Measurement Uncertainty Budgets
This workshop presents a combination of lecture and classroom exercises to demonstrate the principles of measurement uncertainty analysis.
Measurement Uncertainty Budgets
This course covers measurement uncertainty, statistical concepts, and ISO 17025 compliance. Learn to calculate uncertainty, analyze data, and apply the ISO GUM for accurate, reliable measurements.

Course Objectives
- Understand the importance of measurement uncertainty and its impact
- Understand key statistical concepts and terminology
- Ensure compliance with ISO 17025 requirements
- Perform computations and analyze measurement data
- Review and apply the ISO Guide to the Expression of Uncertainty in Measurement (GUM)
Target Audience
- Calibration Technicians
- Quality Managers
- Engineers
- Quality Technicians
- Other users of uncertainty budgets
