LARRY,
        THE A IN IPC-A-610 STANDS FOR ASSEMBLY AND THE B IS THE REVISION 
     LETTER OF THE DOCUMENT.  SO WHAT YOU HAVE IS SOME ONE CALLING OUT AN 
     IPC ELECTRONIC ASSEMBLY ACCEPTABILITY GUILDLINE, REVISION B.  THIS IS 
     A LEGIT CALL OUT ON AN ASSEMBLY DRAWING OR DESIGN SPEC.  WE REFERENCE 
     THIS GUIDELINE ON OUR ASSEMBLY DRAWINGS BUT DO NOT USE THE REVISION 
     LETTER,IT BEING UNDERSTOOD THAT THE LATEST REVISION OF THE DOCUMENT IS 
     TO BE USED.
                                        BEST OF LUCK

I have an engineer calling out IPC-A-610-B on a drawing.  Is this legit and 
if it is what is the B for?  Issue?
