14.3 Test Setup and Test Procedure
14.3.1 Test setup
Tabletop EUT
The EUT was put on a 0.8m high wooden tabel, standing on the ground reference
plane(GRP) 2.6m by 1.8m in size, made by aluminium 0.5mm thick.
A horizontal coupling plane(HCP) 1.6m by 0.8m in size was placed on the table, and
the EUT with its cables were isolated from the HCP by an insulating support thick
than 0.5mm. The VCP 0.5m by 0.5m in size & HCP were constructed from the same
material type & thinkmess as that of the GRP, and connected to the GRP via a 470k
plane(GRP) 2.6m by 1.8m in size, made by aluminium 0.5mm thick.
A horizontal coupling plane(HCP) 1.6m by 0.8m in size was placed on the table, and

material type & thinkmess as that of the GRP, and connected to the GRP via a 470k
Ω
resistor at each end.
The distance between EUT and any of the other metallic surface excepted the GRP, HCP
& VCP was greater than 1m.
The EUT was arranged and connected according to its functional requirements.
The distance between EUT and any of the other metallic surface excepted the GRP, HCP
& VCP was greater than 1m.
The EUT was arranged and connected according to its functional requirements.

Floor standing EUT
The EUT was put on a 0.1m high wooder support, standing on the ground reference
plane(GRP) 2.6m by 1.8m, made by aluminuim 0.5mm thick.

of the ground reference plane was applied ,and was connected to the GRP via a 470k
Ω resistor at
each end.
The distance between EUT and any of the other metallic surface excepted the GRP, HCP & VCP
was greater than 1m.
The distance between EUT and any of the other metallic surface excepted the GRP, HCP & VCP

The EUT was arranged and connected according to its functional requirements.
14.3.2 Test Procedure
The EUT was
d and connected according to its functional requirements
Direct static electricity discharges was applied only to those points and surface which are
accessible to
personnel during normal usage.
The test voltage was increased from the minimum to the selected test level and with single
The test voltage was increased from the minimum to the selected test level and with single
discharge.
On each preselected points 10 times of each polarity single discharge were applied
The time interval between successive single discharges is 1s.
The ESD generator was held perpendicula
The time interval between successive single discharges is 1s.
The ESD generator was held perpendicula
surface to which the discharge is applied. The
discharge return cable of the generator was kept at a distance of 0.2m whilst the discharge is being
applied. During the contact discharges, the tip of the discharge electrode was touch the EUT before
applied. During the contact discharges, the tip of the discharge electrode was touch the EUT before
air discharges, the round discharge tip of the discharge

removed from the EUT, the generator is then
triggered
for a new single discharge.
