标准摘要
[中文适用范围]： 本文件规定了氮氧化物还原剂 AUS 32（尿素水溶液）的质量特性，该剂是在配备柴油发动机的机动车辆中运行选择性催化还原 (SCR) 转化器系统所需的。 SCR 转化器系统特别适合选择性地减少柴油发动机的氮氧化物 (NOx) 排放。 [外文原描述]： 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.
