230v AC rating is 24 amps. However, this doesn't mean the
cable will melt at 25 amps. It's simply a guide that
mains voltage drop will be acceptable at that current
over the lengths likely in a domestic environment.

I'm under the impression that heating inside conduits with
multiple conductors and long-term degradation of insulation
is considered when rating electrical wiring.

Correct. The current rating is tied to a specified temperature rise of
a specified length in a specified conduit (can't remeber the details,
but it's all in an ISO spec somewhere).
