Changes

Furnace burner manufacturers have expressed concerns with the stability of blends of biodiesel and middle distillate fuel. Poor oxidative stability of biodiesel blends can result in sediment formation and lacquering of furnace burner injection equipment. The inclusion of biodiesel in Type 2 heating fuel oil can degrade the storage stability of the finished fuel blend and long term storage (greater than 6 months) is not recommended. The impact of specific storage conditions has not been completely determined. The oxidation stability requirement of the B100 component is specified in [http://www.publications.gc.ca/site/eng/9.838093/publication.html CAN/CGSB-3.524].

'''9.4 Water and copper'''

<h5>9.4 Water and copper</h5>

Water in storage tanks and copper in the fuel supply system can increase the rate of fuel degradation in long term storage. Heating oil storage tanks should be clean and free of water to help avoid corrosion and microbial contamination (see C.4.3). Incorporating metal deactivator additives into the fuel can help to mitigate the effects of copper contamination.

'''9.5 Conductivity depletion'''

<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.
