Medical electrical equipment - Recurrent test and test after repair of medical electrical equipment

IEC 62353:2014 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". 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/AMD1:2012. 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 the 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. This second edition cancels and replaces the first edition of IEC 62353 published in 2007. This edition constitutes a technical revision including the following main revisions: - 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; - revision of the protective earth resistance requirements for ME 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; - the inclusion of expected minimum insulation resistance values in Table 2; and - a reordering of the sequence of testing in Annex B.

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.

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

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.

MEDICAL ELECTRICAL EQUIPMENT –
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

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.
