Aims and topics

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
