Applications for the Cable Industry

NETZSCH fire testing instruments are used by cable manufacturers, testing laboratories, and certification bodies to assess the fire behavior of cable components. Key applications include:

  • Flame propagation testing:
    Evaluate how flames spread along vertically mounted cable bundles — crucial for classifying cables under the Construction Products Regulation (CPR) using EN 50399.
  • Heat release and smoke production analysis:
    Quantify heat release rate (HRR), total heat release (THR), smoke production rate (SPR), total smoke production (TSP), FIGRA, SMOGRA and smoke development to assess fire load and visibility risks during a fire.
  • Dripping particles and afterflame time:
    Identify whether burning droplets form and how long materials continue to burn after ignition (tested via UL 94 and KBT) — important for preventing secondary ignition.
  • Oxygen index determination:
    Measure the minimum oxygen concentration required to support combustion (LOI test according to ISO 4589‑2) — a key screening method for flame-retardant cable compounds.
  • Material screening and compound development:
    Support R&D by comparing flame-retardant formulations, fillers and additives for improved fire safety.
  • Certification and regulatory compliance:
    Ensure that cable products meet international fire safety requirements for installation in buildings, tunnels, industrial plants and public infrastructure.

Cables and lines - Invisible lifelines of our modern world

They power our homes, connect our devices and keep critical infrastructure running — all while working quietly and reliably in the background.

To ensure the highest level of safety and fire protection, it is crucial to understand how cable materials behave in a fire. Only through precise testing and reliable data can manufacturers design cables that perform well and protect lives, property and the systems we depend on daily.
