Quality Assurance Challenges of Measurements from Field to Laboratory with a Focus on ISO/IEC 17025:2017 Requirements

The workshop was kindly hosted by the Georgian Laboratory Association (GeLab), in conjunction with the 2022 Eurachem General Assembly.

The workshop was run online over three days. Over 120 participants attended, from 33 countries.The workshop addressed current practices, challenges, and future recommendations on quality assurance of physochemical and microbiological measurement methods and their validation, including sampling-related issues.

The separate pages below give details of the workshop arrangements and programme, and available presentation material can be found on the Presentations and Posters tabs below.

Workshop Aims

This workshop was intended to be of direct relevance to anyone who is focused on the quality of analytical measurements and the reliability of decisions based on test results in accordance with ISO/IEC17025 requirements, taking into account the influence of factors that exist outside the laboratory environment. Such factors are mainly related to sampling or on-site measurements, and occur in the daily life of laboratories operating in many different fields such as food and beverages, health, environment, forensics, pharmaceuticals, etc.


Note: Times are provisional, and in Central European Summer Time. Check the Event website for final schedule.
