f.
The accept-reject criteria of 4.6.2.9.3.
3.5.2 Mechanical requirements.
3.5.2.1 Interface gauging (see 4.6.3.1). Both terminals of the coaxial assembly shall be capable of passing the
gauge test procedures specified in the detail specification and satisfy accept-reject criteria of 4.6.3.1.3.
3.5.2.2 Tensile load (see 4.6.3.2). Both terminals of the coaxial assembly shall be capable of passing the tensile
load test specified in 4.6.3.2. The stress force shall be as specified in the applicable detail specification. The
assembly shall satisfy accept-reject criteria of 4.6.3.2.3.
3.5.2.3 Torque. Both terminals of the coaxial assembly shall be capable of passing the torque test specified in
4.6.3.3. The torque value shall be as specified in the applicable detail specification. The assembly shall satisfy
accept-reject criteria of 4.6.3.3.4.
3.5.2.3.1 Preparation for test. Prior to performing the torque test herein, the coupling nut shall be mated and
torqued to the value specified in the applicable detail specification.
3.5.2.4 Flexing endurance (see 4.6.3.4). The flexible and semi-flexible cable assemblies shall be capable of
passing the flexing endurance test specified in 4.6.3.4. The assembly shall satisfy accept-reject criteria of 4.6.3.4.3.
3.5.3 Environmental conditions. The complete assembly shall be so designed and constructed that no fixed part of
assembly will become loose, no moving or movable part will be shifted in position, and no performance degradation,
during operation or after storage, will be caused beyond that specified herein or in the detail specification for the
particular assembly.
3.5.3.1 Temperature. Unless otherwise specified in the detail specification, the assembly shall perform as
specified herein.
3.5.3.1.1 Operating conditions. The assembly shall perform under conditions of uncontrolled humidity, over a
temperature range of -54°C to +150°C continuously. The temperature may remain constant for a period of time or
vary at a rate as high as 1°C per second.
3.5.3.1.2 Nonoperating conditions. The assembly shall be capable of being stored at temperatures ranging from
-62°C to +150°C for long periods of time.
3.5.3.2 Altitude. Unless otherwise specified in the detail specification, the assembly shall operate continuously at
barometric pressure ranging from 30 inches Hg down to 1.32 inches Hg (approximately 70,000 feet altitude). The
altitude may remain constant for long periods or vary at a rate as high as .5 inch of mercury per second.
3.5.3.3 Temperature-altitude (see 4.6.4.1). The assembly shall provide the required performance when subjected
to the temperature-altitude tests specified in 4.6.4.1.
3.5.3.4 Vibration (see 4.6.4.2). The assembly shall be designed to withstand the vibration test specified in 4.6.4.2
without damage, deterioration, or degradation of performance. The assembly shall satisfy accept-reject criteria of
4.6.4.2.3 following vibration test.
