Eurachem’s 25th anniversary: two members’ perspective
- 142 Downloads
Eurachem was founded 25 years ago. Its prime aim, as was set out in the Memorandum of Understanding (MoU) signed by its members, was to help establish a system of international traceability for chemical analysis. At that time, there was little international activity in this topic or in the broader field that could be classified as Metrology in Chemistry (MiC); in fact, the concept “Metrology in Chemistry” was hardly in use. The “Guide to the Expression of Uncertainty in Measurement” (GUM)  had not yet been published, but there had been a lot of activities on the evaluation of uncertainty in the higher echelons of physical measurements following the publication of recommendations of the International Bureau of Weights and Measures (BIPM) working party on “Expression of Measurement Uncertainties” in 1980. This way of evaluating and reporting uncertainty had also percolated to other areas of physical measurement but had attracted little or no attention from analytical chemists. As a...
