IK07 - IK10 Manual Release Vertical Impact Hammer
1. Introduction
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 Φ37mm*400mm guideway, 5J striking element equip with Φ64mm*300mm guideway, 10J striking element equip with Φ85mm*200mm guideway, 20J striking element equip with Φ104mm*400mm guideway, 50J striking element equip with Φ129mm*500mm guideway.
