I found the following:

Jedec:
 Jedec 95-1, "Jedec Design Standard, Design Requirements for Outlines of Solid
State and Related Products"
JESD22 B-108, "Coplanarity Test for Surface-Mount Semiconductor Devices"

IPC:
IPC-7095, "Design and Assembly Process Implementation for BGAs"
(ot sure if it has been finalized yet)
