IEC 61196-8:2023

Overview

IEC 61196-8:2023 - "Coaxial communication cables – Part 8: Sectional specification for semi-flexible cables with fluoropolymer dielectric" defines materials, construction, performance and test requirements for semi-flexible coaxial communication cables that use a fluoropolymer dielectric and a tin‑soaked copper wire braid outer conductor. Intended to be read in conjunction with IEC 61196-1:2005, this standard targets cables used in mobile base station antenna systems, terrestrial microwave links, radar and other wireless signal‑transmission equipment.

Key topics and technical requirements

The standard covers the following technical topics and requirements:

• Materials and cable construction
  • Inner conductor design and allowable materials
  • Fluoropolymer dielectrics (e.g., PTFE and other fluoropolymers such as PFA)
  • Outer conductor constructions (two‑layer or three‑layer options) with tin‑soaked copper braid
  • Sheath materials and protection
• Standard rating and characteristics
  • Nominal characteristic impedance
  • Rated temperature ranges and operating frequency guidance
  • Power rating and recommended bending radius
• Identification, marking and labelling
  • IEC type designation, variant identification, and required markings for traceability
• Requirements for finished cables
  • Electrical measurements (DC resistance, capacitance, characteristic impedance, return loss, etc.)
  • Environmental testing (damp heat, thermal cycling and related tests)
  • Mechanical testing (flexing, tensile and crush)
  • Fire performance and limits on toxic/harmful substances
• Quality assessment, delivery and storage
  • Conformity assessment, production quality controls, packing and storage recommendations
• Normative annexes
  • Resistance to soldering, stress‑crack resistance and pin‑hole testing procedures

Practical applications

IEC 61196-8:2023 is practically valuable for:

• Specifying and procuring semi‑flexible coaxial cables for:
  • Mobile communication base station antenna feeders
  • Terrestrial microwave and point‑to‑point links
  • Radar systems and airborne/ground wireless equipment
• Ensuring interoperability, consistent electrical performance and environmental durability of RF cable assemblies
• Guiding test labs and manufacturers in standardized electrical, mechanical and environmental testing

Who should use this standard

• RF and microwave cable manufacturers
• Telecom and wireless equipment designers and integrators
• Procurement engineers specifying coaxial cable performance
• Test laboratories and certification bodies performing compliance testing
• System architects for cellular, microwave and radar installations

Related standards

IEC 61196-8:2023 is to be read with IEC 61196-1:2005 (generic specification). It also references environmental, fire and test standards such as IEC 60068 series, IEC 60332 series, IEC 60811, IEC 60966-1, and connector standards like IEC 61169-4.
