IEC 60751 Ed. 3.0 b – Industrial platinum resistance thermometers and platinum temperature sensors

This International Standard specifies the requirements, in addition to the resistance versus temperature relationship, for both industrial platinum resistance thermometers (later referred to as “thermometers”) and industrial platinum resistance temperature sensors (later referred to as “platinum resistors”) whose electrical resistance is derived from defined functions of
temperature.

Values of temperature in this document are in terms of the International Temperature Scale of
1990, ITS-90. A temperature in the unit °C of this scale is denoted by the symbol t, except in Table A.1 where the full nomenclature t90 /°C is used.
