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:
Model | SN2207-5J |
Impact energy(J) | 5 N.m, accuracy ±5% |
Combined mass | 1700g, accuracy ±2% |
Material | Stainless steel |
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%.
