IEC 60050-461:2008

Overview

IEC 60050-461:2008 is part of the International Electrotechnical Vocabulary (IEV) series published by the International Electrotechnical Commission (IEC). This standard provides precise terminology and definitions specifically related to electric cables, supporting the work of IEC Technical Committee 20 (TC 20), which specializes in electric cable technologies. As a consolidated second edition, IEC 60050-461 cancels and replaces the first edition from 1984 and its two amendments issued in 1993 and 1999. This document plays a critical role in harmonizing language in the electric cables industry worldwide, facilitating clear communication among designers, manufacturers, regulators, and users.

The scope of IEC 60050-461 includes terminology for all types of electric cables, components, assemblies, installation practices, testing, operation, and related accessories. It is classified as a horizontal standard per IEC Guide 108, meaning it applies broadly across various sectors without focusing on a single electrical application.

Key Topics

This standard is meticulously structured into defined sections to cover comprehensive aspects of electric cables:

• Conductors: Definitions related to cable cores and their physical and electrical characteristics.
• Insulations: Terms covering the material and technical properties of insulating layers.
• Electrical Screens and Shields: Concepts regarding cable shielding and electromagnetic compatibility.
• Cabling and Assemblies: Vocabulary for cable assembly processes and structural design.
• Coverings and Components: Terms detailing protective coverings and other cable parts.
• General Cable Types: Classification of various cable types including pressure cables, aerial insulated cables, and special cables.
• Terminations and Joints: Definitions for connectors, splices, and cable ends.
• Installation and Handling: Practices for laying, connecting, and managing cables safely.
• Testing and Operation: Terminology related to cable testing methods and operational conditions.
• Accessories: Vocabulary for cable accessories, including shield bonding and connection components.

Each section aims to provide uniform definitions reflecting the latest industry practices, enhancing interoperability and quality standards internationally.

Applications

IEC 60050-461:2008 serves diverse stakeholders involved in the design, manufacture, installation, and maintenance of electric cables, including:

• Manufacturers and Designers: To ensure consistent use of terms during product development, documentation, and quality control.
• Installation Engineers and Technicians: To standardize language and understanding in cable laying, jointing, and handling procedures.
• Testing Laboratories: For uniform terminology during electrical and mechanical testing of cables.
• Standardization Bodies and Regulators: To adopt internationally recognized vocabulary when developing related standards, certifications, and regulations.
• Academic and Training Institutions: As an authoritative reference in teaching electrotechnical vocabulary associated with cable technologies.

Overall, this vocabulary standard is essential for maintaining clarity and avoiding ambiguity across international value chains in electrical cable systems.

Related Standards

IEC 60050-461 is part of the broader IEC 60050 International Electrotechnical Vocabulary series, which covers various electrical, electronic, and related fields. It is developed in collaboration with IEC Technical Committee 20 (Electric cables) and integrates with other IEC standards for cable testing, installation, and safety, such as:

• IEC 60502 (Power cables with extruded insulation),
• IEC 60228 (Conductors of insulated cables),
• IEC 60840 (Power cables for rated voltages above 30 kV),
• IEC 62067 (Power cables with extruded insulation for rated voltages above 150 kV).

Users should consult these standards alongside IEC 60050-461 for comprehensive technical and application guidance on electric cable systems.
