description

The pendulum impact testing machine is a solid unit specially designed for engineering lectures. It is used for performing the notched bar impact bending test, one of the classic material tests. In this way, quality can be tested and the fracture behaviour of different metallic materials evaluated. The unit is equally suited for use with non-metallic specimens. The notched bar impact work necessary to deform the specimen can be read off directly from the gauge on a large scale. A two-hand trigger increases the safety for the user. A protective cover for the working area and a PC data acquisition is also available. The unit's basic data correspond to the requirements of DIN 50115. The educational advantages of the unit lie in its simple layout and direct visibility of all actions. Together with the other units in the WP range, this unit is part of a complete course on the fundamental principles of material testing.
