The values assigned to the temperatures of the boiling point of water and the freezing points of tin and zinc on the International Practical Temperature Scale of 1968 appear to be significantly higher than thermodynamic values. The new measurements, done by Leslie Guildner and Robert Edsinger with a very carefully built gas thermometer at the National Bureau of Standards, may lead to a redefinition of the International Practical Temperature Scale.
