GB/T 4706.98-2024 Safety of household and similar electrical appliances - Part 98: Particular requirements for drives for gates, doors and windows
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This document deals with the safety of electric drives for horizontally and vertically moving gates, doors, garage doors and windows for household and similar purposes.
This document applies to electric drive devices for horizontal and vertical movement of gates, doors, garage doors, and windows for household and similar purposes, with a rated voltage of not more than 250 V for single-phase drives and 480 600 V for other drives.
Battery-operated drives and other d.c. supplied drives are within the scope of this standard. Dual supply drives, either mains-supplied or battery-operated, are regarded as battery- operated drives when operated in the battery mode.
Drives not intended for normal household use but which nevertheless may be a source of danger to the public, such as drives intended to be used by laymen in shops, offices, hotels, restaurants, hospitals, in industry and on farms, are within the scope of this standard.
Requirements for drives for doors that may be used in emergency routes and exits are given in Annex AA.
Note 101: Examples of drives within the scope of this standard are drives for
——folding doors;
——revolving doors;
——rolling doors;
——roof windows;
——sectional overhead doors;
——swinging and sliding gates or doors.
Examples are shown in Figure 101.
Note 102: Drives may be supplied with a driven part.
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.
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 labour and similar authorities.
Note 104: This standard does not apply to drives
——for vertically moving garage doors for residential use (60335-2-95);
——for shutters covering doors and windows (including locations where the door is set back from the shutter), awnings, blinds and similar equipment (60335-2-97);
——intended exclusively to be used by trained persons in commercial and industrial premises;
——for specific purposes, such as fire doors;
——for natural smoke exhaust ventilators not used as windows (ISO 21927-2);
——intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).
Note 105: This standard does not apply to movement of a pedestrian door where such movement is based solely on stored energy.

3 Terms and definitions
This clause of GB/T 4706.1-2024 is applicable except as follows.
3.1.9 Replacement:
normal operation
operation of the drive under the following conditions
Drives supplied without a driven part are operated with their rated load.
Drives supplied with a driven part are operated with the driven part installed in accordance with the instructions.
3.101
drive
motor and other components that control the movement of the driven part
Note: Examples of components are gears, controls, brakes, components for power transmission from the drive to the driven part and entrapment protection systems.
3.102
driven part
part of a gate, door, garage door or window that is intended to be moved by the drive
3.103
window
part in a building that opens and closes in order to regulate the air and light and that is not intended for passage
3.104
rated load
force or torque assigned to the drive by the manufacturer
3.105
rated operating time
duration of continuous operation assigned to the drive by the manufacturer
Note: During continuous operation, the drive may reverse its direction.
3.106
rated number of operating cycles
number of uninterrupted cycles assigned to the drive by the manufacturer
3.107
cycle
complete opening and closing movement of the driven part
Note: For revolving doors a cycle means the necessary rotation to allow a person to pass through it.
3.108
entrapment protection system
part of the drive that protects against crushing
Note 1: An entrapment protection system may consist of one or more devices, such as pressure sensitive edges, passive infrared and active light sensing devices, biased-off switches or motor current monitoring devices.
Note 2: An entrapment protection system may be incorporated in the motor assembly or installed separately.
3.109
biased-off switch
hold to run device that initiates and maintains the drive movement only as long as the manual control is actuated
3.110
automatic drive
drive that operates the driven part in at least one direction without intentional activation by the user
3.111
horizontally moving pedestrian door
swinging, sliding or rotating door designed for pedestrian use
3.112
reversible drive
drive that can be manually operated with or without power in both directions by manual action on the driven part
3.113
main closing edge
edge(s) of a pedestrian door leaf, whose distance from a parallel opposing closing edge or
surface determines the usable pathway
3.114
opposing closing edge
edge(s) of a pedestrian door leaf formed by the main closing edge and a fixed edge or a surface against which the pedestrian door leaf is moving
