Standard Specification for Aviation Turbine Fuels.
Get more information about the standard at ASTM D1655-24
ASTM D1655 is a widely recognized standard specification for aviation turbine fuels. It defines the requirements and specifications for kerosene-type aviation turbine fuels, including Jet A and Jet A-1. In summary, ASTM D1655 ensures the safety, reliability, and environmental compatibility of aviation turbine fuels, serving as a cornerstone for global aviation operations and fuel production.
Details
ASTM D1655 provides specifications for the chemical and physical properties of aviation turbine fuels to ensure their performance, safety, and compatibility with jet engines. It covers two main types of kerosene-based fuels:
- Jet A: Primarily used in North America.
- Jet A-1: Used internationally due to its lower freezing point, making it suitable for high-altitude operations.
Key properties evaluated under ASTM D1655 include:
- Volatility: Ensures proper vaporization for efficient combustion.
- Freezing Point: Defines the minimum operating temperature for high-altitude conditions.
- Flash Point: Ensures safety during storage and handling by preventing fire hazards.
- Density: Assessed to maintain fuel-to-air ratios in engines.
- Sulfur Content: Limited to minimize corrosive effects and emissions.
- Aromatic and Olefin Content: Controlled to improve combustion efficiency and reduce soot formation.
- Thermal Stability: Ensures the fuel’s resistance to decomposition at high temperatures, which is critical for engine cleanliness.
Compliance ensures the fuel meets international aviation safety and performance requirements.
Industries & Applications
ASTM D1655 is is widely applied in industries where aviation turbine fuels are used:
- Aviation industry: The standard is vital for commercial airlines, cargo carriers, and military aviation to ensure safe and efficient engine performance
