IEC555-5
I think it is referenced by several specs for various telecoms gear (2Kv ac
for 1m followed by megger at 500vdc should be greater than 100M or 20M if a
number of circuits are tested. This standard is applied to all DC gear
attached to the rail network and the spec is indexed by EN50121-4 and -5
this is the standard applied to all battery charging systems that we make.

Subject: [EE] hipot tests for 48VDC bus

Does anyone happen to have the specs on what voltage you test for when doing
a DC hipot test on a 48VDC distribution system?
   
  We could just ask our bus bar vendor to provide a document saying it
passes, but would like to know what the standard specs are to test against.
   
  thanks in advance
