EN 50399 Standard Wire Cable Heat Release Tester Fire Growth Rate Testing Machine Smoke Production Rate Analyzer Heat Release Tester

This testing system is designed for medium-scale fire tests simulating bundled cables or optical fibers. During testing, cables are mounted on a vertical standard steel ladder and ignited using a specified ignition source to evaluate combustion behavior and fire performance.

The test provides critical data on cable fire characteristics during initial combustion stages. Heat release rate measurements assess flame propagation risk along cables and potential fire impact on adjacent areas, while smoke density tests evaluate visibility in fire zones and smoke hazards to human safety.
