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