Diesel Exhaust Fluid (AdBlue) Testing

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

Diesel Exhaust Fluid (DEF) is often referred to as AdBlue® in Europe and other markets. AdBlue®/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.

AdBlue®/DEF is a very pure 32.5% urea solution and in easy to use. Diesel engines with SCR (Selective Catalytic Reduction) technology are able to reduce emissions of nitrogen oxides from diesel vehicles. The Nitrogen Oxide produced by a diesel engine will be converted into nitrogen and steam and as a result, it will reduce NOx emissions of diesel vehicles to 85%. We see SCR (Selective Catalytic Reduction) technology, in agricultural and forestry machinery, buses, and cars with diesel engines, trains, and in the shipping industry.

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