WebSpecialized Fixed Point above °C 4 / 37 1. Introduction The International Temperature Scale of 1990 (ITS-90) defines the temperatures of a number of fixed points: the melting, freezing, and triple points of pure substances [Preston-Thomas 1990]. The fixed points are used as calibration points for standard thermometers, also defined by ITS-90.
