IEC 1000-4-5 is written with DC supplies in mind. In fact, generic and product standards in the EU require testing DC supply lines using IEC 1000-4-4 and 1000-4-5. Most surge simulators designed for surging AC lines can also be used for surging DC lines (some require an option to work on DC lines; some don't).
In any case, the requirement is the same: a coupler -- usually via a an 8 to 10uF capacitor; a backfilter to allow voltage to be developed to the product being tested; and some kind of protection for the ac or dc source. This is generally built-in to modern surge generators for things like 48VDC lines up to 20-30A. Let me know if you want more information.
