MIL-DTL-87173 Propellant, Priming Fluid, Alcm Engine, Grade Pf-1This specification covers one grade of high-density hydrocarbon fuel. This specification was thoroughly reviewed as a part of acquisition reform. While most of the requirements were converted to performance terms, due to the military-unique nature of the product \(see 6.1\) and the need for compatibility with deployed systems it was determined that not all requirements could be converted. The issuance of this specification as "detail" is not intended to constrain technology advances in future systems.

APPENDIX C

C.3.1.6 Integrator. An electric integrator is required for highest accuracy and precision. Data

acquisition and reduction by an on-line computer, programmed for gas chromatography, is convenient

and may be used if such capability is available.

C.3.1.7 Microsyringe. A microsyringe or auto sampler, capable of delivering sample volumes from

0.5 to 5.0 microliters, is required.

C.4 REAGENTS AND MATERIALS

C.4.1 Stationary-phase. The capillary column is described in C.3.1.5.

C.4.2 Carrier gas. Nitrogen gas with 1.406 Kg/cm2 (20 psi) head pressure shall be used.

C.4.3 Hydrogen. High purity, for flame ionization detectors

C.4.4 Air. Dry, filtered, and oil-free, for flame ionization detectors

C.4.5 Exo-tetrahydrodi(cyclopentadiene). (99 percent purity), hereafter referred to as JP-10

NOTE 2. High-purity samples of JP-10 may be obtained by submitting a written request to AFRL/PRSF,

1790 Loop Rd. N., Wright-Patterson AFB OH 45433-7103.

C.4.6 Methylcyclohexane. (99 percent purity) hereinafter referred to as MCH

C.4.7 n-Pentane, n-hexane, or carbon disulfide. Chromatographic purity.

C.4.8 Qualitative calibration mixture. A series of known hydrocarbons is used to calculate column

resolution. Prepare a mixture that contains about one percent (by volume) each, in pentane, hexane, or

carbon disulfide of at least two normal alkanes and two cycloalkane derivatives selected from highly-pure

(minimum 99 percent) samples which have boiling points in the 70�C-250�C range. The mixture must

contain MCH, n-dodecane, and n-tetradecane.
