To clarify, MIL-P-55110 was originally related to Printed Wiring Boards,
which is where the "P" came from. In the 1990s, the move was towards
performance based specifications rather than product based specifications.
The "PRF" you see in 55110 and 31032 stand for performance.

I'm not exactly sure if this is correct, but the military used to use a
letter in its specifications corresponding to the component type, e.g.,
Mil-R-6106 for Relays, Mil-M-38510 for Microcircuits, Mil-P-55110 for
Printed Wiring Assemblies. The PRF designation came about as the specs
changed to "performance" specifications as opposed to specific device
specifications.

Hi Franklin,
For what it's worth-
MIL-P-55110 Rev D, dated 12/31/84 was revised to MIL-PRF-55110 Rev E,
dated12/31/93. I don't know what the "P" and "PRF" denote.
Regards,
Mark Hargreaves

Can anyone tell me the difference between
MIL-P-55110
and
MIL-PRF-55110
Have a drawing where MIL-P-55110 is noted.
Thanks
Franklin
