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, Techni ca l S pe cif i cat i ons,
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 intereste d
in the subject dealt with may participate in this preparat ory w ork. In t ern at i on al , go vern me nt al a n d n on -
governmental organizations liaising with the IEC also participate in this preparation. IEC collabo rat es cl o sel y
w ith the International Organization for Standardization (ISO) in accordance w i t h co nd i ti o ns d et ermi n e d b y
agreement between the tw o organizations.
2) The f ormal 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 committ ee h as r ep resen ta ti o n f ro m a l l
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accep te d b y IEC Na t i o n a l
Committees in that sense. While all reasonable efforts are made to ensure that the tech ni cal c on te nt of IEC
Publications is accurate, IEC cannot be held responsi ble for the w ay in w hich they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake t o a pp l y IEC Pu b l i c a ti o ns
transparently to the maximum extent possible in their national and r egional publications. Any divergence
betw een any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies pro vid e c onf o rmi ty
assessment services and, in some areas, access to IEC marks of conformity. IEC is not r esp onsi b l e f o r a ny
services carried out by independent certification bodies.
6) A ll users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual e xpe rts a n d
members of its technical committees and IEC National Committees for any personal injury, property damage o r
other damage of any nature whatsoever, whether direct or indirect, or for c osts ( i ncl ud i ng l e ga l f ees) a n d
expenses arising out of the publication, use of, or rel i a nce u p on , t h is IEC Pu b l i c a t i on o r a ny o t he r IEC
Publications.
8) A ttention is drawn to the Normative references cited in this publication. Use of the referenced p ub l i cat i ons i s
indispensable for the correct application of this publication.
9) A ttention is drawn to the possibility that some of the elements of this IEC Publicatio n ma y be t he su bj ect of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
The main task of IEC technical committees is to prepare International Standards. Ho w e ve r , a
technical committee may propose the publication of a technical report when i t has c ol l ec ted
data of a different kind from that which is normally published as an International Standard, fo r
example "state of the art".
IEC TR 63201, which is a technical report, has been
