AMENDMENT 1
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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to IEC 62271-200:2021 has been prepared by subcommittee 17C: Assemblies,
of IEC technical committee 17: High-voltage switchgear and controlgear.
The text of this Amendment is based on the following documents:
Draft Report on voting

This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications/.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under webstore.iec.ch in the data related to the
specific document. At this date, the document will be
• reconfirmed,
• withdrawn, or

INTRODUCTION
Add, at the end of the existing text, the following new paragraph:
Generally, gas-filled medium-voltage designs have design pressures below 500 kPa, as
mentioned for example in the introduction of EN 50187.
2 Normative references
Delete the existing reference to IEC 62271-203:2011.
Add the following normative reference:
ISO 4126-2, Safety devices for protection against excessive pressure – Part 2: Bursting disc
safety devices
3 Terms and definitions
Replace the existing 3.6.101 term, definition and notes to entry with the following:
3.6.101
loss of service continuity category
LSC
category defining the possibility to keep other high-voltage compartments
and/or functional units energized when opening its connection compartment or any other of its
high-voltage compartment(s) accessible in normal use, as stated in definitions 3.5.110 and
3.5.111, giving access to at least part of the high-voltage circuit contained within
Note 1 to entry: The LSC category describes the extent to which the assembly is intended to remain operational
where access to a high-voltage compartment is provided. The extent to which it is considered necessary to open
high-voltage compartments of an installation in service might be dependent on several aspects (refer to 9.101).
Note 2 to entry: The LSC category does not describe or relate to different levels of reliability of assemblies (refer
to 9.101).
Note 3 to entry: In relation to providing access to high-voltage compartments and the associated service continuity,
four categories are defined: LSC1, LSC2, LSC2A, LSC2B (refer to Annex D).
