Constructing an interpolation formula for primary-standard and working-standard high-temperature platinum resistance thermometers

Recommendations are made on deviation formulas for the temperature ranges 420–960 and 420–1064° C constructed from three and four reference points for primary-standard and substandard high-temperature platinum resistance thermometers.Translated from Izmeritel'naya Tekhnika, No. 8, pp. 40–42, August, 1993.
