Aims and topics
Aims
The workshop considered measurement uncertainty evaluation for sampling and analysis in the context of ISO/IEC 17025:2017. The workshop was intended for laboratory managers and staff concerned with
- designing and implementing sampling protocols to ensure acceptable levels of uncertainty in results and conclusions
- developing and maintaining field or laboratory procedures for measurement uncertainty evaluation and reporting to meet the requirements of ISO/IEC 17025:2017
- reporting measurement uncertainty in conformity assessment decisions under ISO/IEC 17025:2017
Topics
The workshop discussed
- New provisions in the recently revised Eurachem Guide “Measurement uncertainty arising from sampling”
- Improved methods for evaluating uncertainty from sampling
- Current approaches to the evaluation of measurement uncertainty in analysis
- Limitations in uncertainty evaluation under the ISO Guide to the Expression of Uncertainty in Measurement (GUM)
- New approaches for expressing measurement uncertainty – large uncertainties and asymmetry
- Recent developments in uncertainty evaluation using validation and QC data
- Measurement uncertainty, conformity assessment and decision rules in ISO/IEC 17025:2017
- Measurement uncertainty and regulation
- Software for measurement uncertainty evaluation
- Planning and accreditation of sampling under ISO/IEC 17025:2017
- New directions for international guidance – the future of the GUM
