Abstract IEC E applies to radiating coaxial communication cables. These cables are intended for use in wireless communication systems, such as tunnels, railways, highways, subways, elevators and other installations in which conventional antenna transmission is not satisfactory or even impossible. This third edition cancels and replaces the second edition published in This edition constitutes a technical revision. The main changes with respect to the previous edition are as follows: - a definition for coupling loss was added, - Clause 4 "Materials and cable construction" was added, - rated temperature range, operating frequency and radiating characteristics as standard rating and characteristics were added, - identification, marking and labeling was added, - the tables of test procedures were revised, - quality assessment and packaging was added, - Annex C, "Coupling loss around circumferential orientation of radiating cable" was added, - Annex D "Radiating intensity around circumferential orientation of radiating cable" was added.
