NOTICE
The following information is for reference and is to be used as a guideline
only.
There are many factors that determine DEF shelf life, with temperature and
duration being two of the major determining contributors. If in doubt, check the
concentration of the DEF. See the Test step in the Cummins Manual, or replace the
fluid with known quality DEF.
The following conditions are ideal for maintaining DEF quality and shelf life during prolonged
transportation and storage:
Ÿ
Storage temperature between 23°F and 77°F (-5°C and 25°C)
Ÿ
Store in sealed containers to avoid contamination
Ÿ
Avoid direct sunlight
In these conditions, DEF has a minimum expected shelf life of 18 months.
If stored at higher
temperatures for extended periods of time, the shelf life will be reduced by approximately 6 months for
every 5°C [9°F] above the highest storage temperature listed above.
DEF (DIESEL EXHAUST FLUID)
DEF is a critical element of the Tier 4 Final aftertreatment system.
DEF is used as a
consumable in selective catalytic reduction (SCR) in order to lower NOx concentration in the
diesel exhaust emissions from diesel engines. The DEF you purchase should meet and
display certification for one or more of the following standards:
Ÿ
American Petroleum Institute (API)
Ÿ
German Institute of Standardization DIN70700
Ÿ
International Organization of Standardization (ISO) 2224-1
Other common names:
Ÿ
Urea
Ÿ
AUS 32 (Aqueous Urea Solution 32)
Ÿ
AdBlue
Ÿ
NOx Reduction Agent
Ÿ
Catalyst Solution
Ÿ
It is unlawful to tamper with or remove any component of the
aftertreatment system.
It is also unlawful to use DEF that does not meet the
specifications provided or to operate the vehicle/equipment with no DEF.
Ÿ
DEF contains urea.
Do not get the substance in your eyes. In case of contact,
immediately flush eyes with large amounts of water for a minimum of 15
minutes. Do not swallow internally. In the event the diesel exhaust fluid is
ingested, contact a physician immediately. Reference the Materials Safety Data
Sheet (MSDS) for additional information.
See the Cummins Operation & Maintenance Manual for their DEF specifications.
Cummins
Inc. recommends the use of Fleetguard® Diesel Exhaust Fluid.
Ÿ
Never attempt to create diesel exhaust fluid by mixing agricultural grade
urea with water.
Agricultural grade urea does not meet the necessary
specifications required and the aftertreatment system may be damaged.
