MIL-DTL-28830E
3.5 Performance.
3.5.1 Continuity. When tested as specified in 4.7.2, each conductor in each reel of cable shall be
electrically continuous between ends.
3.5.2 Dielectric withstanding voltage. When tested as specified in 4.7.3, the completed cable shall
withstand the voltage specified (see 3.1) without breakdown.
3.5.3 Spark test (jacketed cable only). When tested as specified in 4.7.4, jacketed cable shall have
a continuous jacket without cracks, breaks, or holes. A puncture of the jacket by the applied voltage
shall constitute a point of failure (see 3.1).
3.5.4 Insulation resistance. When tested as specified in 4.7.5, the insulation resistance shall be
not less than 100,000 megohms per 1,000 feet (305 meters).
3.5.5 Leak test (type 1). When tested as specified in 4.7.6, the cable shall not increase in
capacitance by more than 5 percent of the initial capacitance.
3.5.6 Attenuation. When tested as specified in 4.7.7, the attenuation in decibels (dB) per 100 feet
(30 meters) shall not exceed the maximum values specified (see 3.1).
3.5.7 Velocity of propagation. When tested as specified in 4.7.8, the velocity of propagation shall be
as specified (see 3.1).
3.5.8 Capacitance. When tested as specified in 4.7.9, the cable capacitance shall be as specified
(see 3.1).
3.5.9 Impedance. When tested as specified in 4.7.10, the impedance of the cable shall be as
specified (see 3.1).
3.5.10 VSWR. When tested as specified in 4.7.11, the cable shall have a maximum VSWR as
specified, with respect to a 50 ± 2 ohm termination, over the frequency range specified (see 3.1).
3.5.11 Cold bend (jacketed cable only). When tested as specified in 4.7.12, the cable jackets shall
show no evidence of cracking or splitting.
3.5.12 Flexibility. When tested as specified in 4.7.13, the finished cable shall not exhibit kinking,
3.5.13 Temperature cycling. When tested as specified in 4.7.14, the cable shall exhibit no evidence
of mechanical damage.
3.5.14 Thermal shock. When tested as specified in 4.7.15, there shall be no physical damage to
any dielectric material and the change in dimensions from the original shall be .062 inch (1.57 mm)
maximum for the center conductor and .125 inch (3.18 mm) maximum for the dielectric material.
3.5.15 Flame propagation (type IV jacketed cable only) (see 3.1). When tested as specified in
4.7.17, samples of completed cable shall be self-extinguishing and shall not burn to the top of the
tray.
