IEC 60068-2-75 Spring Impact Hammer Tester 5J Of IK08 For Impact Resistance Testing

Product information:

The spring hammer tester conforms to IEC 60068-2-63, IEC 60068-2-75 test Ehb, and required by IEC 60335-1 clause 21.1, IEC 60598-1, IEC 60950, IEC 60065, etc.

Application: This device is intended to test the impact resistance to shell, 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.

Test sample: Shell, operating arm, handle, knob, indicator lights and shades

Feature:

1. The impact hammer is composed of three parts:

A. Shell. Includes housing, impact element guide and release mechanism, and parts fixed on these parts.

B. Impact element. Including the hammer, hammer tail and firing handle.

C. Release cone.

2. Working principle

The hammer generates 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.

Technical parameters:

Notice:

1. After calibrating the device, don’t disassemble it or adjust the compression amount of the spring.

2. If the compression amount of the springs is adjusted, the device must be checked by the measurement department before being used. Otherwise, the accuracy of testing results will be directly influenced.

3. In order to prevent changes of impact energy caused by misoperation, the products have been sealed in the factory. If you have any question, please contact our factory, we will provide you post-technical services.

4. Measures should be taken to prevent the rust of the hammer spring (drying moisture proof processing).

5. Requirements for environmental conditions: temperature 5~35℃, humidity 45 ~ 75%.
