4.4.1.2
Operational Test:
Each equipment shall be operated long enough to permit the
equipment temperature to stabilize and to check sufficient
characteristics and record adequate data to assure satis-
factory equipment operation.
4.4.1.3
Manufacturing Reliability Test:
Each equipment shall be operated under the conditions speci-
fied herein for a period of 6 hours without failure. A
failure shall be defined as anything which causes malfunction-
ing of the equipment. Only those adjustments will be permitted
which can be made by using such controls and adjustments that
are accessible to the operator during the normal use of the
equipment.
Ambient room
Temperature
Ambient room
Humidity
Any selected frequency within the
Vibration
range of 20 to 30 cps (excluding
resonant points) and a minimum
amplitude of 3g's
The equipment shall be vibrated (without vibration isolators)
for a period of 10 minutes prior to the beginning of the 6-
hour period of operation. Where feasible, the equipment
shall be operated during this vibration period for the purpose
of detecting flaws and imperfect workmanship. Operation with-
in the specified limits of satisfactory performance is not
necessarily required during the vibration period. The direc-
tion of vibration should be vertical to the normal mounting
plane for 5 minutes and lateral to that plane for 5 minutes.
Where it is not feasible to vibrate the equipment in 2
directions the vertical direction shall be used. During the
6-hour period of operation following the 10-minute vibration
period, the equipment shall be mechanically cycled periodically
through its various phases of operation. 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 repetitive failures occur, corrective action shall be
taken to eliminate this defect from future equipment. A record
shall be kept of all failures. The 6-hour period specified
above may be composed of two 3-hour periods to conform with
standard working hours.
