  • COPPER IN JET FUELS BY GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY: D6732 COPPER IN JET FUELS BY GRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY: D6732EXPLANATIONAt high temperatures aviation turbine fuels can oxidize and produce insoluble deposits that are detrimental to aircraft propulsion systems. Very low copper levels in excess of 50 μg / kg can significantly accelerate ...
  • COOLING CHARACTERISTICS OF QUENCH OILS BY COOLING CURVE ANALYSIS: D6200 COOLING CHARACTERISTICS OF QUENCH OILS BY COOLING CURVE ANALYSIS: D6200EXPLANATIONThis test method provides a cooling time versus temperature pathway which is directly proportional to physical properties such as the hardness obtainable upon quenching of a metal. These results may be used as a guide in ...
  • CONRADSON CARBON RESIDUE COKING VALUE OF TAR AND PITCH: D2416 CONRADSON CARBON RESIDUE COKING VALUE OF TAR AND PITCH: D2416EXPLANATIONThis test method is useful for indicating the relative coke-forming propensities and for evaluating and characterizing tars and pitches. This test method can also be used as one element in establishing the uniformity of shipments ...
  • CONRADSON CARBON RESIDUE OF PETROLEUM PRODUCTS: D189 CONRADSON CARBON RESIDUE OF PETROLEUM PRODUCTS: D189(Equivalent Test Methods: IP 13, ISO 6615, DIN 51551, JIS K 2270, and AFNOR T60-116)EXPLANATIONThe carbon residue value of burner fuel serves as a rough approximation of the tendency of the fuel to form deposits in vaporizing pot-type and sleeve-type ...
  • CONGEALING POINT OF PETROLEUM WAXES AND PETROLATUM: D938 CONGEALING POINT OF PETROLEUM WAXES AND PETROLATUM: D938(Equivalent Tests: IP 76, ISO 2207, and AFNOR T60-128)EXPLANATIONCongealing point is a wax property of interest to many petroleum wax consumers. This procedure measures the temperature at which a sample being cooled develops a "set" or resistance ...
  • CONE PENETRATION OF PETROLATUM: D937 CONE PENETRATION OF PETROLATUM: D937(Equivalent Tests: IP 179, DIN 51580, and AFNOR T60-119)EXPLANATIONPetrolatum is a purified mixture of semi-solid hydrocarbons obtained from petroleum and is often described as an unctuous mass. Cone penetration is a means of measuring the firmness of consistency of ...
  • CONE PENETRATION OF LUBRICATING GREASE: D1403 CONE PENETRATION OF LUBRICATING GREASE: D1403(Equivalent Tests: IP 310 and AFNOR T60-140)EXPLANATIONSee discussion under Test Method D217. The current method is intended for use only when the size of the sample is limited. Precision is better in the full scale method.These test methods include procedures ...
  • CONE PENETRATION OF LUBRICATING GREASES: D217 CONE PENETRATION OF LUBRICATING GREASES: D217(Equivalent Test Methods: IP 50, ISO 2137, and AFNOR T60-132)EXPLANATIONCone penetration test provides one measure of the consistency of a grease. These tests cover the full range of NLGI numbers from 000 to 6. They also evaluate the consistency of stiff greases ...
  • COLOR BY AUTOMATIC TRISTIMULUS METHOD: D6045 COLOR BY AUTOMATIC TRISTIMULUS METHOD: D6045EXPLANATIONDetermination of the color of petroleum products is used mainly for manufacturing control purposes and is an important quality characteristic because the color is readily observed by the user of the product. In some cases the color may serve as an ...
  • COLOR SAYBOLT COLOR: D156 COLOR SAYBOLT COLOR: D156(Equivalent Test Methods: DIN 51411, JIS K 2580, and AFNOR M07-003)EXPLANATIONSaybolt Color - An empirical definition of the color of a clear petroleum liquid based on a scale of -16 (darkest) to +30 (lightest). The number is derived by finding the height of a column of the sample ...
