Terms of reference

  • To carry out Key Comparisons, and where necessary pilot studies, to critically evaluate and benchmark NMI/DI claimed competences for measurement standards and capabilities for the amount of substance fraction or mass fraction measurements of the elements; cations and anions; inorganic compounds; and organo‐metallic compounds. Matrices to be covered include: pure materials, calibration solutions and complex samples such as those used for matrix reference materials.
  • To assist in identifying and establishing inter‐laboratory work and pilot studies for the purpose of jointly developing new methodology and investigating issues associated with SI traceability.
