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