ASTM A931 – Standard Test Method for Tension Testing of Wire Ropes and Strand

ASTM A931 – Steel Wire Tensile Testing

ASTM A931 covers the tension testing of wire ropes and strand at room temperature, specifically to determine the measured breaking force,

yield strength, elongation, and modulus of elasticity. Methods described in this standard are not intended for other purposes.

Geometry

Almost all steel strand and wire ropes are cylindrical, similar to a rope.

In some rare occasions that can be flat, in which case a wrap grip should be used instead of a rope grip.

Solution

Rope Grips are ideal for testing any stype of radial cordage.

The wire is wrapped around the drum several times and then tightened in the serrated jaw grip.
