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

Abstract / scope

This document specifies the quality characteristics of the NOx reduction agent AUS 32 (aqueous urea solution) which is needed to operate selective catalytic reduction (SCR) converter systems in motor vehicles with diesel engines. SCR converter systems are particularly suitable for selectively reducing the nitrogen oxide (NOx) emissions of diesel engines.
