Pussegoda, A. Fredj, A. Impactek data acquisition system is available to be introduced into DWTT tester, through which can upgrade simple uninstrumented DWTT tester to an instrumented DWTT tester who is able to measure the amount of force required to break a specimen, and this enables calculation of separate values for initiation energy and propagation energy, those impact resistance information gathered by doing instrumented testing can be used by Research and Development to evaluate the effects of metallurgical variables such as composition, processing, heat treatment can have on the fracture resistance of new or existing materials.

A specimen supported at both ends is impacted with a cold-press-fitted notch, with the point of impact opposite the notch. Since the specimen thicknesses are very large sections of actual pipeline tubes, high impact energies of up to , Joule are necessary to break the specimen. Main features 1.

Regulating impact energy by adjusting the lifting height and mass of the weights. Key Advantages and Features Description In the test, weights fall on to a specimen supported at both ends and break it.

The specimen is provided with a cold-pressed notch, this being the point at which it breaks under the impact effect. DWT drop weight testers are available in the following energies: 20, 30, 40, 60, 80 and KJ The standard maximum drop-height for all sizes is 5m.

DWT 20 - 40 are alternatively available with a maximum drop-height of 2. Pneumatic specimen feed and fixture loading outside the test area guarantees fast, reliable feeding within the time required by the standard.
