Shock Resistance

What is Shock Resistance?

Items have to be able to resist certain stress to be able to permanently function in a proper way. Many test laboratories use test facilities to check if components still function when mechanical stress is put on them. The testing conducted includes examination in regards to shock resistance. Due to environmental influences, shock and falling components can be stressed through shock and permanent shock. The overlapping of climate influences due to temperature and humidity may be required to test so it can be guaranteed that components are resistant to shocks in specific areas. A quick change in temperature may cause internal stress in a component which may change the shock resistance.

In the area of environment simulation, single shock test rigs which can create shocks with a force of up to a thousand times of that of the earth acceleration (1.000G). For the test of shock resistance the test machinery can create different types of shocks. These include half sinus, saw tooth or trapeze shocks. Details can be found in the standard regarding shock resistance (DIN EN 60068-2-27).

Areas of Application for Shock Resistant Devices

Proof of shock resistance qualifies components and devices of automation technology for use in the environment of presses and die cutters which create high stress on components. These forces cause shocks which are transported through the frame of the machine and the foundation and therefore may reach sensitive electric devices. In the area of plastic and wood processing machines which cause a shock type stress on the environment are used.
