Where are you located?  Pick a lab that's close.
Meaning - so you can get in the car and drive
over there without too much trouble.

Europe requires three categories of testing for the
Information Technology Equipment category otherwise
known as "ITE": Emissions, Safety, Immunity.  The
estimated cost of the tests is based on the number
of shifts that have to be performed.  Be sure when
you visit the lab or labs you pick to note posted
certifications that should be in plain view some
where like in the main lobby and/or in the lab
where the tests are being done.

Emissions would be EN-55022A for non-residential
equipment.  Emissions testing is totally
non-destructive.  Emissions testing both
radiated and conducted (I know I'm probably
throwing terms at you) should take one shift
assuming of course the equipment isn't some
monstrous device.

Safety, if you're in the Information Technology
Equipment category (which state side is UL-1950),
then EN-60950 is applicable for the Low Voltage
Directive otherwise known as the LVD.  Safety
usually requires TWO power supplies for each
secondary output.  And those supplies may well
be destroyed.  Some tests require all night
testing and could take 4 to 5 shifts to complete.

Immunity, the US has no immunity so you'll have
to probably use EN-50082-1 series of tests.
There is a high probability with some of the
transient testing and ESD testing that the
equipment will be destroyed. Assuming no
problems, estimate about 3 to 4 shifts.

I would recommend the order of testing to be
Emissions, Immunity, then Safety.  If any
type of revision for chassis or frame or
power supply has to be done, this can have
a great impact on Safety.  So, it's a good
idea to put safety last.

There are labs that are "one stop shops" for
what I've mentioned above and lots more.

I've been doing compliance work in the ITE
area for almost 20 years now.
