7.4
Standardised European norms
It is asssumed that devices which comply with the conventional standar
dised European norms (EN ....) also meet the protection requirements.
If the manufacturer of a device has applied the European norms only in
part or not at all, or if there are no applicable norms for the device in ques
tion, the protection requirements are considered satisified if this is con
firmed by certification from a competent body.
7.4.1 Application
EMC norms are arranged hierarchically as basic norms, generic norms,
product family norms and product norms.
EMC basic norms
EMC basic norms describe measuring methods for individual electromag
netic phenomena. They offer suggested test values, but do not generally
include limit values.
EMC generic norms
EMC generic norms describe electromagnetic ambient conditions. They
provide limit values for individual electromagnetic phenomena according
to the measuring methods in the EMC basic norms.
d
EMC generic norms are
to be applied in part
where fundamental
electromagnetic phenomena are not covered by EMC product norms
or EMC product family norms.
d
EMC generic norms
should not be applied
where EMC product
norms or EMC product family norms are available.
EMC product family norms
EMC product family norms provide limit values for individual electromag
netic phenomena according to the ambient conditions of the EMC generic
norms and according to the measuring methods of the EMC basic norms
for a product family.
EMC product family norms have precedence over EMC generic norms.
EMC product norms
EMC product norms provide limit values for individual electromagnetic
phenomena according to the ambient conditions of the EMC generic
norms and according to the measuring methods of the EMC basic norms
for a product.
EMC product norms have precedence over EMC product family norms
and EMC generic norms.
