Overview
IEC 60966-2-8:2022 is an international standard from the International Electrotechnical Commission (IEC) that specifies the requirements for radio frequency (RF) and coaxial cable assemblies used with radio and TV receivers. This detail specification addresses cable assemblies with F-Quick connectors in accordance with IEC 61169-47 and demands quad-shield screening class A++ performance as specified in IEC 61196-6-5, supporting reliable transmission up to 3000 MHz. The standard defines the subfamily requirements, test severities, identification, and marking for these cable assemblies.
Key Topics
-
Scope and Purpose
- Applies to cable assemblies with F-Quick connectors, designed for radio and TV receiver applications.
- Covers cable types with quad-shield screening class A++ to ensure high electromagnetic compatibility (EMC) and minimal signal loss.
- Specifies requirements for assemblies’ components, performance, marking, and type variants.
-
Assemblies and Connectors
- Utilizes F-Quick connectors as per IEC 61169-47, suitable for use in 75 Ω coaxial cable networks.
- Supports both straight and right-angled, male or female connector variants for flexible installation.
-
Screening and Performance
- Requires quad-shield cables (screening class A++), providing high shielding efficiency for robust EMC.
- Addresses key cable characteristics, including nominal impedance (75 Ω) and frequency range up to 3000 MHz.
-
Marking and Identification
- Mandates clear marking on cable sheaths, including type name, screening class, IEC standard number, and manufacturer’s identification.
- Example of marking:
75-4-FM-FRF-1.5m [IEC 60966-2-8](/search?q=IEC%2060966-2-8)
-
Testing and Quality Assurance
- References subfamily requirements and test severities for both electrical and mechanical performance.
- Asserts testing for return loss, insertion loss, transfer impedance, screening attenuation, voltage proof, and mechanical endurance.
