86 FOREWORD
87 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
88 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
89 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
90 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
91 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
92 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
93 in the subject dealt with may participate in this preparatory work. International, governmental and non-
94 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
95 with the International Organization for Standardization (ISO) in accordance with conditions determined by
96 agreement between the two organizations.
97 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
98 consensus of opinion on the relevant subjects since each technical committee has representation from all
99 interested IEC National Committees.
100 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
101 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
102 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
103 misinterpretation by any end user.
104 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
105 transparently to the maximum extent possible in their national and regional publications. Any divergence
106 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
107 the latter.
108 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
109 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
110 services carried out by independent certification bodies.
111 6) All users should ensure that they have the latest edition of this publication.
112 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual
