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.

REQUIREMENTS

3.1 Materials. Except as otherwise specified herein, the priming fluid shall consist completely of a

mixture of exo-tetrahydrodi(cyclopentadiene) and methylcyclohexane.

3.1.1 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or

environmentally preferable materials should be used to the maximum extent possible, provided the

material meets or exceeds the operational and maintenance requirements, and promotes economically

advantageous life cycle costs.

3.2 Chemical and physical requirements. The chemical and physical requirements of the priming

fluid shall conform to those listed in table I.

3.2.1 Additives. The additives listed shall be used in combination in amounts not to exceed those

specified. Information concerning the type and amount of each additive used shall be made available

when requested by Procuring Activity or User.

3.2.2 Antioxidants. The following active inhibitors shall be blended separately or in combination into

the priming fluid in total concentration of 90 parts per million (minimum) to 110 parts per million

(maximum), by weight, not including weight of solvent, in order to prevent the formation of polymeric

oxidation products:

a. 2,6-di-tert-butyl-4-methylphenol

b. 6-tert-butyl-2,4-dimethylphenol

2,6-di-tert-butylphenol
