metrology is played by the countries with a larger GNP or possessing
a larger size of metrology institute; they play the largest part in the
projects. The number of projects is a proof of the success of
EUROMET in terms of European cooperation, and some countries
have taken advantage of their participation in EUROMET to develop
their own metrological infrastructure. The spheres that give rise to the
greatest number of projects are electricity, mass and length;
time/frequency, acoustics and flowmetry give rise to the fewest. The
spheres which have the highest number of projects are those that
arouse a high interest, or are developing. There is often a collaboration
outside EUROMET for those whose number of projects may seem
low.
Likewise, the number of projects are not the same within the
categories of cooperation. The realization of common surveys is the
type of collaboration that has the greatest attraction, which shows that
metrologists are determined to pool their work. Interlaboratory
comparisons come second because they are used to demonstrate the
equivalence of standard realizations; they also make possible the
gathering of information about traceability in Europe for the use of
accreditation organizations.
EUROMET remains closely linked to many European and
international organizations. Among them, EA (European Cooperation
for Accreditation), whose technical support is EUROMET, must be
mentioned; so must WELMEC, EUROMET’s twin for legal
metrology. EUROMET also collaborates with such organizations as
EURACHEM; they have developed a common technical domain or
sphere of activity, called the “amount of substance”, now called
chemical metrology, and it is related to physicochemical analyses and
measurements.
