87 SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT

90 Part 2-201: Particular requirements for control equipment
92 FOREWORD
93 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
94 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
95 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
96 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
97 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
98 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
99 in the subject dealt with may participate in this preparatory work. International, governmental and non-
100 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
101 with the International Organization for Standardization (ISO) in accordance with conditions determined by
102 agreement between the two organizations.
103 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
104 consensus of opinion on the relevant subjects since each technical committee has representation from all
105 interested IEC National Committees.
106 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
107 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
108 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
109 misinterpretation by any end user.
110 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
111 transparently to the maximum extent possible in their national and regional publications. Any divergence
112 between any IEC Publication and the corresponding national or region
