Medical electrical equipment - Part 2-33: Particular requirements for the basic safety and essential performance of magnetic resonance equipment for medical diagnosis (IEC 60601-2-33:2010)
This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of MR EQUIPMENT and MR SYSTEMS, hereafter referred to also as ME EQUIPMENT. This standard does not cover the application of MR EQUIPMENT beyond the INTENDED USE. If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME EQUIPMENT and to ME SYSTEMS, as relevant.

La CEI 60601-2-33:2010 établit des exigences particulières relatives à la sécurité de base et aux performances essentielles pour les appareils à résonance magnétique en matière de protection pour le patient et le personnel pour la résonance magnétique. Cette troisième édition annule et remplace la deuxième édition parue en 2002, son Amendement 1 (2005) et son Amendement 2 (2007), et constitue une révision technique. Cette troisième édition de la CEI 60601-2-33 est basée sur le deuxième amendement de l'Edition 2. Elle a également été adaptée à la troisième édition de la CEI 60601-1 (2005), des modifications techniques ayant été introduites le cas échéant.
Medicinska električna oprema - 2-33. del: Posebne zahteve za varnost opreme za magnetno resonanco za medicinsko diagnostiko (IEC 60601-2-33:2010)
Ta mednarodni standard velja za OSNOVNO VARNOST in BISTVENE LASTNOSTI MR OPREME in MR SISTEMOV, v nadaljevanju ME OPREME. Ta standard ne zajema uporabo MR OPREME zunaj PREDVIDENE UPORABE. Če je klavzula ali podklavzula izrecno namenjena samo za uporabo za ME OPREMO ali samo za ME SISTEME, bosta naslov in vsebina te klavzule ali podklavzule to tudi navedla. V nasprotnem primeru tako klavzula ali podklavzula veljata za ustrezno ME OPREMO in ME SISTEME.

This European Standard was approved by CENELEC on 2010-10-01. CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.
Foreword The text of document 62B/777/FDIS, future edition 3 of IEC 60601-2-33, prepared by SC 62B, Diagnostic imaging equipment, of IEC TC 62, Electrical equipment in medical practice, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60601-2-33 on 2010-10-01.
