Reference Designators Anyone?

Reference Designators Anyone?

Reference Designators Anyone?

(OP)
Folks-
It used to be that IEEE 200/ANSI Y32.16 was the governing standard on electrical and electronic reference designators (e.g. 'R' nos for resistors, 'C' nos for capacitors, 'L' nos for inductors, E nos for terminals and antennae, etc.).  ASME Y14.100-2000 invokes IEEE 200 and IEEE 315.  Last week though I got a quote to buy these and learned that IEEE 200 has been cancelled with no replacement.  Does that mean that only IEEE 315 is now in place?

I think it is an acceptable practice (and sometimes a preferred practice) to call out reference designations in lieu of find nos on an assembly drawing.  Our company has a configuration manager who has never seen them anywhere but on circuit board drawings so she doubts they can be used elsewhere!

Granted this is done all the time on PWA/CCA drawings but is there some exclusion that limits their use only to there?

I've found it can make for a very clean drawings when you call components out by their reference designators!  Of course the reference designators are included on the bill of material to show what their part nos are.

I'm caught in a company with no drafting experience on production DoD programs and with a CM group staffed (and managed) by people with no experience with "Level 3" documentation!  I "lead them to water" regularly but can't get them to drink!
