99 FOREWORD
100 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
101 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
102 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
103 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
104 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
105 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
106 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
107 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
108 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
109 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an internati
