106 FOREWORD
107 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all
108 national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-
109 operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to
110 other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available
111 Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical
112 committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work.
113 International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation.
114 IEC collaborates closely with the International Organization for Standardization (ISO) in acc
