ä  New Testing Machines: Impact Test Machine Model IMP.2011 The model 2011 is ideal for tests on thin section or brittle plastics, composites, ceramics and metals. Designed to meet the need for a small mass drop weight impact test machine with a range of adjustable energies and velocities. The crosshead weight is variable from approximately 7 to 50 lbs., the impact energy is variable up to approximately 150 ft/lbs and the impact velocity is variable up to approximately 14 ft/sec. This machine allows for a wide range of test configurations so both specimens and actual components can be tested.
