3mm Cylindrical Steel Test Tod Used For Electrical Safety Testing
IEC 60884 : 2022
Product Overview:
The 3mm test rod conforms to the IEC 60884-1:2013 clause 24.11
requirement.
A cylindrical steel rod, having a diameter of 3 mm and a
hemispherical end with a radius of 1,5 mm, is pushed perpendicular
to the supporting mounting surface, in the most unfavourable
position, for 10 s against the barrier, the force being equal to
1,5 times the maximum plug withdrawal force.
Feature:
The "3mm test rod" refers to a specific test probe used for
electrical safety testing, particularly in the context of
electrical plugs, sockets, and similar devices. It is commonly used
to assess the clearance and creepage distances in accordance with
various standards, including IEC 60884.
The 3mm test rod is typically a cylindrical probe with a diameter
of 3mm. It is made of conducting material and is used to simulate a
solid object that may come into contact with live parts of an
electrical device. The purpose of this test is to ensure that the
device under test maintains appropriate clearance and creepage
distances, preventing electrical arcing or accidental contact with
hazardous voltages.
During the test, the 3mm test rod is systematically applied to
different parts of the device, including the terminals, openings,
or other accessible areas. The device's design and insulation
should prevent the test rod from making contact with live parts,
thus ensuring electrical safety.
It's important to note that the specific standards and procedures
associated with the 3mm test rod may vary depending on the context
and the applicable regulations. Therefore, it is recommended to
refer to the relevant standards, such as IEC 60884 or other
applicable electrical safety standards, for detailed guidelines and
specifications regarding the use of the 3mm test rod in electrical
testing.

Operation:
Please refer to the relevant standards.
Take IEC 60884:2013 clause 24.11 as an example:
A cylindrical steel rod, having a diameter of 3mm and a
hemispherical end with a radius of 1.5mm, is pushed perpenducular
to the supporting mounting surface, in the most unfavourable
position, for 10 s against the barrier, the force being equal to
1.5 times the maximum plug withdrawal force (as specified in 22.2,
table 16).
The test probe doesn’t have built-in force, if specific applied
force required, the test probe should work together with a force
gauge. At the end of our probe handle, there is a M6 thread hole to
match the force gauge. Showing as following reference picture:
