Household and similar electrical appliances - Safety - Part 2-96: Particular requirements for flexible sheet heating elements for room heating
IEC 60335-2-96:2019 deals with the safety of flexible sheet heating elements intended to be incorporated into floors and walls below 1,2 m and above 2,3 m and in ceilings, their rated voltage being not more than 250 V for single-phase installations and 480 V for other installations.
Flexible sheet heating elements are converted into heating units that are incorporated in the building in accordance with the instructions after which the required level of protection against hazards is achieved. Attention is drawn to the fact that:
– in many countries, different wiring rules apply;
– for heating units intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
– in many countries, additional requirements are specified by the national authorities for fire protection, the national authorities for building regulations, the national health authorities, the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to:
– heating units intended exclusively for industrial purposes;
– heating units intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
– blankets, pads, clothing and similar flexible heating appliances (IEC 60335-2-17);
– foot warmers and heating mats (IEC 60335-2-81);
– heated carpets and for heating units for room heating installed under removable floor coverings (IEC 60335-2-106);
– flexible sheet heating elements incorporated in other appliances.
This second edition cancels and replaces the first edition published in 2002, Amendment 1:2003 and Amendment 2: 2008. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the first edition:
– aligns the text with IEC 60335-1:2010, and its Amendments 1 and 2;
– some notes have been converted to normative text or deleted (5.6, 7.12.1, 10.1, 11.2.103, 13.1, 13.2, 16.2, 16.3, 18.101, 18.102.5, 21.1, 22.103, 22.105, 22.106);
– the strength test for heating units incorporating insulated wires intended to be installed in floors has been modified a (21.103);
– the scope and specific requirements have been added for heating units installed in walls below a height of 1,2 m (6.2, 7.1, 7.12.1, 7.12.6, 7.101, 11.2, 19.2, 22.106, 24.102, Annex AA).
Appareils électrodomestiques et analogues - Sécurité - Partie 2-96: Exigences particulières pour les films souples chauffants pour le chauffage des locaux
L'IEC 60335-2-96:2019 traite de la sécurité des films souples chauffants destinés à être intégrés aux planchers, aux murs au-dessous d'une hauteur de 1,2 m et au-dessus d'une hauteur de 2,3 m ainsi qu'aux plafonds, leur tension assignée ne dépassant pas 250 V pour les installations monophasées et 480 V pour les autres installations.
Les films souples chauffants sont convertis en unités chauffantes qui sont intégrées au bâti conformément aux instructions relatives à l'installation après laquelle le niveau de protection contre les dangers est atteint. L'attention est attirée sur le fait que:
– dans de nombreux pays, différentes règles de câblage s'appliquent;
– pour les unités chauffantes destinées à être utilisées dans des véhicules ou à bord de navires ou d'avions, des exigences supplémentaires peuvent être nécessaires;
– dans de nombreux pays, des exigences supplémentaires sont spécifiées par les organismes nationaux responsables de la protection anti-incendie, les organismes nationaux responsables de la réglementation des constructions, les autorités sanitaires nationales, les organismes nationaux en charge de la protection des travailleurs et des organismes analogues.
La présente norme ne s'applique pas:
– aux unités chauffantes prévues exclusivement pour des usages industriels;
– aux unités chauffantes destinées à être utilisées dans des locaux présentant des conditions particulières, telles que la présence d'une atmosphère corrosive ou explosive (poussière, vapeur ou gaz);
– aux couvertures, coussins, vêtements et appareils chauffants souples analogues (IEC 60335-2-17);
– aux chancelières et carpettes chauffantes électriques (IEC 60335-2-81);
– aux tapis chauffants et aux unités chauffantes pour le chauffage des locaux, installés sous des revêtements de sol amovibles (IEC 60335-2-106);
– aux films souples chauffants intégrés dans d'autres appareils.
Cette deuxième édition annule et remplace la première édition parue en 2002, l'Amendement 1:2003 et l'Amendement 2:2008. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à la première édition:
– mise en correspondance du texte avec l'IEC 60335-1, Ed 5, et ses Amendements 1 et 2;
– certaines notes ont été converties en texte normatif ou supprimées (5.6, 7.12.1, 10.1, 11.2.103, 13.1, 13.2, 16.2, 16.3, 18.101, 18.102.5, 21.1, 22.103, 22.105, 22.106);
– l'essai de rigidité diélectrique des unités chauffantes comprenant les câbles isolés destinés à être installés dans les planchers a été modifié (21.103);
– le domaine d'application et des exigences spécifiques ont été ajoutés pour les unités chauffantes installées dans les murs au-dessous d'une hauteur de 1,2 m (6.2, 7.1, 7.12.1, 7.12.6, 7.101, 11.2, 19.2, 22.106, 24.102, Annexe AA).

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
