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/1390/FDIS 62A/1405/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• withdrawn,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 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.
IMPORTANT – The 'colour inside' logo on the cover page of this publication indicates
that it contains colours which are considered to be useful for the correct understanding

INTRODUCTION TO AMENDMENT 1
The fourth edition of IEC 60601-1-2 was published in 2014. Since the publication of
IEC 60601-1-2:2014, the IEC Subcommittee (SC) 62A Secretariat has been collecting issues
from a variety of sources including comments from National Committees. 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 an amendment and should not wait until the fifth
edition of IEC 60601-1-2, which is presently targeted for publication sometime after 2024.
Those issues selected for inclusion on the final "short list" to be addressed in Amendment 1
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, 15 items were presented
to the National Committees present. All 15 items received the required 2/3 majority of the
National Committees present and voting and have been included in the "short list" for
consideration in preparing Amendment 1. All remaining issues have been placed on a "long list"
for consideration in the fifth edition of IEC 60601-1-2.
The "short list" of issues was documented in the design specification for Amendment 1. MT 23
was directed to consider each issue described 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 IEC 60601-1-2:2014, the style in force at the time of
publication of IEC 60601-1-2 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.
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.
