Cloud Point |
The D2500 Cloud Point method determines the temperature at which fuel particles begin to visibly form a cloud of crystalline fuel molecules, but fuel flow is not yet completely restricted. For diesel and diesel blends, the Cloud Point gives an indication of where the Cold Filter Plug Point (D6371) may be, which is typically only a few degrees lower than the Cloud Point. At the Plug Point temperature, fuel flow is restricted. This test is suitable for biodiesel, diesel, and diesel blends.

Water and Sediment |
The D2709 Water & Sediment method is used to measure the amount of visible water, sediment, and suspended matter in fuel oils such as diesel and biodiesel. The D1796 Water & Sediment method is more appropriate for heavier petroleum products like oil. These methods do not detect entrained water; the D6304 Karl Fischer moisture titration is more suitable for entrained water.

Density by Digital Density Meter |
The D4052 Density method measures the density of liquids. Standard density measurements are generally taken at 15.6°C and several measures of density can be obtained. Density is the mass per unit volume of fuel and is typically reported as g/mL. Relative Density and Specific Gravity are the same measurement and is the density of the fuel divided by the density of water at the same temperature. This value is unitless. API gravity is a calculated measure of density where low API indicates a high-density fuel and high API indicates a low-density fuel.

Relative Density and Specific Gravity are the same measurement and is the density of the fuel divided by the density of water at the same temperature. This value is unitless.
