IEC 61935-2-24:2015

Overview

IEC 61935-2-24:2015 is an international standard developed by the International Electrotechnical Commission (IEC), focusing on the testing of balanced communication cabling. This document serves as a blank detail specification for cords and work area cords compliant with Category 7A, as defined in the ISO/IEC 11801 series. It establishes a standardized layout and format for preparing detail specifications relating to cords with transmission characteristics up to 1,000 MHz, essential for modern digital communication systems.

The standard is intended to be used conjointly with IEC 61935-2, IEC 61156-1, IEC 61156-6, and IEC 60603-7-71, ensuring comprehensive guidance for cable construction, testing procedures, and compliance verification.

Key Topics

• Category 7A Cord Specifications: Defines the requirements and characteristics for cords and work area cords categorized under 7A, providing higher performance capabilities up to 1,000 MHz bandwidth.
• Blank Detail Specification Framework: Offers a template format for manufacturers, national organizations, and users to prepare their specific detail specifications while ensuring consistency and compliance.
• Testing Methodology: Details the test configuration applicable to Category 7A cords, primarily referencing IEC 61935-2.
• Transmission Characteristics: Emphasizes maintaining transmission attributes like characteristic impedance, signal attenuation, and coupling attenuation in line with ISO/IEC 11801.
• Environmental and Mechanical Requirements: Aligns with the MICE (Mechanical, Ingress, Climatic, Electromagnetic) table from ISO/IEC 24702 to specify environmental severities and ensure cable durability in varied conditions.
• Normative References: Incorporates relevant standards such as IEC 60603-7-71 (connectors), IEC 61156 series (symmetrical cables), and ISO/IEC 11801 (generic cabling systems), providing a robust regulatory framework.

Applications

• Telecommunications Infrastructure: Used by telecommunications providers to specify and verify Category 7A cabling components in data centers, office environments, and structured cabling systems.
• Work Area Connectivity: Ensures precise standards for cables connecting equipment in the work area, such as patch cords and work area cords, supporting high-speed digital communication.
• Manufacturing and Quality Control: Manufacturers employ this blank detail specification to develop product data sheets and testing protocols that meet international performance and compatibility standards.
• National and International Standardization: Facilitates uniformity across regions by allowing national committees or organizations to generate compliant specifications based on the IEC 61935-2-24 template.
• Digital Communication Systems: Optimizes performance for applications requiring high-frequency data transmission, including Gigabit Ethernet, multimedia transmission, and industrial communication systems.

Related Standards

• ISO/IEC 11801: The overarching generic cabling standard defining the categories and performance of structured cabling systems, including Category 7A.
• IEC 61935-2: Provides detailed test methods for balanced and coaxial communication cabling compliant with ISO/IEC 11801.
• IEC 61156 Series: Offers comprehensive specifications for symmetrical pair and quad cables used in digital communications, outlining construction and electrical characteristics.
• IEC 60603-7-71: Specifies requirements for shielded connectors compatible with Category 7A cables up to 1,000 MHz.
• ISO/IEC 24702: Addresses generic cabling for industrial premises, supporting harsh environment applications considering MICE conditions.
