Falling Dart Impact

Deepak Free Falling Dart Impact Tester is used for PVC pipes, PVC ducting pipes & HDPE pipe as per IS, DIN, ASTM, BS, DOT specifications.

The impact properties of the polymeric materials are directly related to the overall toughness is defined as the ability of the polymer to absorb applied energy. The area under the stress-strain curve is directly proportional to the toughness 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.

The pipe shall be placed on 'v' block in a such way that one of the marked lines is upper most. The stricker shall be allowed to fall manually/chain drive motorized system.

Specimens: 200 ± 10 mm long pipe shall be cut from the complete section. Each specimen shall be cut clean & gauge to the axis of the pipe.

• Drop height up to 2 mtrs.
• Drop height controlled manually/motorised.
• Pipe diameter can be tested up to 315 mm in manual version, where as up to 450/630 mm in motorised version.
• Falling weight: 250 gms, 500 gms, 1 kg, 10 kg or as per the requirement of various standards.
