MIL-PRF-12048E
4.5.1.2 Fuel Sampling. Fuel sampling shall be conducted in accordance with ASTM D 4057,
using the tube sampling procedure. Missing components or supplies required for the test, failure
to complete, or inability to collect sample of specified volume (see 3.3.1a) shall constitute failure
of this test. The equipment and materials needed to complete this test shall be recorded.
4.5.1.3 Free water and particulate contamination in distillation fuels. The test shall be
conducted in accordance with ASTM D 4176, Procedure 1, with a known test sample. Missing
components or supplies required for the test or failure to complete shall constitute failure of this
test. The equipment and materials needed to complete this test shall be recorded.
4.5.1.4 Flash point by Pensky-Martens closed tester. The test shall be conducted in
accordance with ASTM D 93 with a known test sample. Missing components or supplies
required for the test, failure to complete, or deviation of a test value from any other test value
greater than that cited in the repeatability section of ASTM D 93 shall constitute failure of this
test. The equipment and materials needed to complete this test shall be recorded.
4.5.1.5 Distillation of petroleum products. The test shall be conducted in accordance with
ASTM D 86 with a known test sample. Missing components or supplies required for the test,
failure to complete, or deviation of a test value from any other test value greater than that cited in
the repeatability section of ASTM D 86 shall constitute failure of this test. The equipment and
materials needed to complete this test shall be recorded.
4.5.1.6 Consumables. The recorded equipment and materials as a result of the tests from
4.5.1.1 to 4.5.1.5 shall be extrapolated to determine whether it meets the requirements to perform
initial sampling and at least 10 repetitions of the required tests (section 3.3.1).
4.5.2 Environmental.
4.5.2.1 High Temperature - Storage. The test kit, with the container closed, shall be subjected
to a high temperature environment of 63 ± 1 °C for 4 hours, after an initial period of 6 hours at 49
± 1 °C. Raising and lowering of the temperature shall be accomplished within a period of 1 hour,
for a total cycle time of 12 hours. A minimum of seven cycles (84 hours) is required. At
completion of the last cycle, adjust chamber air temperature to 20 ± 1 °C and maintain until
temperature stabilization of test kit has been achieved. The test procedures outlined in 4.5.1.3
and 4.5.1.4 shall be conducted. In addition to the conformance criteria cited therein, the kit case
and packing material shall be examined for deterioration, brittleness, or cracking. Functional
failure of the kit components, case, or packing material, or inability to perform tests, or satisfy test
precision criteria shall constitute failure of this test.
4.5.2.2 High Temperature - Operational. The test kit, with the container open, shall be
subjected to a high temperature of 50 ± 1 ºC for a period of 4 hours. The test procedures
outlined in 4.5.1.3 and 4.5.1.4 shall be conducted, while the temperature is maintained at 50 ±
1 °C. In addition to the conformance criteria cited therein, functional failure of the kit
components, inability to perform the tests or satisfy test precision criteria shall constitute failure of
this test.
4.5.2.3 Low Temperature - Storage. The test kit, with the container closed, shall be subjected
to a low temperature environment of -33 ± 1 °C for a period of 48 hours. At the end of this
