Overview

The validity of measurements made have little meaning unless the uncertainty of the test or calibration process is known. Many standards, including ISO/TS 16949 and ISO/IEC 17025, require that the uncertainty of measurement be taken into account when performing measurement activities. This workshop will acquaint delegates with the requirements of ISO/IEC 17025 and particularly the salient principles contained in ISO Guide 98-3 Guide to the expression of Uncertainty in Measurement and other guidance document M3003. Methodologies to calculate uncertainty budgets are defined as well as the basic statistics required. The course provides practical uncertainty exercises and all of the activities are supported with examples of typical uncertainty budgets, which are chosen to cover different fields of measurement.

This one day Measurement Uncertainty training course will provide delegates working in the field of measurement with the knowledge to develop uncertainty budgets to meet the requirements of ISO/IEC 17025 and laboratory accreditation bodies.

Key Topics

  • The importance of uncertainty of measurement
  • Basic concepts: traceability, uncertainty and terminology
  • Impact of uncertainty on results and compliance with specifications
  • Errors, effects and corrections
  • Type A uncertainties and selection of statistical tools
  • Type B uncertainties, identification and use
  • Combined uncertainties
  • Expanded uncertainties and confidence intervals
  • Reporting of uncertainties
  • Sources of uncertainty in different calibration fields
  • Worked examples
  • Attribute Studies
  • Sources of further information

Who Should Attend

  • Quality and Design Engineers
  • Laboratory and Technical Personnel
  • Assessors of Laboratory/Quality Management Systems
  • Assessors of calibration and testing laboratories
  • Quality and Technical Managers

Although not essential, personnel attending this course should have a basic knowledge of maths and statistical techniques. Participants should bring a laptop computer or calculator which has basic statistical functions

Outcomes

By the end of this course, delegates will be able to:

  • Apply the methodologies for calculating uncertainty budgets using practical examples.
  • Develop a structured uncertainty budget, with an awareness of the uncertainty contributions associated with a measurement system and how to evaluate the magnitude of these errors.
  • Utilise the results of uncertainty budgets to determine cost and efficiency improvements in measurement systems.

Dedicated Training

The course includes 10 modules and interactive workshops covering topics such as ‘Reporting of Uncertainties’, ‘Traceability, Accuracy, Linearity, Stability and Uncertainty’ and ‘Quantifying Uncertainty Components’. Our Measurement Uncertainty Training Course is based on the requirements of ISO/IEC 17025. Dedicated training is often more cost effective and convenient for organisations wishing to train several employees. The training can occur at a venue of your choice or online.
