I'm studying electronics in college (I live in Europe), and they are teaching us we should form our reference designations of elements when designing a circuit as according to EN 81346.
This seems absurd to me, because it might be OK for a meat grinder and a generator to have the same designations (G) in some sort of a big automation system, but in a small electronics circuit to name both a diode and a resistor with R, just because they do something to current.. i can't accept that. After looking it up on wikipedia, it seems to me that the classical designations R for resistor, D for a diode, etc. are from the American (ANSI) standard.
I know this sort of thing is entirely voluntary, but I just want to know: Does that standard (EN 81346) really apply to every type of electrical circuit? Are there any other European norms or ISO standards relating to reference designation?
