bond, or other damage in the molded section or adjacent portion of the cable jacket. Following
3.9.3 Thermal shock. After being subjected to the test specified in 4.6.3, the assembly
shall not exhibit any physical damage. Following the test, the cable assembly shall meet the
3.9.4 Moisture resistance (cable assemblies with watertight connectors). After testing as
specified in 4.6.4, there shall be no visual evidence of blistering, corrosion, or exposure of the
base metal of the connector, degradation of elastomers or separation of bonded materials.
Following the test, the cable assemblies shall meet the requirements of 3.7.2.
3.9.5 Conductor insulation overcure (molded or heat-cured potted cable assemblies only).
The insulation of each conductor within any portion of the cable jacket encased by a molded
crotch, molded termination, or molded section shall be tested for overcure. The percent
elongation shall be not less than 90 percent of the minimum unaged elongation requirement of the
appropriate Government-approved material specification as tested under method 3031 of
FED-STD-228.
3.9.6 Bend relief flexibility (flexible molded cable assemblies with bend reliefs only).
The cable assembly shall be subjected to the test specified in 4.6.6. There shall be no bond
separation or cracking between the bend relief and the cable jacket, connector housing, or back
3.9.7 Vibration. The cable assembly shall be tested as specified in 4.6.7. There shall be
no evidence of bond separation at the cable jacket or connector, nor loosening of component parts
or other mechanical fastening device from the mating receptacle. Following the test, the cable
3.9.8 Ozone resistance (molded rubber only). Cable assemblies with molded rubber shall
be tested for ozone resistance as specified in 4.6.8. At the completion of the exposure period,
there shall be no evidence of cracking in the bend relief or cable jacket when examined under
7X magnification.
3.9.9 Cable re-verification. The test shall be performed on cable manufactured 12 months
prior to the date of shipment of the cable assembly to the government, and the test specimen shall
meet the unaged elongation requirements listed in the applicable Government-approved material
specification selected by the manufacturer. The cable shall be tested in accordance with 4.6.9,
except that benchmarks shall be 2 inches apart, flat, and smooth steel grips of the self-aligning
type may be used. The elongation after aging shall be based on the benchmarks applied before
aging.
3.9.10 Durometer hardness. The durometer hardness Shore "A" of a molded termination
and other molded sections shall be measured as specified in 4.6.10 and shall be not less than
50 Shore "A" durometer or as specified on the drawing or in the contract (see 6.2).
