q
4. 8.1.2.4.1 Test performance. The chamber air will be
,
controlled to the specified ambient temperatures with all temperatures
monitored and recorded. With the FCC-FTS placed in the temperature/
altitude chamber and connected as specified in paragraph 4.5.2.1.5?
determine initial conditions as outlined in 4.5.2.1.6.2.
4. 8.1.2.4.2 Standard conditions (reference) . With the chamber
door open and the FCC-FTS exposed to room ambient conditions, the
FCC-FTS shall be turned on and operated in accordance with the
functional tests of paragraph 4.7. The functional performance of the
FCC-FTS shall be checked with warmup times not exceeding 10 minutes
and the input voltages to the FCC-FTS set at:
a.
Nominal 28 VDC
High 30.8 VDC
b.
Low 25.2 VDC
C.

The multi-point temperature recorder shall be on and recording the
chamber wall and air temperatures and the thermally instrumented
component temperatures wi thin the FCC-FTS throughout all temperature/
altitude tests. Record the results of the above tests on the
applicable data sheets.
