Salient Characteristics for PATS-70A Cables The following cables are to be procured for the PATS-70A production effort:

The salient characteristics for hardware and construction of the above items are:

· MIL-STD-202G ELECTRICAL TESTING

· DIELECTRIC WITHSTANDING VOLTAGE 301 - 750VDC, ALL CONDUCTORS TO GROUND

· INSULATION RESISTANCE 302 - TEST B, ALL CONDUCTORS TO GROUND

· DC RESISTANCE 303 - CONTINUITY <2 OHM PER WIRING DIAGRAM

· ITEMS SHALL MEET MIL-PRF-28800F CLASS II SPECIFICATIONS

· MINIMUM QUALIFYING DESIGN MATERIALS:

· WOVEN HEATSHRINK FABRIC OVER SEAMLESS CONVOLUTED PTFE INNER TUBING

· INTERNAL KEVLAR STRAIN RELIEF MECHANICALLY ATTACHED TO CONNECTOR BACKSHELLS RELIEVING STRESS ON INTERNAL WIRES AND CONTACTS

· CRIMPED SLEEVE BACKSHELL ATTACHMENT TO CONDUIT TUBING AND OUTER SLEEVING

· FLOATING I.D. SLEEVE

· HARNESS CONSTRUCTION REQUIREMENTS

· WORKMANSHIP AND INSPECTION TO BE PERFORMED IAW IPC/WHMA-A-620B

· SOLDER ALL CONNECTIONS IAW IPC-J-STD-001, LEAD FREE SOLDER IS NOT ACCEPTABLE

· SERVICEABILTY – CONNECTORS, WHEN UNTHREADED, MUST EXTEND 1.5 TO 3.0 INCHES BEYOND THE BACKSHELL WITHOUT DAMAGE TO CONDUIT ASSY TO ALLOW FOR REPAIR

· PRINTED CIRCUIT BOARDS SHALL BE FABRICATED PER IPC-6011/6012 (LATEST REVISION) CLASS 2, UNLESS OTHERWISE NOTED AND SHALL BE FREE OF CHIPS, CRACKS, FOREIGN MATTER, AND DEFECTS WHICH WOULD IMPAIR THE MECHANICAL OR ELECTRICAL INSULATING AND CONDUCTING PROPERTIES Project testing requirements are:

· Environmental Testing: User Interface Cable Assembly, Interconnect Cable Assembly, and Auxiliary Facility Power Cable Assembly were used to qualify the PATS-70A for environmental ruggedness and must meet applicable requirements of MIL-STD-461F and MIL-PRF-28800F Class 2 utilizing test methods per MIL-STD-810G.

· Operational Testing: All cable P/N's have been extensively field tested by Air Force maintainers for suitability and ruggedness.

· Development Testing: All cable P/N's have been approved by the design authority for interconnection, form, fit, and function with the PATS-70A core and auxiliary units as well as the units under test.
