Thanks, that's certainly a useful document. However, I'm confused. It appears to be an IEEE (ie American) standard, but it does make reference to the IEC. The international standard, as far as I can tell, is IEC60617. I don't know if there is an ISO standard or if IEC60617 was produced in conjunction in some way with the ISO. Does this document in fact represent IEC60617?
There has been quite a bit of discussion about libraries on the list recently. IMHO it would be better if kicad libraries as a minimum followed an international standard; I know I'm not the only person not to recognise library symbol CAPAPOL, and that's just a capacitor. Should that standard be IEC60617 or something else? I did try to find a copy of IEC60617, but the IEC want money for it. Regards, Robert.
