FUEL ANALYSIS TESTS
Micro-biological Test
Sterile membranes are used to filter the fluid and these are then placed on a suitable growth medium and allowed to incubate. After 5 days, they are assessed for growth.
TAN Total Acid Number
This test describes the measurement of the acidic constituents in oils and is reported in milligrams of potassium hydroxide per gram of sample.
Water by Karl Fischer
This test is used to determine the water content in petroleum products by automatic coulometric Karl Fischer titration, using an oven.
SEM
Debris to be analysed is placed in the SEM and bombarded with electrons which release X rays characteristic of the element that they hit. These X-rays are used to determine the elemental composition of the alloy.
Density or Specific Gravity
The sample is injected into an oscillating tube, the change in its oscillation is directly proportional to the Density of the fluid.
Lovibond Colour
This consists of the visual determination of colour in a variety of petroleum compounds such as lubricating oils, heating oils, diesel fuel oils etc. Results are reported as the colour of the sample and the designation of the glass producing a matching colour. ie 7.5 colour to ASTM 1500.
Micro Carbon Residue
This test determines the amount of carbon residue, in the range 0.10% to 30.0% m/m, left after evaporation and pyrolysis of petroleum products under specified conditions.
