2.1 TEST SETUP 
 
The EUT setup was placed in the ESD test laboratory in accordance with the IEC 
standard, with the following climatic conditions: 
 
  Temperature: 24.1 

degrees 

C 

 

 
 

 

Relative Humidity:   31 % 

 
The EUT was connected as diagrammed in Section 1.3 of this report.  
 
A horizontal coupling plane (HCP) was placed on a non-conductive table, 0,8 meters 
above the ground plane and connected to the ground plane through two 470-kohm 
resistors. The EUT was placed on the table with an insulating support between the EUT 
and the HCP. The ESD simulator was charged and allowed to discharge through the 
HCP See section 9 for photographs of typical setups. 
 
A vertical coupling plane (VCP) measuring 0,5m by 0,5m was fixed 0,1m from the 
vertical surfaces of the equipment, parallel to them and connected to the ground plane 
through two series 470 kohm resistors.  The ESD simulator was charged and allowed to 
discharge to the VCP.  This test was repeated until all vertical surface areas of the EUT 
were exposed to the VCP. 
 
The ESD events were applied to such points and surfaces of the EUT that are normally 
accessible to the operator for normal operation or maintenance.  Contact discharge is 
the preferred test method.  Air discharges are used where contact discharge cannot be 
applied.
