ISO 17025 Measurement Uncertainty Training & GUM Method Mastery
Training course for estimating measurement
uncertainty for ISO/IEC 17025 accreditation.
•Framework includes:
-
Structured approaches to uncertainty analysis.
-
Identifying uncertainty sources.
-
Determining values and selecting probability distributions.
• Mastery of GUM (Guide to the Expression
of Uncertainty in Measurement) method:
-
Converting uncertainty components to standard uncertainty.
-
Combining components and selecting appropriate k-factors.
-
Accurate calculations of expanded uncertainty.
• Emphasizes evaluation and validation of
results.
• Additional skills for ISO/IEC 17025
accreditation:
-
Creating uncertainty budgets and automated Excel calculators.
-
Developing scope of accreditation documentation.
-
Formulating CMC (Calibration and Measurement Capability) uncertainty prediction
equations.
-
Reporting uncertainty in official documents.
• Type A and Type B Evaluations of Standard
Uncertainty:
-
Type A: Statistical methods for assessing variability in repeated measurements.
-
Type B: Scientific judgment evaluations, including calibration and instrument
specifications.
• Reporting Results: Importance of
consistent presentation of measurement results and associated uncertainties.
• Step-by-Step Procedure for Evaluation of
Measurement Uncertainty: Structured approach for identifying contributors and
calculating uncertainties.
• Discussion of calibration, measurement
capability (CMC), coverage factors, and characteristics of uncertainty types.
• Covers measurement equations, sources of
error in calibrations, and uncertainties in various fields (electrical, mass,
temperature, dimensional, and pressure).
• Methods for expressing uncertainty for a
range of values and conformity assessments with specifications.
• Focus on uncertainties related to test
results and methods for comparing independent test results using the En ratio.
