Introduction
This document contains requirements regarding equipment for railway vehicles and railway
infrastructure for filling railway vehicles with a NOx reduction agent AUS 32 (32 % aqueous urea
solution) as specified in ISO 22241-1:2019, hence forward referred to as AUS 32. These minimum
requirements describe the target system to be available across Europe to assist use of the railway
network.
The urea solution (AUS 32) as referred to in this document is commercially available and may exist under
various trade names. Trade names of products commercially available include: AdBlue®, ARLA 32®,
DEF, etc.
NOTE This information is given for the convenience of users of this document and does not constitute an

4 Requirements
4.1 System requirement
Railway vehicles fitted with an internal combustion engine that uses AUS 32 shall either have:
1) pumped refilling system with mechanical and electrical couplings and storage tank on the railway
vehicle compliant with 4.2. This is intended to permit routine regular refilling of the AUS 32 tanks on
the vehicle without the need for constant attendance by servicing personnel;
or
2) manual top-up system that informs the user that AUS 32 requires refilling, and a tank provided to be
refilled, as set out in 4.4, similar to systems used on road vehicles and construction machinery.
It is permitted to also fit additional alternative refilling connections to suit local servicing requirements.
Designated refilling points on railway infrastructure that store and dispense AUS 32 shall be fitted with
at least one mechanical and electrical coupling compliant with 4.3.1. It is permitted to also fit additional
alternative filling couplings to suit local conditions at the fuelling point where alternative AUS 32
couplings are fitted to the vehicles serviced in this location.
Mobile refilling equipment to dispense AUS 32 shall be fitted with couplings compliant with 4.3.1 or
suitable for use with the open system described in 4.4.
4.2 On vehicles
4.2.1 On board AUS 32 system
The AUS 32 system from the inlet up to and including the storage tank shall be able to withstand the
maximum pressure and flow rate shown in 4.3.2.
All parts of the AUS 32 storage tank and pipework on the vehicle that come into contact with the AUS 32
shall be chemically and structurally stable under known service conditions and shall be corrosion free.
Materials likely to come into contact with the AUS 32 shall be resistant to attack by the AUS 32.
4.2.2 Mechanical coupling for AUS 32 fluid supply
Vehicles shall be fitted with the male part of a self sealing coupling compliant to NATO STANAG-3756,
with a nominal diameter of 25 mm, type DDC 1 inch, in a material that does not react with AUS 32, such
as inox or hard alloy.
The connections shall be on each side of the vehicle between 600 mm and 1 600 mm above rail level,
measured to the centre of the connection. Where the connection is recessed from the vehicle bodyside
they shall not be recessed further than 100 mm deeper than the local bodyside. The connection shall have
space around it to allow removal of dust cap (whilst wearing thick gloves). A typical example of the
installed system is shown in Figure 1.
The connection on the vehicle shall have a dust cap that is capable of being removed without tools. It shall
be retained to the vehicle by flexible connection to prevent loss. It is recommended that the colour of the
dust cap should be blue.
In the immediate vicinity of the filling connection there shall be a label denoting “AUS 32” and/or
recognized trade name such as “AdBlue”, to clearly identify the use of the coupling.

4.2.3 Electrical connector for AUS 32 supply control circuit
An electrical connector shown in Annex A shall be fitted on each side of the vehicle (for the electrical
circuit shown in Figure 4). The electrical connection shall
