Something else to remember is that if the product has lines over 30m long or (for some product standards) which pass outside buildings, then these must also be surge tested. Burst testing on I/O leads is required if they are over 3m long. These tests may apply to the system as a whole.

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.
