28、HNICAL COMMISSION _ MINERAL INSULATED METAL-SHEATHED THERMOCOUPLE CABLES AND THERMOCOUPLES 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

29、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) a

30、nd 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 th

31、e 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

32、 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 s

33、ense. 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 u

34、ndertake 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

35、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 edit

36、ion of this publication. 7) 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 dir

37、ect or indirect, or for costs (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 indispens

38、able for the correct application 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 61515 has

39、been prepared by subcommittee 65B: Measurement and control devices, of IEC technical committee 65: Industrial-process measurement, control and automation. This second edition cancels and replaces the first edition published in 1995. This edition constitutes a technical revision. This edition include

40、s the following significant technical changes with respect to the previous edition: a) Duplex and triplex are standardized. b) Specification of insulation resistance is revised so that the user can choose the best product to fit for the purpose. c) “Table 2 Recommended maximum operating temperatures

41、” in the previous version is expanded significantly including newly developed sheath material and it is moved to Annex C. d) Test items and their methods are expanded and a guide table (Table 4) is added for userfriendliness.

42、ed on the following documents: FDIS Report on voting 65B/1034/FDIS 65B/1038/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The

43、 committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised

44、edition, or amended. BS EN 61515:2016 6 IEC 61515:2016 IEC 2016 INTRODUCTION This new edition of IEC 61515 reflects recent developments in production technology, sheath materials and insulation materials. It aims to be a flexible standard allowing suppliers to provide fit-for-purpose products at an

45、acceptable cost. It includes informative guidance to help users choose the products that meet their needs. Annex A gives alternative adjacent conductor configurations for duplex and triplex MIMS thermocouple cables and thermocouples. Annex B gives recommendations to suppliers with respect to insulat

46、ion composition. Annex C gives guidelines to users with regard to temperature limits of operation. BS EN 61515:2016IEC 61515:2016 IEC 2016 7 MINERAL INSULATED METAL-SHEATHED THERMOCOUPLE CABLES AND THERMOCOUPLES 1 Scope This International Standard establishes the requirements for simplex, duplex and

47、 triplex mineral-insulated metal-sheathed thermocouple cables and thermocouples, which are intended for use in general industrial applications. The abbreviation MIMS (for “mineral-insulated metal-sheathed”) will be used hereafter. It covers thermocouple cables and thermocouples with only base-metal

48、conductors of Types T, J, E, K and N. The specifications in this standard apply to new thermocouple cables and thermocouple units as delivered to the user. They do not apply to the product after use. External seals, terminations, connections and other accessories are not within the scope of this Int

49、ernational Standard. This standard does not apply to precious metal thermocouple cables and thermocouples. The special requirements for nuclear primary loop applications are dealt with in the other standards. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
