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

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).
