WebTwo of the most common methods are the so-called Izod and Charpy (pendulum) impact tests. 1 The Izod test is the more popular method for plastic materials whereas Charpy is very common for metals. The Izod 2 pendulum impact toughness test is described in the standard ASTM D256. This method requires a minimum of five and preferably ten or … WebOct 1, 2001 · Izod and Charpy tests are similar in many respects. Both use test specimens that are either molded to size or cut from a larger "dog-bone" tensile-test sample. Specimen size for Izod testing is 2.5 x 0.5 in., while Charpy uses 5 x 0.5 in. specimens. In both tests, sample thickness depends on the specifications for the material being tested ...
