stamped in 1840, commemorating the law of 4th July 1837, has on
one side “To all times – To all peoples”, and “Unity of the
Measurements” on the other. This states the need that was felt very
early in the world of industrial measurement, the need to collaborate
regardless of political differences and, in addition, to establish and use
a coherent and universal system. If the word “need” is a dominant
recurring theme, it is because metrology is not reserved for isolated,
initiated people in their ivory towers. Each day, it is constantly
resorted to, often unknowingly, for tasks that are regarded as
commonplace. Measuring is closely related to any human, scientific,
industrial or commercial activity. Its role is constantly increasing and
it concerns such vital sectors as energy, health, communications, food,
armament, the security of goods and people, environment, transport,
public works, etc. In order that measuring should have some meaning,
and its results should be unquestionable and might be compared to
those obtained at other times and in other places, each measurement
must be related to a standard by an unbroken chain. It is the role of
metrology to forge the different links of the chain and to make sure it
does a good job.
