Course Introduction

Measurements are always made for a purpose – may be to answer a specific question or to help solve a problem. Whenever a measurement is made there will always be some uncertainty about the result due to unavoidable errors in the measurement process. The validity of absolute measurements made have little meaning unless the uncertainty of the test or calibration process is known. Many standards, including ISO/IEC 17025 and ISO/TS 16949, require that the uncertainty of measurement be taken into account when performing test and calibration activities.

Knowledge of the uncertainty associated with measurement results allows a judgment to be made as to whether the data are likely to be ‘fit for purpose’. If comparisons of results are being made, The evaluation of the uncertainty associated with measurement results is a requirement for testing laboratories accredited to ISO/IEC 17025.

Industrial Training Objectives

This two-day workshop will acquaint delegates with the requirements of ISO/IEC 17025, particularly the salient principles in the expression of Uncertainty in Measurement, which defines methodologies to calculate uncertainty budgets, as well as covering the basic statistics required. This course provides a practical approach to evaluating uncertainty in testing laboratories which is in line with the ISO principles for uncertainty estimation and current accreditation requirements. The course assumes no prior knowledge of uncertainty evaluation.
