IPC-SD-320 was canceled March 1992. It was superseded by IPC-RB-276, 
which was then superseded (in October 1996) by IPC-6012, the rigid board 
qualification specification.

I'm assuming IPC-A-6000 refers to the "0" revision of the standard; in 
other words, the original publication. If so, this was canceled in Sept. 
1979, and has been superseded several times. The current edition is 
IPC-A-600E, published in AUgust 1995. This is a pictorial representation 
of the requirements set forth in IPC-RB-276/IPC-6012.
