IK07 IK08 IK09 IK10 Manual Release Vertical Impact Hammers
IK07/ IK08 / IK09 / IK10 Manual Release Vertical Impact Hammers
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. 2J striking element equip with Φ36mm*400mm guideway, 5J striking element equip with Φ61mm*300mm guideway, 10J striking element equip with Φ81mm*200mm guideway, 20J striking element equip with Φ101mm*400mm guideway, 50J striking element equip with Φ126mm*500mm guideway.
