4.3.1.:
Manufacturing Run In Test - Each equipment shall be operated
under the conditions specified herein for a period of 6 hours without failure.
The equipment shall be attached to the RL-3G5A/ASQ-81(V) Reeling Machine and
power applied to the cable maintenance fixture for a period of 6 hours. The
reeling machine shall be cycled (OUT to cable limit and IN to speed-change
point) a minimum of 9 times with a minimum of 15 minutes OFF between
half cycle. . failure shall be defined as anything which causes malfunctioning

The equipment shall be vibrated for a period of 10 minutes prior to the
beginning of the 6-hour period of operation. The direction of vibration should
be vertical to the normal mounting plane. Should a failure occur, it should
be repaired and the test started over, except that the 10-minute vibration
period need not be repeated when it is certain the failure was not a result
of the vibration. Should repetition failures occur, corrective action shall
be taken to eliminate this defect f-em future equipment. A record shall be
kept of all failures. The 6-hours period specified above may be composed of
two 3-hour periods to conform with standar working hours.
4.3.2 Special Tests - Special tests shall be conducted on a
quantity of equipments or the purpose of checking the effect of any design
or material change on the performance of the equipment and to assure adequate
quality control Procuring activity shall make determination of need for
conducting special tests,

Special Test Schedule - Selection of equipments for special
tests shall be made as follows:
(1) Or an early equipment after engineering or
material change.
(2) Whenever failure reports or ether information
indicate additional tests are required. (This
will be determined by the procuring activity).
