The test shall be carried out by mieans 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.

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 fabout 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 as
given in Table 1.

restraining clamps D shall be fixed so that the pull
is always applied by the weight from which the
carrier is mowing away. The carrier shall make 30

be loaded with the current specified in Table 2.
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 short-
circuit between cores shall occur.

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.
