MIL-DTL-46162E
operability limit depends on the vehicle fuel systems design (filter and pump locations, filter size
and porosity, proximity to engine heat, etc.) as well as other fuel properties. Most vehicles will
operate satisfactorily down to approximately the cloud point of the fuel, but some vehicles may
be equipped with fuel heaters which enable them to operate well below the cloud point. If fuel
waxing causes operability problems at or near the cloud point, type II referee fuel should be
used.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. Type of referee fuel (see 1.2).
c. Issue of DoDISS to be cited in the solicitation, and if required, the specific issue of
individual documents referenced (see 2.2.1 and 2.3).
d. Location and injection method for addition of electrical conductivity additive, fuel
system icing inhibitor and corrosion inhibitor, as required (type II referee fuel only)
(see 3.2.1.2 and table II).
e. Level of packing required (see 5.1).
f. Size and type of container required (see 5.1).
g. Quantity required and size containers desired.
6.3 Definitions.
6.3.1 Referee grade fuel. It is fuel representing the minimal or marginal quality level which
can be procured under specification A-A-52557 or MIL-DTL-83133 while meeting all of its
requirements. The referee grade diesel fuel (type I) is designed to be equivalent to the quality of
OCONUS distillate production or that production available in times of national emergency. It is
used for research ground turbine engines development and verification testing to assure that all
diesel-consuming equipment will perform adequately with all fuels procured under A-A-52557
or MIL-DTL-83133. The referee grade turbine fuel (type II) is designed to maximize the efforts
of lower viscosity, lower flash point, and lower cetane quality when used as intended. It is not
intended to be a substitute for the referee JP-5/JP-8 ST fuel under MIL-DTL-5624.
6.4 Safety.
6.4.1 Material Safety Data Sheets (MSDS). Contracting officers should identify those
activities requiring copies of completed MSDSs prepared in accordance with FED-STD-313.
The pertinent Government mailing addresses for submission of data are listed in FED-STD-313;
and 29 CFR 1910.1200 requires that the MSDS for each hazardous chemical used in an operation
must be readily available to personnel using the material. Contracting officers will identify the
activities requiring copies of the MSDS (see 3.4).
6.5 Reports. Reports are not requirements of this specification but may be requested in the
contract or work order.
