发布日期：2019-07

标准范围

本文件规定了符合ISO 22241-1的NOx还原剂AUS 32的重新加注接口，该接口是使用选择性催化还原（SCR）排气处理系统的转化器所需的。本文件规定了开放式加注系统的最低功能和几何要求，以确保车载加注系统和非车载加注系统之间的兼容性。附录a中提供了密封加注系统的兼容性条件。本文件适用于ISO 3833中定义的商用车辆和客车，其车辆总质量超过3.5 t，设计用于使用固定式车外加注系统。本文件也适用于固定式车外加注系统的喷嘴。注:在本文件中，术语“NOx还原剂AUS 32”缩写为“AUS 32”。

This document specifies the refilling interface for the NOx reduction agent AUS 32 in conformance with ISO 22241？1, which is needed to operate converters with a selective catalytic reduction (SCR) exhaust treatment system.This document specifies the minimum functional and geometric requirements of an open refilling system, in order to ensure compatibility between the on-board refilling system and the off-board refilling system. Compatibility conditions for a sealed refilling system are provided in Annex A.This document applies to commercial vehicles and buses as defined in ISO 3833 and having a gross vehicle mass of more than 3,5 t, designed to use stationary off-board refilling systems. This document also applies to the nozzle of stationary off-board refilling systems.NOTE Throughout this document, the term "NOx reduction agent AUS 32" is abbreviated to "AUS 32".
