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.

201.1.2 Object
Replacement:
The object of this particular standard is to establish BASIC SAFETY and ESSENTIAL PERFORMANCE
requirements for HAEMODIALYSIS EQUIPMENT.
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, IEC 60601-1-8:2006 and IEC 60601-1-8:2006/AMD1:2012,
IEC 60601-1-10:2007 and IEC 60601-1-10:2007/AMD1:2013 and IEC 60601-1-11:2015 apply
as modified in Clauses 202, 208, 210 and 211. IEC 60601-1-3 and IEC 60601-1-12 do not
apply. IEC 60601-1-9:2007 and IEC 60601-1-9:2007/AMD1:2013 does not apply as noted in
Clause 209. All other published collateral standards in the IEC 60601-1 series apply as
published.
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

– 10 – IEC 60601-2-16:2018 © IEC 2018
numbered beginning from 201.3.201. Additional annexes are lettered AA, BB, etc., and
additional items aa), bb), etc.
Subclauses, figures or tables which are additional to those of a collateral standard are
numbered starting from 20x, where "x" is the number of the collateral standard, for example
202 for IEC 60601-1-2, 203 for IEC 60601-1-3, etc.
The term "this document" is used to make reference to the general standard, any applicable
collateral standards and this particular standard taken together.
Where there is no corresponding clause or subclause in this particular standard, the clause or
subclause of the general standard or applicable collateral standard, although possibly not
relevant, applies without modification; where it is intended that any part of the general
standard or applicable collateral standard, although possibly relevant, is not to be applied, a
statement to that effect is given in this particular standard.
