Not familiar with PP and RP
.40 and .60 are retention ratings for the amount of preservative held by the
wood... .40 being rated as "ground contact" and .60 for water contact
and mostly used in marine construction projects.
#2 is the grade of the lumber....This being the typical grade for most
framing lumber.
