Wire Rope Discard Criteria
The precise discard criteria for the wire rope must be determined by a qualified
person while keeping in mind the characteristics of the application. As a rule of
thumb, any cable that shows one or more of the signs below should be replaced:
Wire Rope Discard Criteria
1
Six random broken wires over one cable lay or three broken wires in the
same strand over one cable lay
2
One broken wire close to an end fitting or a connector (bell fitting, spelter,
etc.)
3
One broken wire from the wire rope core which protrudes or loops out
from the wire rope structure
4
Sharp bends, crushed sections, bird cages or any other sign of damage
that results in severe distortion of the wire rope structure
5
Signs of heat damage (characteristic color change for example)
6
Reduction of the nominal diameter of 5% or more
