IEC 60502 is an international standard published by the International Electrotechnical Commission (IEC) that sets out the specification for power cables with extruded insulation. The standard covers cables with voltage ratings from 1 kV (Um = 1.2 kV) up to 30 kV (Um = 36 kV), designed for fixed installations such as distribution networks and industrial installations. This widely recognized standard serves as a primary reference for cable manufacturers worldwide and forms the basis for numerous national and regional cable standards.

HD 620 is commonly linked to the German national standard DIN VDE 0276 Part 620 and is harmonized with international standard IEC 60502-2. The standard establishes comprehensive construction requirements, dimensional specifications, and test methods that exceed the baseline requirements of IEC 60502-2. Both HD 620 and IEC 60502-2 require compulsory conductor and insulation screening, typically applied through a triple extrusion process with the insulation layer. The test methodology for compliance is set out in HD 605 subclause 2.1.1 for insulation material and HD 605 subclause 2.1.2 for sheath material.
