A little background on what this table is telling us:
NFPA 77 classifies flammable liquids as Conductive, Semi-Conductive, and Non-Conductive:
Conductive Liquids = >10,000 pS/m
Semi-Conductive Liquids = >100<10,000 pS/m
Non-Conductive Liquids = <100 pS/m
In the tables below, 1 conductivity unit (C.U.) = 1 picosiemen per meter (pS/m)
