This standard specifies the requirements and temperature/resistance relationship for
industrial platinum resistance temperature sensors later referred to as "platinum resistors" or
"resistors" and industrial platinum resistance thermometers later referred to as
"thermometers" whose electrical resistance is a defined function of temperature.
Values of temperature in this standard are in terms of the International Temperature Scale of
1990, ITS-90. Temperatures in degrees Celsius are denoted by the symbol t, except in
Table 1 where the full nomenclature t<(down)90>/℃is used.
The standard covers resistors or thermometers for all or part of the temperature range
-200 ℃ to +850 ℃ with different tolerance classes, which may cover restricted temperature
ranges.
For temperature/resistance relationships with uncertainties <0,1 ℃, which are possible only
for resistors or thermometers with exceptionally high stability and individual calibration, a
more complex interpolation equation than is presented in this standard may be necessary.
The specification of such equations is outside the scope of this standard.
