Fuel Testing

Schedule 1 Fuel Testing

Schedule 1 Fuel Test gives a broad understanding of the condition of fuel and its suitability for use. It results in a basic fuel condition report.


  • A screening test to determine if there is a problem with the fuel
  • Useful for determining compliance with Australian Standard AS3570 or, if water and/or sediment accumulation are suspected as the likely cause of performance problems or component damage.

Schedule 2 Fuel Testing

Schedule 2 Fuel Test provides a relatively detailed fuel condition report. This test gives the user a clear understanding of the condition of their fuel and its suitability for use.


  • More comprehensive than a Schedule 1 Test.
  • Also provides a microscopic identification of sediment for possible sources of contaminant.
  • It also measures bacterial / fungal growth that may cause filter blockage and performance problems.

Schedule 3 Fuel Testing

Schedule 3 Fuel Test provides the most comprehensive fuel condition report available.


  • Provides a complete analysis of the condition of fuel and its suitability for use
  • Allows a clear understanding of whether the fuel can be treated or requires disposal
  • A quality check for conformance with AS3570 for fuel sale
  • This schedule will provide a definite conclusion on the fuel’s fitness for use
  • Identifies the causes of performance problems (low power, smoking, component damage etc)
  • Indicates poor fuel quality due to contamination by light or heavy grade products such as kerosene, solvents, petrol, wax, oil etc.

Analysis Methods associated with Testing Levels

Nata Accredited
Level 1
Level 2
Level 3
Appearance Yes ASTM D4176 A quick indicator of water or dirt contamination in the fuel Yes Yes Yes
Colour Yes ASTM D1500 Diesel is naturally coloured. Changes may indicate ageing or contamination Yes Yes Yes
Particulate Contamination Yes OL1003 Particulates contribute to fuel system blockage and faulty injector operation Yes Yes Yes
Filter Blocking Tendency Yes ASTM D2068 Indicates how quickly filter may become blocked Yes Yes Yes
Moisture Content Yes ASTM D6304A Moisture contributes to fuel system blockage, faulty injector operation and promotes fungal growth Yes Yes Yes
Density Yes ASTM D4052/D1298 Density is an indicator of contamination Yes Yes Yes
Bacterial/Fungal Growth OL1056 Fungal growth contributes to fuel blockages, faulty injector operation and promotes corrosion Yes Yes
Flash Point Closed Cup Yes ASTM D93 Flash point helps indicate type and degree of contamination Yes
Distillation Range Yes ASTM D86/D2887 Distillation range helps indicate type and degree of contamination Yes
Cloud Point Yes ASTM D2500 The temperature at which wax crystals form. It is a measure of fuel cold weather properties Yes
Calculated Cetane Index Yes ASTM D4737 Measures how easily diesel fuel ignited. High index generally indicates smoother combustion with less smoke Yes
Biodiesel Content/Infrared Scan OL1087 Measures the amount of biodiesel present, if any, in the fuel. The infrared scan also helps identify any contaminants present Yes
