Harmonized Approach to Metrological Traceability of Chemical
measurements are important for almost every aspect of our
life, including health, food, laboratory medicine, environment,
and water and energy resources, as well as science. Chemical
measurements affect the world economy at large and are the
subject of a number of international mutual recognition agreements
and similar arrangements. However, only measurement results
where metrological traceability is clearly established can
be compared, independent from when and where they were obtained.
This projects objective is to develop common concepts
for metrological traceability of measurement results obtained
by measurement procedures (techniques) based on sound measurement
principles and methods in chemistry as well as physics.
common concepts shall be:
to all metrological levels from a basic definition of the
"stated reference" (units or others) through metrological
institutions preparing and distributing metrological tools,
to the field laboratories using metrological tools in their
routine work, and to end-users who should know and be able
to assess the metrological validity of the results obtained
by or reported to them
to all measurement: routine, research, commercial, ad hoc,
understandable to a wider measurement community, including
students, routine analysts, industry, research and scientific
workers, as well as to legislators, accreditation bodies,
and other regulatory institutions
general in nature, thus enabling new emerging fields and
techniques to be easily incorporated
interdisciplinary, thus ensuring common understanding, encouraging
cross-fertilization (for instance, between chemistry and
physics), and at the same time clearly presenting and addressing
specifics of various measurement areas
document, preferably in the form of an interorganizational
harmonized protocol, will constitute the basic outcome of
the project. Premises to this project are detailed in the
Web pages at the address below and in CI (Vol.
25, No. 2 March-April 2003, p 17).
