ISO 3108 Steel Wire Ropes — Determination of Measured Breaking Force

← Back to all standards

ISO 3108 is the test method for determining the measured (actual) breaking force of a steel wire rope by tensile testing to destruction. To match this to your program, talk with our team.

What ISO 3108 Covers

It defines how a wire rope is pulled to failure to verify its performance against required minimum breaking-force values in rope requirement documents.

How the Test Is Run

A wire rope with prepared end terminations is pulled to destruction in a high-capacity machine, and the measured breaking force is recorded.

Why It Matters

Because breaking tests depend heavily on end terminations, correct socketing and high-force capacity are essential to a valid result.
