Overview
IEC 60245-4:1994/AMD1:1997 is an important international amendment issued by the International Electrotechnical Commission (IEC) focused on rubber insulated cables with rated voltages up to and including 450/750 V. This amendment, Part 4 of the series, specifically addresses cords and flexible cables, providing updated and precise specifications for dimensions, insulation, and sheath thicknesses of these cable types.
The amendment updates several tables with new dimensional requirements for Type 245 cables (based on IEC 51, 53, 57, 58, and 66), ensuring enhanced uniformity, safety, and performance in flexible rubber insulated cables used widely in electrical installations.
Key Topics
Scope and Purpose
The amendment refines the dimensional characteristics of rubber insulated flexible cords and cables, focusing on rated voltages up to 450/750 V. It defines precise values for:- Number and nominal cross-sectional area of conductors
- Thickness of insulation and sheath layers
- Mean overall diameter (including lower and upper limits)
Updated Dimensional Tables
Several key tables are revised in this amendment to specify:- Thickness specifications for insulation and sheaths
- Minimum and maximum diameters for cables with varying conductor counts and cross-sectional areas
- Layer structure of sheaths including single and double-layer configurations
Cable Types Covered
The tables provide detailed dimensional data for Type 245 flexible cables per IEC 51, 53, 57, 58, and 66 standards, covering:- Single conductor cables
- Multi-conductor configurations (e.g., 2-core, 3-core)
- Varied cross-sectional conductor sizes from 0.75 mm² up to 400 mm²
Technical Committee and Document Origin
Prepared by IEC Technical Committee 20, Subcommittee 20B, which specializes in low-voltage electric cables. This amendment was based on consensus voting and technical reviews (Documents 20B/230/FDIS and 20B/245/RVD).
Applications
Electrical Wiring and Power Distribution
Ensures cables used for flexible power connections comply with internationally recognized dimensions, crucial for electrical safety and performance.Flexible Cable Manufacturing
Manufacturers can use this standard to design and produce rubber insulated flexible cords and cables that meet strict IEC requirements. This supports consistent quality and compatibility in the global market.Product Testing and Quality Assurance
The amendment defines parameters that facilitate standardized inspection, mechanical testing, and certification processes during quality control of flexible cables.Industrial, Commercial, and Domestic Environments
Flexibility and durability of rubber insulated cables specified here suit applications ranging from household appliances to industrial machinery, where cables may undergo bending and mechanical stress.
