ELECTRICAL CONDUCTIVITY OF LIQUID HYDROCARBONS: ASTM D4308
EXPLANATION
This test method applies to the determination of the "rest" conductivity of aviation fuels and other similar low-conductivity hydrocarbon liquids in the range 0.1 to 2000 pS/m. This test method can be used in the field or in a laboratory.
TEST SUMMARY
A sample of liquid hydrocarbon is introduced into a clean conductivity cell which is connected in series to a battery voltage source and a sensitive dc ammeter. The conductivity, automatically calculated from the observed peak current reading dc voltage and cell constant using Ohm's law, appears as a digital value in either a manual or automatic mode of meter operation.
TEST PRECISION
The precision statement was developed on samples in the range 0.1 to 2000 pS/m in an auto mode instrument. The bias of this test method has not been measured.
