CONSIDERATION OF EMC ENVIRONMENT
When considering the relevant EMC emission and immunity standards it is important to distinguish between the following classes of EMC environments:
Residential, supplied
directly from public
electricity supply
Commercial and
light industry,
supplied directly
from public
electricity supply
Industrial
installation with a
separate
transformer station
RF emission
Immunity
RF emission
Immunity

EN 61800-3)

EMC measures do not
have to be implemented
If interference in a
neighbouring
installation occurs, the
operator is responsible
for taking measures to
prevent interference. In
this case the required
emission levels must be
adhered to at the point
of supply to the effected
neighbouring
installation.

This new Product Standard Draft has not yet been
finally passed and more important, is not EC approved.
An EC Declaration of Conformity for EMC can only be
issued with the approval of a "Competent Body". It is
anticipated this standard will be officially released
during Q 3/4 1996.
* New standards to be introduced in the near future
Standards for immunity:
IEC801-2 (IEC1000-4-2*):
Electrostatic discharge (e.g. from electrostatically charged persons)
IEC801-3 (IEC1000-4-3/6*):
Electromagnetic fields (e.g. from portable telephones)
IEC801-4 (IEC1000-4-4*):
Fast electrical transients (burst) (e.g. from opening contacts in inductive circuits)
IEC801-5 (IEC1000-4-5):
Voltage surges (e.g. on local lightning strikes).
