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 particular standard deals with the safety of INFUSION PUMPS and INFUSION CONTROLLERS.
The relationship between this particular standard, IEC 60601-1:2005+A1:2012, and the
collateral standards is explained in 1.3.
The safe use of INFUSION PUMPS and controllers is primarily the responsibility of the OPERATOR.
It is also recognized that OPERATORS should be trained in the operation of MEDICAL ELECTRICAL
EQUIPMENT and that safe use of the MEDICAL ELECTRICAL EQUIPMENT can only be achieved if it is
operated in accordance with the MANUFACTURER’S instructions for use. The minimum specified
safety requirements are considered to provide a practical degree of safety in operation. It is
the responsibility of the MANUFACTURER to ensure that the requirements of this particular
standard are reliably implemented. This particular standard has been developed in
accordance with these principles.

MEDICAL ELECTRICAL EQUIPMENT –

Part 2-24: Particular requirements for the basic safety and essential
performance of infusion pumps and controllers

201.1 Scope, object and related standards
Clause 1 of the general standard applies, except as follows:
201.1.1 Scope
Replacement:
This Particular Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of INFUSION
PUMPS and VOLUMETRIC INFUSION CONTROLLERS, hereafter referred to as ME EQUIPMENT.
This standard applies to ADMINISTRATION SETS insofar as their characteristics influence the
BASIC SAFETY or ESSENTIAL PERFORMANCE of INFUSION PUMPS and VOLUMETRIC INFUSION
CONTROLLERS. However this standard does not specify requirements or tests for other aspects
of ADMINISTRATION SETS
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.
HAZARDS inherent in the intended physiological function of ME EQUIPMENT or ME SYSTEMS
within the scope of this standard are not covered by specific requirements in this standard
except in 7.2.13 and 8.4.1 of the general standard.
NOTE See also 4.2 of the general standard.
This particular standard specifies the requirements for ENTERAL NUTRITION PUMPS, INFUSION
PUMPS, INFUSION PUMPS FOR AMBULATORY USE, SYRINGE OR CONTAINER PUMPS, VOLUMETRIC
INFUSION CONTROLLERS and VOLUMETRIC INFUSION PUMPS, as defined in 201.3.204, 201.3.206,
201.3.207, 201.3.220, 201.3.222 and 201.3.223.
These particular standard does not apply to the following:
a) devices specifically intended for diagnostic or similar use (e.g. angiography or other
pumps permanently controlled or supervised by the OPERATOR);
b) devices for extracorporeal circulation of blood;
c) implantable devices;
d) ME EQUIPMENT specifically intended for diagnostic use within urodynamics (measurement
of pressure-volume relationship of the urinary bladder when filled through a catheter with
water);
e) ME EQUIPMENT specifically intended for diagnostic use within male impotence testing
(measurement of amount of liquid infused, necessary to maintain a preset pressure level
for maintaining penile erection: cavernosometry, cavernosography);
f) devices covered by ISO 28620.

The general standard is IEC 60601-1:2005+A1:2012, Medical electrical equipment – Part 1: General
requirements for basic safety and essential performance.

– 8 – 60601-2-24  IEC:2012
201.1.2 Object
Replacement:
The object of this particular standard is to establish particular BASIC SAFETY and ESSENTIAL
PERFORMANCE requirements for ENTERAL NUTRITION PUMPS, INFUSION PUMPS, INFUSION PUMPS
FOR AMBULATORY USE, SYRINGE OR CONTAINER PUMPS, VOLUMETRIC INFUSION CONTROLLERS and
VOLUMETRIC INFUSION PUMPS, as defined in 201.3.204, 201.3.206, 201.3.207, 201.3.220,
201.3.222 and 201.3.223.
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 60601-1-2:2007, IEC 60601-1-6:2010 and IEC 60601-1-8:2006 apply as modified in
Clauses 202, 206 and 208 respectively. IEC 60601-1-3 does not apply. 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 is 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 standard 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 60601-1-2 collateral standard,
203.4 in this particular standard addresses the content of Clause 4 of the 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 3.139, additional definitions in this standard are
numbered beginning from 201.3.201. Additional annexes are lettered AA, BB, etc., and
additional items aa), bb), etc.

60601-2-24  IEC:2012 – 9 –
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, e.g. 202 for
IEC 60601-1-2, 203 for IEC 60601-1-3, etc.
The term "this standard" 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.
