IEC 60335-2-97 Ed. 4.0 b:2023 PDF

This clause of Part 1 is replaced by the following.

This part of IEC 60335 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, including direct current (DC) supplied appliances and battery-operated appliances.

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;
– draperies.

Examples are shown in Figure 101.

Drives can be supplied with a driven part.

Drives not intended for normal household use but that nevertheless can 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.

As far as is practicable, this standard deals with the common hazards presented by drives 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 drive safely without supervision or instruction;
– children playing with the drive.

For appliances 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 water supply authorities and similar authorities.

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 gates, doors and windows (IEC 60335-2-103);
– drives used in premises such as hangars or in heavy industry;
– drives for theatre curtains.
