ASTM D2420 Hydrogen Sulfide In Liquefied Petroleum (LP) Gases
Liquefied petroleum gases and their products of combustion must not be unduly corrosive to the materials with which they come in contact. The potential personnel exposure hazards of H2S also make the detection and measurement of hydrogen sulfide important, even in low concentrations. In addition, in some cases the odor of the gases must not be objectionable

ASTM D7621 Apparatus for Hydrogen Sulfide in Fuel Oils
KN-7621 Apparatus for Hydrogen Sulfide in Fuel Oils conforms to ASTM D7621 Standard Test Method for Determination of Hydrogen Sulfide in Fuel Oils by Rapid Liquid Phase Extraction. A weighed test specimen is introduced into a heated test vessel containing a diluent base oil. Air is bubbled through the oil to extract the H2S gas. The air with the extracted H2S is passed, via a vapor phase processor (Procedure A only), to an H2S specific electro-chemical detector enabling the H2S content of the air to be measured and the amount in the liquid phase to be calculated in mg/kg/ The filter cartridge is not required for procedure B.

ASTM D4870 Total Sediment In Residual Fuels
Appreciable amounts of sediment in a residual fuel oil can cause fouling of facilities for handling, and give problems in burner mechanisms. Sediment can accumulate in storage tanks, on filter screens, or on burner parts, resulting in obstruction of the flow of oil from the tank to the burner

ASTM D3230 Salts In Crude Oil
KN-3230 Salt Content of Crude Oil Tester conforms to ASTM D3230 Standard Test Method for Salts in Crude Oil (Electrometric Method), it is suitable for the approximate chloride (salts) concentration in crude oil. The range of concentration covered is 0 to 500mg/kg or 0 to 150lb/1000bbl as chloride concentration/volume of crude oil. KN-3230 is suitable for measuring the salt content to detect the total halide value of which the range is 0.002~0.02%(weight) in the crude oil, reduced oil, cracking oil residue and fuel oil, it is also suitable for estimating the seawater pollution situation of the used team turbine oil and bunker fuel oil.
