3.2.3.2 Operating temperature. Each assembly shall meet the performance
requirements of 3.2.1 during and after exposure to temperatures within the
range of -45 and +52 Celsius (C).
3.2.3.3 Storage temperature. Each assembly shall meet the performance
requirements of 3.2.1 after exposure to ambient air temperature within the
range of -50 and +71C.
3.3 Design and construction.
3.3.1 Production drawings. Each assembly shall be fabricated and assembled
in accordance with the applicable assembly drawing. The typical installation
details of figures 1 through 12 and the requirements of this specification
shall guide fabrication where it is not detailed by the assembly drawing.
3.3.2 Standards of manufacture.
3.3.2.1 Dimensional and angular tolerances. Unless otherwise specified on
the cable assembly drawing, tolerances on length dimensions shall be as
follows:
Tolerance (inches)
Length (inches)
0 to 11.99
-0, +1.00
12.00 to 71.99
-0, +2.00
72.00 and up
-0, +3.00
Unless otherwise specified, tolerances on connector clocking to connector
backshell or boot angles shall be 15.
3.3.2.2 Solder requirements.
Solder requirements shall be as specified on
the cable assembly drawing.
3.3.2.3 Crimping requirements. Crimp type connector contacts shall be
crimped using crimping procedures defined in MIL-C-22520.
3.3.2.4 Shielded wire terminations. Heat shrinkable solder sleeves shall
be used to connect wire shields to the pigtail wires for termination. These
terminations shall be wired in accordance with the wiring diagram. The
sleeves shall be applied using an Infrared heat gun and shall meet the
requirements of NAS 1747. Unterminated shield ends shall be covered with the
heat shrinkable tubing shown on drawings and shall extend a minimum of 1/4
inch on each side of the shield end. Sleeves shall be placed not further than
3 inches from the rear of the connector grommet on connectors with straight
backshells and 4 inches from the rear of the connector grommet on connectors
with 45 or 90 backshells. The sleeves shall be staggered so that the wire
bundle remains at a minimum. Each shield shall be trimmed and sealed to
eliminate any frayed ends prior to installing sleeves on tubing.
