  • DENSITY AND RELATIVE DENSITY GRAVITY, SPECIFIC: ASTM D5002 DENSITY AND RELATIVE DENSITY GRAVITY, SPECIFIC: ASTM D5002EXPLANATIONThis test method covers the determination of the density or relative density of crude oils that can be handled in a normal fashion as liquids at test temperatures between 15 and 35° C. This test method applies to crude oils with high ...
  • DENSITY AND RELATIVE DENSITY REAL DENSITY OF CALCINED PETROLEUM COKE: ASTM D5004 DENSITY AND RELATIVE DENSITY REAL DENSITY OF CALCINED PETROLEUM COKE: ASTM D5004TEST SUMMARYThe mass of the sample is determined directly and the volume derived by determining the mass of liquid displaced when the sample is introduced into a pycnometer. Oil or other material sprayed on calcined petroleum ...
  • DENSITY, RELATIVE DENSITY, AND SPECIFIC GRAVITY VIBRATED BULK DENSITY OF CALCINE DENSITY, RELATIVE DENSITY, AND SPECIFIC GRAVITY VIBRATED BULK DENSITY OF CALCINED PETROLEUM COKE: ASTM D4292Vibrated bulk density (VBD) indicates the porosity of calcined petroleum coke, which affects its suitability for use in pitch-bonded carbon applications. This property is strongly dependent upon ...
  • REAL DENSITY OF CALCINED PETROLEUM COKE: ASTM D2638 REAL DENSITY OF CALCINED PETROLEUM COKE: ASTM D2638TEST SUMMARYA sample is dried and ground to pass a 75- μm screen. The mass of the volume is determined directly, and the volume derived by the volume of helium displaced when the sample is introduced into a helium pycnometer. The ratio of the mass of ...
  • DENSITY, RELATIVE DENSITY, AND SPECIFIC GRAVITY DENSITY, RELATIVE DENSITY, AND SPECIFIC GRAVITYGENERALDensity is an important property of petroleum products being part of product specifications. Materials are usually bought and sold on that basis or if on volume basis then converted to mass basis via density measurements. This property is almost synonymously ...
  • DEMULSIBILITY CHARACTERISTICS OF LUBRICATING OILS: ASTM D2711 DEMULSIBILITY CHARACTERISTICS OF LUBRICATING OILS: ASTM D2711EXPLANATIONThis test method provides a guide for determining the demulsibility characteristics of lubricating oils that are prone to water contamination and that may encounter the turbulence of pumping and circulation capable of producing water-in-oil ...
  • CRYSTALLINE SIZE OF CALCINED PETROLEUM COKE BY X-RAY DIFFRACTION: ASTM D5187 CRYSTALLINE SIZE OF CALCINED PETROLEUM COKE BY X-RAY DIFFRACTION: ASTM D5187EXPLANATIONCrystallinity of petroleum coke is a general measure of quality affecting suitability for end use and is a function of the heat treatment. The crystallite thickness is used to determine the extent of such heat treatment, ...
  • CORROSION-PREVENTIVE PROPERTIES OF LUBRICATING GREASES (EMCOR TEST): ASTM D6138 CORROSION-PREVENTIVE PROPERTIES OF LUBRICATING GREASES (EMCOR TEST): ASTM D6138EXPLANATIONThis test method is used to assess the ability of grease to prevent corrosion in rolling bearings operated in the presence of distilled water, NaCl solution, or synthetic sea water. It uses grease-lubricated ball ...
  • CORROSION-PREVENTING PROPERTIES OF LUBRICATING GREASES: ASTM D5969 CORROSION-PREVENTING PROPERTIES OF LUBRICATING GREASES: ASTM D5969EXPLANATIONThis test method differentiates the relative corrosion-preventive capabilities of lubricating greases under the test conditions using grease lubricated tapered roller bearings exposed to various concentrations of dilute synthetic ...
  • CORROSION PREVENTIVE PROPERTIES OF LUBRICATING GREASES: ASTM D1743 CORROSION PREVENTIVE PROPERTIES OF LUBRICATING GREASES: ASTM D1743EXPLANATIONThis test method differentiates the relative corrosion-preventing properties of lubricating greases using grease-lubricated tapered roller bearings stored under wet conditions. This test method is based on CRC Technique L 41 ...
