The specimens commonly found suitable for powdermetallurgy materials are shown in Figs. 3 and 4. Powdermetallurgy impact test specimens shall be produced followingthe procedure in Practices B925. The impact test results ofthese materials are affected by specimen orientation. Therefore,unless otherwise specified, the position of the specimen in themachine shall be such that the pendulum will strike a surfacethat is parallel to the compacting direction. For powdermetallurgy materials the impact test results are reported asunnotched absorbed impact energy.
