Advanced Universal Pendulum Impact System
Order Code : RR2500
Izod Impact
Charpy Impact
Tension Puncture Impact

Product Overview

A highly accurate universal pendulum impact tester, designed in accordance with all International test standards for Izod, Charpy, Tension and Puncture impact testing of samples and components. The design utilises advanced dedicated microprocessor technology for ergonomic simplicity, ease of operation, high accuracy and repeatability of test results.

This apparatus has an energy range up to 25 Joules and infinitely variable velocity from 1.5 m/s to 3.8 m/s.

Supplied as standard with built-in test results printer, RS232 output and WindowsTM data link PC software, all included in the basic cost of the apparatus.

With the additional puncture impact feature, the system's advanced microprocessor records factual puncture test results as opposed to the traditional "drop dart" method. Welcome to the future in puncture impact testing.

Puncture Impact Feature


The apparatus is extremely versatile. Impact velocities up to 3.7 m/s combined with variable weight pendulum hammers give an impact energy range of up to 25 Joules. WindowsTM data link PC software provides a special impact energy diagnostic program to assist the operator to select the correct size of pendulum hammer for the material being tested. The test sample takes the form of a circular clamped ring and thus eliminates any possible influence on the test results of the way the sample is cut out.


Determining the most cost effective packaging material specification for a particular application can be a daunting proposition if reliable information is not available on the material behavior under different load conditions. The impact strength can be crucial if the handling of the package cannot be controlled, especially if objects with sharp profiles are to be packaged.

Hitherto, the principal method of evaluating the impact strength of thin ductile packaging materials has been with a drop dart tester. But in recent years, many companies have questioned the accuracy, reliability and repeatability of the data obtained using this method. In the main, this is because the degree of the material failure is so subjective to operator interpretation and non-failures must also be accounted for in calculating the results. Also, the absence of instrumentation providing immediate test results is a distinct disadvantage.

The puncture impact feature for the Ray-Ran Advanced Universal Pendulum Impact System has addressed all of these problems and produced a test method that is accurate, reliable and immediately displays and prints the test result using a microprocessor control. Test results can safely be compares between different test centres. Therefore, an International organisation can set material standards world-wide knowing that consistent quality control is assured.


The impact system can examine the material behavior in a combination of different ways. By using different tup strikers, the mode of failure can be analysed to represent direct comparisons with other materials and hence produce an in-house, or to simulate actual service conditions.

For instance, if impact elongation properties are required for ductile material, then a large spherical radius tup striker is used to induce a high degree of lateral elongation of the material before the tup striker can penetrate through the material to the point of failure. If, however, a more brittle failure (minimum elongation of the material), a more pointed tup striker is employed. If required, the tup striker can simulate the actual object to be packaged to see how the packaging material would stand up to poor handling in service.
