Overview
IEC 60966-4:2003 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies requirements for semi-rigid coaxial cable assemblies operating in the transverse electromagnetic mode (TEM). This sectional specification is part 4 of the IEC 60966 series which covers radio frequency and coaxial cable assemblies. It establishes uniform protocols for testing the electrical, mechanical, and environmental properties of semi-rigid coaxial cable assemblies, consisting of semi-rigid coaxial cables and coaxial connectors.
The standard targets manufacturers, designers, and quality assurance professionals involved in the production and use of semi-rigid coaxial cable assemblies in radio frequency applications. It aims to ensure interoperability, reliable performance, and consistent quality across global markets.
