Product Description
Advanced Pendulum Impact Tester determines the energy required to break or rupture specimens of plastics or ceramics. The apparatus conforms to all of the international test standards including ASTM D256, ISO 179 and 180 for Izod, Charpy Testing , ASTM D1822 for Tension Impact Testing and other recognised standards.
The design utilises advanced dedicated microprocessor technology for simplicity, ease of operation, high accuracy and repeatability of results.
This apparatus is extremely versatile and allows impact velocities from 1.5 m/s up to 3.7 m/s combined with variable weight hammers to give an impact energy range up to 50 Joules. A special impact energy diagnostic programme has been included to assist the operator to select the correct size of Hammer for the Standard and material being tested.
The SCADA Software enables the Tester to be controlled via the PC. SCADA allows the use of recipes to upload frequently used test parameters and combine them with a operating strategy which ensure the procedures are correctly carried out. The test parameters and operating results can be displayed on screen, printed and/or archived as standard CSV files in which can be viewed or manipulated in Excel.
The apparatus also offers a Self Calibration procedure for bearing resistance and windage.
Standard features include
Advanced dedicated microprocessor control, Touch membrane Alpha / Numeric keypad for data entry, LCD display for sequence logic menu auto prompt selection, Yes / no mode selector, RS232 output with data transfer lead, Specview ?

Test Description
Izod Test
In this test the sample is notched and placed vertically in a vice with the notch positioned central to the top of the vice, facing the swing path of the pendulum. The pendulum, having a known energy, strikes the sample and the swing height of the pendulum after breaking the sample is measured and subtracted from the calibrated swing height. The result is the energy absorbed to break the sample.
Charpy Test
In this test the sample is placed on supporting rests, lengthways and at right angles to the swing path of the hammer. The test sample is usually notched mid way along its length and positioned so that the striking point of the pendulum hits the mid-point of the test sample opposite the notch. The pendulum, having a known energy, strikes the sample and the swing height of the pendulum after breaking the sample is measured and subtracted from the calibrated swing height. The result is the energy absorbed to break the sample.
Tension Impact Test
In this test the principle used is commonly called the ?specimen-in-bed method?. The test sample, usually in the shape of a tensile bar, is positioned in a horizontal plane with one end supported to the base of the apparatus on one end supported by a movable clamp. When the pendulum is released it strikes the movable clamp and breaks the test piece along its horizontal axis, thus applying a pure tensile load to the test sample.
Component test
The component test examines the influences of both the design and the manufacturing processes of a particular component by measuring the impact energy in Joules, required to break a complete or part of a section of a finished component. If a particular component has a critical cross sectional area that needs to be tested then by entering this area into the microprocessor the energy in KJ/M? can be obtained.
