23、TROTECHNICAL COMMISSION _ SAFETY PROCEDURES FOR REDUCTION OF RISK OUTSIDE A STRUCTURE 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

24、 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 Gu

25、ides (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 IE

26、C 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

27、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

28、. 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 under

29、take 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 atte

30、station 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

31、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 direct

32、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 indispensable

33、 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. The main task of IEC technical committees

34、 is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC/TR 62713, which is a technic

35、al report, has been prepared by IEC technical committee 81: Lightning protection. The text of this technical report is based on the following documents: Enquiry draft Report on voting 81/427/DTR 81/429/RVC Full information on the voting for the approval of this technical report can be found in the r

36、eport on voting indicated in the above table. 4 TR 62713 IEC:2013 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “h

37、ttp:/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. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are consider

38、ed to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. TR 62713 IEC:2013 5 INTRODUCTION IEC/TR 62713, which is a technical report, is informative, with the purpose of giving the lay person, i. e. a non-specialist in lightning

39、 protection and a non-medically trained person, appropriate action to reduce risk from lightning to people outside fixed structures, i. e. in a variety of everyday outdoor activities, including immediate action to take in the event of a person being injured by lightning. Part of these precautions in

40、cludes taking shelter in either a lightning protected structure or an unprotected structure. Any action in the long term to ensure that such structures are suitably protected should be designed by a lightning protection specialist based on the requirements of the appropriate parts of IEC 62305 as li

41、sted in the normative references of this report. It is not the purpose of this report to quantify the risk reduction achieved by taking the precautions suggested in it. 6 TR 62713 IEC:2013 SAFETY PROCEDURES FOR REDUCTION OF RISK OUTSIDE A STRUCTURE 1 Scope This technical report introduces lightning

42、to the layman, noting the right action in the presence of thunderstorms, as well as protective measures against lightning. It also contributes to the prevention of lightning injuries and damages. It should be noted that so far there are no means to avoid lightning. However, by following some element

43、ary rules, people can be protected against its deleterious effects. 2 Normative references None. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 aphasia inability to express thought in words or inability to understand thought as expressed in
