    Abstract

    The instrumented impact test with Charpy specimens of subsize geometry is discussed in relation to equivalent standard procedures for performing the test with specimens of regular size. Subsize specimens because of their smaller dimensions imply smaller load values and higher frequencies of the force oscillations. These differences in the behaviour require special high sensitivity striker tups, force measuring chains of high upper frequency bounds, and knowledge of the actual Hooke's line for determining the yield force Fgy. Practical recommendations are given and procedures are outlined on how these requirements can be met and how the evaluations can be performed. The applicability of the presented measuring and evaluation procedures and the validity and the accuracy of the obtained data is demonstrated by experimental results.
