This is from the (potential) client's original email: "There is the unique 200 mA test method in EN 55103-2:2009, fig. B.3b) and B.4 which uses a "toroidal transformer" for injection beginning at 50 Hz."
He then states: "I do not like the method's uniqueness and the lack of an usual calibration procedure." And he goes on to say he wants a bulk cable injection technique similar to MIL-STD-461 CS114. That's where the the thread was punted my way. It's not too hard to inject 200 mA into a dead short, but as stated in the original post, there must be some way to bound the driving potential as well. A BCI technique at low audio frequencies is non-trivial if a potential of any magnitude must also be delivered.
