From Testing to Tailored Solutions – Your Journey Begins Here.

Guardianship from Refinery to Tank

Beyond certification, we perform diesel fuel testing throughout the supply chain, ensuring quality from refineries to pipelines and storage tanks. Contact us to discuss your fuel testing options and safeguard your critical applications.

About our diesel testing services:

The ASTM specification that covers the requirements for the seven different grades of diesel fuel used in various types of diesel engines is ASTM D975. We are equipped to run all tests related to this method for low sulfur (LSD) and ultralow sulfur (ULSD) No. 1 and No. 2 diesel fuels.

We perform diesel fuel testing for refineries, pipelines, nuclear power plants, fuel distributors, gas stations, truck and heavy equipment fleet owners, diesel engine repair shops, those who utilize emergency generators and fire pumps, insurance companies, and individual vehicle owners. While we can perform the full slate of testing for formal ASTM D975 certification, we work with all of our customers to choose the appropriate scope of testing that best meet their needs.  

Diesel storage for mission-critical applications, such as backup generators and fire suppression systems at nuclear power plants, hospitals and data centers, are checked frequently to ensure that the fuel will be suitable for use when needed. Fuel distributors and consumers rely on the refiners and pipelines to deliver high-quality fuel, but still need testing when problems, such as contamination or unexpected fuel system damage, are identified.  

Diesel has much better storage stability properties compared to gasoline. Nevertheless, the fuel can undergo important changes during storage that can compromise the fuel system. Water is commonly found in diesel storage tanks, especially those that are exposed to large temperature variation, such as outside storage tanks. The tanks must “breathe” to allow for the fuel to expand and contract with changes in temperature. This allows moist air to enter the tank, where it condenses and the water falls to the bottom of the tank. Over time, a significant amount of water can accumulate in this fashion, which promotes corrosion and microbial activity.

The following is a list of the common diesel tests we run. If you don’t see a test that you’re interested in, please contact us. We are always adding capabilities, willing to set up new methods, and have a large network of labs to collaborate with.
