30、ardization comprising all national electrotechnical committees (IEC National 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 Int
31、ernational Standards, Technical Specifications, Technical Reports, Publicly 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 participa
32、te in this preparatory work. 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 betwee
33、n the two organizations. 2) 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
34、 have the form of recommendations 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
35、misinterpretation by any end 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 n
36、ational or regional publication shall be clearly indicated in the latter. 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 servic
37、es carried out by independent certification bodies. 6) All users should 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 Natio
38、nal Committees for any personal injury, property damage or other damage 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
39、 drawn to the Normative references cited in this publication. Use of the 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
40、 not be held responsible for identifying any or all such patent rights. International Standard IEC 60855-1 has been prepared by technical committee 78: Live working. This second edition cancels and replaces the first edition published in 2009. This edition constitutes a technical revision. This edit
41、ion includes the following significant technical changes with respect to the previous edition: reintroduction of specific diameters of foam-filled tubes and solid rods of circular cross- section with its tolerances; reintroduction of the dielectric tests before and after exposure to humidity, as inc
42、luded in IEC 60855-1:2009; specification of an alternative test (after exposure to immersion) in case of foam-filled tubes and solid rods having completed the production phase; review of phase angle maximum specified values; IEC 60855-1:2016 IEC 2016 5 review of the wet test procedure and the improv
43、ement of the associated test arrangement. The text of this standard is based on the following documents: FDIS Report on voting 78/1147/FDIS 78/1156/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
44、 has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 60855 series, published under the general title Live working Insulating foam-filled tubes and solid rods, can be found on the IEC website. Terms defined in Clause 3 are given in italic print throughou
45、t this standard. The 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, re
46、placed by a revised edition, or amended. 6 IEC 60855-1:2016 IEC 2016 INTRODUCTION This part of IEC 60855 has been prepared in accordance with the requirements of IEC 61477. The product covered by this part of IEC 60855 may have an impact on the environment during some or all stages of its life cycle
47、. These impacts can range from slight to significant, be short-term or long-term, and occur at the global, regional or local level. This part of IEC 60855 does not include requirements and test provisions for the manufacturers of the product, or recommendations to the users of the product for enviro
48、nmental improvement. However, all parties intervening in its design, manufacture, packaging, distribution, use, maintenance, repair, reuse, recovery and disposal are invited to take account of environmental considerations. Technical committee 78 is considering the preparation of IEC 60855-2, which w
49、ould cover foam-filled tubes and solid rods of cross-section other than circular.
