9. Electrostatic Discharges
9.1 Test Procedure
A ground reference plane was located on the floor, and connected to earth via a low impedance connection.
The return cable of the ESD generator was connected to the reference plane. In case of a floor standing
equipment, EUT was placed on the reference plane on 0.1 m of insulating support.
In case of table-top equipment, EUT was placed on a wooden table 0.8 m above the reference plane.
A horizontal coupling plane (HCP) of 1.6 m x 0.8 m was placed on the table, and connected to the reference
plane via a cable with a 470 ㏀ resistor located in each end (0.5 mm insulating support between EUT and
HCP). In both cases a vertical coupling plane (VCP) of 0.5 m x 0.5 m was located 0.1 m from each sides of the
EUT. The VCP was connected to the reference plane in the same matter as the HCP.
The test was done by applying contact and air discharges to the EUT itself, and contact discharges to the HCP
and VCP. When applying the discharges to the HCP, the tip of the generator was located at the front edge of
each HCP opposite the center point of the EUT, at 0.1m distance. When applying the discharges to the VCP the
tip of the generator was located at the middle edge of the VCP. The VCP was located 0.1 m from each side of
the EUT. Contact discharges up to ±2 kV, ±4 kV were applied to various points of the EUT at conductive
surfaces, and to the HCP/VCP. Air discharges up to ±2 kV, ±4 kV, ±8 kV were applied to various points of
the EUT at non-conductive surfaces.
Ungrounded equipment, or ungrounded part(s) of equipment, cannot discharge itself similarly to class I mains-
supplied equipment. If the charge is not removed before the next ESD pulse is applied, it is possible that the
EUT or part(s) of the EUT be stressed up to twice the intended test voltage. Therefore, double-insulated
equipment could be charged at an unrealistically high charge, by accumulating several ESD discharges on the
capacitance of the class II insulation, and then discharge at the breakdown voltage of the insulation with a
much higher energy. In the case of class II & III equipment, to avoid of unrealistically high charge, it is
possible to ionize “using ionizer” before each discharge.

10. Radiated Electromagnetic Field
10.1 Test Procedure
The tests were performed at 3 m distance in an anechoic chamber.
For floor-standing equipment, the EUT was mounted a non-conducting support 0.1 m above the
supporting plane. For tabletop equipment, the EUT was located on a wooden table 0.8 m above the floor.
The EUT was exposed to the field from different angles, normally 0º, 90º, 180º, 270º and at both
supporting plane. For tabletop equipment, the EUT was located on a wooden table 0.8 m above the floor.
The EUT was exposed to the field from different angles, normally 0º, 90º, 180º, 270º and at both
horizontal and vertical polarization (antenna height 1.75 m)
A signal level of 3 V / m, 80 % AM modulated with a 1 kHz sine wave was applied in the frequency
range 80 – 1000 MHz.
