Dust test


Dust-proof test grade, IP 1X: external foreign matters with a protection diameter ≥ 50mm shall enter. During the test, a rigid ball with a diameter of 50+0.05mm without handle and protection shall be pushed to any pore of the casing with a force of 50N + 10%. The rigid ball shall not completely enter the casing.

Dustproof test level

IP 1X: Protection against entry of foreign bodies with a diameter ≥ 50mm

During the test, use 50N + 10% force to push a rigid ball with a diameter of 50+0.05mm without handle and protection to any hole in the casing. The rigid ball shall not completely enter the casing.

IP 2X: Protection against entry of external foreign bodies with a diameter ≥ 12.5mm

During the test, use 30N + 10% force to push a rigid ball with a diameter of 12.5+0.2mm without handle and protection to any hole in the casing. The rigid ball shall not completely enter the casing.

IP 3X: Protection against entry of external foreign bodies with a diameter ≥ 2.5mm

During the test, use 3N + 10% force to push a rigid ball with a diameter of 2.5+0.05mm without handle and protection to any hole in the casing. The rigid ball shall not completely enter the casing.

IP 4X: Protection against entry of foreign bodies with a diameter ≥ 1mm

During the test, use 1N + 10% force to push a rigid ball with a diameter of 1+0.05mm without handle and protection to any hole in the casing, and the rigid ball shall not completely enter the casing.

IP 5X: Protection against certain dust, defined as not completely preventing dust from entering, but the amount of dust entering will not interfere with the normal operation of the equipment or affect the safety of the equipment.

Using sand and dust test chamber, use talcum powder (should be able to pass through the nominal line diameter of 50um, nominal spacing of 75um square hole filter) to simulate sand and dust, put the sample in the box to let the talcum powder freely fall to the sample surface. In the test, it should be ensured that there is 2KG of talcum powder in each cubic space, and the use of talcum powder does not exceed 20 times.

IP 6X can be described as completely dust-proof, any dust must not enter

Using sand and dust test chamber, use talcum powder (should be able to pass through the nominal line diameter of 50um, nominal spacing of 75um square filter) to simulate sand and dust, put the sample in the box to let the talcum powder freely fall to the sample surface. In the test, it should be ensured that there is 2KG of talcum powder in each cubic space, and the use of talcum powder does not exceed 20 times.
