schematic, pneumatic abbreviations
iec standard electrical/pneumatic circuit diagrams. i need abbreviaton/reference designators for pneumatic symbols, specially for tube fittings....  
i think one on the links in this thread might help.
so far what i know: pneumatic reference designators for actuators -a; silencer -z; valves -v, and how you can see not to much. i am working on a schematic and i need an iec "must to be" , abbreviation for tube fittings!
will iso symbols not work, or am i misunderstanding.  this is one of the links i mentioned.
