Testing Laboratories within the Food Sector are experiencing a renewed focus on their Estimation of Measurement Uncertainty for tests within their scope of accreditation. There are new requirements within ISO 17025:2017 for reporting of Statements of Conformity to laboratory clients. The Decision Rules used to determine conformity have to be agreed with the client. It is not possible to know the level of risk nor to make a statement of conformance if the measurement uncertainty has not been calculated. The LabCred Accreditation and CLAS Accreditation requirements align with the updated requirements in ISO17025:2017, with the purpose of providing confidence in the results reported.

“How certain are you of the measurements in your test report? How well does the result represent the value of the quantity being measured?”

This course explains the concept of measurement uncertainty and describes the two main approaches for estimation of uncertainty for testing laboratories in the food sector. 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.
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 course will focus on the following approaches:

    • Use of Single Lab Validation & QC data (ideally the lab can utilise existing data for estimation of measurement uncertainty)
      Experimental data from Reproducibility Replicates using approach outlined ISO19036:2019 (microbial counts in the food chain). Micro presents unique challenges as the measurand is a living organism and the approach outlined in ISO19036 recognises this.
    • 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.
    • How to interpret and trend external proficiency test results.
    • Completion of a Gap analysis checksheet which encourages delegates 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 using Microsoft Excel enabling the delegate 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.
