Applied Measurement Uncertainty for Testing Laboratories (EMU 201)

During this workshop, the participant will be introduced to several tools and techniques that can be applied in the testing laboratory environment to efficiently and effectively create measurement uncertainty budgets which comply with ISO/IEC 17025 requirements. The tools presented are generic in nature such that they may be applied in a variety of testing laboratories.

Course Content

  • Metrology terminology and definitions.
  • Requirements for metrological traceability.
  • Statistical applications using Microsoft Excel.
  • The uncertainty estimation process.
  • Repeatability and reproducibility methods.
  • Development of the test uncertainty budget.
  • Understanding and reporting measurement uncertainty in test reports.


  • Completion of A2LA Introduction to Measurement Uncertainty course (EMU 101), or other basic university/collegiate statistical coursework
  • Working experience in Testing laboratories
  • Proficiency in Microsoft Excel or equivalent


The participant will need to bring a laptop computer with Microsoft Excel or similar spreadsheet installed.


Target Attendees

Laboratory technical managers and test technicians.

Learning Outcomes

After successful completion of the course, participants will be able to:

1.    Discuss the concepts within the Guide to the Expression of Uncertainty of Measurement (The GUM);
2.    List and define the contributors for testing laboratory measurement uncertainty estimates;
3.    Determine how contributors are considered for inclusion in the uncertainty budget; and
4.    Build a basic Test Measurement Uncertainty Budget.
