GENERAL TESTING PROCEDURES
FOR MEDICAL ELECTRICAL EQUIPMENT

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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC 62354, which is a technical report, 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.
This third edition cancels and replaces the second edition published in 2009. This edition

INTRODUCTION
IEC/TR 60513, Fundamental aspects of safety standards for medical electrical equipment
published by IEC sub-committee 62A provided the basis for inclusion of the test methods for
ME EQUIPMENT in the safety standards.
"Technical requirements and test methods are interrelated elements of product standards and
should always be considered together.
Product standards should identify where medically informed judgements are required in
deciding whether a particular requirement applies.
Wherever possible, the standards should contain test specifications for completely and clearly
checking compliance with the technical requirements. In some cases, a compliance statement
such as 'visual inspection', 'manual testing' or similar is adequate for this purpose if such a
method gives an accurate assessment.
It should be easy to recognize which test methods apply to each technical requirement.
Appropriate headings should designate the appropriate test and a reference should be made
to the clause containing the requirement. This also applies for references which are made to
other relevant test standards."
It was deemed necessary to support IEC 60601-1 with guidelines for general testing
PROCEDURES for MEDICAL ELECTRICAL EQUIPMENT.
In developing the test PROCEDURES, the advice given in IEC/TR 60513 and ISO/IEC Guide 51
was considered as follows:
a) test results should be reproducible within defined limits. When considered necessary, the
test method should incorporate a statement as to its limit of uncertainty;
b) where the sequence of tests can influence the results, the correct sequence should be
specified.
There is also growing support for the idea that all the test PROCEDURES for ME EQUIPMENT
should be found within one international standard.
ISO/IEC 17025, General requirements for the competence of testing and calibration
laboratories, highlights the need for a single series of requirements covering test
PROCEDURES.
IEC/TR 60513 includes a major new principle referring to testing:
“In specifying minimum safety requirements, provision is made for assessing the
adequacy of the design PROCESS where this provides an appropriate alternative to the
application of laboratory testing with specific pass/fail criteria, (e.g. in assessing the
safety of new technologies such as programmable electronic systems).”

4 Types of tests
4.1 GENERAL
“TYPE TESTS” are required for verifying the BASIC SAFETY and ESSENTIAL PERFORMANCE of the
product design.
NOTE 1 The tests described in this technical report can also be used by the MANUFACTURER to ensure the quality
of the product and the manufacturing PROCESS. See Annex I.
A test need not be carried out if analysis shows that the condition being tested has been
adequately evaluated by other tests or methods.
The results of the RISK ANALYSIS should additionally be used to determine which
combination(s) of simultaneous faults should be tested.
NOTE 2 The test results might render it necessary to revise the RISK ANALYSIS.
When testing the ME EQUIPMENT, relevant information provided by the MANUFACTURER in the
instruction for use should be taken into account.
Before commencing testing, the ME EQUIPMENT under test (the device under test or DUT)
should be disconnected from the SUPPLY MAINS. If not possible, special precautions should be
taken to prevent HARM to the personnel performing the tests and measurements or other
individuals who might be affected.
Connections such as data lines or functional earth conductors can act like PROTECTIVE EARTH
CONNECTIONS. Such additional, but unintentional, PROTECTIVE EARTH CONNECTIONS can create
measurement errors.
Unless otherwise specified in IEC 60601-1, ME EQUIPMENT is to be tested under the least
favourable working conditions. The working conditions are specified in the ACCOMPANYING
DOCUMENTS. The least favourable working conditions are to be documented for every test
where they apply.
Considering the ambient temperature, humidity and pressure described in the technical
description, tests should be performed at the worst-case extremes depending on the test and
the effects of these parameters on the test results. If the test is not impacted by these
parameters, then test can be conducted anywhere within the specified range.

4.2 Visual inspection
Covers and housings should be opened only:
– if required in the instructions for use for the ME EQUIPMENT, or
– if specified in this technical report, or
– if there is an indication of a HAZARD or HAZARDOUS SITUATION.
Special attention should be paid to the following:
– all fuses accessible from the outside should be marked (type, ratings) on the
ME EQUIPMENT or marked by reference and specified in the ACCOMPANYING DOCUMENTS;
– the markings are legible and complete;
– any damage;
– relevant ACCESSORIES should be assessed together with the ME EQUIPMENT (e.g.
DETACHABLE or FIXED POWER SUPPLY CORDS, PATIENT leads, tubing etc.);
– all required documentation, such as instructions for use, is present and complete and
reflects the current revision of the ME EQUIPMENT.
5 State of the ME EQUIPMENT
Some tests specified in this document are conducted in the NORMAL CONDITION whilst others
are conducted in SINGLE FAULT CONDITIONS.
NORMAL CONDITION and SINGLE FAULT CONDITIONS are described in both IEC 60601-1:1988 and
IEC 60601-1:2005.
6 Number of samples
TYPE TESTS are performed on a representative sample of the item being assessed.
Multiple samples can be utilized simultaneously if the validity of the results is not significantly
affected.
7 Applicable test items to the clauses of IEC 60601-1
Table 2, Table 5 and Table 10 relate the test PROCEDURES described in this technical report to
the relevant subclauses of IEC 60601-1:2005. When applicable, these tables also provide a
cross reference to the relevant subclauses of IEC 60601-1:1988.
Annex G and Annex H contain an index of the tests in this technical report sorted by the
relevant subclause in IEC 60601-1:2005. Annex I and Annex J contain the lists sorted in
alphabetical order by test title.
8 Sequence of tests
Unless stated otherwise, the tests in this technical report are to be sequenced in such a way
so that the results of any test do not influence the results of other tests. Tests should, if
applicable, be performed in the sequence indicated in Annex A, unless otherwise stated by
particular standards.
However, this does not preclude the possibility of conducting a test that preliminary inspection
suggests might cause failure.

The tests for radiation HAZARDS, biocompatibility, USABILITY, alarm systems, PEMS and
electromagnetic compatibility can be performed independently from the tests specified in the
present document.
The tests specified for ME SYSTEMS should be performed in the same sequence as the tests
for ME EQUIPMENT.
9 General testing condition
The following general testing conditions should be applied:
NORMAL USE, tests are carried out under the least
a) After the DUT has been set up for
favourable working conditions which are specified in the ACCOMPANYING DOCUMENTS.
b) The DUT is to be shielded from other influences (for example, draughts) that might affect
the validity of the tests.
c) In cases where ambient temperatures cannot be maintained, the test conditions are to be
consequently modified and results adjusted accordingly.
d) Qualified personnel are to perform these tests. Qualifications include training on the
subject, knowledge, experience, and acquaintance with the relevant technologies and
regulations. The personnel should be able to assess safety and should be able to
recognize possible consequences and HAZARDS arising from non-conforming
ME EQUIPMENT
e) ACCESSORIES for the ME EQUIPMENT, which can affect the safety of the DUT or the results
of the measurements, should be included in the tests. ACCESSORIES included in the tests
are to be documented.
RISK arises for testing
f) All tests are to be performed in such a manner that no unacceptable
personnel, PATIENTS or other individuals.
g) If not otherwise stated, all values for current and voltage are effective values (r.m.s.) or
d.c. values as appropriate.
h) All tests performed should be comprehensively documented. The documentation should
contain as a minimum the following data:
– identification of the testing body (e. g. company, department);
– names of the persons, who performed the
...
