Thermocouples - Part 1: Reference tables
Establishes a set of reference tables for the seven most commonly used types of commercially available thermocouples, giving both electromotive force as a function of temperature and temperature as a function of electromotive force. Gives polynominal expressions from which the reference values can be computed. The reference tables are based on fundamental research and are consistent with the current edition of the International Practical Temperature Scale (1968) and are not limited to applications in the field of industrial process measurement and control.

Couples thermoélectriques - Partie 1: Tables de référence
Offre un ensemble de tables de référence consacrées aux sept types les plus courants de thermocouples commerciaux avec la force électromotrice en fonction de la température et vice versa. Indique les polynômes servant à calculer les valeurs de référence. Etablies d'après des recherches fondamentales, ces tables de référence sont conformes à l'édition en vigueur de l'échelle internationale pratique des températures de 1968; leur application ne se limite pas au domaine des mesures et des commandes de processus industriels.

584-1 © IEC:1995– 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSIONTHERMOCOUPLES —Part 1: Reference tablesFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational cooperation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC published International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non—governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters, prepared by technical committees on whichall the National Committees having a special interest therein are represented, express, as nearly as possible, aninternational consensus of opinion on the subjects dealt with.3)They have the form of recommendations for international use published in the form of standards, technicalreports or guides and they are accepted by the National Committees in that sense.4)In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standards and the corresponding national or regional standard shall be clearlyindicated in the latter.International Standard IEC 584-1 has been prepared by sub-committee 65B: Devices, of IECtechnical committee 65: Industrial-process measurement and control.This second edition cancels and replaces the first edition and amendment published in 1977and 1989 respectively and constitutes a technical revision.The text of this standard is based on the following documents:DISReport on voting

584-1 © I EC:1995– 7 –INTRODUCTIONThis International Standard is based upon the International Temperature Scale of 1990 (ITS-90). Temperatures are expressed in degrees Celsius (symbol t90), the e.m.f. (symbol E) inmicrovolts. The tables it contains have been updated to take into account the change from theInternational Practical Temperature Scale of 1968 (IPTS-68).The new tables for types S and R are based upon experimental work conducted by:IMGCof Italy*KRISSof South Korea*NISTof USANPLof United KingdomNRLMof Japan*SIPAIof P.R. of China*VNIIMof Russia*VSLof Netherlands*and are not dependent upon any particular values of the secondary reference points. However,if it is desired to calibrate a thermocouple using some of these secondary reference points,then the temperatures assigned to them in the latest tabulation published in Metrologia shouldbe used.The tables for types B, J, T, E, K and N have been mathematically converted from the tablescontained in the first edition of IEC 584-1. The calculations have been made by NIST of USAand have been described in NIST Monograph 175.* Type S only.SIST EN 60584-1:1998
584-1 ©IEC:1995– 9 –THERMOCOUPLES —Part 1: Reference tables1 ScopeThis International Standard provides thermocouple reference tables for use in convertingthermocouple voltages into their equivalent measured temperatures and vice versa.The polynomial equations from which the tables are derived have been included in annex A,hence no tolerances are given. The reference tables (E = f(t)) have been derived from therespective reference functions and the inverse tables (t = f(E)) from the respective inversefunctions.2 Definitions2.1 thermoelectric (Seebeck) effect: The production of an electromotive force (E) due tothe difference of temperature between two junctions of different metals or alloys forming part ofthe same circuit.2.2 thermocouple: Pair of conductors of dissimilar materials joined at one end and formingpart of an arrangement using the thermoelectric effect for temperature measurement.2.3 measuring junction: That junction which is subjected to the temperature to bemeasured.2.4 reference junction: That junction of the thermocouple which is at a known (reference)temperature to which the measuring temperature is compared.2.5 reference temperature: For the tables of this document, the reference temperatureis 0 °C.3 Thermocouple type letter designationsThe following letter designations are established for the thermocouple wire combinations:Letter Thermocouple typeRPlatinum-13 % rhodium/platinumSPlatinum-10 % rhodium/platinumBPlatinum-30 % rhodium/platinum-6 % rhodiumJIron/copper-nickelTCopper/copper-nickelENickel-chromium/copper-nickelKNickel-chromium/nickel-aluminiumNNickel-chromium-silicon/nickel-siliconWhen identifying noble or base metal thermocouples by their nominal alloy combinations, thepositive leg shall be listed first.SIST EN 60584-1:1998
