Overview
IEC 60245-4:1994/AMD2:2003 is the Amendment 2 to the international standard for rubber insulated cables rated up to and including 450/750 V. This amendment revises Part 4, which specifically covers cords and flexible cables used in various electrical applications. Developed by the International Electrotechnical Commission (IEC) Technical Committee 20, this amendment updates several technical requirements and testing methods ensuring enhanced product quality, safety, and performance consistency in rubber insulated flexible cables.
The amendment includes modifications to insulation application techniques, separator specifications, and testing procedures. It introduces references to related standards targeting cables with high flexibility, signifying the growing importance of flexible cords in industrial and consumer use.
Key Topics
Scope and Application: Defines requirements for cords and flexible rubber insulated cables with rated voltages up to 450/750 V, used in electric power systems and equipment.
Insulation Updates: Specifies that insulation must be applied by extrusion and updates the insulation quality classification from "IE 1" to the higher standard "IE 4" for better durability and electrical insulation.
Separator Requirements: Removal of certain restrictive clauses on separators enhances design flexibility while maintaining compliance with referenced standards.
New Material Additions: Introduction of an optional proofed textile tape applied helically on cores with conductors above 4 mm² to enhance mechanical protection without damaging insulation.
Testing Enhancements:
- Introduction of tests for tensile strength after ageing using updated methods (IEC T 60811-1-2 clause 8.2).
- Addition of ozone resistance testing (IEC T 60811-2-1 clause 8) to ensure cable longevity and performance in outdoor or harsh environments.
- Clarification that dimensions conform to IEC 60719 calculations, ensuring dimensional accuracy.
Normative References: Adds IEC 60245-8:1998 to address cords designed for applications requiring high flexibility, facilitating cross-standard consistency.
Practical Applications
IEC 60245-4:1994/AMD2:2003 applies directly to manufacturers, designers, and quality assurance professionals involved in the production and certification of rubber insulated cords and flexible cables:
- Electrical equipment suppliers requiring flexible rubber cables for rated voltages up to 450/750 V.
- Industrial sectors where durable, flexible power cords are essential, including machinery, control devices, and mobile equipment.
- Consumer appliance manufacturers ensuring compliance with international safety and performance standards.
- Testing laboratories implementing the updated tensile and ozone resistance procedures to validate cable reliability over service life.
- Product designers integrating optional features like proofed textile tape for enhanced mechanical protection on larger conductor cables.
This amendment supports the sustained safety, durability, and flexibility necessary for modern electrical cable applications, responding to evolving industry demands.
