Diesel Emissions Fluid (AdBlue) Testing

Diesel Exhaust Fluid (DEF, AdBlue, Diesel Emissions Fluid) quality control testing per ISO 22241-1.

Diesel Emissions Fluids (DEF) are tested for quality specifications and potential contamination in Europe and North America. Often referred to as AdBlue® in European and other markets, DEF is required by many modern diesel engine applications using selective catalytic reduction (SCR) technology to reduce the levels of oxides of nitrogen emitted by an exhaust system.

SCR systems are part of the engine powertrain configuration, and contaminants or impurities in the Adblue or DEF could cause the SCR system to malfunction or fail. Thus, it is important to maintain DEF quality standards as characterized in the ISO 22241-1 standard. Intertek provides a full range of prompt DEF testing and analysis conforming to industry standards.

Full specification testing is performed on a real time turnaround to allow for fast efficient movement of product without impacting the deliverability of these products for our clients to the supply chain. The full specification service provided includes the following parameters.
