The standard specifies nominal cross-sectional areas ranging from 0.5 mm² to 3,500 mm²
IEC 60228 is an international technical standard published by the International Electrotechnical Commission (IEC) and managed by Technical Committee 20 (Electric Cables). The document defines the standard nominal cross-sectional areas for conductors, ranging from 0.5 mm² to 3,500 mm². It provides critical requirements for the number and size of individual wires, resistance values, and specifications for various conductor types, including solid, stranded, and Milliken for copper, aluminum, and aluminum alloys in fixed installations, as well as flexible copper conductors. It is important to note that the standard does not apply to conductors for telecommunication purposes.
In the electrical engineering and cable manufacturing industries, standardization ensures safety, compatibility, and reliability. One of the most critical international benchmarks is , established by the International Electrotechnical Commission (IEC).
