Standard Test Method for Determining Water Separation Characteristics of Aviation Turbine Fuels by Portable Separometer.
Get more information about the standard at ASTM D3948-22
ASTM D3948 is a standard test method for determining the water separation characteristics of aviation turbine fuels using a portable separometer. Water contamination in aviation turbine fuels is a critical concern, as the presence of water can lead to engine corrosion, microbial growth, fuel filter clogging, and other performance issues. This method provides a way to assess how well aviation fuels separate water under specified conditions, ensuring that the fuel meets safety and performance standards for aviation operations.
Details
ASTM D3948 focuses on evaluating the ability of aviation turbine fuels to separate from water when subjected to certain conditions, using a portable device known as a separometer. The key components of the test include:
- Test procedure: The sample of aviation turbine fuel is mixed with water and then placed into the separometer, which is designed to allow the water to separate from the fuel under controlled temperature conditions of 49°C (120°F). The test measures how quickly and efficiently the water separates from the fuel, which reflects the fuel’s ability to perform effectively in aircraft engines where water contamination is a concern.
Industries and Applications
ASTM D3948 is widely used for several industries:
- Aviation industry: Commercial airlines, military aviation, and private aviation use this test method to ensure that the fuels used in their aircraft meet the necessary water separation requirements, preventing the risks associated with water contamination such as fuel filter clogging, corrosion, and microbial growth
- Fuel production and refining: Refiners and fuel blenders use this method to verify the quality of aviation turbine fuels they produce. Meeting ASTM D3948 ensures that the fuel can be used safely in aviation engines, free from excessive water contamination
- Aircraft maintenance and safety: Maintenance teams and engineers in the aviation industry rely on ASTM D3948 to test aviation fuels before refueling aircraft, ensuring that water contamination does not compromise engine performance or safety
- Military aviation: Military aviation services use this test to ensure that the fuel used in military aircraft is free from harmful water contamination, which is crucial for mission-critical operations and aircraft reliability
