MIL-DTL-83133H
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not
mandatory.)
6.1 Intended use. The fuels covered by this specification are intended for use in aircraft turbine
engines. JP-8 contains military unique additives that are required by military weapon systems. This
requirement is unique to military aircraft and engine designs. When authorized, JP-8 (F-34) may be used
in ground - based turbine and diesel engines. NATO F-35 is intended for commercial aviation, but can be
converted to JP-8 (F-34) by the addition of the appropriate additives.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, date of this specification, and grade (type) of fuel.
b. Quantity required and size containers desired.
c. Level of packaging and packing required (see 5.1).
d. Location and injection method for addition of electrical conductivity additive, fuel system icing
inhibitor and corrosion inhibitor, as required.
6.3 Conversion of metric units. Units of measure have been converted to the International
System of Units (SI) (Metric) in accordance with ASTM SI10. If test results are obtained in units other
than metric or there is a requirement to report dual units, ASTM SI10, should be used to convert the units.
6.4 Definitions.
6.4.1 Bulk lot. A bulk lot consists of an indefinite quantity of a homogeneous mixture of material
offered for acceptance in a single isolated container or manufactured in a single plant run through the
same processing equipment, with no change in ingredient material.
6.4.2 Packaged lot. A packaged lot consists of an indefinite number of 208-liter (55-gallon)
drums, or smaller unit packages of identical size and type, offered for acceptance and filled from an
isolated tank containing a homogeneous mixture of material; or filled with a homogeneous mixture of
material run through the same processing equipment with no change in ingredient material.
6.4.3 Homogenous product. A homogeneous product is defined as a product where samples
taken at various levels of the batch tank are tested for the defining homogeneous characteristics and all
values obtained meet the repeatability precision requirements for that test method.
6.4.4 Synthesized Paraffinic Kerosene (SPK) Kerosene consisting of n-paraffins, iso-paraffins
and cycloparaffins.
6.4.5 Fischer-Tropsch (FT) Process A catalyzed chemical process in which carbon monoxide
and hydrogen are converted into liquid hydrocarbons of various forms. Typical catalysts used are based
on iron and cobalt.
6.4.6 Hydroprocessed Esters and Fatty Acids (HEFA) SPKs. Synthetic Paraffinic Kerosene
produced by hydroprocessing plant, algal oils or animal fats.
6.4.7 Hydroprocessed or Hydrotreated Renewable Jet (HRJ) Terminology used to identify HEFA
SPKs.
