Other flammability tests

You are here:

Fires can have different causes and different conditions for their spread.
The possible flammability tests are just as diverse.

The oxygen index determines the oxygen content required in a gas mixture with nitrogen to hold a sample during firing. The test is carried out in accordance with DIN EN ISO 4589-1, -2 at room temperature.

Test specimens can be ISO standard rods or textile sections 140mm x 52mm.

A cone calorimeter and a flue gas chamber are available for tests in accordance with railroad regulations.
The aim is to investigate fire development through heat radiation and to determine harmful gases and smoke gas density.

The determination of MAHRE value, max. average rate of heat emission, time of ignition, HRR - heat release rate, TSR - total smoke relesased, CO and CO2 release and mass loss is carried out in accordance with ISO 5660.

  • Sample size: 100mm x 100mm x d
  • Specification: heat input, e.g. 50 kWm²  

The smoke box in accordance with DIN EN ISO 5659-2 is used for the time-dependent determination of smoke obscuration value (VOF) and specific optical density (Ds).

  • Sample size: 75mm x 75mm x d ( ≤ 25mm) - per 3-fold determination
  • Specification: Heat input, e.g. 25 or 50 kWm² with and without pilot flame
