Diesel engines — NOx reduction agent AUS 32 — Part 1: Quality requirements

Moteurs diesel — Agent AUS 32 de réduction des NOx — Partie 1: Exigences de qualité

This edition has been replaced by ISO 22241-1:2019.

Abstract / scope

ISO 22241-1:2006 specifies the quality characteristics of the NOx reduction agent AUS 32 (aqueous urea solution) which is needed to operate converters with selective catalytic reduction, so-called SCR (Selective Catalytic Reduction) converters, in motor vehicles with diesel engines. SCR converters are particularly suitable for selectively reducing the nitrogen oxide (NOx) emissions of diesel engines.
