TG23 Double Bollard Grip for Wire Yarns & Threads

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).

Tensile testing of rope, flexible wire, cord, etc by straining asample, 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
