Overview
IEC 61196-4-1:2016 is an international standard published by the International Electrotechnical Commission (IEC) that defines a blank detail specification for radiating coaxial communication cables. These radiating cables serve a critical role in wireless communication systems where traditional radio transmissions may be impractical or impossible, such as in tunnels, railways, subways, highways, elevators, and similar complex environments.
This part of the IEC 61196 series specifies the standardized format and layout for creating detailed cable specifications, enabling manufacturers, national organizations, and users to develop custom detail specifications tailored to specific applications. It complements the core documents IEC 61196-1:2005 (generic specification for coaxial cables) and IEC 61196-4:2015 (sectional specification for radiating cables).

Key Topics
-
Scope and Purpose
Defines the use of radiating coaxial cables intended for environments requiring enhanced radio coverage where conventional systems fail. Establishes a blank template to detail specific cable parameters.
-
Detail Specification Layout
The standard sets out a comprehensive framework for documenting key cable attributes, including:
- Cable description and construction details
- Electrical parameters such as characteristic impedance, attenuation, capacitance, and frequency rating
- Mechanical and environmental characteristics including bending radius, temperature range, and ageing
- Fire performance requirements as mandated by regional or national regulations
-
Guidance for Specification Development
Provides instructions on filling out the blank specification with required information. Not applicable parameters are marked as “na,” while unspecified values are indicated as “ns.” This provides flexibility while maintaining uniformity.
-
Cross-Referencing Standards
The blank detail specification is intended to be used together with:
Applications
IEC 61196-4-1:2016 applies primarily to wireless communication infrastructure projects that require radiating coaxial cables to ensure reliable signal distribution in challenging environments. Its practical uses include:
- Transport tunnels and subways where direct radio signals are obstructed by walls and earth
- Railway and highway communication systems enabling continuous data transmission along tracks and roads
- Elevator shafts and underground facilities where conventional transmission is unreliable
- Large buildings and industrial complexes for enhanced in-building wireless coverage
- Emergency and safety communication systems requiring guaranteed signal robustness
By adhering to this standard when specifying radiating cables, installers and manufacturers can ensure interoperability, optimal performance, and compliance with safety and environmental criteria.
