Ray-Ran - Advanced Universal Pendulum Impact Tester

The Ray-Ran Advanced Universal Pendulum Impact Tester utilises advanced microprocessor technology to determine the energy required to break or rupture specimens such as plastics, composites, ceramics and non ferrous metals to International testing methods for Izod, Charpy and Tension Impact Testing.

To calculate the impact energy, the apparatus uses advanced and highly accurate rotary encoder technology to record the lost angle of the hammer after impacting a test sample against the angle recorded after calibrating the hammer. The resulting lost angle is calculated as the test sample’s impact energy by the advanced microprocessor system.

The apparatus is supplied as standard with Ray-Ran’s Techni-Test Windows based PC software for connection to the apparatus via an RS232 or Ethernet connection. Test results can be printed directly from the Techni-Test software or can be saved and exported as .CSV files which can be opened with Microsoft Excel in tabular form which can be manipulated to your specific requirements such as preparing a graphical presentation or copying the results to a Word document for a report presentation if required.

Testing Methods Available

For the Izod test, the specimen is supported and impacted in a cantilevered position with one end of the specimen clamped into the vice. A single swing of the impact hammer is required to break the specimen and the subsequent impact strength calculated. Notched or Un-notched specimens can be tested using the Izod method. Complies to International Test Standards ASTM D256, ASTM D4812 and ISO 180. Impact hammer energies are available from 0.5 J up to 25 J

The Charpy test requires a standard notched or un-notched test specimen to be supported as a horizontal beam and is impacted on either its narrow face or the width of its cross-section. A single swing of the impact hammer is required to break the specimen and the subsequent impact strength calculated. Complies to International Test Standards ISO 179, ASTM D256, ASTM D6110, DIN 53453, DIN 53753, and BS 7413. Impact hammer energies are available from 0.5 J up to 50 J

Tensile impact tests are conducted on material samples that are either too thin or exhibit a high elongation before fracture. 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 and the other 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. Complies to International Test Standard ISO 8256 Method A. Impact hammer energies are available from 0.5 J up to 50 J

The test is used for the examination of pipe sections and tubing for impact strength properties as either complete segments or small sections of pipes. Sample diameter dimensions up to 25 mm can be tested with hammer energies of 7.5 - 15 J. The test specimen is supported as a horizontal beam similar to Charpy tests conditions and complies to International Test Standards ISO 7628 and ISO 9854. Sample diameter dimensions up to 25 mm (0.98 in) can be tested with hammer energies of 7.5 - 15 J (5.6 - 11.1 ft-lbs) or 50 J (36.9 ft-lbs), as defined in the ISO standards.

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/M² can be obtained.
