IEC 60966-2-5:2009

Overview

IEC 60966-2-5:2009 is an international standard issued by the International Electrotechnical Commission (IEC) that specifies detailed requirements for radio frequency (RF) and coaxial cable assemblies used in radio and TV receivers. The standard addresses cable assemblies with a frequency range from 0 MHz to 1,000 MHz and applies specifically to flexible coaxial cables described by IEC 60096-2. It focuses on the cable assemblies subfamily 9,52, which incorporate connectors compliant with IEC 61169-2.

This third edition, published in 2009, revises the previous edition by updating references and introducing requirements related to screening attenuation for improved electromagnetic compatibility (EMC).

Key Topics

• Scope and Application
  Defines technical criteria for RF and coaxial cable assemblies used in consumer radio and television receivers, ensuring compatibility and performance across a frequency range from DC to 1 GHz.

• Connector Specification
  Specifies cable assemblies utilizing IEC 61169-2 type connectors, which include straight and right-angle plugs and sockets suited for 75 Ω characteristic impedance systems.

• Performance Parameters

  • Reflection Properties:
    Minimum reflection loss values are defined, e.g., greater than 23 dB from 5 MHz to 400 MHz, ensuring minimal signal reflections that degrade signal quality.
  • Insertion Loss:
    Defined at less than 0.08 dB + 0.4 dB per meter up to 1,000 MHz, supporting efficient signal transmission.
  • Screening Effectiveness:
    Includes transfer impedance limits (e.g., <5 mΩ/m for Class A at 5-30 MHz) and screening attenuation requirements (>85 dB for Class A from 30 MHz to 1,000 MHz) to minimize external electromagnetic interference.
  • Voltage and Insulation:
    Voltage proof up to 1.0 kV (50-65 Hz), insulation resistance above 10 MΩ, ensuring safety and reliability.

• Mechanical Requirements
  Specifies tensile strength (>45 N), flexure endurance (500 cycles at 5 N), flexing endurance, and crushing resistance (>700 N), guaranteeing durability in typical installation and operational conditions.

• Testing and Quality Assurance
  Defined test groups cover visual inspection, dimensional inspection, electrical characteristics, and mechanical strength. Tests may be conducted lot-by-lot or at specified intervals under qualification and capability approval procedures.

• Referenced Standards
  To ensure completeness, this detail specification is intended to be used in conjunction with:

  • IEC 60966-1 (generic specification for RF and coaxial cable assemblies)
  • IEC 60966-2-1 & IEC 60966-2-2 (sectional and blank detail specifications)
  • IEC 61169-2 (radio frequency coaxial connectors type 9.52)
  • IEC 62153-4-3 (EMC test methods for metallic communication cables)

Applications

IEC 60966-2-5 primarily targets manufacturers, testers, and quality controllers of RF cable assemblies used in the broadcast and consumer electronics industries. Specific applications include:

• Radio and TV Receivers:
  Ensures reliable signal transmission systems for household and commercial radio and television reception equipment, aligning with performance and durability expectations.

• Cable Assembly Manufacturing:
  Guides design, production, and testing processes for compliant coaxial assemblies, supporting standardization and interoperability.

• Electromagnetic Compatibility (EMC):
  Assists in meeting EMC requirements by specifying screening attenuation and transfer impedance parameters, reducing signal interference and improving receiver performance.

• Installation and Field Use:
  Provides guidelines for mechanical robustness to withstand bending, flexing, and crushing stresses encountered during installation and everyday use.
