IEC62262:2002 “Degrees of protection provided by enclosures for electrical equipment against external mechanical impacts (IK code) ”
 
Samples and Restrictions:
 
Household and similar electronic and electrical products and their accessories such as plugs and sockets and wall mounted mounting boxes, screw glands, covers, switches, luminaries, etc.
 
Application:
 
It is used for the impact resistance test of household and similar electronic and electrical products and their accessories such as plugs and sockets and wall mounted mounting boxes, screw glands, covers, switches, lamps, etc., to assess the safety performance and strength level of the products.

 
Test Principle:
 
Test Eha:Pendulum Hammer, the striking element is free released at a certain height through a 1 m pendulum tube,impact the specimen at the lowest point in the vertical direction, after the conversion of gravitational potential energy to kinetic energy, to achieve the purpose of impact test on the sample.
 
Structure:
 
The low energy pendulum impact test device is mounted to the wall, the sample mounting bracket is adjustable up, down, left and right, and the angle can be adjusted by pivot, thereby achieving impacts on different positions on the front side and impacts on side of the sample.
