IEC 60228 is an international standard for the construction and testing of insulated cables and wires. The standard specifies the requirements for the design, construction, and testing of electric cables and wires with extruded insulation.

These classes, defined in the original 1978 edition, remain the backbone of the standard. The table below provides a practical reference for the key parameters of Class 2 stranded copper conductors, illustrating the relationship between nominal cross-sectional area, wire stranding, and maximum resistance.
