22、IONS Part 10: Particular requirements for electrical resistance trace heating systems for industrial and commercial applications FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC Na

23、tional 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, Pub

24、licly 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-gover

25、nmental 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 o

26、n 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 accepte

27、d 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

28、 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 latte

29、r. 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

30、 ensure that they have the latest edition 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

31、 of any nature whatsoever, whether direct 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 th

32、e referenced publications is indispensable 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.

33、 International Standard IEC 60519-10 has been prepared by IEC technical committee 27: Industrial electroheating and electromagnetic processing. This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision. This edition includes the follo

34、wing significant technical changes with respect to the previous edition: The structure has been amended and adjusted to IEC 60519-1:2010; References to IEC 62395-11and IEC 62395-22have been completed. 1 Second edition to be published. 2 First edition (replacing IEC/TS 62395-2:2008) to be published.

35、4 60519-10 IEC:2013 The text of this standard is based on the following documents: CDV Report on voting 27/853/CDV 27/873/RVC 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 accor

36、dance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 60519 series, published under the general title Safety in electroheating installations, can be found on the IEC website. The clauses of parts of the IEC 60519 series (hereinafter called Particular requirements) supplement or m

37、odify the corresponding clauses of IEC 60519-1:2010 (General requirements hereinafter called Part 1). This part of IEC 60519 is to be read in conjunction with Part 1. It supplements or modifies the corresponding clauses of Part 1. Where the text indicates an “addition“ to or a “replacement“ of the r

38、elevant provision of Part 1, these changes are made to the relevant text of Part 1. Where no change is necessary, the words “This clause of Part 1 is applicable“ are used. When a particular subclause of Part 1 is not mentioned in this part, that subclause applies as far as is reasonable. Additional

39、specific provisions to those in Part 1, given as individual clauses or subclauses, are numbered starting from 101. NOTE The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless notes are in a new subclause or

40、 involve notes in Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; additional annexes are lettered AA, BB, etc. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site

41、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 edition, or amended. 60519-10 IEC:2013 5 INTRODUCTION It is the objective of this standard that, when in accordance with the standard, el

42、ectrical trace heating systems operate safely under their normal defined conditions of use, by a) employing heaters of the appropriate construction and meeting the test criteria detailed in IEC 62395-1; b) operating at safe temperatures when designed, installed, and maintained in accordance with IEC

43、 62395-2; c) having at least the minimum levels of overcurrent and ground-fault protection, and an evenly distributed electrically conductive metallic braid, sheath or other equivalent electrically conductive material, as specified in IEC 62395-1 and IEC 62395-2. 6 60519-10 IEC:2013 SAFETY IN ELECTR

44、OHEATING INSTALLATIONS Part 10: Particular requirements for electrical resistance trace heating systems for industrial and commercial applications 1 Scope and object This clause of Part 1 is replaced by the following. Replacement: This part of IEC 60519 provides safety requirements for electrical re

45、sistance trace heating systems used in industrial and commercial applications for piping, vessels, roofs, concrete slab heating and other similar applications. This standard pertains to trace heating systems that may comprise either factory fabricated or field (work-site) assembled units, and which

46、may be series heater cables, parallel heater cables, heater pads or heater panels that have been assembled and/or terminated in accordance with manufacturers instructions. Typical applications include but are not limited to the freeze protection of pipes, tanks and vessels, including fire water syst

47、ems; maintaining required temperatures of equipment, including pipes, tanks and vessels; earth thermal storage; hot water temperature maintenance; snow melting of surfaces; de-icing of roofs and gutters. This standard does not include or provide for any requirements in potentially explosive atmosphe

48、res. This part of IEC 60519 does not cover induction, impedance or skin effect heating. NOTE Specific requirements and test criteria for electrical resistance trace heating systems and design, installation, and maintenance requirements for these systems are detailed in IEC 62395-1 and IEC 62395-2. T

49、his standard provides general safety requirements for the installation, operation, maintenance and repair of systems and individual circuits and for trace heating systems designs. These safety considerations concern the protection of persons and the environment against dangers of electrical origin and also against certain dangers of non-electrical origin, common to all types of equipment and installations.
