4. 8.1.5.3 Test setup FCC-FTS. The test setup shall simulate
handling, transportation, and service use. The FCC-FTS undergoing
test and the shock fixture shall be securely attached to the shock
machine carriage using the normal mounting attachment points.

test.
4. 8.1.5.4.1 Equipment shock. With the FCC-FTS non-operatingr
it shall be subjected to three shocks in each of two places in each
of the three mutually perpendicular axes. The sequence of test may
be in any order.

period, and waveform) shall be monitored for each shock, however
only one photograph of the shock spectrum need be made to assure
proper system performance and calibration. During the shock test
there is no requirement for functional performance. After each
series of shocks in each plane, the FCC-FTS mounting attachment
points shall be examined for evidence of mechanical failure. After
the completion of all 18 shocks (3 axes x 2 planes x 3 shocks each)
the FCC-FTS shall be carefully examined for evidence of mechanical
failure with all covers open. The test results shall be recorded on
the applicable data sheet.
4.8.1.5.5 Post shock oPeration. At completion of test, the
test set shall be operated per paragraph 4.5.1 and inspected and
results entered on the data sheets.
