Acceptance condition:
Table 7 – Test means for the tests for protection against solid foreign objects
Acceptance conditions for first characteristic numerals 3, 4:
The protection is satisfactory if the full diameter of the probe specified in table 7 does not pass through any opening.
NOTE:
For the first characteristic numerals 3 and 4 the probes specified in table 7 are intended to simulate foreign objects which may be spherical. Where an enclosure has an indirect or tortuous entry path and there is any doubt about ingress of a spherical obiect capable of motion, it may be necessary to examine drawinas or to provide special access for the object probe to be applied with the specified force to the opening(s) where ingress has to be checked.

FAQ:
How is IP3X Testing Completed?
To test for IP3X, a test probe with a diameter of 2.5mm is used to probe the enclosure for any openings or gaps that could allow solid objects to enter. The probe is applied with a force of 3N to any opening or gap that is likely to permit the entry of a solid object.
The test is performed on all accessible surfaces of the enclosure, including the sides, top, bottom, and any doors or panels. The test probe is applied to any joints, seams, or other areas where openings or gaps are likely to occur.
If the test probe does not enter the enclosure or only enters to a depth of less than 2.5mm, the enclosure can be rated as IP3X. If the test probe enters to a depth greater than 2.5mm, the enclosure cannot be rated as IP3X.
In addition to the test probe, the enclosure is also examined visually to ensure that there are no openings or gaps greater than 2.5mm in any direction. This inspection is typically performed with the naked eye under normal lighting conditions.
