AbstractSince its inception in 1927, the International Temperature Scale has been updated at approximately 20-year intervals to meet the needs of the time: the selection of fixed points and their assigned temperatures have changed, defining instruments have been added and deleted, and the equations have also changed, particularly for the temperature range defined by the platinum resistance thermometer. After presenting the historical development of the PRT-portion of the ITS, a proposal is made to update the ITS-90 in order to achieve closer accord with thermodynamic temperature.
