11 FOREWORD
12 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
13 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
14 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
15 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
16 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
17 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
18 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
19 with the IEC also participate in this
...
