Medical electrical equipment - Part 2-21: Particular requirements for the basic safety and essential performance of infant radiant warmers

IEC 60601-2-21:2009 specifies the safety requirements for infant radiant warmers. This particular standard amends and supplements IEC 60601-1:2005, Medical electrical equipment - Part 1: General requirements for basic safety and essential performance. This second edition cancels and replaces the first edition published in 1994 and its Amendment 1 (1996). This edition constitutes a technical revision. This edition of IEC 60601 2-21 was revised to structurally align with the 2005 edition of IEC 60601-1.

Appareils électromédicaux - Partie 2-21: Exigences particulières pour la sécurité de base et les performances essentielles des incubateurs radiants pour nouveau-nés

La CEI 60601-2-21:2009 spécifie les exigences de sécurité relatives aux incubateurs radiants pour nouveau-nés. La présente norme particulière modifie et complète la CEI 60601-1:2005, Appareils électromédicaux - Partie 1: Exigences générales pour la sécurité de base et les performances essentielles. Cette deuxième édition annule et remplace la première édition parue en 1994 et son Amendement 1 (1996). Cette édition constitue une révision technique. La présente édition de la CEI 60601 2-21 a été mise à jour de façon à correspondre structurellement à l'édition 2005 de la CEI 60601-1.

Medicinska električna oprema - 2-21. del: Posebne zahteve za osnovno varnost in bistvene lastnosti otroških sevalnih ogrevalnikov (IEC 60601-2-21:2009)

Ta mednarodni standard velja za OSNOVNO VARNOST in BISTVENE LASTNOSTI OTROŠKIH SEVALNIH OGREVALNIKOV, kot je določeno v 201.3.204 tega standarda, prav tako imenovanih ME OPREMA. 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 ali ME SISTEMOV v okviru uporabe tega standarda, niso zajete s posebnimi zahtevami tega standarda, razen v točkah 7.2.13 in 8.4.1 splošnega standarda. OPOMBA: Prav tako glej 4.2 splošnega standarda. Ta določen standard določa varnostne zahteve za OTROŠKE SEVALNE OGREVALNIKE, vendar alternativne metode skladnosti z določeno točko z dokazovanjem enakovredne varnosti ne bodo ocenjene kot neskladne, če je PROIZVAJALEC predstavil v svojem DOKUMENTU OBVLADOVANJA TVEGANJA, da je TVEGANJE, predstavljeno z NEVARNOSTJO, sprejemljive stopnje v primerjavi s koristjo terapije naprave. Ta konkretni standard ne velja za: - naprave, ki dovajajo toplote prek ODEJ, BLAZIN ali POSTELJNIH VLOŽKOV pri medicinski uporabi; za informacije, glej IEC 80601-2-35; - OTROŠKE INKUBATORJE; za informacije glej IEC 60601-2-19; - PRENOSNE INKUBATORJE; za informacije glej IEC 60601-2-20;
- OPREMO ZA FOTOTERAPIJO DOJENČKOV; za informacije glej IEC 60601-2-50.

Foreword
The text of document 62D/735/FDIS, future edition 2 of IEC 60601-2-21, prepared by SC 62D,
Electromedical 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 60601-2-21 on 2009-04-01.
This European Standard supersedes EN 60601-2-21:1994 + A1:1996.
EN 60601-2-21:1994 was revised to structurally align with EN 60601-1:2006.
The following dates were 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) 2010-01-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-04-01
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 Directive MDD (93/42/EEC). See Annex ZZ.
In this standard, the following print types are used:
– Requirements and definitions: roman type.
– Test specifications: 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 DEFINED IN CLAUSE 3 OF THE GENERAL STANDARD, IN THIS PARTICULAR STANDARD OR AS NOTED:
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 particular 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.

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 opinio
