With batteries, it is much more likely done by the makers, than by
UL. They test electronic products that contain AC fed (generally)
electronic assemblies. DC to DC converters find CSA and other ratings
and certs, but UL doesn't usually do single components (as these
sometimes are considered as) so much as systems or assemblies to be
used as a part of a system.
Our large DC fed Anode supply was one of their first. One of our
engineers had to go down there, with several supplies for days and
train the UL personnel in how to test an HV supply, and an isolated,
DC fed one, at that. A first for them as I recall them saying. We had
wires coming up out of the potting on two of the supplies.
But you are right... Push 'em till they blow.
