Check out the Construction Product Directive 89/106 to see if it may apply.
There is a "safety in use" essential requirement.
I don't know for sure, but I have heard that no standards have been
published for this directive.

Subject: Dome Structure - Machinery Directive?
My company designs and manufactures visual systems for use in
simulation and
training. Aside from the computers, projectors and other electronic
devices
used with these systems (which are CE marked), we also deliver these
"visual
systems" with some type of visual environment such as a dome. This
dome
serves as the screen surface as well as providing the structure for
installation and maintenance of this equipment. I have a customer
that has
requested a CE mark for the entire visual system including the dome
structure. My first inclination was to look at the machinery
directive, but
from my perspective, a dome does not seem to fit any of these
categories.
"an assembly of linked parts or components, at least one of
which
moves, with the appropriate actuators, control and power
circuits,
etc. joined together for a specific application, in particular for
processing, treatment, moving, or packaging of a material."
or
"an assembly of machines, which in order to achieve the same
end,
are arranged and controlled so that they function as an
integral
whole."
or
"interchangeable equipment modifying the function of a
machine,
which is placed on the market for the purpose of being assembled
with a
machine or series of machines or with a tractor by the operator
himself
insofar as this equipment is not a spare part or a tool."
Given that there are safety concerns with a dome structure such as
flammability (fiberglass dome structure), ladders/platform hazards
(falls,
servicing etc), emergency egress, lighting and overall structural
integrity,
CE marking seems reasonable. The question is to what standard(s)?
I would prefer to avoid the time and expense of turning this over to
a
"Notified Body" for a dome evaluation, and would hope that there are
standards which would fit the various elements of this design. Any
suggestions would be greatly appreciated.
