Household and similar electrical appliances - Safety - Part 2-97: Particular requirements for drives for shutters, awnings, blinds and similar equipment
IEC 60335-2-97:2016 deals with the safety of electric drives for shutters, blinds and awnings, intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase drives and 480 V for other drives. Battery-operated drives and other d.c. supplied drives are within the scope of this standard. Examples of equipment that can be driven are:
- spring controlled folding arm awnings;
- curtains;
- grilles covering doors and windows;
- projection screens;
- shutters covering doors and windows and draperies. Drives may be supplied with a driven part. Drives not intended for normal household use but that nevertheless may be a source of danger to the public, such as drives intended to be used by laymen in shops, in light industry, on farms and on industrial premises, are within the scope of this standard. Attention is drawn to the fact that for drives intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary. This standard does not apply to
- drives intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
- drives for vertically moving garage doors for residential use (IEC 60335-2-95);
- drives for rolling doors (IEC 60335-2-103);
- drives used in premises such as hangars or in heavy industry and drives for theatre curtains. As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account:
- persons (including children) whose physical, sensory or mental capabilities or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction or
- children playing with the appliance. This third edition cancels and replaces the second edition published in 2002 including its Amendment 1 (2004) and its Amendment 2 (2008). It constitutes a technical revision. The principal changes in this edition as compared with the second edition of IEC 60335-2-97 are as follows (minor changes are not listed):
- Deleted "rolling" from the title and modified the scope to cover appliance types other than shutters, awnings, and blinds that are operated in a rolling way;
- Revised 19.13 to allow drives to obtain a safe position;
- Added 19.101 to provide a new abnormal test for drives with rated operating time;
- Added 20.104.4 to establish a test intended to cover horizontal movement (non-rolling) drive parts;
- Added 20.104.5 to provide an additional test to cover rolling grills to address the risk of being lifted;
- Modified 22.46 and Annex R to introduce software requirements for programmable electronic circuits used to comply with Clause 20;
- Added 22.101 to introduce a requirement to prevent inadvertent adjustments that would lead to unsafe application of drives;
- Added examples of swing shutters and sliding shutters in Figure 101. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselves for conducting new or revised tests. It is the recommendation of the committee that the content of this standard be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication. Key words: Electric Drives, Shutters, Awnings, Blinds, Driven Part
This publication is to be read in conjunction with IEC 60335-1:2010.
Appareils électrodomestiques et analogues - Sécurité - Partie 2-97: Exigences particulières pour les motorisations de volets, stores, rideaux et équipements analogues
IEC 60335-2-97:2016 traite de la sécurité des motorisations électriques pour les volets, les rideaux et les stores pour usages domestiques et analogues dont la tension assignée n'est pas supérieure à 250 V pour les motorisations monophasées et 480 V pour les autres motorisations. Les motorisations alimentées par des batteries et les autres motorisations alimentées en courant continu font partie du domaine d'application de la présente norme. Des exemples d'équipements qui peuvent être motorisés sont:
- les stores bannes à ressorts;
- les rideaux;
- les grilles qui protègent les portes et les fenêtres;
- les écrans de projection;
- les volets qui protègent les portes et les fenêtres et les draperies. Les motorisations peuvent être fournies avec une partie entraînée. Les motorisations qui ne sont pas destinées à un usage domestique normal mais qui néanmoins peuvent constituer une source de danger pour le public, telles que les motorisations destinées à être utilisées par des utilisateurs non avertis dans des magasins, chez des artisans, dans des fermes et dans des locaux industriels, sont comprises dans le domaine d'application de la présente norme. L'attention est attirée sur le fait que pour les motorisations destinées à être utilisées dans des véhicules ou à bord de navires ou d'avions, des exigences supplémentaires peuvent être nécessaires. La présente norme ne s'applique pas
- aux motorisations 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 motorisations de portes de garage à ouverture verticale pour usage résidentiel (IEC 60335-2-95);
- aux motorisations de portes à enroulement (IEC 60335-2-103);
- aux motorisations utilisées dans des locaux tels que les hangars d'avions ou dans l'industrie lourde ou aux motorisations pour rideaux de théâtres. Dans la mesure du possible, la présente norme traite des risques ordinaires présentés par les motorisations, encourus par toutes les personnes à l'intérieur et autour de l'habitation. Cependant, cette norme ne tient pas compte en général
- des personnes (y compris des enfants) dont les capacités physiques, sensorielles ou mentales;
- ou le manque d'expérience et de connaissance les empêchent d'utiliser la motorisation en toute sécurité sans surveillance ou instruction. Cette troisième édition annule et remplace la deuxième édition parue en 2002, son Amendement 1 (2004) et son Amendement 2 (2008). Elle constitue une révision technique. Par rapport à la deuxième édition de l'IEC 60335-2-97, les principales modifications indiquées ci-après ont été apportées (les modifications mineures ne sont pas mentionnées):
- Suppression de l'adjectif "enroulables" dans le titre et modification du domaine d'application pour couvrir des types d'appareils autres que les volets, les stores et les rideaux qui sont ouverts et fermés par enroulement;
- Révision de 19.13 pour permettre aux motorisations d'atteindre une position sûre;
- Ajout de 19.101 pour fournir un nouvel essai de fonctionnement anormal pour les motorisations ayant une durée de fonctionnement assignée;
- Ajout de 20.104.4 pour établir un essai destiné à couvrir les parties de motorisation (non enroulables) à mouvement horizontal;
- Ajout de 20.104.5 pour fournir un essai supplémentaire pour couvrir les grilles enroulables dans le but de traiter le risque d'être soulevé;
- Modification de 22.46 et de l'Annexe R pour introduire des exigences logicielles pour les circuits électroniques programmables utilisés pour satisfaire à l'Article 20;
- Ajout de 22.101 pour introduire une exigence destinée à empêcher les réglages involontaires de nature à conduire à une application des motorisations n'assurant pas la sécurité;
- Ajout d'exemples de volets battants et de volets roulants à la Figure 101. L'attention des Comités Nationaux est attirée sur le fait que les fabricants d'appareils et les organis
