Force to engage and disengage:
Longitudinal force: 12 pounds maximum.
Torque: 4 inch-pounds maximum.
Coupling proof torque: 5 inch-pounds minimum.
Coupling mechanism retention force: 60 pounds minimum.
Ozone exposure: Not applicable.
-6
Pressure altitude: The pressure shall be 1 X 10 atmospheres and temperature shall be at the maximum operating
value. Connector attenuation increase shall not exceed 1 dB at any interval of the test.
Submersion: Not applicable.
Fluid immersion: Not applicable.
Durability: 200 cycles, 1 dB maximum change.
Low temperature: 1 dB maximum change.
Temperature life: For spaceflight parts, temperature life shall be in accordance with EIA-455-4, conditions 5 and F.
Four samples shall be tested for qualification inspection. No failures shall be allowed.
Plug accessories: Each plug shall be supplied with a minimum of one crimp ferrule as needed (see figure 1); two
alignment sleeves (see figure 2); one protective cable-end cap; one 1.5 inch length of heat-shrink tubing or one
rubber boot; and one set of assembly instructions. The assembly instructions shall include a listing of the epoxies
specified in this specification sheet and a cleaning procedure statement as follows:
Cleaning procedures: Dampen lens tissue (paper wipes or cotton swab) with a small amount of isopropyl
alcohol or water. Gently wipe the face of the connector, removing any debris, particularly around the optical fiber,
using clean lens tissue (paper wipes, cotton swab). Dry face of connector by blowing with dry air.
NOTE: The plug mates with MIL-C-83522/4 receptacle; MIL-C-83522/5 receptacle, MIL-C-893522/7 receptacle; MIL-
C-83522/8 receptacle; or a MIL-C-83522/3 adapter. Connection to any other type plug may result in excessive
coupling loss.
Group A testing: Group A testing for spaceflight parts shall consist of 100 percent testing of the parts.
Group B testing: For spaceflight applications, the sample size for group B testing shall be per table II. A sample of
parts shall be randomly selected from each lot in accordance with table II, if one or more defects are found, the lot
shall not be supplied to this document. In addition to tests listed in MIL-C-83522 (for group B inspection), the
following tests shall be performed.
Thermal shock: Four samples.
Temperature: Four samples.
Vibration: Four samples.
Tensile loading: Four samples.
