Use of the C-NPU Concept System for Properties in Toxicology
of this project is to work out properties and units for global use of
the C-NPU (Committee on Nomenclature, Properties and Units) concept
system and syntactic rules for properties in toxicology. The C-NPU,
maintained as a joint IFCC- IUPAC activity for two decades, has as its
main task to promote and maintain scientifically and conceptually sound
ways of expressing the outcome of measurements and other examinations
in laboratory medicine. The NPU coding scheme and vocabulary, based
on the SI system, concepts theory, and high-level international standards,
is the main outcome and should be the cornerstone for expressing measurements
within international communication standards.
the first meeting (3-4 August 2002), a first draft by J. H. Duffus was
discussed that involved properties in toxicology based on the general
structure elaborated by C-NPU. The C-NPU concept system was proven to
be appropriate for that purpose as demonstrated by a large number of
typical examples. For the next meeting (5-6 December 2002), a draft
comprehensive list will be prepared for discussion and after corrections
it will be distributed for comments among appropriate organizations
and individual specialists.
