ASTM D1796 Water And Sediment In Fuel Oils By The Centrifuge Method
The water and sediment content of fuel oil is significant because it can cause corrosion of equipment and problems in processing. A determination of water and sediment content is required to measure accurately net volumes of actual fuel oil in sales, taxation, exchanges, and custody transfers.

ASTM D2386 Automatic Freezing Point Of Aviation Fuel
The freezing point of an aviation fuel is the lowest temperature at which the fuel remains free of solid hydrocarbon crystals that can restrict the flow of fuel through filters if present in the fuel system of the aircraft. The temperature of the fuel in the aircraft tank normally falls during flight depending on aircraft speed, altitude, and flight duration. The freezing point of the fuel must always be lower than the minimum operational tank temperature

ASTM D5865 Bomb Calorimeter For Coal And Coke
The gross calorific value can be used to compute the total calorific content of the quantity of coal or coke represented by the sample for payment purposes. The gross calorific value can be used for computing the calorific value versus sulfur content to determine whether the coal meets regulatory requirements for industrial fuels. The gross calorific value can be used to evaluate the effectiveness of beneficiation processes

ASTM D86 Distillation Of Petroleum Products At Atmospheric Pressure
A 100-mL specimen of the sample is distilled under prescribed conditions for the group in which the sample falls. The distillation is performed in a laboratory batch distillation unit at ambient pressure under conditions that are designed to provide approximately one theoretical plate fractionation. Systematic observations of temperature readings and volumes of condensate are made, depending on the needs of the user of the data. The volume of the residue and the losses are also recorded

ASTM D3948 Water Separation Characteristics Of Aviation Turbine Fuels
This tester provides a measure of the presence of surfactants in aviation turbine fuels. it can detect carryover traces of refinery treating residues in fuel as produced. They can also detect surface active substances added to or picked up by the fuel during handling from point of production to point of use. Certain additives can also have an adverse effect on the rating. Some of these substances affect the ability of filter separators to separate free water from the fuel.

ASTM D613 Cetane Number of Diesel Fuel Oil
The cetane number of a diesel fuel oil is determined by comparing its combustion characteristics in a test engine with those for blends of reference fuels of known cetane number under standard operating conditions. This is accomplished using the bracketing handwheel procedure which varies the compression ratio (handwheel reading) for the sample and each of two bracketing reference fuels to obtain a specific ignition delay permitting interpolation of cetane number in terms of handwheel reading.

ASTM D7525， ASTM D7545 Rapid Small Scale Oxidation Stability Tester
A 5ml sample is introduced into a vessel which is then charged with oxygen to 500kPa at a temperature of 15 to 25℃. The test is initiated by starting the heater and heating the pressure vessel to a temperature of 140℃. The pressure is recorded continuously until the breakpoint is reached. Alternatively, the test maybe terminated when a predetermined minimum requirement is reached.
