I do not have a copy of EN55024. But from IEC 61000-6-1:1997 " Electromagnetic compatibility (EMC)Part 6-1: Generic standards Immunity for residential, commercial and light-industrial environments", page 23 - Immunity DC input /output power ports- Note 4 Burst / Surge, I quote: "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 DC power input port intended for use with an AC/DC power adaptor shall be tested on the AC power input of the AC/DC power adaptor specified by the manufacturer or, where none is so specified, using a typical AD/DC adaptor. The test is applicable to DC power input ports intended to be connected permanently to cables longer than 10m".
So, the complete system shall be burst & surge tested according to IEC 61000-6-1:1997.
