For the standards route to compliance only standards listed in the OJ with
reference to the EMC directive can be used. EN50130-4 is listed, EN54-2
is not. With regards to the EMC directive, EN50130-4 wins.
You will still need to do what your customers want you to do and that may
include EN54-2, but there is no need to do it under the EMC directive.
I'd advise that you attempt to get them to accept EN50130-4 in leu of the
immunity tests you describe.
