Experimental :dust

Particle diameter distribution: < 1mm > 50um

Second eigenvalue

Protective experiment system of IPx6 for preventing Water intrusion

Experimental device: high pressure water

Experimental time: 1 hour

Experimental conditions for the second eigenvalue 7

Protective experiment system of IPx7 for preventing Water intrusion

Experimental device: intrusive pool

Distance: 1 m from top surface of chassis

Experimental time: 30 minutes

Definition of the first eigenvalue 6: no dust intrusion

Definition of the second eigenvalue 7: the amount of water that does not seep into the chassis for a specified period of time when the case is submerged in water at standard pressure
