Standard:
IEC 60335-1 Household and similar electrical appliances – Safety –
Part 1: General requirements clause 25.14, figure 8.
Standard description:
Appliances provided with a supply cord and that are moved while in
operation shall be constructed so that the supply cord is
adequately protected against excessive flexing where it enters the
appliance.
NOTE 1 This does not apply to appliances with automatic cord reels
that are tested by 22.1 6 instead.
Compliance is checked by the following test that is carried out on
an apparatus having an oscillating member as shown in Figure 8.
The part of the appliance that includes the inlet opening is fixed
to the oscillating member so that, when the supply cord is at the
middle of its travel, the axis of the cord where it enters the cord
guard or inlet is vertical and passes through the axis of
oscillation. The major axis of the section of flat cords shall be
parallel to the axis of oscillation.
The cord is loaded so that the force applied is
– 10 N, for cords having a nominal cross-sectional area exceeding
0,75 mm²;
– 5 N, for other cords.
The distance X, as shown in Figure 8, between the axis of
oscillation and the point where the cord or cord guard enters the
appliance, is adjusted so that when the oscillating member moves
over its full range, the cord and load make the minimum lateral
movement.
The oscillating member is moved through an angle of 90° (45° on
either side of the vertical), the number of flexings for type Z
attachments being 20 000 and for other attachments 10000. The rate
of flexing is 60 per minute.
NOTE 2 A flexing is one movement of 90°.
The cord and its associated parts are turned through an angle of
90° after half the number of flexings, unless a flat cord is
fitted.
During the test, the conductors are supplied at rated voltage and
loaded with the rated current of the appliance. Current is not
passed through the earthing conductor.
