IEC 60320 C13/C14 (PC power cord) live, neutral, earth?

[mcovington]

Is there a standard that says which pins of an IEC 60320 C13/14 (PC power cord) are live and neutral?  Earth is obvious, but I haven't been able to find the spec for the other two.

Given the plug at the other end of the cord is not guaranteed to be polarized, I think the only sensible way to design a device with an IEC power input is to work with either polarity.

So I saw, in this thread:

My approach to safety might be provincially North American.  We have polarized outlets here.

I am also going to investigate the rumor that the polarization of IEC power cords varies randomly.

They are not randomly polarised. Some have single pole switches and/or fuses which should correspond to the live connection. Re-wireable connectors are usually labelled. Here's one that was to-hand:

Thanks.  That agrees with 3 cords that I just tested with a continuity tester (I added a red dot marking live):

Good  testing,  we had some china crap wires who where phases inverted, they dont care about  north america polarized  outlets
