•
Do they test a sample from each production length to destruction?
• On what basis is the minimum breaking force specified?
Is it a calculated value which is not verified?
• Is the specified minimum breaking force an aggregate
value based on the strength of the wires going into the rope before
ropemaking or taken from the rope after ropemaking?

| BRIDON
tests a sample of rope from each production length to destruction
for all lifting ropes as designated by the actual breaking force
stated on the certificate. This gives the user confirmation that
the rope has met or exceeded its specified minimum breaking force
value. See tables for which ropes are tested by designation of Powerchecked.
