This document specifies the refilling interface for the NOx reduction agent AUS 32 in conformance with 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”.
