ASTM A931 is the test method for the tension testing of wire ropes and strand at room temperature. To match this to your program, talk with our team.
What ASTM A931 Covers
It defines how measured breaking force and related tensile properties are determined for wire rope and strand samples used in lifting, rigging, and structural work.
How the Test Is Run
A rope or strand sample with prepared end terminations is pulled to failure in a high-capacity machine, and the measured breaking force is recorded.
Why It Matters
Measured breaking force verifies rope and strand against required minimums; high-force capacity and sockets or fittings that develop full strength are essential.
