Safety of household and similar electrical appliances - Part 68: Particular requirements for drives for vertically moving garage doors for residential use
Safety of household and similar electrical appliances - Part 68 : Particular requirements for drives for vertically moving garage doors for residential use
1 Scope
This clause of GB/T 4706.1- 2024 is replaced by the following.
This standard deals with the safety of electric drives for garage doors for residential use that open and close in a vertical direction
This standard applies to the rated voltage of electric drives 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 these electrically driven garage doors.
Note 101: Examples of garage doors are shown in Figure 101.
Note 102: The drive can be supplied with a garage door.
Note 103: This standard also applies to entrapment protection devices for use with drives. It does not cover hazards related to the mechanisms of the door itself.
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 playing with the appliance by young children, but recognizes that children may be in the vicinity of the garage door.
Note 104: Attention is drawn to the fact that in many countries additional requirements are specified by the national authorities concerned.
Note 105: This standard does not apply to drives
– for shutters, awnings, blinds and similar equipment (GB/T 4706.101);
– for gates, doors and windows (GB/T 4706.98);
– for commercial and industrial purposes;
– intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas).

4 General requirement
This clause of GB/T 4607.1-2024 is applicable.
5 General conditions for the tests
This clause of GB/T 4607.1-2024 is applicable except as follows.
5.2 Addition:
When a test has to be carried out with a door, the door specified for installation with the drive that gives the most unfavourable conditions for the test is used. An artificial load may be used to simulate the door for some of the tests. The drive is adjusted in accordance with the instructions.
5.5 Addition:
Wicket doors are kept closed during the tests.
6 Classification
This clause of GB/T 4607.1-2024 is applicable except as follows.
6.1 Modification:
Drives shall be class I, class II or class III.
6.2 Addition:
Drives intended to be exposed to outdoor conditions shall be at least IPX4.
7 Marking and instructions
This clause of GB/T 4607.1-2024 is applicable except as follows.
7.1 Modification:
Drives shall be marked with the rated power input.
Addition:
Drives supplied without a door shall be marked with the rated load in N or in Nm.
7.12 Addition:
The instructions shall state the substance of the following:
WARNING: Important safety instructions. It is important for the safety of persons to follow all instructions. Save these instructions.
The instructions shall include the substance of the following:
– do not allow children to play with door controls. Keep remote controls away from children;
– watch the moving door and keep people away until the door is completely opened or closed (not necessary for automatic drives);
– take care when operating the manual release since an open door may fall rapidly due to weak or broken springs, or being out of balance;
– frequently examine the installation, in particular check cables, springs and mountings for signs of wear, damage or imbalance. Do not use if repair or adjustment is needed since a fault in the installation or an incorrectly balanced door may cause injury;
– each month check that the drive reverses when the door contacts a 40 mm high object placed on the floor. Adjust if necessary and recheck since an incorrect adjustment may present a hazard;
– disconnect the supply when cleaning or carrying out other maintenance.
The instructions shall include the following information:
– details on how to use the manual release;
– information concerning the adjustment of the door and drive (when applicable).
Instructions for automatic drives shall state the substance of the following:
WARNING: Automatic door – The door may operate unexpectedly, therefore do not allow anything to stay in the path of the door.
