IEC 61935-2-23:2015

Overview

IEC 61935-2-23:2015 is an international standard published by the International Electrotechnical Commission (IEC) that provides a blank detail specification for testing Category 7 cords and work area cords in generic cabling systems. It aligns with the ISO/IEC 11801 series, which defines requirements for balanced communication cabling in structured cabling environments.

This standard offers a framework for creating detailed specifications for Category 7 cables and cords, focusing on transmission performance up to 600 MHz suitable for high-speed digital communications. It is intended for use by manufacturers, national organizations, or users who need to specify cords compliant with Category 7 requirements according to ISO/IEC 11801.

IEC 61935-2-23 complements IEC 61935-2, which details test configurations for cords, and references related standards such as IEC 61156 and IEC 60603-7, ensuring a comprehensive approach to the cable testing process.

Key Topics

• Scope and Purpose
  Specifies the layout and style for detail specifications describing balanced cords and work area cords compliant with Category 7. It sets the structure for cords with transmission characteristics up to 600 MHz, designed for the digital communications infrastructure defined by ISO/IEC 11801.

• Testing and Compliance
  Focuses on testing procedures for cords based on IEC 61935-2:2010, assuring conformity with electrical, mechanical, and environmental characteristics mandated for Category 7 cabling.

• Detail Specifications Layout
  Provides a template including essential information such as cord description, cable construction, material composition, screening, connector types, transmission parameters, and environmental performance (MICE – Mechanical, Ingress, Climatic, Electromagnetic conditions).

• Normative References
  Relies on several key standards for generic and sectional specifications for cables:

  • IEC 61156-1 and IEC 61156-6 – Generic and sectional specs for symmetrical pair cables.
  • IEC 60603-7-7 – Connectors for data transmission up to 600 MHz.
  • ISO/IEC 11801 – Generic cabling for customer premises.
  • IEC 61935-2 – Testing of balanced communication cabling.

• Guidance for Manufacturers and Users
  Offers instructions on preparing cord detail specifications using this blank template and navigating scenarios when certain parameters are “not applicable” or “not specified” while maintaining compliance with the standard requirements.

Applications

IEC 61935-2-23:2015 is highly relevant for:

• Manufacturers of Category 7 Communication Cords
  Using the blank detail template, manufacturers can draft precise specifications that ensure their cords meet international Category 7 requirements for balanced cabling systems, facilitating global interoperability and performance consistency.

• National and Regional Standardization Bodies
  This standard enables organizations to develop standardized test and product specifications tailored to their local market needs while aligned with international norms.

• System Integrators and Network Designers
  Provides clear guidelines to verify cable assemblies and cords used in work areas, ensuring network infrastructure supports high-speed data transmission and meets electromagnetic compatibility standards.

• Quality Assurance and Compliance Testing Facilities
  Helps organize testing protocols following IEC 61935-2 methods, creating reliable certification processes for cords, thereby assuring performance up to the stringent Category 7 specifications.
