purposes – Part 1: General requirements’ clause 12.2.5, figure 11

Standard description:
Terminals with screw clamping shall be so designed and constructed
that they clamp the conductor(s) without undue damage to the
conductor(s).
The terminal is placed in the test apparatus according to figure 11
and fitted with rigid, solid, stranded and/or flexible
conductor(s), according to table 3 first with the smallest and then
with the largest nominal cross-sectional area, the clamping
screw(s) or nut(s) being tightened with the torque according to
table 6.
Where rigid stranded conductors do not exist, the test may be made
with rigid solid conductors only. In this case, there is no need
for further tests.
The length of the test conductor shall be 75 mm longer than the
height (H) specified in table 9.
The end of the conductor is passed through an appropriate bushing
in a plate positioned at a height (H) below the equipment, as given
in table 9. The bushing is positioned in a horizontal plane such
that its centre line describes a circle of 75 mm diameter,
concentric with the centre of the clamping unit in the horizontal
plane; the platen is then rotated at a rate of (10 ± 2) r/min.
The distance between the mouth of the clamping unit and the upper
surface of the bushing shall be within ±15 mm of the height
specified in table 9. The bushing may be lubricated to prevent
binding, twisting, or rotation of the insulated conductor.
A mass as specified in table 9 is suspended from the end of the
conductor. The duration of the test is approximately 15 min.
During the test, the conductor shall neither slip out of the
clamping unit nor break near the clamping unit, nor shall the
conductor be damaged in such a way as to render it unfit for
further use. IEC Test Equipment
The test shall be repeated with rigid solid conductors where they
exist, if the first test has been made with rigid stranded
conductors.
