ESD Testing requirements per IEC 61000-4-2

Version : 21.03.03 , based on 61000-4-2:1995 /A2:2000

EMC-Partner Generator : TRA2000

1. General

Testing take place in climatic specification as follows:
Ambient temperature :               15°C to 35°C
Relative Humidity :                     30% to 60%
Atmospheric Pressure :              86kPa (860 mbar) to 106kPa (1060 mbar)
Other values may be specified in the test specification.

• A ground reference plane (GRP) is required.
• The EUT shall be positioned at least 1 meter from walls and metallic structures.

• Positioning of power and signal cables shall be representative of good installation practice.
• The EUT shall be conected to a grounding system, representative of good installation practice; no additional earthing connecions are allowed
• The discharge return cable should, where possible, be placed off the ground reference plane, and should not come closer than 0.2 meters to other conductive parts of the test setup.
• Vertical Coupling Planes (VCP) and Horizontal Coupling Planes (HCP) max be used for indirect application of the ESD pulse. These planes shall be constructed from the same material and thickness as the ground plane, and should be connected to the ground plane by a cable with two 470kohm resistors, one resistor at each end of the cable
• For tabletop equipment, a non-conductive table 0.8 meters high is placed on the ground plane. A ground plane (HCP) 1.6 meters by 0.8 meters will be put on the table, and the EUT and any cables shall be placed on an insulating support 0.5mm thick placed on top of the HCP. The HCP shall be connect to the ground reference plane with a resistive cable as in previous paragraph.
