The update to ISO17025 in 2017 contains new requirements for testing laboratories in relation to decision rules and statements of conformance. ISO17025:2017 was updated with the purpose of providing laboratory customers confidence in the results reported. It’s not possible to know the level of risk nor to make a statement of conformance if the measurement uncertainty has not been calculated.

“How certain are you of the measurements in your test report? How well does the result represent the value of the quantity being measured?” Customers often expect testing laboratories to get matching results for the same samples. However, it may be that one laboratory reports a pass result and another reports a fail result. Calibration labs have always been required to determine measurement uncertainty. The situation in testing is still evolving and testing laboratories are faced with numerous difficulties.

This course explains the concept of measurement uncertainty and describes the approaches for estimation of uncertainty within a testing laboratory. It is suitable for those who have previously calculated measurement uncertainty or are at the early stages in this process.

The aim of this programme is to provide delegates an introduction to the tools and knowledge they need to;

a) Select an approach for measurement of uncertainty of their test method

b) Calculate and combine uncertainties

c) Report uncertainty in their test reports

d) Comprehend the relationship between measurement uncertainty, decision rules and statements of conformance.

What's covered?

Expand/Collapse Expand/Collapse

This course will cover;

  • The concept of measurement uncertainty.
  • Sources of uncertainty within the test laboratory.
  • The statistical techniques for calculation of uncertainty.
  • An overview of the various approaches for estimation of measurement uncertainty.
  • The GUM approach for estimation of uncertainty.
  • Single laboratory validation approach
  • ISO19036:2019 approach for estimation of uncertainty in microbiology.
  • A discussion on other evolving guidance for estimation of uncertainty.
  • How to update contract review forms to include agreement with clients on decision rules and statements of conformity.
  • How to report uncertainty and statements of conformity in test reports
  • Completion of a Gap analysis checksheet which encourages trainees to consider the requirements of ISO17025:2017 and is a useful basis for an action plan.

 

The training programme is interactive and applies different training methods and styles to deliver the key messages effectively e.g. discussions, group activities and demonstrations. The training includes practical exercises enabling the trainee to verify their knowledge and skills.

The Tutor is experienced in auditing against the ISO17025:2017 and in supporting laboratories with uncertainty calculations and will share experiences on expectations and outcomes by accreditation assessment bodies and laboratory clients.
