This guide has been produced by a joint EURACHEM/CITAC Measurement Uncertainty Working Group.
The
first edition of the EURACHEM Guide for “Quantifying Uncertainty in
Analytical Measurement” was published in 1995 based on the ISO "Guide to
the Expression of Uncertainty in Measurement". The second edition was
prepared in collaboration with CITAC in 2000 in the light of practical
experience of uncertainty estimation in chemistry laboratories and the
even greater awareness of the need to introduce formal quality assurance
procedures by laboratories. The second edition stressed that the
procedures introduced by a laboratory to estimate its measurement
uncertainty should be integrated with existing quality assurance
measures, since these measures frequently provide much of the
information required to evaluate the measurement uncertainty.
This third edition retains the features of the second edition and adds information based on developments in uncertainty estimation and use since 2000. The additional material provides:

- Improved guidance on the expression of uncertainty near zero;
- New guidance on the use of Monte Carlo methods for uncertainty evaluation;
- Improved guidance on the use of proficiency testing data:
- Improved guidance on the assessment of compliance of results with measurement uncertainty.

What interesting information. I have been looking for details on ISO 17025 when I came across your post. I found it very awesome to read, thanks so much for sharing.
