10.2 Electromagnetic Immunity
The STERIclave B has been designed for use in an environment like the one cited
below. The customer or user of the STERIclave B should ensure that it is used in
the correct environment.
Immunity tests

(ESD) according to IEC
61000-4-2
± 6 kV contact discharge
± 8 kV atmospheric di‐
scharge
± 6 kV contact discharge
± 8 kV atmospheric di‐
scharge
Floors should be made of
wood or concrete or have
ceramic tiles. When the
floor is covered with syn‐
thetic material, the relative
humidity must be at least
30%.
Fast transient electrical
disturbances/ Bursts ac‐
cording to IEC 61000-4-4
± 2 kV for power lines
± 1 kV for input and output
lines
± 2 kV for power lines
± 1 kV for input and output

The quality of the supply
voltage should correspond
to that of a typical business
or hospital environment . If
the user of the STERIclave
B requires continued
operation even in the
event of the failure of the
power supply, we recom‐
mend that the STERIclave
B is connected to an unin‐
terruptible power supply
(UPS) or a battery .
Magnetic field with a sup‐
ply frequency (50/60 Hz)
according to IEC
61000-4-8
3 A/m
3 A/m
Magnetic fields at the
mains frequency should
correspond to typical valu‐
es in a business and
hospital environment .
Note: V
t
is the alternating mains voltage before the test level is used.
