Description

DoubleBollard grip for wire, yarns and threads. The sample is secured in a clamp and run around the two bollards. Grip stresses in the specimen are distributed uniformly around the bollard circumferences. Test method is similar to that described in BS4545:1970 (mechanical testing of steel wire)

Applications

Tensile testing of rope, flexible wire, cord, etc by straining a sample, generally to break, and recording the relationship between force and extension to determine one or more of the following mechanical properties:

Elongation	Stress
Percentage Elongation	Tensile Strength
Extension	Yield Strength
Percentage yield point extension	Yield Stress
Percentage reduction of area	Proof Stress
Maximum force	Youngs Modulus
