Dan,
You bring up a good question! Does IPC have an offical position on the
continued use of IPC-RB-276?
I hope others take up this discussion. I am somewhat out of my element
in this discussion, so I am very interested in how others view it. This
is my opinion on the situation.
I guess I don't understand what obsolete means. Does it mean that IPC
no longer prints and sells it? Does it mean that IPC can sue me and
make me take any reference to IPC-RB-276 off my drawing documents? If I
call out IPC-6011/2 today, how long until those busy bee's at IPC make
it "obsolete" ?
Basically, I do not give the IPC the authority to dictate what specs I
can and can not use in my drawings. I consider them private
communications between my company and my suppliers. (I may be dead
wrong.) I feel free to use whatever method of communications works
best. If I call out Mil-P-28809A, who really cares that it has been
cancelled? If I call it out in a contract, can't I still used it in a
court of law if a supplier is nonconforming?
Now, If the customer wants our drawing package to meet certain criteria,
ie all references be current at the time of release, then yes, we will
have to call out the IPC-6011/2. So yes, if the customers drawing
specification tells me I can't use IPC-RB-276, I would gladly comply,
and with a smile. But then I would also check to see that the customers
drawing spec has not been cancelled! (Rumor has it that one of the
drawing specs is/was/will be cancelled ... DOD-STD-100 ???)
Again this is my opinion, I do not even know for sure what the company
policy is, except to give the customer what they want. How do others
deal with the shifting sands of calling out requirements?

PS My modem is 14.4. I was going to upgrade until my son asked what was
out there on the web which I needed to get 3 time faster. After a short
discussion, we bought a mind numbing, stupid game, and I saved well over
$50. We sit playing this game for hours, and don't use the modem very
much. We are both very happy, however we have each lost at least 15 IQ
points.
