I've been looking at a lot of schematics over the last week and it looks like there is no agreed set of symbols that would constitute a standard. Or, some companies just choose to do things their way. So I was wondering if there is a stet of standards for symbols (and other aspects of electronic drafting) and how I can get a copy?
Except that EDIF could have been great if the committee had been competent. As it is, there are so many variations, that all follow the standard, that the interoperability they envisioned is all but impossible.
Are we talking about the same thing? IEEE 315 (-1975, and the 315A-1986 supplement) is the one with all the basic symbols; resistors (rectangle and zigzag are both allowed), capacitors, inductors, BJTs, FETs, vacuum tubes, etc.
In my experience most drawings follow this, but many get the details wrong for less common components such as thermal fuses, transducers, ganged switches, etc. It is handy to be able to look up the correct symbol for things one does not use often.
IEEE 315 also has a list of preferred reference designators, which is a handy thing to standardise on to maintain consistency between BOMs, purchasing systems and CAD systems.
On the other hand "IEEE Graphic Symbols for Logic Functions" is more controversial, and less widely used.
