This test device meets the standard of IEC 60068-2-75 Test Ehb, Clause 6, Figure E:1.
This device is intended to test the impact resistance to enclosure, operating arm, handle, knob, indicator lights and shades of electrical appliance for household or similar purpose, to verify the safety performance and strength of the product.
Relevant Standards: Series of IEC 60065, IEC 60335, IEC 60598, IEC 60601, IEC 61010 and similar.
X is the impact energy of each model.( MT-SH-0.14: 0.14 J )
– The impact hammer is composed of three parts:
- Shell. Includes housing, impact element guide and release mechanism, and parts fixed on thes parts.
- Impact element. Including the hammer, hammer tail and firing handle.
- Release cone.
– Working principle
The hammer generate impact energy by the mass and movement of impact element. When pulling the operating handle, release claw stop at the impact element release point, the hammer spring is pressed, when the compression quantity is different, the spring will release the different energy. For multi energy impact hammer, rotate the end cover to select corresponding impact energy. The impact energy was calibrated on calibration facility before delivery.
