3.5 Ownership and support requirements.
3.5.1 Endurance. The generator shall deliver sequentially, as shown, output for
1000 hours. During this time, it shall require no servicing or replacement of parts. The
generator shall subsequently meet the requirements of 3.3.2.1 (see 4.7.1).
3.5.2 Overspeed. The generator shall evidence no thrown solder, thrown impregnating
compound, damaged insulation, raised armature windings, raised commutator bars or other
damage. The generator shall subsequently meet the requirements of 3.3.2.1 (see 4.7.2).
3.5.3 Dielectric strength. The insulation shall evidence no loosening, cracking, charring,
burning, smoking or reduction of dielectric strength (see 4.7.3).
3.5.4 Surface finish. All exterior surfaces of the generator assembly shall be black in
color except the electrical connections, terminal box, and the extended shaft. No paint shall be
applied to mating surfaces on the frame or on the ends of the generator (see 4.7.4).
3.5.5 Safety
3.5.5.1 Asbestos, cadmium and hexavalent chromium. The generator shall not produce
any hazards to personnel or the environment resulting from the use of asbestos or cadmium.
Hexavalent chromium electroplating, coatings and finishes shall not be used (see 4.7.5.1).
3.5.5.2 Electrical connectors. The generator shall be free of rust, burrs, and scratches.
The connections shall have maximum bond from the soldering and/or brazing to the connectors
for resilience to vibration and shock to the generator (see 4.7.5.2).
3.5.6 Identification and marking. A nameplate shall be affixed to the exterior of the
generator frame in a location as specified on applicable drawings (see 3.4.1). Nameplates shall
conform to the non-dimensional requirements of A-A-50271 and shall include the following
minimum information (see 4.7.6):
a)
Generator, 28 Vdc
b)
300 Amperes
c)
Part or Identification number (see 6.6)
d)
National stock number
Manufacturer s identification
e)
Manufacturer s serial number
f)
3.6 Operating environmental requirements.
3.6.1 High temperature. The generator frame temperature shall not exceed
320 degrees Fahrenheit (F). The generator shall evidence no thrown solder, thrown
impregnating compound, damaged insulation, raised armature windings, raised commutator bars
or other damage. The generator shall subsequently meet the requirements of 3.3.2.1 (see 4.8.1).
