7 AMENDMENT 1
10 FOREWORD
11 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
12 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
13 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
14 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
15 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
16 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
17 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
18 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
19 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
20 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
21 consensus of opinion on the relevant subjects since each technical committee has representation from all
22 interested IEC National Committees.
23 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
24 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
25 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
26 misinterpretation by any end user.
27 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
28 transparently to the maximum extent possible in their national and regional publications. Any divergence between
29 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
30 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
31 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
32 services carried out by independent certification bodies.
33 6) All users should ensure that they have the latest edition of this publication.
34 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
35 members of its technical committees and IEC National Committees for any personal injury, property damage or
36 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
37 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
38 Publications.
39 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
40 indispensable for the correct application of this publication.
41 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
42 rights. IEC shall not be held responsible for identifying any or all such patent rights.
43 Amendment 1 to IEC 62061:2021 has been prepared by IEC technical committee 44: Safety of
44 machinery – Electrotechnical aspects.
45 The text of this Amendment is based on the following documents:
