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 |
