“Subclause 9.1 of SS 236“:
9.1 Flexing test (except for tinsel cords, twisted
twin and single core cords). The test shall be
carried out by means of the apparatus shown in
Figure 5. This apparatus has a carrier C
supporting two pulleys A and B arranged so that
the cord is horizontal between the pulleys. The
carrier moves backward and forward over a
distance of 1 m at an approximately constant
speed of 0.33 m/s.
A sample of flexible cord about 5 m long shall
be stretched over the pulleys as shown in the
figure, each end being loaded with a weight.
The weight and the diameter of the pulleys A
and B shall be given in Table 1.
Screen cords in accordance with Table 7 shall be
tested before application of the screen and outer
sheath.
The pulleys shall have a semi-circular shaped
The pulleys shall have a semi-circular shaped
groove for circular cords and a flat groove for
parallel twin cords. The restraining clamps D shall
be fixed so that the pull is always applied by the
weight from which the carrier is moving away.
The carrier shall make 30 000 backward and
forward movements (60 000 single strokes). Each
conductor of the sample shall be loaded with the
current specified in Table 2.
For twin cords and for light PVC-sheated 3-core
For twin cords and for light PVC-sheated 3-core
cords, the voltage between the conductors shall
be approximately 230 V a.c. For all other cords
having three or more cores a three-phase a.c.
voltage of about 400 V shall be applied to three
conductors, any additional conductors being
connected to the neutral.
During the test no open-circuit in any core or
During the test no open-circuit in any core or
short-circuit between cores shall occur.
After the test, any sheath on cords having three
After the test, any sheath on cords having three
or more cores shall be removed. The cord, or the
laid up cores, shall then withstand the voltage test
specified in Subclause 8.2 or 8.3 as appropriate,
but with a test voltage not exceeding 2000 V.
