Scope

This clause of GB 4706.1-2005 is replaced by the following.
This Part of GB 4706 deals with the safety of electric drives for rolling
equipment such as shutters, blinds and awnings, intended for household and
similar purposes, their rated voltage being not more than 250 V for
single-phase appliances and 480 V for other appliances.
Drives for equipment with a spring-controlled driven part, such as a folding
arm awning, are also within the scope of this Part.
NOTE 101 Examples of rolling equipment that can be driven are
- awnings;
- blinds;
- grilles covering doors and windows;
- projection screens;
- shutters covering doors and windows.
Examples are shown in Figure 101.
NOTE 102 Drives may be supplied with a driven part.
Appliances not intended for normal household use but that nevertheless may
be a source of danger to the public, such as appliances intended to be used
by laymen in shops, in light industry, on farms and on industrial premises, are
within the scope of this 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 playing with the appliance
by young children but recognizes that children may be in the vicinity.
driven part shall not unroll in an uncontrolled manner.
After 15 s, the driven part is retracted.
The drive is then supplied at 0.9 times rated voltage and started 10 times from
different positions in the rolling direction so as to retract the driven part. The
drive is allowed to come to rest between successive starts.
The drive shall retract the driven part to the fully rolled position each time and
protective devices shall not operate.
20.103 The actuation of a control to stop the unrolling movement shall be
effective. Compliance is checked by the following test.
The drive is supplied at rated voltage and operated under normal operation in
the unrolling direction and the control is then actuated.
The driven part shall not move more than 100 mm before stopping.
NOTE The release of a biased-off switch is deemed to be actuation.
20.104 Drives supplied with a driven part shall operate so that injury is
prevented during the unrolling movement.
This requirement is deemed to be met if the appliance is controlled by a fixed
biased-off switch only or if the driven part, when fully unrolled, is at a height of
at least 1.8 m.
For roller shutters fitted to a roof or ceiling window, compliance is checked by
inspection, by measurement or by the tests of 20.104.1, or 20.104.2 or
20.104.3. For other appliances, compliance is checked by inspection, by
measurement or by the tests of 20.104.1 or 20.104.2.
20.104.1 The appliance is supplied at rated voltage and operated under
normal operation in the unrolling direction. An obstacle is placed 400 mm
above the fully unrolled position.
The force exerted by the bottom edge of the driven part is measured.
The test is repeated with the obstacle placed 100 mm above the fully unrolled
position.
The force shall not exceed
- 25 N, for more than 5 s;
- 150 N, for more than 0.5 s.
NOTE Impact forces are not measured.
