Are you asking about the placards or placard boards?

The placard boards dimensions (16" x 24") and construction details for use on House Cars with steel ends or all steel construction were adopted as "Recommended Practice" by the MCBA in 1914.

"And when did the practice become formalized through a rule or recommended practice?"

See above.  The first formal requirements I have seen for the use of explosives placards was in 1908 from the Bureau of Explosives.  PRR and other railroads were using placards prior to that year.
