IEC62262:2002 Stainless Steel High Quality Spring Hammer Test Apparatus
Product information:
Standard: IEC62262:2002, IEC 60068-2-63, IEC 60068-2-75 test Ehb, 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.
This multi energy type has built-in 6 impact energies, can achieve 0.14J (IK01), 0.2J (IK02), 0.35J (IK03), 0.5J (IK04), 0.7J (IK05), 1J (IK06).
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-M |
Impact energy(J) | 0.14 and 0.2, 0.35, 0.5, 0.7, 1.0 |
Impact element mass | 250g±5g |
Overall mass | 1450g±10g |
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%.
