Hi Amund,
The Europe the GSM frequencies for Europe are 900 MHz and 1800MHz bands.
The test requirement you are looking for has been incorporated into
CISPR35 drafts will eventually be adopted into EN55035. The
CISPR35/FDIS includes a requirement for spot testing both 900 MHz and
1800 MHz. CISPR35 did not get approved in the most recent vote, but the
issues raised did not impact these spot frequencies. Instead, there are
some debates about the levels required for radiated immunity at these
spot frequencies for equipment marketed for use in telecommunications
centers or central offices (30 V/m). As long as the PC monitor does not
have a network function that is intended for use in this environment,
then the manufacturer can decide what protection distance the product
must be immune to radiated immunity frequencies with 3 V/m for 3 meter
protection distance being the easiest level to achieve. The harsh 30
V/m level is for the protection distance of 20 centimeters. Personally,
I encourage use of the half meter protection distance which requires
being immune to 12 V/m. All of this will be made clear when the
CISPR35 is finally passes and the standard is published. If desired,
you can get a look at the proposed radiated immunity requirements by
looking at Europe's non-harmonized standard EN50635 today.
CISPR and CISPR/I is meeting in Frankfurt during the week of October
20th, and they will figure out a path forward to get CISPR35 approved
quickly (I'm guessing 6 months). Europe will likely publish EN55035
about 3-6 months after that. The bottom line is that the immunity test
requirements you are looking for are coming soon....

Concerning CE marking of PC monitors ... shall they be immune to GSM mobile
phones?
I can't find any GSM mobile phones test requirements under EU harmonised
standards. I recall there was a standard (ENV50204) a long time ago, under the
Generic standards. That one is not with us anymore.
Have I missed a point?
