Fuels testing is essential for ensuring quality, safety, and operational performance across aviation, automotive, industrial, and marine applications.
Our laboratory performs accredited fuels testing using ASTM and ISO methods listed within our ISO/IEC 17025:2017 scope, ensuring reliable and traceable results.
Aviation Fuel
Aviation fuels require strict verification of appearance and corrosion behaviour to ensure safety and proper handling.
Key Testing Parameters (Accredited):
- Appearance checks for free water, haze, or particulate matter (ASTM D4176)
- Copper corrosion rating to assess reactivity with system metals
- Colour determination using tintometer grading
- Density determination for quality control and specification alignment (ASTM D1298)
Gasoline
Gasoline requires monitoring of appearance, corrosivity behaviour, and compositional indicators to ensure product integrity and safe usage.
Key Testing Parameters (Accredited):
- Color determination using (ASTM D156)
- Copper corrosion rating to assess fuel–metal compatibility
- Refractive index for screening compositional shifts
- Appearance check for haze, water, or particulate contamination
- Conductivity measurement for handling and static safety (ASTM D2624)
Diesel
Diesel quality affects ignition reliability, storage stability, and fuel system cleanliness. Accredited testing supports contamination checks and specification verification.
Key Testing Parameters (Accredited):
