FOREWORD
This amendment has been prepared by subcommittee 62A: Common aspects of electrical
equipment used in medical practice, of IEC technical committee 62: Electrical equipment in
medical practice.
The text of this amendment is based on the following documents:
FDIS Report on voting
62A/1389/FDIS 62A/1404/RVD
Full information on the voting for the approval of this amendment can be found in the report on
voting indicated in the above table.
The committee has decided that the contents of this amendment and the base publication will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
NOTE The attention of the users of this document is drawn to the fact that equipment manufacturers and testing
organizations may need a transitional period following publication of a new, amended or revised IEC or ISO
publication in which to make products in accordance with the new requirements and to equip themselves for
conducting new or revised tests. It is the recommendation of the committee that the content of this publication be
adopted for mandatory implementation nationally not earlier than 3 years from the date of publication.

INTRODUCTION TO AMENDMENT 2
The third edition of IEC 60601-1 was published in 2005 and amended in 2012. Since the
publication of IEC 60601-1:2005/AMD1:2012, the IEC Subcommittee (SC) 62A Secretariat has
been collecting issues from a variety of sources including comments from National Committees
and questions submitted to IEC/SC 62A/Working Group (WG) 14. At the November 2015
meeting of IEC/SC 62A in Kobe, Japan, the subcommittee initiated a process to identify high-
priority issues that need to be considered in Amendment 2 and should not wait until the fourth
edition of IEC 60601-1, which is presently targeted for publication sometime after 2024.
Those issues selected for inclusion on the final "short list" to be addressed in Amendment 2
were those approved by a 2/3 majority of the National Committees present and voting at the
Frankfurt meeting of SC 62A. At the meeting held on 10 October 2016, 109 items were
presented to the National Committees present. A total of 78 items received the required 2/3
majority of the National Committees present and voting and were included in the "short list" for
consideration in preparing Amendment 2. All remaining issues have been placed on a "long list"
for consideration in the fourth edition of IEC 60601-1.
The "short list" of issues was documented in the design specification for Amendment 2. The
responsible expert groups were directed to consider each issue assigned to it in Clause 6 of
the design specification and develop an appropriate solution for the identified problem. That
final solution in this amendment can encompass any technical solution proposed by the author
of the issue or it can involve a different solution developed by the expert group. The expert
group can also have recommended that no change to the standard was justified by the problem
statement.
Because this is an amendment to the 2005 edition of IEC 60601-1, the style in force at the time
of publication of IEC 60601-1 has been applied to this amendment. The style specified in
ISO/IEC Directives, Part 2:2018 has only been applied when implementing the new style
guidance would not result in additional editorial changes. For example, notes to definitions are
designated as "NOTE" rather than "Note to entry" in Clause 3.
Users of this document should note that when constructing the dated references to specific
elements in a standard, such as definitions, amendments are only referenced if they modified
the text being cited. For example, if a reference is made to a definition that has not been
modified by an amendment, then the reference to the amendment is not included in the dated
reference.

are incorporated by a normative reference to IEC 60950-1:2005. For example, the requirements
for solid insulation forming a MEANS OF OPERATOR PROTECTION in 8.5.1.3. The requirements
incorporated by reference are primarily found in Clause 8 of this document, including many of
the tables used to determine the requirements for MEANS OF PROTECTION, primarily MEANS OF
OPERATOR PROTECTION and INSULATION CO-ORDINATION. The requirements incorporated by
