How the IP4X Test Is Performed
During IP4X testing, the 1 mm Test Probe D is applied to all relevant openings of the enclosure using a force of 1 N.
The enclosure meets the IP4X requirement if the probe cannot access hazardous parts inside the enclosure during the test.
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 object capable of motion,
it may be necessary to examine drawings 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
What is an IP4X Test Probe D?
An IP4X Test Probe D is a standardized 1 mm access probe specified in IEC 60529 and IEC 61032, used to verify protection against access to hazardous parts.
What is the purpose of the 1N test force?
The 1 N test force ensures the test is performed under consistent and repeatable conditions, as required by IEC standards, when assessing access protection of electrical enclosures.
Which standards does this test probe comply with?
This test probe complies with IEC 60529 for IP codes and IEC 61032 for access probes, making it suitable for IP4X protection tests.
What types of equipment are tested using IP4X Test Probe D?
It is commonly used for testing electrical enclosures, control panels, switchgear, and household or similar electrical appliances requiring IP4X compliance.
Is IP4X Test Probe D the same as a finger probe?
No. IP4X Test Probe D is a 1 mm access probe and is different from finger probes (such as Probe A or B), which are used for other protection tests.
