AMENDMENT 2
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 formal 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 Committees.

3) 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 made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

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 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.

6) All 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 experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

Amendment 2 to IEC 61975:2010 has been prepared by subcommittee 22F: Power electronics

for electrical transmission and distribution systems, of IEC technical committee 22: Power

electronic systems and equipment.
The text of this Amendment is based on the following documents:

As the plenary meeting of SC 22F was cancelled in 2020 due to COVID-19 pandemic (see 22F/591/INF), the

decision to begin the review of IEC 61975 AMD1 ED1 by SC 22F/MT 27 in 2021 was proposed by SC 22F

secretariat and was supported by 100% voting of SC 22F P-members (see 22F/599/DC, 22F/609/INF).

It was noted that the Swedish IEC National Committee made 150 (!) comments on document 22F/638/CD but

most of them referred to the basic document IEC 61975 ED1.1 but not to the Amendment 1.

Compilation of comments 22F/665A/CC on document 22F/638/CD was considered by the secretary of SC 22F,

the Chair of SC 22F, Convenor and members of SC22F/MT27. It was decided to take into account only

comments referred to Amendment 1 as the rest ones could be used only for the revision of IS 61975 but not for

its review.

The Chair of SC 22F made decision (supported by the secretary of SC 22F) to prepare a CDV by putting agreed

changes into 22F/638/CD by 2021-12.
