MEDICAL ELECTRICAL EQUIPMENT –
Part 2-16: Particular requirements for the safety of haemodialysis,
haemodiafiltration and haemofiltration equipment
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical reports or guides and they are accepted by the National Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60601-2-16 has been prepared by subcommittee 62D:
Electromedical equipment, of IEC technical committee 62: Electrical equipment in medical
practice.
The text of this standard is based on the following documents:
FDIS Report on voting
62D/254/FDIS 62D/271/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
Annex AA is for information only.
In this standard, the following print types are used:
– requirements, compliance with which can be tested and definitions: roman type;
– explanations, advice, notes, general statements and exceptions: smaller type;
– test specifications: italic type;
– TERMS USED THROUGHOUT THIS PARTICULAR STANDARD WHICH HAVE BEEN DEFINED IN CLAUSE 2
AND IN IEC 60601-1: SMALL CAPITALS.

INTRODUCTION
The minimum safety requirements specified in this particular standard are considered to
provide for a practical degree of safety in the operation of HAEMODIALYSIS, HAEMODIAFILTRATION
and HAEMOFILTRATION EQUIPMENT.
This particular standard does not take into consideration the specific safety aspects of systems
using regeneration of DIALYSING FLUID.
This particular standard amends and supplements IEC 60601-1 (second edition, 1988): Medical
electrical equipment – Part 1: General requirements for safety, as amended by its amendment
1 (1991) and amendment 2 (1995), hereinafter referred to as the General Standard (see 1.3).
The requirements are followed by specifications for the relevant tests.
Following the decision taken by subcommittee 62D at the meeting in Washington in 1979, a
"General guidance and rationale" section giving some explanatory notes, where appropriate,
about the more important requirements is included in annex AA.
Clauses or subclauses for which there are explanatory notes in annex AA are marked with an
asterisk (*).
It is considered that a knowledge of the reasons for these requirements will not only facilitate
the proper application of the standard but will, in due course, expedite any revision neces-
sitated by changes in clinical practice or as a result of developments in technology. However,
this annex does not form part of the requirements of this standard.

accidental wetting) no SAFETY HAZARD shall result.
Compliance is checked by the following test.
The EQUIPMENT is placed in the position of NORMAL USE and subjected for 30 s to an artificial
rainfall of 3 mm/min falling vertically from a height of 0,5 m above the top of the EQUIPMENT.
A test apparatus is shown in figure 3 of IEC 60529. The test is carried out using tap water. An

30 s exposure, visible moisture on the BODY OF THE EQUIPMENT shall be removed.
Immediately after the above test, inspection shall show that the tap water which may have
entered the EQUIPMENT does not wet parts which may cause a SAFETY HAZARD. In case of
doubt, the EQUIPMENT shall be subjected to the dielectric strength test specified in clause 20 of
the General Standard and it shall function normally.
*44.4 Leakage
Replacement:
The liquid-carrying parts of the EQUIPMENT shall be so shielded against the electrical parts that

---------------------- Page: 17 ----------------------
SIST EN 60601-2-16:1998
– 12 – 60601-2-16 © IEC:1998(E)
By means of a pipette, drops of tap water are applied to couplings, to seals and to hoses which
might rupture, moving parts being in operation or at rest, whichever is the less favourable.
After these procedures, the EQUIPMENT shall show no signs of wetting of uninsulated LIVE parts
or of electrical insulation which is liable to be adversely affected by tap water. In case of doubt,
the EQUIPMENT shall be subjected to the dielectric strength test as specified in clause 20 of the
General Standard.
The likelihood of other SAFETY HAZARDS is checked by inspection.
In case of doubt when using the above compliance test, the following test may be used.
The test is carried out using the liquid appropriate to that part of the EQUIPMENT. By means of a
syringe, a jet of the liquid is directed from couplings, from seals and from hoses that might
rupture, moving parts being in operation or at rest, whichever is the less favourable. After these
EQUIPMENT LIVE
procedures the shall show no signs of wetting of uninsulated parts or of
electrical insulation which is liable to be adversely affected by the liquid. In case of doubt, the
EQUIPMENT
shall be subjected to the dielectric strength test specified in clause 20 of the
General Standard.

51.2 Indication of parameters relevant to safety
Addition:
If the EQUIPMENT can be used for different operation modes, the selected operation mode shall
be obvious to the OPERATOR.
Compliance is checked by inspection.
*51.101 DIALYSING FLUID composition
a) The EQUIPMENT shall include a PROTECTIVE SYSTEM, independent of any fluid preparation
control system, which prevents the DIALYSING FLUID from reaching the DIALYSER, which, due
to its composition, may cause a SAFETY HAZARD.
NOTE – An acceptable method of complying with this requirement is for example a PROTECTIVE SYSTEM utilizing
measurement of conductivity by a temperature compensated (25 °C) method.
b) Operation of the PROTECTIVE SYSTEM shall achieve the following safe conditions:
– activation of an audible and visual alarm (see 51.107);
– stopping of the DIALYSING FLUID flow to the DIALYSER.
Compliance is checked by inspection of the ACCOMPANYING DOCUMENTS and by functional tests.
