BS EN 62460:2008EN 62460:2008 - 2 - Foreword The text of document 65B/665/FDIS, future edition 1 of IEC 62460, prepared by SC 65B, Devices any IEC National Committee interested in the subject dealt with may participate in this preparatory work
12、. 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)
13、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 recommenda
14、tions 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
15、 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 publicat
16、ion shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7)
17、No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for cost
18、s (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct applica
19、tion of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62460 has been prepared by subcommitte
20、e 65B: Devices and process analysis, of IEC technical committee 65: Industrial-process measurement, control and automation. The text of this standard is based on the following documents: FDIS Report on voting 65B/665/FDIS 65B/684/RVDFull information on the voting for the approval of this standard ca

At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. BS EN 62460:200862460 IEC:2008 5 TEMPERATURE ELECTROMOTIVE FORCE (EMF) TABLES FOR
23、PURE-ELEMENT THERMOCOUPLE COMBINATIONS 1 Scope This International Standard specifies the equations and reference tables relating temperature to EMF (electro-motive force) for Gold versus Platinum and Platinum versus Palladium thermocouples. For information and convenience of use it also provides the
24、 approximate equations for temperature as functions of EMF. The tables and equations in this standard are intended for use with thermocouples made from elements of purity not less than 99.999 % for Platinum and Gold and of 99.99 % for Palladium, by weight. Tolerances on initial values of EMF versus
25、temperature have not been established for the thermocouples in this standard. Where required, these tolerances should be agreed between the 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 C
26、elsius, 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-element thermocouples. The questions of their use shall be agreed between the manufacturer and the user. 2 Normative references The following refe
27、renced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60584-1, Thermocouples Reference tables 3 Terms and definitions
28、 For the purposes of this document, the terms and definitions given in IEC 60584-1 apply, as well as the following. 3.1 thermocouple types the following thermocouple wire types are covered by this standard: Gold versus Platinum (Au/Pt or Gold/Platinum) Platinum versus Palladium (Pt/Pd or Platinum/Pa
29、lladium) Following international convention, as in IEC 60584-1, when identifying thermocouples the positive element/wire is given first. BS EN 62460:2008 6 62460 IEC:2008 3.2 thermoelectric values at the ITS-90 fixed points values are given for the defining triple points (TP), melting points (MP) an
30、d freezing points (FP) in the temperature range of the corresponding tables. The Seebeck coefficient S is the first derivative of the EMF with respect to temperature. 4 Information on tables and equations The following tables are included in this standard: Gold versus Platinum: EMF at intervals of 1
31、 C Gold versus Platinum: temperatures at intervals of 10V Gold versus Platinum: thermoelectric values at the fixed points of the ITS-90 Platinum versus Palladium: EMF at intervals of 1 C Platinum versus Palladium: temperatures at intervals of 10V Platinum versus Palladium: thermoelectric values at t
32、he fixed points of the ITS-90 For the tables in this document, the reference temperature is 0 C. The definitive equations of EMF, E/V, as functions of temperature, t90/C, which are used to generate the tables, are given in Annex A for Gold/Platinum thermocouples and Annex B for Platinum/Palladium th
33、ermocouples. For information and convenience in use, approximate equations are also given, expressing t90/C as functions of E/V for the respective thermocouples within the stated error limits.
