Discard criteria: Local reduction of rope diameter
A reduction in the rope diameter in any part of the rope is an indication of internal or external wear or damage.
To accurately measure the diameter at any point of the rope, rotate the vernier caliper around the rope to record
the maximum dimension.
CAUTION
Standard or heavy-duty ropes shall be discarded when the actual diameter at
any point of the rope is 7% less than the nominal diameter. Rotation resistant
ropes shall be discarded when the actual diameter at any point of the rope is
3% less than the nominal diameter.
Discard criteria: Local increase of rope diameter
An increase in rope diameter in any part of the rope is an indication of deformation inside the rope.
CAUTION
Ropes shall be discarded when the actual diameter at any point of the rope is
5% more than the nominal diameter.
Discard criteria: Basket (birdcage) deformation
