement
- ANSI/NCSL Z540.2 - U.S. Guide to the Expression of Uncertainty in Measurement.
- NPL Report DEM-ES-010 Software specifications for uncertainty evaluation.

For this reason the software is compliant with the demands of the standards:
- ISO/IEC/EN 17025:2005 concerning the evaluation of the measurement uncertainty
- ISO/EC/DIN 15189:2007 concerning the evaluation of the measurement uncertainty in the medical-analytical sector
- ANSI/NCSL Z540.3-2006 - Requirements for the Calibration of Measuring and Test Equipment.

The Uncertainty Workshop program uses two different methods to calculate the measurement uncertainty:
- uncertainty propagation, which has been described extensively in the GUM framework.
- Monte-Carlo method, which has been detailed in the first GUM-supplement.

Most important features:
- Suitably for linear and not linear models
- Support of symmetrical and asymmetrical distributions of the output quantities
- Unlimited number of input and output quantities
- Probability distributions: Normal, Lognormal, t, Rectangular, Triangular, Trapezoidal, U-shaped, Cosine, 1/2 Cosine, Quadratic
- Direct and indirect methods of observation
- Monte-Carlo trials from 10 000 up to 10 000 000
- A histogram plot and statistical evaluation

Uncertainty Workshop is the most cost-effective measurement uncertainty analysis tool for achieving compliance with ISO 17025 and ANSI/NCSL Z540.3.
