PHOSPHORUS DETERMINATION IN PETROLEUM PRODUCTS: GENERAL
PHOSPHORUS DETERMINATION IN PETROLEUM PRODUCTS: GENERALDepending upon the product, phosphorus can serve as a beneficial adjunct or as a deleterious agent. Phosphorus in gasoline will damage catalytic converters used in automotive emission control systems, and its level therefore is kept low. In additives ...

PEROXIDE NUMBER OF PETROLEUM WAX: ASTM D1832
PEROXIDE NUMBER OF PETROLEUM WAX: ASTM D1832EXPLANATIONDeterioration of petroleum wax results in the formation of peroxides and other oxygen-containing compounds. The peroxide number measures those compounds that will oxidize potassium iodide. Thus the magnitude of the peroxide number is an indication ...
-
PEROXIDE NUMBER OF AVIATION TURBINE FUELS: ASTM D3703
PEROXIDE NUMBER OF AVIATION TURBINE FUELS: ASTM D3703EXPLANATIONThe magnitude of the peroxide number is an indication of the quantity of oxidizing constituents present in the sample. Deterioration of turbine fuel results in the formation of the peroxides and other oxygen-carrying compounds. The peroxide ...

PEROXIDES IN BUTADIENE: ASTM D5799
PEROXIDES IN BUTADIENE: ASTM D5799EXPLANATIONDue to inherent danger of peroxides in butadiene, specification limits are usually set for their presence. Butadiene polyperoxide is a very dangerous product of the reaction between butadiene and oxygen that can occur. The peroxide has been reported to be ...

PARTICULATE CONTAMINATION IN AVIATION FUEL: ASTM D2276
PARTICULATE CONTAMINATION IN AVIATION FUEL: ASTM D2276(Equivalent Test Method: IP 216)EXPLANATIONThis test method uses a field monitor. Two methods are described. One measures gravimetrically. The other uses a color rating technique for rapid qualitative assessment of changes in contaminant level without ...
