`
`FOREWORD
`
`1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
`all national electrotechnical committees
`(IEC National Committees). The object of
`IEC is
`to promote
`international co-operation on all questions concerning standardization in the electrical and electronic fields. To
`this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
`Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter
`referred to as “IEC
`Publication(s}"). Their preparation is entrusted to technical committees; any IEC National Committee interested
`in the subject dealt with may participate in this preparatory work,
`International, governmental and non-
`governmental organizations liaising with the IEC also participate in this preparation.
`IEC collaborates closely
`with the International Organization for Standardization (ISO)
`in accordance with conditions determined by
`agreement between the two organizations.
`2) The fermal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
`consensus of opinion on the relevant subjects since each technical committee has representation from all
`interested IEC National Cammittees,
`
`3)
`
`4)
`
`IEC Publications have the form of recommendations for international use and are accepted by IEC National
`Committees in that sense, While all reasonable efforts are mace to ensure that the technical content of IEC
`Publications is accurate,
`JEC cannot be held responsible for the way in which they are used or for any
`misinterpretation by any end user.
`[EC National Committees undertake to apply IEC Publications
`In order to promote international uniformity,
`transparently to the maximum extent possible in their national and regional publications. Any divergence
`between any ![EC Publication and the corresponding national or regional publication shall be clearly indicated in
`the latter.
`
`5
`
`IES itself does not provide any attestation of conformity. Independent certification bodies provide conformity
`assessment services and, in some areas, access to IEC marks of conformity.
`IEC is not responsible for any
`services carried out by independent certification bodies.
