IEC 61196-1-318:2008

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).
