The second model is IEC 1000-4-2 and is used to

simulate the reaction of the device on equipment

when subjected to electrostatic discharges, which

may occur from personnel to objects near vital

instrumentation. Direct (Contact) and indirect (Air

Gap) applications of discharges to the equipment

under test (EUT) are possible. Test characteristics

are shown in circuit, waveform and table below.
