95 FOREWORD
96 1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
97 all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
98 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
99 this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
100 entrusted to technical committees; any IEC National Committee interested in the subject dealt with may
101 participate in this preparatory work. International, governmental and non-governmental organizations liaising with
102 the IEC also participate in this preparation. The IEC collaborates closely with the International Organization for
103 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
104 2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an
105 international consensus of opinion on the relevant subjects since each technical committee has representation
106 from all interested National Committees.
107 3) The documents produced have the form of recommendations for international use an
