IEC 60092-354 mandates LSZH materials—typically halogen-free compounds based on thermoplastic polyethylene (HTPE), ethylene vinyl acetate (EVA), or polyurethane (PU). These materials meet stringent EN 61034 smoke emission criteria: less than 50% optical density when tested in a closed chamber, and minimal evolution of corrosive gases (measured as hydrochloric acid equivalent per EN 50267-2-1). For additional mechanical protection, ship cables are almost always specified with armoring: a steel wire or steel tape wrapping applied over the jacket.

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.
