| 1. Expressed in milligrams per kilogram or parts per million; metals, like vanadium, nickel, iron, sodium; also, calcium, zinc and phosphorous, which are indicators of used lube oil in the fuel, which may increase the particulate emission and the risk of exhaust gasway fouling. |
| A. water |
| 2. It is expressed in square millimetres per second (or Centistokes) at a stated temperature; it is a measure of a fuel’s resistance to flow. |
| B. sediment |
| 3. It is expressed as per cent by volume; it may cause corrosion in the fuel system. |
| C. flash point |
| 4. It is expressed in degrees centigrade; it must be known for safe transport and storage |
| D. cat fines |
| 5. It contributes to air pollution; its compounds may corrode cylinder liners and piston rings. |
| E. elements |
| 6. It consists of hydrocarbon sludge and is contained in all fuels; it is a parameter (Total sediment potential) that is used to indicate and assess the stability and cleanliness of a fuel. |
| F. pour point |
| 7. Small particles of the catalyst (aluminium and silica oxides) used in the refi ning process and carried over into the residual fuel; they are porous, extremely hard, of irregular shape and abrasive in nature. |
| G. density |
| 8. It is expressed in degrees centigrade; is max 30°C; the lowest temperature at which the fuel will flow; wax will form at lower temperatures; wax may block filters or deposit on heat exchangers. |
| H. viscosity |
| 9. It is expressed in kilograms per cubic metre; it mainly affects the fuel separation. |
| I. carbon residue |
| 10. It is expressed as per cent by weight; it indicates the coke-forming tendencies of a fuel. |
| J. sulphur |
