MIL-PRF-25604F
mouth bottles intended for sampling shall be specially cleaned and handled according to the procedure
described in ASTM D2276 Section 10 with the exception listed in 4.3.4d of this specification.
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 to ensure that the
material conforms to 3.4. The examination shall be conducted after a representative aliquot of the
sample has been transferred to a clear glass vessel and compared to the same type vessel containing
the same volume of purified water.
4.3.2 Uns-dimethylhydrazine assay, water and amines. The UDMH, water and amine content of
the sample shall be determined by the Gas Chromatographic method described in Appendix A.
4.3.3 N-nitrosodimethylamine. The NDMA content of the propellant shall be determined by the
method described in Appendix B.
4.3.4 Particulate. The propellant sample shall be tested gravimetrically for particulate
contamination in accordance with ASTM D2276, with the following exceptions:
a. Mix the sample thoroughly without exposure to air. Immediately pour 500 mL of the sample
into a clean 500 mL graduated cylinder. Use this 500mL of propellant for the particulate analysis.
b. Pass the 500 mL sample aliquot through a Mitex disc polytetrafluoroethylene (PTFE)
hydrophobic, 10 µm, 0.47 mm diameter, white filter or equivalent.
c.
The oven temperature shall be set at 70°C (158°F).
d. Filtered American Chemical Society (ACS) reagent grade isopropyl alcohol shall be used for
rinsing the sample bottle and filter holder instead of petroleum ether specified in ASTM D2276. Use a
suitable solvent resistant filter disc with an absolute rating of at least 1.0 µm. Wet the filter with the
filtered isopropyl alcohol prior to filtering the sample.
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.
