T T echnical description according to EN 60601-1-2
Guidance and manufacturer's declaration – electromagnetic immunity
The Memmert steriliser type S.. is intended for use in the electromagnetic environment specified below.
The customer or user of the steriliser type S.. should assure that it is used in such an environment.
Immunity

Conducted RF 3 V
rms
IEC 61000-4-6 150 kHz bis 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz bis 2,5 GHz
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and poeple.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordlass) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broardcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic enviroment due to fixed RF
transmitters, an electromagnetic site survay should be considered. If the measured field strength in the
location in which the steriliser type S.. is used exceeds the applicable RF compliance level above, the
Steriliser type S.. should be observed to verify normal operation. If abnormal performance is observed,
addidional measures may be necessary, such as re-orienting or relocating the steriliser type S..
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Electromagnetic enviroment –
guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the steriliser type S.., including
cables, than the recommended seperation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d P
= 1,2
d P
= 1,2
80 MHz to 800 MHz
d P
= 2,3
800 MHz to 2,5 GHz
where P is the maximum power rating of
the transmitter in watts (W) according to
the transmitter manufacturer and
recommended separtion distance in
metres (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, a should be less than the
compliance level in each frequency range.
Interference may occur in the vicinity of
