Resolution 7 of the 20th CGPM (1995)

Metrology in chemistry

The 20th Conférence Générale des Poids et Mesures,


  • that reliability in the results of quantitative chemical analyses is important for international trade, for the protection of the environment, and for human health and safety,
  • that reliability implies world-wide uniformity and long-term stability and can only be achieved by firmly linking measurements to the Système International d'Unités,
  • that formidable difficulties exist in establishing international traceability for measurements in chemistry,
  • that national metrology laboratories are increasingly involved in establishing such a system,

welcomes the action of the Comité International in creating for this field a Comité Consultatif pour la Quantité de Matière


invites national metrology laboratories, other expert national, regional and international organizations bringing together specialists in measurement in chemistry to collaborate with the Comité International and the new Comité Consultatif in establishing world-wide traceability at the highest level for measurements in chemistry.
