<h5>9.5 Conductivity depletion</h5>

<h5>9.5 Conductivity depletion</h5>

Due to the normal depletion of fuel oil conductivity during commingling, storage and distribution, or at low temperatures, the fuel oil should be sufficiently treated with conductivity-improver additive to ensure that the electrical conductivity requirement in 6.12 is met. The temperature at the point of use and the method of distribution could require a substantially higher conductivity level than 25 pS/m at the point of additive treatment. It should be noted that samples in clear bottles exposed to sunlight can also show a rapid depletion in conductivity. For more information, refer to ASTM D2624 and D4865.
