3.3 Information concerning the CE sign
Thermo Haake measuring and control instruments 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 / ISO 9001.
It was tested according to the strict EMV test requirements
of the EN61326-1/A1 (EMV requirements for electrical
equipment for measuring technology, conduction techno-
logy and laboratory usage). This means it was tested for in-
terference resistance and interference emission according
to public low-voltage mains (household and commercial
usage).
The following basic standards were applied in detail:
Interference resistance:
EN61000–4–2 electrostatic discharge
EN61000–4–3 electromagnetic fields
EN61000–4–4 fast transients
EN61000–4–5 surge voltages
EN61000–4–6 wire–guided HF–signals
EN61000–4–8 magnetic field of mains frequency
EN61000–4–11 voltage drop/short–time interruption
Interference emission:
CISPR16/class B wire–guided interference emission
CISPR16/class B radiated interference emission
EN 61000–3–2 Voltage variations and flickering
EN 61000–3–3 Over-compensation voltage flows
The application in industrial and commercial (public mains)
environments is thus possible.
A declaration of conformity is supplied with the ordered unit
on request.
Our strict standards regarding operating quality and the re-
sulting considerable amount of time and money spent on de-
velopment and testing reflect our commitment to guarantee
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 monitors or
analytical instruments can be affected if their manufacturers
accept an interference (e.g. the flimmering of a monitor) as
the minimum operating quality under electromagnetic com-
patibility conditions. For this reason we recommend you to
observe a minimum distance of approx. 1 m from such units.
