18.2.1.2 Electromagnetic Immunity
Interference Im-
munity Tests
IEC 60601
Test Level
Compliance Level
Electromagnetic
Environment - Guidelines
Electrostatic dis-
charge (ESD)
according to IEC
6100042
+/- 6 kV
contact discharge
+/- 20 kV
contact discharge
Floors should be made of
wood and concrete or be tiled
with ceramic tiles. If the floor
is covered with synthetic floor-
ing material, the relative air
humidity must be at least
30%. Can be used when
higher ESD levels are pre-
sent.
+/- 8 kV
air discharge
+/- 20 kV
air discharge
Short, transient
electrical disturb-
ances / bursts
according to
IEC 61000-4-4
+/- 2 kV for
network cables
+/- 2 kV for
network cables
The quality of the supply volt-
age should be equivalent to
that of a typical business or
hospital environment.
+/ 1 kV for
input and output
cables
Not applicable
Surges according
to
IEC 61000-4-5
+/- 1 kV transversal
voltage
+/- 1 kV transversal
voltage
The quality of the supply volt-
age should be equivalent to
that of a typical business or
hospital environment.
+/- 2 kV longitudinal
voltage
+/- 2 kV longitudinal
voltage
Voltage dips,
short interruptions
and fluctuations in
the supply voltage
according to IEC
610004-1-1
<5% U
T
(>95% dip in U
T
) for
half a period
<5% U
T
(>95% dip in U
T
) for
half a period
The quality of the supply volt-
age should be equivalent to
that of a typical business or
hospital environment.
If the person using the bed
requires that the bed functions
must continue despite any
interruptions in the energy
supply, it is recommended
that the bed be connected to
an uninterruptible electricity
supply or a battery.
40% U

Magnetic fields
with a supply
frequency
(50/60Hz) accord-
ing to IEC
6100048
3 A/m
3 A/m
Magnetic fields with a network
frequency should be equiva-
lent to those to be found in a
typical business or hospital
environment.
Note: UT is the AC network voltage before the test level is applied
