> IK codes :

Shock protection :  IK Code. It is a code system to indicate the cover required protection level against harmful mechanical impacts.

The IK code refers to the protection level. It is indicated as follows:
Each group of characteristic figures refers to the impact energy value, as indicated in the opposite table :

 CODE IK  00  01  02  03  04  05  06  07  08  09  10
 Shock energy (Joule)  0.15  0.20  0.35  0.50  0.70  1.00  2.00  5.00  10.00  20.00

 

> IP rating protection:

First number: protection degree against solid substances
Second number: protection against liquid substances

 IP 20  IP 40  IP 54 IP 65
