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 IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
This part of IEC 80601 is written at a time when technical evolution of medical robots is in
rapid progress and the scientific foundation of safe use is still being expanded.
This document is the result of work that began in ISO/TC 184/SC 2/WG 7 in October 2006 on
personal care robots, to address an emerging type of medical robot that was used outside of
1 2
an industrial environment . That group was working on a new standard, ISO 13482[1] , which
was published as an International Standard (IS) in 2014. While initially focused on non-
medical applications, WG 7 recognized that work was likely to be needed on medical devices
utilizing robotic technology. In October 2009, ISO/TC 184/SC 2 established a WG 7, Study
Group (SG) on Medical care robots, comprised of experts from Canada, France, Germany,
Japan, Korea, Romania, Switzerland, UK and USA.
The work of ISO/TC 184/SC 2/WG 7 SG cumulated in a proposal to form a Joint Working
Group (JWG 9) with IEC/TC 62/SC 62A focusing on MEDICAL ELECTRICAL EQUIPMENT using
robotic technology. This JWG began developing a technical report (IEC TR 60601-4-1:2017[2])
dealing with degree of autonomy. While developing this document, a particular standard was
proposed for robotic equipment used in surgical applications. This led to the creation of a
Joint Working Group 35 in April 2015 within IEC/TC 62/SC 62D to develop particular
requirements of safety of MEDICAL ELECTRICAL EQUIPMENT and MEDICAL ELECTRICAL SYSTEMS
that utilize robotic technology. The work would include medical robots for SURGERY. This
proposal was approved, resulting in the formation of Joint Working Group (JWG 35).
During IEC/TC 62/SC 62D discussion, there was a strong opinion that some types of MEDICAL
ELECTRICAL EQUIPMENT could be a medical robot, but not all MEDICAL ELECTRICAL EQUIPMENT
were medical robots. According to this opinion, JWG 35 discussed and agreed that the
majority of existing MEDICAL ELECTRICAL EQUIPMENT, including those used for surgical
PROCEDURES, were not considered medical robots, so it would be better to capture this type of
ME EQUIPMENT through a different definition – ROBOTICALLY ASSISTED SURGICAL EQUIPMENT
(RASE).
JWG 9 defined medical robots as ME EQUIPMENT with a degree of autonomy
(IEC TR 60601-4-1:2017). JWG 35 found that some RASE have zero autonomy. Therefore, by
definition, RASE could not be equivalent to a medical robot. Regulatory agencies objected to
employ the term robot as defined in IEC TR 60601-4-1 and felt that it implied that the RASE
were performing the surgical PROCEDURE rather than the surgeon. The consensus in JWG 35
was that the RASE only assists the surgeon. The surgeon maintains some level of control or
supervision of the RASE.
The minimum safety requirements specified in this particular standard for ROBOTICALLY
ASSISTED SURGICAL EQUIPMENT are presumed to establish that the RESIDUAL RISKS have been
reduced to acceptable levels unless there is OBJECTIVE EVIDENCE to the contrary.
The requirements are followed by particular specifications for the relevant tests.

201.1.1 Scope
Replacement:
This part of IEC 80601 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of
ROBOTICALLY ASSISTED SURGICAL EQUIPMENT (RASE) and ROBOTICALLY ASSISTED SURGICAL
SYSTEMS (RASS), hereafter referred to as ME EQUIPMENT and ME SYSTEMS together with their
INTERACTION CONDITIONS and INTERFACE CONDITIONS. If a clause or subclause is specifically
intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of
that clause or subclause will say so. If that is not the case, the clause or subclause applies
both to ME EQUIPMENT and to ME SYSTEMS, as relevant.
If RASE or RASS, or its ACCESSORIES fall within scope of another particular standard, then the
particular standard applies in addition to this standard.
EXAMPLES IEC 60601-2-2[3] for HF SURGICAL EQUIPMENT; IEC 60601-2-18[4] for ENDOSCOPIC EQUIPMENT;
IEC 60601-2-22[5] for laser equipment; IEC 60601-2-37[6] for ultrasound equipment; IEC 60601-2-46[7] for
operating tables, etc.
201.1.2 Object
Replacement:
The object of this particular standard is to establish particular BASIC SAFETY and ESSENTIAL
PERFORMANCE requirements for ROBOTICALLY ASSISTED SURGICAL EQUIPMENT and ROBOTICALLY
ASSISTED SURGICAL SYSTEMS.
201.1.3 * Collateral standards
Addition:
This particular standard refers to those applicable collateral standards that are listed in
Clause 2 of the general standard and Clause 201.2 of this particular standard.
IEC 60601-1-2:2014 and IEC 60601-1-6:2010 and IEC 60601-1-6:2010/AMD1:2013 apply as
modified in Clauses 202 and 206 respectively. IEC 60601-1-3:2008 and
IEC 60601-1-3:2008/AMD1:2013[8], IEC 60601-1-9:2007 and
IEC 60601-1-9:2007/AMD1:2013[9], and IEC 60601-1-11:2015[10] do not apply.

201.1.4 Particular standards
Replacement:
In the IEC 60601 series, particular standards may modify, replace or delete requirements
contained in the general standard and collateral standards as appropriate for the particular ME
EQUIPMENT under consideration, and may add other BASIC SAFETY and ESSENTIAL PERFORMANCE
requirements.
A requirement of a particular standard takes priority over the general standard.
For brevity, IEC 60601-1:2005 and IEC 60601-1:2005/AMD1:2012 are referred to in this
particular standard as the general standard. Collateral standards are referred to by their
document number.
The numbering of clauses and subclauses of this particular standard corresponds to that of
the general standard with the prefix "201" (e.g. 201.1 in this document addresses the content
of Clause 1 of the general standard) or applicable collateral standard with the prefix "20x",
where x is the final digit(s) of the collateral standard document number (e.g. 202.4 in this
particular standard addresses the content of Clause 4 of the IEC 60601-1-2 collateral
standard, 203.4 in this particular standard addresses the content of Clause 4 of the
IEC 60601-1-3 collateral standard, etc.). The changes to the text of the general standard are
specified by the use of the following words:
"Replacement" means that the clause or subclause of the general standard or applicable
collateral standard is replaced completely by the text of this particular standard.
"Addition" means that the text of this particular standard is additional to the requirements of
the general standard or applicable collateral standard.
"Amendment" means that the clause or subclause of the general standard or applicable
collateral standard is amended as indicated by the text of this particular standard.
Subclauses, figures or tables which are additional to those of the general standard are
numbered starting from 201.101. However, due to the fact that definitions in the general
standard are numbered 3.1 through 3.147, additional definitions in this document are
numbered beginning from 201.3.201. Additional annexes are lettered AA, BB, etc., and
additional items aa), bb), etc.
