Learning outcomes

Knowledge you can put to work.

Connect the subject to the responsibilities and decisions people encounter in their roles.

  • Explain what measurement uncertainty is and what ISO/IEC 17025 asks for
  • Define the measurand and model, and list the sources of uncertainty
  • Evaluate Type A and Type B components and combine them
  • Calculate expanded uncertainty and report it correctly
  • Apply a decision rule when stating conformity
