Specifications and test methods for diesel fuel (normal and severe cold grades) (from the standard NF EN 590 see AFNOR information document M15-007 and M15-022). 

In drawing contracts and making acceptance tests, refer to the pertinent ASTM standards. ASTM Standards contain specifications (classifications) and test methods for burner fuels (D 396), motor and aviation gasolines (D 4814 and D 910), diesel fuels (D 975), and avia-...

Thomas and Delfino (1991) equilibrated contaminant-free groundwater collected from Cainesville, FL with individual fractions of three individual petroleum products at 24-25 °C for 24 h. The aqueous phase was analyzed for organic compounds via U.S. EPA approved test method 625. Average anthracene concentrations reported in water-soluble fractions of kerosene and diesel fuel were 12 and 25 pg/L, respectively. Anthracene was ND in the water-soluble fraction of unleaded gasoline. 

Although cetane engine testing has been used for many years to evaluate diesel fuels for their cetane number, confusion still exists with regard to this evaluation method. Problems associated with cetane number testing are usually attributed to the following ... 

The calculated cetane index methods were developed to help predict the fuel cetane number without extensive engine testing. Since the calculated cetane index is determined from physical property values such as the specific gravity and the 10%, 50%, and 90% distillation points, it is readily measurable from laboratory data. The ASTM methods D-976 and D-4737 are used to determine the diesel fuel cetane index. 

Other emulsion test methods are used to rate the ability of fuel to shed water. These methods include ASTM D-1401 and the Waring Blender Test. The ASTM D-1401 method is a lubricant test method, but has been adopted by the U.S. military for rating diesel fuel demulsibility.This method is summarized by ASTM as follows ... 

Additional low-temperature fuel filterability information is often required to confirm whether fuel will pass through fuel filters in cold environments. Two tests are commonly used to determine this performance value, ASTM D-4539 and IP 309. The method ASTM D-4539 is termed the Low-Temperature How Test (LIFT) and is used to determine the low-temperature filterability of diesel fuel.

Nitrated glycols, especially the lower members such as ethylene-, propylene, tri-ethylene-, and diethyleneglycol nitrates, are used in expl and proplnt compns. Nitrates of the higher glycols, or polyglycols, were proposed as ingredients of Diesel fuels in order to raise their "cetane number (See Vol 2 of Encycl, p C145-R Analysis and Test Methods. 

Standard test method for cold filter plugging point of diesel and heating fuels, ASTM Standard ASTM D 6371, ASTM International, West Conshohocken, PA, 2005. 

Cetane Number—The ignition quality of a diesel fuel measured using an engine test specified in ASTM Method D 613. Cetane number is determined using two pure hydrocarbon reference fuels cetane, which has a cetane rating of 100 and heptamethylnonane (also called isocetane), which has a cetane rating of IS [2.2].
