Hi George, I haven't got a copy of EN55024, but if it is anything like the format of EN61000-6-2, then the info you are looking for will appear as 'notes' under immunity testing of dc input and output ports will read ...
"[EFTs & Surge] Not applicable to input ports intended for connection to a battery or a rechargeable battery which must be removed or disconnected from the apparatus for recharging. Apparatus with a d.c. power input port intended for use with an ac-dc power adaptor shall be tested on the a.c. power input of the ac-dc power adaptor specified by the manufacturer or, where none is specified, using a typical ac-dc power adaptor. The test is not applicable to d.c. power input ports intended to be permanently connected to cables less than 10m in length " This excerpt from BS EN 61000-6-2:1999 Table 3, Note 3. Not sure if EN55024 has similar statement.

They suggest that the AC/DC power supply, but not the ITE, has to pass Surge, etc. I'm sure that the whole system has to pass, but I don't know chapter and verse to quote. I suppose the scope should be spelled out in EN55024 but I don't have a copy of it, yet. Thanks in advance.
