It is necessary to add a tracer element to
AUS 32. Make sure that the SCR system
is not damaged by the quality of AUS 32
specified in the table and tracer element.
<Urea Crystallization issue during long
storage>
Following recommissioning procedure
is to part of operator manual/storage
instructions.
• The DEF tank must be filled to
maximum level before storage of
vehicle
• After the idle period and during
restart of the tractor, stored adblue
to be drained & the DEF tank should
be re-filled to maximum level and
then the tractor should be started.
Important information before storing
and restart after storing.
- Concentration of DEF must be more
than 32.5% As per regulation AUS 32 ISO
22241.
- Must make sure the battery is on for
more than 2 minutes until automatic
DEF withdrawal process is completed.
- DEF storing guidance is 2 months
under -40℃~40℃ (-40F~104F)and 4
months under -40℃~25℃(-40F~77F).
CAUTION
The condition of ISO 4259 within the
range should be applied in between the
maximum and minimum values. Also,
the minimum difference of 4 x R (R =
reproducibility of test method) should
be considered.
However, in order to keep the quality
high, 4 x R is not considered for the urea
concentration.
Values for the urea concentration,
density and refractive index are actual
values. (Refer to ISO 4259 for actual
values.)
The AUS 32 manufacturer produces
products based on the values for the
annotation a, d and e.
It is necessary to check if urea is
satisfied with the required
specifications.
The ISO 4259 conditions should be
applied.
