  • ELECTRICAL CONDUCTIVITY OF LIQUID HYDROCARBONS: ASTM D4308 ELECTRICAL CONDUCTIVITY OF LIQUID HYDROCARBONS: ASTM D4308EXPLANATIONThis test method applies to the determination of the "rest" conductivity of aviation fuels and other similar low-conductivity hydrocarbon liquids in the range 0.1 to 2000 pS/m. This test method can be used in the field or in a laboratory.TEST ...
  • ELECTRICAL CONDUCTIVITY OF FUELS: ASTM D2624 ELECTRICAL CONDUCTIVITY OF FUELS: ASTM D2624(Equivalent Tests: IP 274, ISO 6297, and DIN 51412 T2)EXPLANATIONThe ability of a fuel to dissipate charge that has been generated during pumping and filtering operations is controlled by its electrical conductivity, which depends upon its ionic species content. ...
  • ELASTOMER COMPATIBILITY OF LUBRICATING GREASES AND FLUIDS: ASTM D4289 ELASTOMER COMPATIBILITY OF LUBRICATING GREASES AND FLUIDS: ASTM D4289EXPLANATIONMeasurement of changes in the volume and hardness of an elastomer that occur from immersion in a lubricating grease or fluid provide a means of evaluating relative compatibility. Much of this test method is derived from Test ...
  • DUST CONTROL MATERIAL ON CALCINED PETROLEUM COKE: ASTM D4930 DUST CONTROL MATERIAL ON CALCINED PETROLEUM COKE: ASTM D4930EXPLANATIONThe dust control material is applied to calcined coke to help maintain a dust free environment. It adds weight to the coke and can have a negative effect on the quality of carbon and graphite artifacts made from the treated coke. ...
  • DROPPING POINT OF LUBRICATING GREASE: ASTM D2265 DROPPING POINT OF LUBRICATING GREASE: ASTM D2265TEST SUMMARYA grease sample in a test cup is supported in a test tube placed in an aluminum block oven at a preset constant temperature. A thermometer is positioned in the cup so that it measures the temperature without coming in contact with the grease. ...
  • DROPPING POINT OF LUBRICATING GREASE: ASTM D566 DROPPING POINT OF LUBRICATING GREASE: ASTM D566(Equivalent Tests: IP 132 and ISO 2176)TEST SUMMARYThis test method is not recommended for temperatures above 288° C. In those cases, use Test Method ASTM D2265. A sample of lubricating grease contained in a cup suspended in a test tube is heated in an ...
  • DROPPING POINT DROPPING POINTGENERALThe dropping point is the temperature at which the grease passes from a semisolid to a liquid state. This change in state is typical of greases containing soaps of conventional types added as thickeners. These tests are useful in identifying the types of greases and for establishing ...
  • DIMETHYLFORMAMIDE OF TAR AND PITCH: ASTM D2764 DIMETHYLFORMAMIDE OF TAR AND PITCH: ASTM D2764EXPLANATIONThis test method is used in evaluating and characterizing tars and pitches and as one element in establishing the uniformity of shipments or sources of supply. It is a rapid and reasonably accurate measure of the toluene insoluble (TI) content ...
  • DISTILLATION OF PITCH: ASTM D2569 DISTILLATION OF PITCH: ASTM D2569EXPLANATIONThis test method for the distillation of pitch can be used when the amount of distillate below 270° C is <2 %.TEST SUMMARYA 100-g sample is distilled from an electrically heated flask in a shield at a designated rate. The weight of distillate fractions ...
  • DISTILLATION AT REDUCED PRESSURE: ASTM D1160 DISTILLATION AT REDUCED PRESSURE: ASTM D1160(Equivalent Test Method: ISO 6616)EXPLANATIONThis test method is used for the determination of the distillation characteristics of petroleum products and fractions that may decompose if distilled at atmospheric pressure. Both a manual and and an automatic method ...
