MAINTENANCE
The condition of ISO 4259 within
the range should be applied in be-
tween the maximum and minimum
values. Also, the minimum differ-
ence of 4 x R (R = reproducibili-
ty of test method) should be con-
sidered. However, in order to keep
the quality high, 4 x R is not con-
sidered 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 pro-
duces products based on the val-
ues for the annotation a, d and e.
It is necessary to check if urea is
satisfied with the required specifi -
cations. The ISO 4259 conditions
should be applied.

ment to AUS 32. Make sure that the
SCR system is not damaged by the
quality of AUS 32 specified in the ta -
ble and tracer element.
