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 JP-4 and JP-5 fuels covered by this
specification are intended for use in aircraft turbine engines. These fuels
require military unique additives that are necessary in military weapon
systems. This requirement is unique to military aircraft, engine designs, and
missions. Additionally, JP-5 is a military unique fuel because it must have a
flash point substantially higher than commercial aviation turbine fuels. It is
stored in large quantities on aircraft carriers and other vessels. The flash
point is for safety in these military unique applications.
6.2 Acquisition requirements. Acquisition documents
should specify the following:
| a. |
Title, number, and date of this specification |
| b. |
Grade of fuel required (see 1.2) |
| c. |
Information concerning the type and amount of each
additive used (see 3.3) |
| d. |
Location and injection method of the corrosion
inhibitor/lubricity improver (see 3.3.3) |
| e. |
Location and injection method of the fuel system
icing inhibitor (see 3.3.4) |
| f. |
Location and injection method of the static
dissipater for JP-4 only (see 3.3.5) |
| g. |
Quantity required and size containers desired |
| h. |
Packaging requirements (see 5.1) |
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 Material Safety Data Sheets. Contracting officers
will identify those activities requiring copies of completed Material Safety
Data Sheets prepared in accordance with FED-STD-313. The pertinent Government
mailing addresses for submission of data are listed in FED-STD-313.
6.5 Sample containers. A number of jet fuel properties
are very sensitive to trace contamination from sample containers.
6.6 Definitions.
6.6.1 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.
6.6.2 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 the
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.
6.6.3 Homogeneous 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.
6.7 Subject term (key word) listing.

6.8 International standardization agreements. This
specification implements ASCC Air Std 15/6, Guide Specifications (Minimum
Quality Standards) for Aviation Fuels: NATO F-34, F-35, F-40 and F-44; ASCC
Air Std 15/9, Interchangeability Chart of Standardized Aviation Fuels,
Lubricants and Associated Products; NATO STANAG 1135, Interchangeability of
Fuels, Lubricants and Associated Products Used by the Armed Forces of the
North Atlantic Treaty Nations; and NATO STANAG 3747, Guide Specifications
(Minimum Quality Standards) for Aviation Turbine Fuels (F-34, F-35, F-40 and
F-44). When amendment, revision, or cancellation of this specification is
proposed, the preparing activity must coordinate the action with the U.S.
