100 FOREWORD
101 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
102 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
103 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
104 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
105 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
106 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
107 in the subject dealt with can participate in this preparatory work. International, governmental and non-
108 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
109 with the International Organization for Standardization (ISO) in accordance with conditions determined by
110 agreement between the two organizations.
111 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
112 consensus of opinion on the relevant subjects since each technical committee has representation from all
113 interested IEC National Committees.
114 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
115 Committees in th
