84 General Requirements and Architecture
87 FOREWORD
88 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
89 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co -operation on all
90 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities ,
91 IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)
92 and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
93 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
94 and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
95 the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between
96 the two organizations.
97 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
98 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
99 Committees.
100 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
101 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
102 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
103 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
104 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
105 the corresponding national or regional publication shall be clearly indicated in the latter.
106 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment
107 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
108 independent certification bodies.
109 6) All users should ensure that they have t
