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.
