Has anyone received concrete direction for engineering development apparatuses that they would be willing to share and/or point to? 

I can't give you an official reference, but my understanding is that these design aids, being confined to technical areas where people are assumed to know about EMC, are not subject to the CE marking requirements but ARE required not to interfere with other equipment unreasonably.

(side note - I expected apparati, but apparently that's not the plural form)
 
'Apparatus' is the past participle of 'apparare', Latin for 'to prepare', and thus means 'prepared' (although as a stand-alone adjective in Latin it meant 'ready' or 'well-supplied'). So the plural would indeed be 'apparati', but in English, 'apparatus' WAS, before the Europeans got at it, a collective noun and the plural was 'apparatus'. The Continentals don't like English collective nouns, so we have to put up with 'apparatuses' and 'equipments'.

I'm still looking for an instance of 'datae' or even 'dataes' (a p-p-p-plural. (;-)
