This part of IEC 68-2 specifies test methods to determine the effects of dust and sand suspended in air, on electrotechnical products.
The test methods of this standard are not intended for the testing of air filters. Only method Lc2 is suitable for the simulation of the erosion effects of high velocity (more than 100 m/s) particles.
