72 POLYMERIC HV INSULATORS FOR INDOOR AND OUTDOOR USE -
73 GENERAL DEFINITIONS, TEST METHODS AND ACCEPTANCE CRITERIA
76 FOREWORD
77 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
78 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
79 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
80 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
81 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
82 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
83 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
84 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
85 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
86 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
87 consensus of opinion on the relevant subjects since each technical committee has repres entation from all
88 interested IEC National Committees.
89 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
90 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
91 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
92 misinterpretation by any end user.
93 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
94 transparently to the maximum extent possible in their national and regional publications. Any divergence between
95 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
96 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
97 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
98 services carried out by independent certification bodies.
99 6) All users should ensure that they have the latest edition of this publication.
100 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
101 members of its technical committees and IEC National Committees for any personal injury, property damage or
102 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
103 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
104 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
105 indispensable for the correct application of this publication.
106 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
107 rights. IEC shall not be held responsible for identifying any or all such patent rights.
108 International Standard IEC 62217 has been prepared by IEC technical committee 36: Insulators.
109 This third edition of the standard cancels and replaces the second edition, published in 2012.
110 It constitutes its technical revision and introduces the fol
