IEC 61196-8-1:2012

Overview

IEC 61196-8-1:2012 is an international standard published by the International Electrotechnical Commission (IEC) that provides a blank detail specification framework for semi-flexible coaxial communication cables using a polytetrafluoroethylene (PTFE) dielectric. This standard forms part of the IEC 61196 series, focusing specifically on semi-flexible radio frequency (RF) and coaxial cables designed for microwave and wireless equipment applications. These cables are applicable for signal transmission within the frequency range of 500 MHz to 18 GHz.

The blank detail specification format described in IEC 61196-8-1:2012 is intended to be used alongside IEC 61196-1 and IEC 61196-8 to enable manufacturers, national organizations, or users to develop detailed specifications for specific cables, ensuring consistent documentation and compliance with international norms.
