Jack, IPC-4101 is in "Interim Final" circulation and when published 
should be adequate to handle both commercial and Mil-spec replacement 
callouts.  IPC-4101 will supercede IPC-L-108 (thin lam), IPC-L-109 
(prepreg), IPC-L-112 (composite lam)  and IPC-L-115 (rigid lam).  I hope 
that within one year it will also replace MIL-P-13949.

Regards
