Oil & Petroleum Testing


Techniques that separate and arranges according to size, ferrous wear particles from a lubricant for analysis with a microscope. The Ferro gram provides information for the identification of wear particle types and a description of the wear mode that generates the particles.
Test Method:ASTM D 7690 


Viscosity is one of the most important properties of a lubricant as it determines both the film thickness of the oil and how readily the lubricant will flow into the narrow area separating the moving metal parts.
Test Method: ASTM D 445

Flash point:

The primary use of this method is for viscous materials (excluding fuels) having flash points of 79C and above. This test determines the temperature at which the oil will form a flammable mixture with air. The flash point can be compared with standard specifications to determine if the oil meets the specification. It is often used as an indicator of fuel dilution.
Test Method: ASTM D 3828

Fire point:

The fire point is a measure of the tendency for the oil to support combustion.
Test Method:ASTM D1310-14

Cloud point:

The cloud point defines the temperature at which wax crystals appear in the fuel upon cooling. The cloud point of a fuel and its impact on cold flow properties should be monitored to ensure trouble-free operation in cold climates.
Test Method:ASTM D2500 – 17a


Density is a fundamental physical property that can be used in conjunction with other properties to characterize both the light and heavy fractions of petroleum and petroleum products. Determination of the density or relative density of petroleum and its products is necessary for the conversion of measured volumes to volumes at the standard temperature of 15°C.
Test Method:ASTM D792 -13

Pour point:

This test helps in determining the lowest temperature at which movement of the fuel is observed. The pour point of a petroleum product is an index of the lowest temperature of use for certain applications.
Test Method:ASTM D58532-17A

Conardson carbon residue (CCR):

This test helps in determining the amount of carbon residue left after evaporation of an oil and to indicate relative coke-forming propensities. This test method is generally applicable to relatively nonvolatile petroleum products which partially decompose on distillation at atmospheric pressure.
Test Method: ASTM D189

Water & sediments:

This test helps in determining the volumetric percent of water and sediment in middle distillate fuels. Water and sediment in a fuel oil can cause fouling of the fuel-handling facilities, obstruct fuel flow and cause internal corrosion.
Test Method:ASTM D 1796

Acid number (TAN):

This test helps in determining the acidic or basic constituents in petroleum products and lubricants soluble or nearly soluble in mixtures of toluene and isopropyl alcohol.
Test Method:ASTM D664

Base number (TBN):

This test helps in determining the measure of the amount of basic substances in the oil always under the conditions of the test. It is sometimes used as a measure of lubricant degradation in service. However, any condemning limit shall be empirically established.
Test Method: ASTM D4789 – 17

Neutralization value:

This test helps in determining the Value that expresses the weight in milligrams of an alkali needed to neutralize the acidic material in one gram of oil. The neutralization number of oil is an indication of its acidity.
Test Method:ASTM D1534 – 95

Sulphur content:

This test helps in determining the instrumental determination of sulfur content in samples of carbon black feedstock oils. Values obtained represent the total sulfur content.
Test Method: ASTM D7679,ASTM D4294 – 16E1

Distillation range:

This test helps in determining the atmospheric distillation of petroleum products using a laboratory batch distillation unit to determine quantitatively the boiling range characteristics of such products as light and middle distillates, automotive spark-ignition engine fuels with or without oxygenates (see Note 1), aviation gasolines, aviation turbine fuels, diesel fuels, biodiesel blends up to 20 %, marine fuels, special petroleum spirits, naphthas, white spirits, kerosines, and Grades 1 and 2 burner fuels.
Test Method: ASTM D1078 – 11

Aniline point:

This test helps in determining the characterization of pure hydrocarbons and in the analysis of hydrocarbon mixtures. These test methods cover the determination of the aniline point of petroleum products and hydrocarbon solvents.
Test Method: ASTM D611 – 12

Cetane number:

This test helps in determining the measure of a fuel’s ignition delay; the time period between the start of injection and the first identifiable pressure increase during combustion of the fuel. In a particular diesel engine, higher cetane fuels will have shorter ignition delay periods than lower cetane fuels.
Test Method: ASTM D613 – 18a

Copper strip corrosion:

This test helps in determining the the corrosiveness of fuels and oils to copper. The test is designed to assess the relative degree of corrosivity of a petroleum product.
Test Method: ASTM D849-15

Wear metals – Ca, Mg, Na, K, Mo, Cu, Cr, Zn, P, Ba, B, Al, Pb, Mn, Ni, Si, V, Sn, Ag, Fe etc.:

This test helps in determining the expensive damage and downtime to high value engines, gears, generators, turbines and other important equipment. Early detection of wear metals in lubricants can improve machinary reliability, especially if done as part of a professional oil condition monitoring program.
Test Method:ASTM D 5185
