Medical electrical equipment - Part 1: General requirements for basic safety and essential performance

Contains requirements concerning basic safety and essential performance that are generally applicable to medical electrical equipment. For certain types of medical electrical equipment, these requirements are either supplemented or modified by the special requirements of a collateral or particular standard. Where particular standards exist, this standard should not be used alone. The contents of the corrigenda of December 2006, of July 2007, the interpretation sheet 1 of April 2008, the interpretation sheet 2 of January 2009 and the interpretation sheet 2 of May 2013 have been included in this copy.

Medizinische elektrische Geräte - Teil 1: Allgemeine Festlegungen für die Sicherheit einschließlich der wesentlichen Leistungsmerkmale

Appareils électromédicaux - Partie 1: Exigences générales pour la sécurité de base et les performances essentielles

Contient les exigences concernant la sécurité de base et les performances essentielles qui sont généralement applicables aux appareils électromédicaux. Pour certains types d'appareil électromédicaux, ces exigences sont soit complétées soit modifiées par des exigences spécifiques données dans une norme collatérale ou une norme particulière. Lorsqu'il existe une norme particulière, il est recommandé de ne pas utiliser la présente norme générale seule. Le contenu des corrigendum de décembre 2006, de juillet 20007, la feuille d'interprétation 1 d'abril 2008, la feuille d'interprétation 2 de janvier 2009 et la feuille d'interprétation 3 de mai 2013 a été pris en considération dans cet exemplaire.

Medicinska električna oprema - 1. del: Splošne zahteve za osnovno varnost in bistvene zmogljivosti (IEC 60601-1:2005)

Ta mednarodni standard velja za OSNOVNO VARNOST in BISTVENE LASTNOSTI ELEKTRIČNE MEDICINSKE OPREME in ELEKTRIČNIH MEDICINSKIH SISTEMOV, v nadaljevanju ME OPREMA in ME SISTEMI. Če bo točka ali podtočka izrecno namenjena samo uporabi za ME OPREMO ali samo za ME SISTEME, bosta naslov in vsebina te točke ali podtočke to tudi navedla.Sicer točka in podtočka veljata za ustrezno ME OPREMO in ME SISTEME. NEVARNOSTI, ki so del fiziološkega delovanja ME opreme in ME SISTEMOV v okviru področja uporabe tega standarda, niso zajete s posebnimi zahtevami tega standarda, razen v točkah 7.2.13 in 8.4.1. Ta standard se lahko uporablja tudi za opremo, ki se uporablja za kompenziranje ali lajšanje bolezni, poškodbe ali prizadetosti. Diagnostična oprema in vitro, ki ni zajeta z definicijo ME OPREME, je zajeta s serijo 2 IEC 61010. Ta standard ne velja za vsadne dele aktivnih medicinskih vsadkov, ki so zajeti v ISO 14708-1. Ta EN 60601-1:2006 je bil v primerjavi z EN 60601-1:1990 precej preurejen. Zahteve v električnem delu so bile nadalje usklajene s tistimi za opremo informacijske opreme, ki jih zajema EN 60950-1, dodana je bila tudi zahteva za vključitev PROCESA ZA OBVLADOVANJE TVEGANJ. Za razširjen opis te revizije glej točko A.3.

Foreword

The text of document 62A/505A//FDIS, future edition 3 of IEC 60601-1, prepared by SC 62A, Common

aspects of electrical equipment used in medical practice, of IEC TC 62, Electrical equipment in

medical practice, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC

as EN 60601-1 on 2006-09-12.
The following date was fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-07-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-06-01
This European Standard supersedes EN 60601-1:1990 and its amendments.

This EN 60601-1:2006 has been significantly restructured compared to EN 60601-1:1990.

Requirements in the electrical section have been further aligned with those for information technology

equipment covered by EN 60950-1 and a requirement for including a RISK MANAGEMENT

PROCESS has been added. For an expanded description of this revision, see Clause A.3.

This European Standard has been prepared under a mandate given to CENELEC by the European

Commission and the European Free Trade Association and covers essential requirements of

EC Directives 90/385/EEC and 93/42/EEC. See Annex ZZ.
In this standard the following print types are used:
− requirements and definitions: in roman type;
− test specifications: in italic type;

− informative material appearing outside of tables, such as notes, examples and references: in smaller type. Normative text

of tables is also in a smaller type;

− TERMS USED THROUGHOUT THIS STANDARD THAT HAVE BEEN DEFINED IN CLAUSE 3 AND ALSO GIVEN IN

THE INDEX: IN SMALL CAPITALS.
In referring to the structure of this standard, the term

– “clause” means one of the seventeen numbered divisions within the table of contents, inclusive of

all subdivisions (e.g. Clause 7 includes subclauses 7.1, 7.2, etc.);

– “subclause” means a numbered subdivision of a clause (e.g. 7.1, 7.2 and 7.2.1 are all subclauses

of Clause 7).

References to clauses within this standard are preceded by the term “Clause” followed by the clause

number. References to subclauses within this standard are by number only. In this standard, the

conjunctive “or” is used as an “inclusive or” so a statement is true if any combination of the conditions

is true.

The verbal forms used in this standard conform to usage described in Annex G of the ISO/IEC

Directives, Part 2. For the purposes of this standard, the auxiliary verb:

− “shall” means that compliance with a requirement or a test is mandatory for compliance with this

standard;

− “should” means that compliance with a requirement or a test is recommended but is not

mandatory for compliance with this standard;

− “may” is used to describe a permissible way to achieve compliance with a requirement or test.
