What does the proof test load of an anchor chain demonstrate?

Correct Answer: Option D — Strength of the chain to a specified limit

Proof testing subjects anchor chain to a specific tension, typically 1.4 times the safe working load, to verify structural integrity and detect manufacturing defects. It ensures the chain can withstand expected operational stresses without permanent deformation, confirming it meets the classification society standards required by 46 CFR Subchapter F.
