Diesel exhaust fluid (e.g. AdBlue) testing according to ISO 22241

Diesel exhaust fluid (DEF) is an additive used in diesel-powered vehicles to help the catalytic reduction of nitrous oxides. Thus, the use of AdBlue and other exhaustive fluids improves ambient air quality. DEF testing package according to ISO 22241:2019 includes the measurements listed below: · Urea content (ISO 22241-2C) · Density at 20 °C (EN ISO 12185) · Refraction index at 20 °C (ISO 22241-2C) · Alkalinity as NH₃ (ISO 22241-2D) · Biuret (ISO 22241-2E) · Aldehydes (ISO 22241-2F) · Insoluble matter (ISO 22241-2G) · Phosphate (ISO 22241-2H) · Determination of Al, Ca, Cr, Cu, Fe, K, Mg, Na, Ni, and Zn content (ISO 22241-2I)
