The specifications for European Proofs can be found at C.I.P.
Here is the link with some examples.

Commission International Permanente ( CIP )

http://www.cip-bobp.org/

Cartridge page pages

.45 Colt = http://www.cip-bobp.org/homologation/en/tdcc_public?page=4&cartridge_type_id=4

.44-40 = http://www.cip-bobp.org/homologation/en/tdcc_public?page=6&cartridge_type_id=2

.38-40 = http://www.cip-bobp.org/homologation/en/tdcc_public?page=5&cartridge_type_id=2


From the pages;

.45 Colt =    M = 12.5   PT max = 1100      PK = 1265   PE = 1430
.44-40   =   M = 17.5   PT max = 1100       PK = 1265   PE = 1375     EE =  890 
.38-40  =   M = 17.5   PT max = 1150     PK = 1323   PE = 1440     EE =1945   

It looks like a typing error for the .45 Colt and it should be;  PE = 1375

CUP psi

.45 Colt =    PT Max = 15954 psi    PK =  18347 psi   PE =  19942 psi
.44-40   =     PT Max = 15954 psi    PK =  18347 psi   PE =  19942 psi
.38-40   =     PT Max = 16679 psi    PK =  19188 psi   PE =  20885 psi


PT max     = maximum average pressure (bar)
PK         = 1,15 Pmax = maximum statistical individual pressure (bar)
PE      = 1,25 Pmax = mean proof pressure (bar)
M      = location of the pressure take (mm)
EE       = proof kinetic energy (Joule)
Notice: For conformal or tangential transducers the location (M) is that defined by the manufacturer.

One bar = 14.503778 psi
One gram = 15.4323584 grains

Useful case capacity in cc

.45 Colt    = 1.93 cc
.44-40      = 2.07 cc
.38-40      = 2.13 cc
