Household and similar electrical appliances—Safety—Particular requirements for drives for gates, doors and windows
1 Scope
This clause of GB 4706.1-2005 is replaced by the following.
This part deals with the safety of electric drives for horizontally and vertically moving gates, doors and windows for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. It also covers the hazards associated with the movement of the driven part.
Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by laymen in shops, offices, hotels, restaurants, hospitals, in industry and on farms, are within the scope of this part.
Requirements for drives for doors that may be used in emergency exit are given in Annex AA.
Note 101: Examples of drives within the scope of this part are drives for
——folding doors;
——revolving doors;
——rolling doors;
——roof windows;
——sectional overhead doors;
——swinging and sliding gates or doors.
Examples of driven parts are shown in Figure 101.
Note 102: Drives may be supplied with a driven part.
As far as is practicable, this part 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
——the use of appliances by young children or infirm persons without supervision;
——playing with the appliance by young children.
Note 103: Attention is drawn to the fact that in many countries additional requirements are specified by the national authorities responsible for the protection of labor and similar authorities.
Note 104: This part does not apply to drives
——for vertically moving garage doors for residential use [GB 4706.68 (idt IEC 60335-2-95)];
——for rolling shutters for covering doors and windows (including those where doors are blocked by shutters), awnings, blinds and similar equipment (IEC 60335-2-97);
——for horizontally moving pedestrian doors with an opening width greater than 3m and an opening area greater than 6.25 m2;
——intended exclusively to be used by trained persons in commercial and industrial premises;
——for special purposes, such as fire barriers;
——intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapor or gas).
Note 105: This part does not apply to the movement of pedestrian doors that rely solely on stored energy for movement.
