IEC 1000-4-4 (IEC 801-4):
Burst transients
Simulation of interference brought about by coupling
with a contactor, relays or similiar devices.
IEC 1000-4-5 (IEC 801-5):
Surge transients
Simulation of transients brought about e.g. by light-
ning that strikes near installations.
ENV 50141 (IEC 801-6):
Cable conducted HF
Simulation of the effect of radio transmission
equipment coupled to connection cables.
VDE 0160 class W2 testpulse
(draft Oct./1990 yellow):
Mains transients
Simulation of high-energy transients brought about by
main fuse breakage, coupling with phase
compensation batteries etc.
Immunity
In order to document immunity towards interference
from electrical phenomena that are coupled in, the
following immunity test has been made on a system
consisting of a VLT
frequency converter (with RFI fil-
ter module),

Fault criteria and test were in accordance with
EN 50082-2 and IEC 22G/31/FDIS.
The tests were made using the following standards:
IEC 1000-4-2 (IEC 801-2/1991):
Electrostatic discharges (ESD)
Simulation of electrostatic discharges from human
beings.
IEC 1000-4-3 (IEC 801-3):
Incoming electromagenetic field radiation
Simulation of the effects of radar and radio
communication equipment as well as mobile
communication equipment.
SEN 361503
Mains disturbance
Simulation of conducted capacitive interference
between control cables and adjacent mains cable.
