Electrostatic discharge immunity test
Outline of the IEC61000-4-2 Ed 2.0
This standard stipulates the immunity requirements and test methods for electrical and
electronic equipment subjected to static electricity discharges, from operators directly,
and from personnel to adjacent objects. It additionally defines ranges of test levels
which relates to different environmental and installation conditions and establishes test
procedures. The range of the preferred test level for the ESD testing

• Put a 0.8 meter high test table (made of wood) on the ground reference
plane, then place the horizontal coupling plane on the test table.
• Connect two 470k resistors between the horizontal coupling plane and
the ground reference plane as shown in the fi gure.
• In the testing method of indirect discharge, it observes the effect of
EUT when discharging to the vertical or horizontal coupling plane.
● Test method
The contact discharge testing is preferred.
The air discharge testing should be applied only when the contact discharge testing can
not be performed.
• Put a 0.1 meter high of insulation pallet on
the ground reference plate, then place the
EUT on it.
• The Indirect discharge testing is the test
method to observe the effect to the EUT while
discharging to the vertical coupling plane.
• Connect two 470k resistors between the
vertical coupling plane and the ground
reference plane.
• Place the electrostatic discharge simulator
on the ground reference plane as close as
possible.
• Use a horizontal coupling plane (1.6m×0.8m) and a vertical coupling
plane (0.5m×0.5m)
• Connect two 470k resistors between the vertical coupling plane and
the ground reference plane.
• Distance between the horizontal coupling pane and the EUT
• Place the EUT about 0.1m from the edge of the horizontal coupling plane.
• Place the electrostatic discharge simulator on the ground reference
plane as close as possible.
