3.2 Hydrostatic pressure. The body and head shall withstand a hydrostatic pressure of 8,000
pounds per square inch (psi) for 15 seconds, minimum, without leaking, deformation, or mechanical
failure (see 6.3.1).
3.3 Structural strength. The assembled thruster shall withstand a static tensile force of
2,000 pounds, minimum, for 15 seconds, minimum, between mounting points without unlocking and
without mechanical failure (see 6.3.1).
3.4 Protective finish. Protective finish shall be in accordance with the applicable
specifications and drawings and shall apply to all surfaces of the component regardless of
configuration. Remanufactured exterior components (see 6.4 and 6.5) shall have the existing
protective finish stripped and the specified protective finish reapplied.
3.5 Residual magnetism. The metal parts assembly shall not deflect the indicator of the
compass more than five degrees in either direction using the procedures of 4.5.4.
3.6 Shear pin strength. The shear pin, after application of protective finish, shall shear
when a load of 48 ± 4 pounds is applied at the steady rate of 0.125 inch per minute.
3.7 Metal parts assembly. Parts shall be combined to produce an assembly which conforms to
the requirements of the metal parts assembly drawing. All threaded joints shall be assembled with
sufficient torque to bottom components.
3.7.1 Integrated plant products. When remanufacturing and loading of the assembly is
performed in an integrated plant, the metal parts assembly requirement may be waived and the
residual magnetism requirement performed on the loaded assembly only.
3.7.2 Threaded component parts. Class 2A or 2B thread gage shall be used on remanufactured
component parts inspection versus class 3A or 3B thread gage required on new hardware for
3.8 Workmanship. Thrusters shall be free of cracks, splits, or other defects which might
prevent proper mating with connecting parts or proper functioning of the device.
3.8.1 Metal defects. All components shall be free from cracks, splits, cold shuts,
inclusions, porosity, or any similar defect.
3.8.2 Burr. No part shall have a burr which might interfere with the assembly or function of
the item or which might be injurious to personnel handling the item.
3.8.3 Foreign matter. No part or assembly shall contain chips, dirt, grease, rust, corrosion,
or other foreign matter.
