This specification covers flexible and semirigid cables with solid and semisolid
dielectric cores, with single, dual and twin inner conductors. Cables covered by this specification are
primarily intended for use as transmission lines to conduct energy in a simple power transfer
continuously or intermittently. In general, these cables are designed for low-loss, stable operation
from the relatively low frequencies through the higher frequencies in the microwave and radar
regions of the frequency spectrum. Cables may also be used as circuit elements, delay lines or
impedance matching devices. These cables are supplied under a reliability assurance program as
specified in section 3.
