MIL Standards: MIL-STD-461G CS118: Personnel Borne Electrostatic Discharge (ESD)

The New MIL-STD-461G, CS118, has added the Electrostatic Discharge testing section of conducted susceptibility, referred to as CS118. The ESD levels, test setup and test equipment are similar to IEC 61000-4-2 and RTCA/DO-160. In order to see the full version released on 12/11/15, View MIL-STD-461G.

CS118 Applicability

This requirement is applicable to electrical, electronic, and electromechanical subsystems and equipment that have a man-machine interface. It is not applicable to equipment that interfaces with or controls ordnance items.

CS118 Limits

The EUT shall not exhibit any malfunction, degradation of performance, or deviation from specified indications, beyond the tolerances indicated in the individual equipment or subsystem specification, when subjected to the values shown Table CS118-1. Contact up to 8kV is the required method. Air discharges shall be required only if specified by the procuring activity.


This test procedure is used to verify the ability of the EUT to withstand personnel borne electrostatic discharge (ESD) in a powered up configuration:
  • ESD Simulator Gun
  • LISN or other Isolation Transformer
  • GP: Ground Reference Plane (Aluminum or Sheet Metal)
  • HCP: Horizontal Plane (Aluminum or Sheet Metal)
  • VCP: Vertical Coupling Plane (Aluminum or Sheet Metal)
  • 470 kOhm Resistor Cables to mount from HCP/VCP to GP
  • Insulation Material (Polyvinyl Chloride preferred material)
