3.8.5
Quantity and Types of Special Test Cable Assemblies - The type design
and quantity of special test cable assemblies shall be determined by the contractor and subject to
the approval of the Bureau of Aeronautics. The types and quantities shall be minimized . Cable
assemblies normally provided with test equipment shall not be included
3. 9
Characteristics of Power Control and Overload Protective Devices.
39.1
Function - The power control and overload protective devices shall provide
a means to introduce control and protect the source of operating power,
3. 9.2
Control - It shall be possible to disconnect completely all operating power.
This shall include disc-rig of ground return conductors. This control shall be centralized
at a single location and preferably it shall be possible to accomplish this control with a single
switching action.
3. 9,3
Overload Protection - Circuit breakers or fuses shall be provided to
disconnect operating power in the event of electrical load in excess of normal. Such overload
protection shall be in accord with the general requirements of Specification MIL-E-5400. Such
overload protection shall be designed to prevent damage to both the equipment being tested and
the source of operating power.
3.10
Characteristics of Test Points
3. 10.1
Function - The test points shall provide for electrically connecting test
equipment to the equipment for the purpose of
(a) determining the characteristics of electrical signals within the
equipment and /or
(b) introducing test signals into the equipment.
High Voltage Test Points - No test points shall be provided for measuring
3. 10.2
potentials in excess of 1000 V. Provisions shall be made such that all high voltages may be
measured at a potential level of less than 1000 volts.
3. 10.3
Connectors - Connectors for milliammeter or voltmeter measurements
shall accommodate test prods in accordance with the requirements of Specification MIL-E-5400.
Connectors for other than milliammeter and voltmeter measurements shall be in accordance with
Specification MIL-C-5015.
Mounting Provisions - Test points will be secured to a structural member of
3. 10.4
the test bench harness or shall be designed to allow mounting to a workbench as required in 3.1.3.1.
3.11
Characteristics of Cooling Devices
Function - Cooling devices shall provide for maintaining the temperature
3. 11.1
of equipment within its normal operating range.
3. 11,2
Type - These devices shall consist of electric motor driven air blowers with
suitable ducts included to direct the cooling air stream
Operating Power - The electic motors shall operate from 103, 5 to 126 5
3 11.3
volts rms. 54-66 cps a. c. power.
3. 11.4
Mounting Provisions - The cooling device shall be designed to be mounted
either on a structural member of thee test bebench harness or on a workbench as per 3. 1.3 1.
