Generally, TERPS is the standard for Jepps, but if they are written to PANSOPS standards they say so on a plate, usually by the minima on approach plates. However, this is not the case for all of them - so beware.
But another method is to know what standard the country you are flying in uses.
The USA, Canada, Central and South America, Japan, Taiwan and Korea use TERPS. Everwhere els uses PANSOPS except for military airfields in the Phillipines and Thailand, although I think the Thai military may have just swapped over.
