IEC1000-4-4 (previously 801-4) covers electrical fast-transient/
burst (EFT) immunity. Electrical fast transients occur as a
result of arcing contacts in switches and relays. The tests simu-
late the interference generated when for example a power relay
disconnects an inductive load. A spark is generated due to the
well known back EMF effect. In fact the spark consists of a
burst of sparks as the relay contacts separate. The voltage appear-
ing on the line, therefore, consists of a bust of extremely fast tran-
sient impulses. A similar effect occurs when switching on
fluorescent lights.
The fast transient burst test defined in IEC1000-4-4 simulates
this arcing and its waveform is illustrated in Figure 28. It con-
sists of a burst of 2.5 kHz to 5 kHz transients repeating at
300 ms intervals. It is specified for both power and data lines.

The ADM2xxE family of products are tested using both the
above mentioned test methods. All pins are tested with respect
to all other pins as per the MIL-STD-883B specification. In
addition all I-O pins are tested as per the IEC test specification.
The products were tested under the following conditions:
(a) Power-On—Normal Operation
(b) Power-On—Shutdown Mode
(c) Power-Off
There are four levels of compliance defined by IEC1000-4-2.
The ADM2xxE family of products meet the most stringent
compliance level for both contact and for air-gap discharge. This
means that the products are able to withstand contact discharges in
excess of 8 kV and air-gap discharges in excess of 15 kV.
