Yes, there are big rooms that will accommodate large vehicles or some
large but movable objects, but not everything is movable. As I said, it
would be a very special case, but it it strictly an answer to the
question. I certainly agree that there are other possibilities.

In-situ testing to this standard makes no sense. It was not written
for in-situ, and compliance to this standard in-situ has no meaning.
Better build a Technical File, using the limits and basic tests from
that standards, or make your
own combination of tests and levels. The generic standards EN
61000-6-1/2/3/4 can be very helpful here to comply with.
Then search for a notified body to back-up your choices, and/or modify
those.
The ask the authorities for permission to carry out immunity tests
(61000-4-3 and en 61000-4-6)
outside a test area. That permission will not be granted easily, as
there are very large test rooms
available world wide, large enough to host a truck, or helicopter. So
you can go there, and
get back to the test methods of EN 55035/32........

Of course, but any in-situ immunity test would be a very special (and
probably very costly) case, for which a dispensation for specific
frequencies and/or times of use might be granted.

All,
There is one serious problem with in-situ testing to EN 55035. What
regulator is going to allow you to perform radiated immunity testing
from 80 MHz to 1 GHz at 3 V/m out in the open? And at certain spot
frequencies above that to as much as 30 V/m? I suspect that this
would be a roadblock to any such proposed testing.

If you could set up a reasonable test scheme, you could use EN 55035
for in-situ.
Listings in the OJ are held up for legal reasons; the situation is
quite complex but has recently been discussed in this forum.

Hello
EN 55032/CISPR 32 state in their scope that “ In-situ testing is
outside the scope of this publication.”
EN 55035/CISPR 35 make no mention of in-situ.
Any thoughts on EN 55035/CISPR 35 being applicable to in-situ
testing?
Also, EN 55035 appears in the RED list of harmonized standards.
Any thoughts about applying it to MME for the EMCD since no EMCD
list of harmonized standards has been published since August 2018.
All opinions will be welcome.
