The physicochemical quantitty reproducer by these standards is electrolytic conductivity ĸ. It is expressed in the SI units: S/m. The certified electrolytic conductivity is traceable to the DFM's (Danish Fundamental Metrology) and GUM's (Central Office of Measures in Poland) standards. Validity of the electrolytic conductivity standards is twelve months. The CRM standards are disigned for the determination of the conductivity cell constant for the measurement of the electrolytic conductivity.
