My company designs and manufactures ATE systems and components for the
Military, Aerospace and Functional test markets. Often what we are supplying
is just an interface adapter (IA) that sits between another suppliers ATE
and the customers unit under test (UUT). 

An IA consists of a metal box mounted on the front of the ATE, with I/O
connectors on most panels. Whilst it is normally the case that the IA
consists entirely of passive components, they do route AC power through to
the UUT. From an EMC point of view, as they are passive and a component of a
larger system (the ATE), the EMC directive need not apply.

The problem is the LVD. Whilst we design and manufacture the item to meet
the relevant harmonised standard (EN61010), the safety of the IA is often
heavily dependant on the parent ATE (for which we are not the design
authority), due to the use of safety features in the ATE (i.e. interlocks
etc.)

Historically, we have not CE marked these IAs. Are we correct?

Dave Coleman
