Measurement of immunity to eletrostatic discharge (EN 55020 - Sec. 5.9)
8.0
Method:
In the case of air discharges, the round discharge tip of the discharge electrode shall be approached as fast as possible (without causing mechanical
damage) to touch the EUT. After each discharge, the ESD generator (discharge electrode) shall be removed from the EUT. The generator is then
retriggered for a new single discharge. This procedure shall be repeated until the discharges are completed. In the case of an air discharge test, the
discharge switch, which is used for contact discharge, shall be closed.

retriggered for a new single discharge. This procedure shall be repeated until the discharges are completed. In the case of an air discharge test, the
discharge switch, which is used for contact discharge, shall be closed.
Indirect application of the discharge:
Discharges to objects placed or installed near the EUT shall be simulated by applying the discharges of the ESD generator to a coupling plane, in the
contact discharge mode.
Discharges to objects placed or installed near the EUT shall be simulated by applying the discharges of the ESD generator to a coupling plane, in the
contact discharge mode.
Horizontal coupling plane (HCP) under the EUT:
Discharge to the HCP shall be made horizontally to the edge of the HCP. At least 10 single discharges (in the most sensitive polarity) shall be applied at the
front edge of each HCP opposite the centre point of each unit (if applicable) of the EUT and 0.1 m from the front of the EUT. The long axis of the discharge
electrode shall be in the plane of the HCP and perpendicular to its front edge during the discharge. The discharge electrode shall be in contact with the
edge of the HCP. In addition, consideration should be given to exposing all sides of the EUT to this test.

edge of the HCP. In addition, consideration should be given to exposing all sides of the EUT to this test.
Vertical coupling plane:
At least 10 single discharges (in the most sensitive polarity) shall be applied to the centre of one vertical edge of the coupling plane. The coupling plane, of
dimensions 0.5 m x 0.5 m, is placed parallel to, and positioned at a distance of 0.1 m from, the EUT. Discharges shall be applied to the coupling plane, with
sufficient different positions such that the four faces of the EUT are completely illuminated.
