This part of IEC 61196 applies to coaxial communication cables. It specifies several test methods for determining: • heat flow resistance of dielectric: the resistance of the dielectric to the mechanical distortion induced by radial stress imposed by the inner conductor at high temperatures; • resistance to heat exposure (formerly “heat shock resistance“): the resistance of the dielectric or the sheath to high temperatures; • heat behaviour of semi-rigid cables: the ability of the cable construction of semi-rigid cables to withstand the expansion of the dielectric at high temperature; • dimensional stability: the displacement of the cable elements with respect to each other in order to demonstrate the suitability of a cable for use with connectors.
