Chapter 4

The Environment of Measuring

This chapter might be summed up as:
– “It is not because a measuring instrument is new that it is good.”
– “It is not enough to use good equipment to make good
measurements.”
The result of a measurement is the conclusion of a process which
is comprised of:
– the implementation of a method;
– the utilization of measuring equipment;
– the intervention of operators;
– a physical environment (temperature, etc.);
– a measurement procedure.
All these elements have an influence on the result. Thus, it is
essential to make a few general points:
– depending on the expected accuracy, the place where the
instrument is used is analyzed in order to reveal any possible
significant interactions;
– so as to make sure of the quality of the measurement results, the
qualification of the operators has to be checked and ascertained. As in
any field, it is important to ensure the suitability of both the manpower
and the function;
– it can be difficult to guarantee the quality of these activities
without a good document which describes, among other items, the
measurement procedures.
