There is a list of partners from cenelec on their web site.
Most are european. One adress is 400 meters from my
ttest house away. If you want to i can help you
in selecting and ordering.
They have a web site too: www.nni.nl

If i do understand your question:
That is why you need a technical file, several of the radio test cannot be
applied to a modem, so it is exempted for technical reasons. It will need to
operate while testing your system, and also during radio EMC tests. Your risk
analysis will show what are
Hi David,
CISPR 32 is not relevant as this is not a Harmonised European standard.
While CISPR IEC and EN standards may have similar numberings, they are
not the same in all aspects.
EN 55032 _is_ a Harmonised European Standard (based on CISPR32) and
applies to both Industrial and
it to a new product.

The LVD does NOT apply.
For elektrical safety and EMC the RED will use it's proper list of
harmonised standards.
As says:
Art 1.4
/Radio equipment//falling within//the scope of this Directive//shall
_*not*_ be subject//to Directive//2014/35/EU,//except as//set out in
point (a) of Article
As LVD (2014/35) is not applicable for Radio devices and so RFID, this
standard is set up to be harmonized
under the RED. Be it as an Electrical Safety Standard under the RED.
Look at the provided link.

EMC testing is like speeding by car. Did you ever try convince an
officer that you drove too fast for only a few minutes by year if caught
over-speeding? And what did he say ?
Ports do not need testing only if inoperable at all. And even than, from
a technical point of view it may generate
Life is consist of risk assessments!
If you cross a road, you quickly assess the risk of safely getting to
the other side.
What you call a scientific method, is a risk assessment based on
physical hypotheses , but the hypothesis might be wrong tomorrow, or in
another place. But the chance
I believe that charging a device within the MDD when connected to a
patient is not normal use but to be classified (foreseeable) misuse.
Some remarks:
1. An apparatus that requires charging is most often meant to be used
while not connected to the mains; why use a battery otherwise. Most
The EMC tests as called out in 60335 are safety tests, contrary to
those called out under the EMCD that are functional tests only. For
Europe , one can discuss about the necessity of those tests, as the
EMCD requires testing in all operating modes including OFF or standby
and as long as one
IMHO all probes are calibrated under far field conditions.
In general: Using probes in the proximity (< lambda) of anything
conductive (including ground planes at 10 cm and including EUT) makes
the measurement data useless.
As James correctly states, the construction of the probe makes this
to the requirement.
The fact that a radiated instead of a conducted measurement is made ; is
more close to
the essential requirement.
For test phenomena both are equal (but for the F-range)
Then the choice for immunity should follow the same logic.

Hi Chet,
There are many other standard electronic equipment that qualify them
for these tests; possibly not in the phase of compliance seeking, but
at least when looking for simple quality.
Magnetic fields tend to build up low value EMF sources in series with loops
and have extremely low
As i remember the factor L (cable length) in the equation
is an simplification of the real value sin(L). As one may
remember , sin(L)=L for L very small. As the formula
was meant for small dipoles, that is close to correct.
I remember also that already L in sinus(L) was simplified
from a factor
