80 Part 17: Alias Names
82 FOREWORD
83 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
84 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all
85 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities,
86 IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)
87 and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
88 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
89 and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
90 the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between
91 the two organizations.
92 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
93 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
94 Committees.
95 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
96 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
97 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
98 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
99 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
100 the corresponding national or regional publication shall be clearly indicated in the latter.
101 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
102 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
103 independent certification bodies.
104 6) All users should ensure that they have the latest edition of this publication.
105 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of
106 its technical committees and IEC National Committees for any personal injury, property damage or other damage of any
107 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication,
108 use of, or reliance upon, this IEC Publication or any other IEC Publications.
109 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
110 for the correct application of this publication.
111 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
112 IEC shall not be held responsible for identifying any or all such patent rights.
113 The main task of IEC technical committees is to prepare International Standards. However, a technical
114 committee may propose the publication of a technical report when it has collected data of a different
115 kind from that which i
