Information concerning the
CE
sign
Thermo Haake circulators and cryostats carry the CE sign
which confirms that they are compatible with the
EU
guideline
89/336/EEC (electromagnetic compatibility). The tests are
carried out according to module
H
(official sheet L380 of the
European Community) as our quality assurance system
is
certified according to DIN
1
IS0
9001.
The specialist basic standards to be applied are
EN
50081
-2
for interference emission and
EN
50082-2 for interference
resistance. The following tests were carried out:

There are thus no limitations placed on usage.

Our strict standards regarding minimum operating quality and
the resulting considerable amount of time and money spent
on development and testing reflect our commitment to guar-
antee the high level of quality of our products even under
extreme electromagnetic conditions. Practice however also
shows that even units which carry the
CE
sign such as moni-
tors or analytical instruments can be affected if their manufac-
turers accept an interference (e.g. the flimmering of a monitor)
as the minimum operating quality under electromagnetic
compatibility conditions. For this reason we recommend you
to observe a minimum distance of approx.
1
m from such units.
The CE-sign also certifies the conformity with the
EU-direc-
tive
72/23/EWG
(low voltage regulation). The applied stan-
dards are
EN61
01 0-1 and EN61 01 0-2-01 0.
