IEC 60335-2-97 Ed. 3.1 b:2019

IEC 60335-2-97:2019 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.
