Diesel Exhaust Fluid (DEF) Testing is Now Available

POLARIS Laboratories® is excited to offer our customers testing and analysis for Diesel Exhaust Fluid (DEF).

DEF, also known as AUS 32 and marketed as AdBlue, is a water and urea mixture that is non-toxic, colorless and non-flammable. The aqueous urea solution is comprised of 32.5% urea and 67.5% deionized water.

Testing for DEF will include:

• Elemental analysis
• Visual examination
• % Urea
• pH
• Specific Conductance

Because DEF manufacturers perform specification testing following the ISO 22241 guidelines, POLARIS Laboratories® will not provide this testing.

Testing your DEF can identify concerns of contamination that can result in a decrease in engine performance capabilities. The above tests will provide a comprehensive check for contamination within the DEF in-service fluid. Including comprehensive testing will provide awareness and indicate actions required to maintain the engines’ proper performance.

As DEF is consumed by the engine, the fluid in the tank on the equipment will eventually be depleted and new fluid will be added. Addressing identified contamination concerns early will avoid potential future issues in the system.
