MIL-PRF-27404D
4.2.2 Rejection. When any sample of the propellant tested in accordance with 4.3 fails to
conform to the requirements specified herein, the entire lot represented by the sample shall be rejected.
4.3 Test methods.
4.3.1 Examination of product. The propellant shall be visually examined while performing test
specified in 4.3.4 to determine compliance with the requirement as specified herein. Examination to
ensure that the material conforms to 3.4 shall be conducted after the sample has been transferred to the
500 mL graduated cylinder.
4.3.2 Monomethylhydrazine (MMH) assay and water. The propellant and water content of the
sample shall be determined by one of the Gas Chromatographic (GC) methods described in Appendix A.
In case of a dispute, the packed column method (A.2.1) shall be the referee.
4.3.3 Non-volatile residue (NVR). The NVR of the propellant shall be determined in duplicate by
either of the methods described in Appendix B. In case of a dispute, the dropwise method (B.2.1) shall
be the referee.
4.3.4 Particulate. The propellant sample shall be tested gravimetrically for contamination in
accordance with ASTM D2276, with the following exceptions:
a. Mix the sample thoroughly by shaking the sample container. Immediately pour 500 mL of the
sample into a clean 500 mL graduated cylinder. Use this 500 mL of propellant for the particulate analysis.
b. Use a Mitex disc polytetrafluoroethylene (PTFE) hydrophobic, 10 µm, 0.47 millimeters (mm),
white filter or equivalent instead of that specified in ASTM D2276.
c. Set the oven temperature to 70°C (158°F).
d. Filtered American Chemical Society (ACS) grade isopropyl alcohol shall be used for rinsing
the sample bottle and filter holder instead of petroleum ether specified in ASTM D2276.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in
the contract or order (see 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.
6. NOTES
