Foreword
The text of document 65B/873/FDIS, future edition 3 of IEC 60584-1, prepared by SC 65B
"Measurement and control devices" of IEC/TC 65 "Industrial-process measurement, control and
automation" was submitted to the IEC-CENELEC parallel vote and approved by CENELEC as
The following dates are fixed:
• latest date by which the document has to be (dop) 2014-07-02
implemented at national level by
publication of an identical national
standard or by endorsement
(dow) 2016-10-02
• latest date by which the national
standards conflicting with the
document have to be withdrawn
This document supersedes EN 60584-1:1995 and EN 60584-2:1993.

EN 60584-1:1995 and EN 60584-2:1993:
a) EN 60584-1:1995 and EN 60584-2:1993 have been merged;
b) 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;
c) inverse polynomials expressing temperature as functions of EMF are given in Annex B, but inverse
tables are not given;
d) the range of the polynomial relating the EMF of Type K thermocouples is restricted to 1 300 °C;
e) values of the Seebeck coefficients are given at intervals of 10 °C;
f) thermoelectric data (EMF and Seebeck coefficients) are given at the fixed points of the ITS-90;
g) some guidance is given in Annex C regarding the upper temperature limits and environmental
conditions of use for each thermocouple type.

Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.
Endorsement notice

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach
