Medical electrical equipment - Recurrent test and test after repair of medical electrical equipment
This International Standard applies to testing of MEDICAL ELECTRICAL EQUIPMENT and MEDICAL
ELECTRICAL SYSTEMS, hereafter referred to as ME EQUIPMENT and ME SYSTEMS, or parts of such
equipment or systems, which comply with IEC 60601-1:1988 (second edition) and its
amendments and IEC 60601-1: 2005 (third edition) and its amendments, before PUTTING INTO
SERVICE, during MAINTENANCE, INSPECTION, SERVICING and after REPAIR or on occasion of
RECURRENT TESTS to assess the safety of such ME EQUIPMENT or ME SYSTEMS or parts thereof.
For equipment not built to IEC 60601-1 these requirements may be used taking into account
the safety standards for the design and information in the instructions for use of that
equipment.
This standard contains tables with allowable values relating to different editions of
IEC 60601-1. For the purpose of this standard, the application of measuring methods is
independent of the edition according to which the ME EQUIPMENT or ME SYSTEM is designed.
This standard contains:
– "general requirements", which contain clauses of general concern, and
– "particular requirements", further clauses handling special types of ME EQUIPMENT or
ME SYSTEMS and applying in connection with the "General requirements".
NOTE At this stage, there are no particular requirements.
This standard is not suitable to assess whether ME EQUIPMENT or ME SYSTEMS or any other
equipment comply with the relevant standards for their design.
This standard is not applicable to the assembly of ME SYSTEMS. For assembling ME SYSTEMS
see Clause 16 of IEC 60601-1:2005 + IEC 60601-1:2005/AMD1:20121.
This standard does not define requirements for REPAIR, exchange of components and
MODIFICATION of ME EQUIPMENT or ME SYSTEMS.
All MAINTENANCE, INSPECTION, SERVICING, and REPAIR done in accordance with
MANUFACTURER's instructions maintain the conformity to the standard used for the design of
the equipment. Otherwise conformity to applicable requirements should be assessed and
verified, before the tests of this standard are performed.
This standard is also applicable to tests after REPAIR.
IEC 60601-1:2005 + IEC 60601-1:2005/AMD1:2012 requires that, as part of the RISK
MANAGEMENT PROCESS, the MANUFACTURER considers how the safety of ME EQUIPMENT or an
ME SYSTEM can be ensured during product lifetime. As part of the risk management process
the MANUFACTURER may have identified MAINTENANCE procedures. This includes defining the
respective tests for ME EQUIPMENT or for ME SYSTEM.The MANUFACTURER may have defined necessary measurement settings and methods
including performance assurance tests in the instructions for use or other ACCOMPANYING
DOCUMENTS. This standard provides consistent test procedures.
This standard is not intended to define time intervals for RECURRENT TESTS. If such intervals
are not defined by the MANUFACTURER, Annex F can be used to help establish such intervals.
Testing of the electrical installation, including the SUPPLY MAINS and associated wiring, in
medical locations is excluded from this standard. Such tests are covered by IEC 60364-7-710
or national equivalents,

Medicinska električna oprema - Ponavljalni preskus in preskus po popravilu medicinske električne opreme (IEC 62353:2014)
Ta mednarodni standard se uporablja za preskušanje MEDICINSKE ELEKTRIČNE OPREME in MEDICINSKIH ELEKTRIČNIH SISTEMOV, v nadaljnjem besedilu: ME OPREMA in ME SISTEMI, ali delov take opreme ali sistemov, ki so v skladu s standardom IEC 60601-1:1988 (druga izdaja) in njegovimi spremembami ter standardom IEC 60601-1:2005 (tretja izdaja) in njegovimi spremembami, pred ZAČETKOM UPORABE, med VZDRŽEVANJEM, INŠPEKCIJSKIMI PREGLEDI, SERVISIRANJEM in po POPRAVILU ali med PONAVLJALNIMI PRESKUSI za oceno varnosti take ME OPREME ali ME SISTEMOV ali njihovih delov. Za opremo, ki ni izdelana v skladu s standardom IEC 60601-1, se lahko te zahteve uporabljajo ob upoštevanju varnostnih standardov za zasnovo in informacije v navodilih za uporabo te opreme.
Ta standard vsebuje preglednice z dovoljenimi vrednostmi v zvezi z različnimi izdajami standarda IEC 60601-1. Za namen tega standarda je uporaba merilnih metod neodvisna od izdaje, v skladu s katero je ME OPREMA ali ME SISTEM zasnovan.
Ta standard vključuje:
– »splošne zahteve«, ki zajemajo splošna določila, in
– »posebne zahteve«, dodatna določila, ki obravnavajo posebne vrste ME OPREME ali ME SISTEMOV in se uporabljajo v zvezi s splošnimi zahtevami.
OPOMBA: Na tej stopnji ni posebnih zahtev.
Ta standard ni primeren za oceno, ali je ME OPREMA ali ME SISTEMI ali katera koli druga oprema skladna z ustreznimi standardi za njihovo zasnovo.
Ta standard se ne uporablja za sestav ME SISTEMOV. V zvezi s sestavljanjem ME SISTEMOV si oglejte točko 16 standarda IEC 60601-1:2005 + IEC 60601-1:2005/AMD1:20121.
Ta standard ne določa zahtev za POPRAVILO, izmenjavo komponent in SPREMINJANJE ME OPREME ali ME SISTEMOV.
Vse dejavnosti VZDRŽEVANJA, INŠPEKCIJSKIH PREGLEDOV, SERVISIRANJA in POPRAVIL, izvedene v skladu z navodili PROIZVAJALCA, ohranjajo skladnost s standardom, ki se uporablja za zasnovo opreme. Sicer bi bilo treba oceniti in preveriti skladnost z ustreznimi zahtevami pred izvedbo preskusov iz tega standarda.
Ta standard se uporablja tudi za preskuse po POPRAVILU.
V standardu IEC 60601-1:2005 + IEC 60601-1:2005/AMD1:2012 se zahteva, da PROIZVAJALEC v okviru POSTOPKA ZA OBVLADOVANJE TVEGANJA premisli o tem, kako je mogoče zagotoviti varnost ME OPREME ali ME SISTEMA med življenjsko dobo izdelka. Kot del postopka za obvladovanje tveganja lahko PROIZVAJALEC opredeli postopke VZDRŽEVANJA. To vključuje določitev ustreznih preskusov za ME OPREMO ali ME SISTEM. PROIZVAJALEC lahko določi ustrezne merilne nastavitve in metode,
vključno s preskusi za zagotavljanje učinkovitosti v navodilih za uporabo ali drugih SPREMNIH DOKUMENTIH. Ta standard zagotavlja skladne preskusne postopke.
Ta standard ni namenjen določitvi časovnih intervalov za PONAVLJALNE POSKUSE. Če takih intervalov ne določi PROIZVAJALEC, se lahko dodatek F uporabi za pomoč pri opredelitvi takih intervalov. Preskušanje električne inštalacije na medicinskih lokacijah, vključno z NAPAJALNIM OMREŽJEM in povezanim ožičenjem, je izključeno iz tega standarda. Take preskuse obravnava standard IEC 60364-7-710 ali nacionalni ekvivalenti.

MEDICAL ELECTRICAL EQUIPMENT –
RECURRENT TEST AND TEST AFTER REPAIR
OF 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.
International Standard IEC 62353 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 second edition cancels and replaces the first edition of IEC 62353 published in 2007.
This edition constitutes a technical revision. The principle revisions are:
a) clarification in 5.3.4.1 that measurements of leakage currents based on test configurations
derived from IEC 60601-1 are an allowable alternative method and the inclusion of
informative explanation in Annex A;
b) revision of the PROTECTIVE EARTH RESISTANCE requirements for MEDICAL ELECTRICAL
SYSTEMS using multiple socket outlets to take account of IEC 60601-1:2005/AMD1:2012 on
the safe allowed values of protective earth resistance of plugged-in equipment;
c) the inclusion of expected minimum insulation resistance values in Table 2; and
d) a reordering of the sequence of testing in Annex B.

RECURRENT TEST AND TEST AFTER REPAIR
OF MEDICAL ELECTRICAL EQUIPMENT
1 Scope
This International Standard applies to testing of MEDICAL ELECTRICAL EQUIPMENT and MEDICAL
ELECTRICAL SYSTEMS, hereafter referred to as ME EQUIPMENT and ME SYSTEMS, or parts of such
equipment or systems, which comply with IEC 60601-1:1988 (second edition) and its
amendments and IEC 60601-1: 2005 (third edition) and its amendments, before PUTTING INTO
SERVICE, during MAINTENANCE, INSPECTION, SERVICING and after REPAIR or on occasion of
RECURRENT TESTS to assess the safety of such ME EQUIPMENT or ME SYSTEMS or parts thereof.
For equipment not built to IEC 60601-1 these requirements may be used taking into account
the safety standards for the design and information in the instructions for use of that
equipment.
This standard contains tables with allowable values relating to different editions of
IEC 60601-1. For the purpose of this standard, the application of measuring methods is
independent of the edition according to which the ME EQUIPMENT or ME SYSTEM is designed.
This standard contains:
– "general requirements", which contain clauses of general concern, and
– "particular requirements", further clauses handling special types of ME EQUIPMENT or
ME SYSTEMS and applying in connection with the "General requirements".
NOTE At this stage, there are no particular requirements.
This standard is not suitable to assess whether ME EQUIPMENT or ME SYSTEMS or any other
equipment comply with the relevant standards for their design.
This standard is not applicable to the assembly of ME SYSTEMS. For assembling ME SYSTEMS
1
see Clause 16 of IEC 60601-1:2005 + IEC 60601-1:2005/AMD1:2012 .
This standard does not define requirements for REPAIR, exchange of components and
MODIFICATION of ME EQUIPMENT or ME SYSTEMS.
All MAINTENANCE, INSPECTION, SERVICING, and REPAIR done in accordance with
MANUFACTURER's instructions maintain the conformity to the standard used for the design of
the equipment. Otherwise conformity to applicable requirements should be assessed and
verified, before the tests of this standard are performed.
This standard is also applicable to tests after REPAIR.
IEC 60601-1:2005 + IEC 60601-1:2005/AMD1:2012 requires that, as part of the RISK
MANAGEMENT PROCESS, the MANUFACTURER considers how the safety of ME EQUIPMENT or an
ME SYSTEM can be ensured during product lifetime. As part of the risk management process
the MANUFACTURER may have identified MAINTENANCE procedures. This includes defining the
respective tests for ME EQUIPMENT or for ME SYSTEM.
