ASTM International develops fuel standards to ensure quality, safety, and proper performance in engines. These standards cover gasoline, diesel fuel, jet fuel, and ethanol, as well as test methods for properties such as distillation, vapor pressure, and sulfur content.

Some key standards include:

• D4814 for gasoline

• D975 for diesel fuel

• D1655 for conventional jet fuel

• D7566 for sustainable aviation fuel (SAF)

In addition, there are numerous test methods, such as D86 for distillation and D5453 for sulfur content.

These globally recognized standards play a crucial role for producers, refineries, and regulatory agencies.
