  • The Bundesanstalt für Materialforschung und -Prüfung (BAM) identified a need for an updated statistical solution.

Purpose of the Study:

  • To introduce eCerto, a novel statistical tool for reference material characterization.
  • To ensure eCerto's comparability with established methods like SoftCRM.
  • To highlight eCerto's user-friendly interface from data collection to reporting.

Main Methods:

  • Development of eCerto using the R software environment.
  • Implementation of statistical analysis for collaborative expert laboratory studies.
  • Comparison of eCerto's performance and features against SoftCRM.

Main Results:

  • eCerto provides a comprehensive platform for evaluating measurement data for reference materials.
  • The tool facilitates flexible outlier analysis while maintaining data integrity and transparent documentation.
  • Comparisons demonstrate eCerto's alignment with established certification strategies.

Conclusions:

  • eCerto is a valuable, user-friendly statistical tool for reference material producers and users.
  • The software meets modern requirements for data processing, documentation, and reporting in metrology.
  • BAM will maintain eCerto, ensuring its continued relevance for emerging fields in reference material activity.
