The Free Falling Dart Impact Tester is used for PVC pipes, PVC ducting pipes & HDPE pipes as per IS & DOT specifications.

The impact properities of the polymetric materials are directly related to the overall toughness of the materual. Toughness is defined as the ability of the polymer to absorb applied energy. The area under the stress-strain curve isdirectly proportional to thetoughness of a material. Impact strength is a measurement of toughness. The higher the impact strength of a material the higher the toughness and vice-versa. Impact resistance is the ability of a material to resist breaking under a shock loading or the ability to resist the fracture under stress applied at high speed.
