Jet Fuel Analysis

Peak Petroleum Testing Services, Inc. built its reputation providing high service-oriented jet fuel analysis. All levels of commercial and governmental aviation turbine fuel handling personnel have come to rely on our high level of responsive service.

The scientists of Peak Petroleum Testing Services, Inc. have over 40 years of combined experience accommodating special schedules. We understand pipeline schedules change. Customers may need night, weekend, and or holiday analysis and we have provided those special levels of service for our entire history. We are ready to serve the needs of your testing requirements backed by our experience and accreditation.

We provide all the necessary testing required to verify that your jet fuel meets all relevant quality specifications.

In the United States, commercial aircraft use Jet-A as specified by ASTM D1655. Military aircraft uses other jet fuel grades, including JP-4 (older aircraft), JP-5, JP-7 (high-altitude aircraft), and JP-8.

We can perform jet fuel testing for airports, refineries, pipelines, FBOs, the US military, and individual aircraft owners. We have tested jet fuel for many years and provide fast, accurate results with a quick turnaround time, usually within the same day.

Certifying jet fuel before using it in any aircraft is crucial to ensure long-term safety and equipment reliability. As an example, the freezing point of jet fuel is critical for trans-polar and high-altitude flights.

High-temperature stability is tested using the JFTOT instrument per ASTM D3241 (Jet Fuel Thermal Oxidation Test) to ensure that fuel doesn't leave deposits on the turbine's combustion parts.

Also, any water found in the fuel may separate during the flight and cause it to freeze (due to low temperatures at high altitudes). This, in turn, can block the fuel inlet pipes and cause fuel starvation.

There are many alternative jet fuel blends currently in development that are not widely used in the commercial market at this time. We can perform testing on alternative and or traditional jet fuel.

Our basic aviation fuel test package helps determine whether your fuel meets standard ASTM D1655 Commercial JetA Fuel, or D910 Aviation Gasoline specifications. Our long-term storage testing package helps predict your product's remaining service life and product cleanliness, as well as determining if your fuel product meets aviation fuel specifications.

We also offer comprehensive testing packages for biodiesel, diesel Fuels, and marine bunker fuels.
