適用范圍：This International Standard specifies the equations and reference tables relating temperatureto EMF (electro-motive force) for Gold versus Platinum and Platinum versus Palladiumthermocouples. For information and convenience of use it also provides the approximateequations for temperature as functions of EMF~The tables and equations in this standard are intended for use with thermocouples made fromelements of purity not less than 99.999 % for Platinum and Gold and of 99.99 % forPalladium, by weight.Tolerances on initial values of EMF versus temperature have not been established for thethermocouples in this standard. Where required, these tolerances should be agreed betweenthe wire manufacturer and the user.Temperatures in this standard are based on the International Temperature Scale of 1990(ITS-90). They are expressed in degrees Celsius, symbol t90. Values of EMF, symbol E/~V,are given in microvolts.This standard does not cover extension or compensating wires for use with the pure-elementthermocouples. The questions of their use shall be agreed between the manufacturer and theuser.
