4.3.2 Testing. Unless otherwise specified by the procuring activity, tests as specified in 3.2 shall
be conducted in accordance with ASTM standards, using applicable methods as listed in Table I.
4.3.2.1 Water reaction. The water reaction test shall be conducted in accordance with ASTM D
1094, except that a 2-hour rather than a 5-minute standing period shall be used before evaluating the
propellant-water interface.
4.3.2.2 Thermal stability. The thermal stability test shall be conducted in accordance with (IAW)
ASTM D 3241 (JFTOT), as modified below. The heater tube shall be rated for deposits using the Alcor
Mark 8A Tube Deposit Rater (TDR) as modified in appendix A or the Alcor Mark 9 TDR (see 4.3.2.2.1b)
4.3.2.2.1 Test conditions.
a. Heater tube temperature at maximum point: 671°F
b. Fuel system pressure: 3.45 MPa (500 lbs/in2 of gravity)
c. Fuel flow rate: 3.0 mL/min
d. Test duration: 300 min
e. Quantity of test fuel: 1 L
4.3.2.2.2 Reported data. The following data shall be reported:
a. The maximum differential pressure across the test filter in 5 hours.
b. The maximum SPUN TDR rating (i.e. the maximum difference between the post-test
and the pretest TDR rating) reported in TDR units. Both before and after the JFTOT test, use the
modified Mark 8A or Mark 9 TDR to rate the heater tube at 2 mm increments from 20 mm to 50 mm along
the length of the heater tube.
4.4 Rejection and retest. When any sample of the propellant tested in accordance with 4.2 fails
to conform to the requirements specified herein, the entire lot represented by the sample shall be
rejected. Rejected material shall not be resubmitted without furnishing full particulars concerning
previous rejection and measures taken to overcome defects.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in
the contract or order (6.2). When actual packaging of materiel is to be performed by DoD or in-house
contractor personnel, these personnel need to contact the responsible packaging activity to ascertain
packaging requirements. Packaging requirements are maintained by the Inventory Control Point's
packaging activities within the Military Service or Defense Agency, or within the military service's system
commands. Packaging data retrieval is available from the managing Military Department's or Defense
Agency's automated packaging files, CD-ROM products, or by contacting the responsible packaging
activity.
