Pendulum Impact Testing Machine 7.5J Charpy impact test ASTM D256 PIT501J

Pendulum Impact Testing Machine 7.5J Charpy impact test ASTM D256 PIT501J


Functions

PIT501J can be equipped with 1J, 2J, 4J, 7.5J, 15J, 25J and 50J pendulum to perform Charpy impact tests, complying with ISO 179.


ASTM D256 Standard Test Methods for Determining the Izod Pendulum Impact Resistance of Plastics.

5. Significance and Use 5.1 Before proceeding with these test methods, reference should be made to the specification of the material being tested. Any test specimen preparation, conditioning, dimensions, and testing parameters covered in the materials specification shall take precedence over those mentioned in these test methods. If
there is no material specification, then the default conditions apply.
5.2 The pendulum impact test indicates the energy to break standard test specimens of specified size under stipulated parameters of specimen mounting, notching, and pendulum velocity-at-impact.

5.3 The energy lost by the pendulum during the breakage of the specimen is the sum of the following:
5.3.1 Energy to initiate fracture of the specimen;
5.3.2 Energy to propagate the fracture across the specimen;
5.3.3 Energy to throw the free end (or ends) of the broken specimen (“toss correction”);
5.3.4 Energy to bend the specimen;
5.3.5 Energy to produce vibration in the pendulum arm;
5.3.6 Energy to produce vibration or horizontal movement of the machine frame or base;
5.3.7 Energy to overcome friction in the pendulum bearing and in the indicating mechanism, and to overcome windage (pendulum air drag);
5.3.8 Energy to indent or deform plastically the specimen at the line of impact; and
5.3.9 Energy to overcome the friction caused by the rubbing of the striker (or other part of the pendulum) over the face of the bent specimen.


Features

High resolution

Using a shaftless encoder allows angle resolution of 0.045 °


Energy losses

Shaftless encoder for angle measurement rotates without any friction; only support bearings friction and windage has the lowest energy losses


LCD display

LCD display provides easy setup of specimen dimensions, pendulum energy, units and calibration data. Also it can intuitionally display test results: absorbed energy and impact toughness


Exchangeable pendulum

Simply change the pendulum to satisfy Charpy, Izod and tensile impact test


Center alignment

Rotating design is quick and accurate to align specimen center for Charpy test


Supports and anvils

Supports are tightened to seat by dovetail groove firmly; only need remove two bolts to change the supports


Broader test space

Single column structure offers broad test space, easy to install low temperature impact test accessories in the future
