Standard Test Method for Determination of Fuel Filter Blocking Potential of Biodiesel Fuel Blendstock (B100) by Cold Soak Filtration Test (CSFT)

Importancia y uso:

5.1 Some substances that are soluble or appear to be soluble in biodiesel fuel blendstock (B100) at room temperature will, upon cooling to temperatures above the cloud point or standing at room temperature for extended periods, come out of solution. This phenomenon has been observed in both B100 and biodiesel blends. These substances can cause filter plugging. This method provides an accelerated means of assessing the presence of these substances in B100 and their propensity to plug filters.

5.1.1 Biodiesel fuel blendstocks that yield short filtration times are expected to give satisfactory operation of biodiesel blends at least down to the cloud point of the biodiesel blends.

5.2 The test method can be used in specifications as a means of controlling levels of minor filter plugging components in biodiesel and biodiesel blends.
