Product Details

ISO 179-2 defines the method used to determine the resistance of plastic to breaking when impacted in a three point bend configuration, using a pendulum system with an appropriately sized, instrumented hammer arm. This test is used to characterize the materials behaviour under impact conditions. To this end, the instrumented hammer and Data Acquisition System collect relevant data in order to plot the force-deflection or force-time curve for the duration of the test. Different test parameters are specified according to the type of material that the specimen is made of as well as the type of notch cut in it. While similar to ASTM D6110 (Charpy Impact Resistance of Notched Plastic Specimens), the defined tests are significantly different and are not interchangeable.
