ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— IEC Electropedia: available at https://www.electropedia.org/
— ISO Online browsing platform: available at https://www.iso.org/obp
3.1
referee method
stoichiometric method or a method calibrated against pure metals or stoichiometric compounds, which
is to be used for certification analysis or in case of arbitration
Note 1 to entry Due to lack of accuracy or to a low number of laboratories having participated to the related
validation tests, some stoichiometric methods or methods calibrated against pure metals or stoichiometric
compounds cannot be taken as "referee methods". They are published as CEN/TRs.
3.2
routine method
method calibrated against reference materials or certified reference materials, or against standard
solutions commercially available, which is widely used for control purposes (day to day analysis)
