38 FOREWORD
39 1) The International Electrotec;hnical Commission (IEC) is a worldwide organization for standardization comprising
40 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
41 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
42 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
43 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
44 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
45 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
46 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
47 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
48 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
49 consensus of opinion on the relevant subjects since each technical committee has representation from all
50 interested IEC National Committees.
51 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
52 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
53 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
54 misinterpretation by any end user.
55 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
56 transparently to the maximum extent possible in their national and regional publications. Any divergence between
57 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
58 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
59 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
60 services carried out by independent certification bodies.
61 6) All users should ensure that they have the latest edition of this publication.
62 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
63 members of its technical committees and IEC National Committees for any personal injury, property damage or
64 other damage of any nature whatsoever, whether direct or indir
