Scope

This part of IEC 60584 specifies the reference functions and tolerances associated with letter-designated thermoelectric couples (Types R, S, B, J, T, E, K, N, C and A). Temperatures are expressed in degrees Celsius according to the 1990 International Temperature Scale, EIT-90 (symbol t90) and the EMF (symbol E), in microvolts. The reference functions are polynomials which express the EMF, E in pico V, as a function of the temperature t90 in oC, the reference junctions of the thermoelectric couples being placed at 0 oC. Annex A presents, in tabular form, the values of the EMF every 1 oC. For ease of calculation
