Ok, good point - add SAE J1113 to the list. For some of the stuff my employer makes, our internal rule is 40V at 40A for the 8/20 waveform for 12V systems. I have seen much worse on military 24V machines.
Surge immunity is a really really big thing for stuff that is attached to the bus that is directly connected to the battery/alternator node. Not so much if using aux power connectors on vehicles made in recent years. There are several companies that make special surge arrestor components just for ground vehicles.
