IEC60245-2 Figure 1 Cable Testing Equipment Flexible Cables Flexing
TesterProduct information: This cable tester is designed and manufactured in accordance with
the standard requirement of IEC60245.2 clause 22.7. It is used for
checking mechanical strength of completed flexible cables. This
test does not apply to flexible cables with cores of nominal
cross-sectional area greater than 4mm2and cables having more than 18 cores laid up in more than two
concentric layers.
This cable tester consists of a carrier C (see IEC60245-2 Figure
1),a driving system for the carrier and four pulleys for each
sample of cable to be tested. The carrier C supports two pulleys A
and B, which are of the same diameter. The two fixed pulleys, at
either end of the apparatus, may be of a different diameter from
pulleys A and B, but all four pulleys shall be so arranged that the
sample is horizontal between them. The carrier makes cycles
(forward and backward movements) over a distance of 1 m at an
approximately constant speed of 0,33m/s between each reversal of
the direction of movement.
A sample of flexible cable about 5 m long shall be stretched over
the pulleys, each end being loaded with a weight. The mass of this
weight and the diameter of pulleys A and B are given in following
table.
