Title Thermocouples - Part 1: EMF specifications and tolerances
Project Number 23893
Abstract/Scope IEC 60584-1:2013 specifies reference functions and tolerances for letter-designated thermocouples (Types R, S, B, J, T, E, K, N, C and A). Temperatures are expressed in degrees Celsius based on the International Temperature Scale of 1990, ITS-90 (symbol t90), and the EMF (symbol E) is in microvolts. The reference functions are polynomials which express the EMF, E in V, as a function of temperature t90 in °C with the thermocouple reference junctions at 0 °C. Values of EMF at intervals of 1 °C are tabulated in Annex A. This third edition cancels and replaces the second edition published in 1995 and constitutes a technical revision. It includes the following changes: - IEC 60584-1:1995 and IEC 60584-2:1982 have been merged; - the standard is now explicitly based on the reference polynomials which express thermocouple EMF as functions of temperature. The tables derived from the polynomials are given in Annex A; - inverse polynomials expressing temperature as functions of EMF are given in Annex B, but inverse tables are not given; - the range of the polynomial relating the EMF of Type K thermocouples is restricted to 1 300 °C; - values of the Seebeck coefficients are given at intervals of 10 °C; - thermoelectric data (EMF and Seebeck coefficients) are given at the fixed points of the ITS-90; - some guidance is given in Annex C regarding the upper temperature limits and environmental conditions of use for each thermocouple type.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn


(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
