Objective:
To develop a strategy for achieving the IUPAC consolidated approach
to metrological traceability of measurement results in chemistry. To
make arrangements that this approach becomes available for other scientific/measurement
communities where metrological traceability is important but not well
developed/defined yet.
Description:
Traceability as currently defined is a "property of the result
of a measurement or the value of a standard whereby it can be related
to stated references, usually national or international standards, through
an unbroken chain of comparisons all having stated uncertainties".
(International Vocabulary of Basic and General Terms in Metrology, ISO,
Geneva, 1993)
Traceable measurement results with their associated measurement uncertainty,
form the most solid basis for comparability of results at national or
international level.
For many years IUPAC has been active in the area of metrology and standardization,
including traceability of measurement results (clinical chemistry, analytical
chemistry, environment & food, etc.). However, covering different
scientific and measurement fields, different approaches to metrological
traceability have been developed and a consolidated IUPAC approach is
still missing. In addition, there is a fast growing number of fields
where metrological traceability is important but has not yet been properly
tackled, e.g.,GMO and some environmental parameters (pollutants). The
needed work regarding harmonization of approaches related to metrological
traceability is therefore:
- to prepare and promote an IUPAC approach to traceability
- to offer and agree on this approach with other scientific communities,
organizations, groups, etc., dealing with chemical measurements.
