5.3 ELECTROSTATIC DISCHARGE (ESD)
5.3.1 TEST SPECIFICATION
Basic Standard
EN 61000-4-2:
2009
Discharge Impedance
330 ohm / 150 pF
Discharge Voltage
Air Discharge : 8 kV;
Contact Discharge: 4 kV
Polarity
Positive & Negative
Number of Discharge
Minimum 10 times at each test point
Discharge Mode

1 second minimum
5.3.2 TEST PROCEDURE
a) The EUT was located 0.1 m minimum from all side of the HCP (dimensions 1.6m * 0.8m).
b) The support units were located another table 30 cm away from the EUT, but direct support unit
was/were located at same location as EUT on the HCP and keep at a distance of 10 cm with EUT.
c) The time interval between two successive single discharges was at least 1 second.
d) Contact discharges were applied to the non-insulating coating, with the pointed tip of the generator
penetrating the coating and contacting the conducting substrate.
e) Air discharges were applied with the round discharge tip of the discharge electrode approaching the
EUT as fast as possible (without causing mechanical damage) to touch the EUT. After each
discharge, the ESD generator was removed from the EUT and re-triggered for a new single
discharge. The test was repeated until all discharges were complete.
f) At least ten single discharges (in the most sensitive polarity) were applied at the front edge of each
HCP opposite the center point of each unit of the EUT and 0.1 meters from the front of the
EUT. The long axis of the discharge electrode was in the plane of the HCP and perpendicular to its
front edge during the discharge.

g) At least ten single discharges (in the most sensitive polarity) were applied to the center of one
vertical edge of the Vertical Coupling Plane (VCP) in sufficiently different positions that the four
faces of the EUT were completely illuminated. The VCP (dimensions 0.5m * 0.5m) was placed
vertically to and 0.1 meters from the EUT.
