The vertical impact hammer is designed according to IEC60068-2-75 test Ehc, the hammer consists by a striking element which falls freely from rest through a vertical height on to the specimen surface held in a horizontal plane, and the fall of the striking element shall be along a guideway, the guideway shall not rest on the specimen and the striking element shall be free of the guideway on the striking the specimen, the mass of striking element is equal to equivalent mass. 2J striking element equip with Φ40mm*471mm guideway, 5J striking element equip with Φ68mm*385mm guideway, 10J striking element equip with Φ89mm*337mm guideway, 20J striking element equip with Φ108mm*520mm guideway, 50J striking element equip with Φ129mm*650mm guideway.
What is ESD test? Electrostatic discharge immunity test is a basic EMC test . S tandard IEC61000-4-2 provide the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and to adjacent objects . T he standard establish a common and reproducible basis for evaluating the performance of electrical and electronic equipment when subjected to electrostatic discharges. Electrostatic discharge is a transfer of electric charge between bodies of different electrostatic potential in proximity or through direct contact. The standard IEC61000-4-2 does not intend to specify the tests to be applied to particular apparatus or system, it is to give a general basic reference to all concerned product . S o before conduct the test, an appropriate test level should be selected according to the product's characters and its working occasion. Contact discharge and air discharge methods The test leve...
