MIL-DTL-6162C
within one year of the date of manufacture. This requirement shall in no way prejudice the Government's position
with respect to any other warranty stated or implied under the terms of the contract.
4.3 Disassembly and inspection. Each machine shall, following completion of all qualification tests, be
disassembled and inspected for conformance design requirements and to assure there has been no excessive wear or
other defects effecting reliability. Additional disassembly and inspection shall be as required by the individual tests
specified herein.
4.4 Acceptance.
4.4.1 Acceptance requirements. Generators and starter-generators produced under this specification will be
accepted if:
a. Qualified to this specification as amended by the associated specification sheet and if the qualification
is sustained in conformance with paragraph 4.2.2.
b.
Acceptance tests of Table I are successfully completed.
c. Installation instructions approved by the qualifying activity are securely attached to each machine in
such a way that they need not be removed for check out of the machine prior to its installation on the aircraft.
d. A package holding one nut for each mounting hole in the generator flange is securely attached to each
generator in such a way that it need not be removed for check out of the machine prior to installation on the aircraft.
e.
All changes to equipment have been processed in accordance with MIL-STD-973, as applicable.
4.5 Test Conditions. Unless otherwise specified, each test required by Table I shall be made under the
following conditions.
4.5.1 Mounting. The machine shall be mounted on a suitable test stand. The rotational axis of the machine
shall be horizontal.
4.5.2 Excitation. The machine shall be self-excited and controlled by suitable variable resistance or regulator
in series with the shunt field. The shunt field current shall not be considered as part of generator load current.
External excitation shall not be required in meeting test requirements.
4.5.3 Ambient temperature. Unless otherwise specified herein, test ambient temperature shall be 25° C ± 0.5°
C (77° F ± 0.9° F). Examination of product shall be conducted at room ambient temperature.
4.5.4 Altitude. Unless otherwise specified herein, the tests shall be run at approximately sea level altitude.
4.5.5 Location of load. The electrical load for generator operator operation shall be so located that it will not
appreciably affect the ambient or the blast cooling air temperatures.
4.5.6 Warm-up. Except as noted herein, prior to each test the machine shall be operated as a generator at the
specified continuous operating speed, rated load, and rated voltage for sufficient time to reach a substantially
constant temperature. Warm-up shall be completed when the shunt field temperature does not increase more than 1°
C above the then existing ambient temperature during a period of five minutes. Readings shall be taken at intervals
not in excess of two minutes.
4.5.7 Voltage measurement. When operating as a generator, voltage shall be measured between terminals E
(negative) and B (positive).
