Pliability of Cables is determined by determining the force exerted by the cable specimen at a specified distance while bending to a specified degree or determining the degree of bend for exerting a specified force at a specified distance.
The Pliability Tester for Cables consists of digital balance fitted on a rigid base. One end of the cable under test is held in a rotating grip, while the other end is resting on a wedge on the balance at a distance of 76.2 mm (3”) from the rotating grip pivot. A pointer is attached to the grip and angle of movement of grip is indicated on a circular scale.
