(b) Consist of nine motors.
(c) Be tested as specified in Section 4 herein and is for the pur-
pose of determining, prior to starting production, that the contractors
production methods are capable of yielding items that comply with the
technical requirements of the contract.
3.2 Basic requirements
3.2.1 Contractor-furnished data. No data is required by this specifica-
tion or by applicable documents referenced in Section 2 unless specified
in the contract or order (see 6.2).
3.2.2 Materials and treatments of materials and parts. Unless other-
wise specified in the contract or order, all materials and treatments
of materiels and parts used in the manufacture of the motor shall be in
accordance with the requirements specified herein and with the require-
ments and documents shown on the Specification Control Drawing 2540053.
3.2.3 Inspection and test equipment and facilities. The supplier shall
furnish and maintain all necessary inspection and test equipment facili-
ties, and shall provide personnel for performing all quality conformance
tests specified herein. The test equipment shall be adequate to permit
performance of the required quality conformance tests for the motor.
3.2.4 Dissimilar metals. Unless suitably protected against electrolyt-
ic corrosion, dissimilar metals shall not be used in contact with each
Dissimilar metals are defined in MIL-STD-89.
All solder connections shall be made in accordance with
3.2.6 Fungus proof material. Materials that are nutrients for fungi
shall not be used unless necessary. Where used and not hermetically sealed,
they shall be treated with a fungicidal agent.
3.2.7 Fuel comparability. The exterior of the motor may be exposed to
splashing by the torpedo propellant, a liquid fuel known as Otto Fuel
Composition II. This is a nitrate ester based propellant diluted with
straightchain hydrocarbons. The fuel is compatible with all metals and
with both silicone and fluorc carbon-based lubricants. The fuel is com-
patible with some nonmetals and incompatible, more or less, with others.
The approved nonmetallic materials are listed below.
(a) Fluorc carbons (Teflon and Kel-F)
