IEC 60335-2-116:2019 deals with the safety of furniture with electrically motorized parts intended for household and similar purposes, their rated voltage being not more than 250 V.
Furniture incorporating electrically motorised parts not intended for normal household use but which nevertheless may be a source of danger to the public, such as furniture intended to be used by laymen in shops, offices, hotels, restaurants, cinemas, hospitals, schools, in light industry and on farms, are within the scope of this standard.
Examples of furniture incorporating electrically motorised parts, are
- electrically operated/height adjustable tables and desks;
- electrically operated/adjustable stands and wall attachment for e.g.TV sets and monitors;
- electrically operated/adjustable seating;
- beds with incorporated ventilators and filters;
- electrically operated/adjustable beds;
- electrically operated/adjustable storage units including kitchen units;
- electrically operated/adjustable furniture intended to be secured to the wall or ceiling;
- electrically operated extension elements (drawers and doors);
- electric check-out furniture in hotels and shops;
- furniture delivered in parts (ready to assemble or knock-down furniture).
This standard deals with the reasonably foreseeable hazards presented by furniture incorporating electrically motorised parts that are encountered by all persons. However, in general, it does not take into account
- persons whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the furniture incorporating electric appliances, parts or components safely without supervision or instruction;
- children playing with furniture incorporating electrically motorised parts.
Attention is drawn to the fact that
- for furniture incorporating electrically motorised parts 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 health authorities, the national authorities responsible for the protection of labour, the national authorities for fire protection and similar authorities.
This standard does not apply to
- furniture containing heating elements;
- electrically operated hospital beds (IEC 60601-2-52);
- electrical wheel chairs;
- special furniture incorporating electric appliances, parts or components, which are part of industrial production equipment;
- cupboards for building in appliances like a dishwasher;
- electric child care articles except electrical height adjustable changing (nursing) tables;
- furniture especially for use by children;
- furniture for outdoor use.
This standard only covers the risks associated with electrically motorized parts when operated as in normal use taking into account the manufacturer's instructions. It also covers abnormal situations that can be expected in practice and takes into account the way in which electromagnetic phenomena can affect the safe operation of such appliances. It does not cover risks associated with furniture containing heating elements.
Other safety aspects of furniture with and without electrically motorised parts are covered by the standards developed by ISO TC 136.
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fifth edition (2010) of that standard.
