ISO 9239-1 ASTM E 846 Flooring Radiant Heat Flux Test Apparatus Tester Machine

The ISO 9239 Radiant Flooring Panel test is the cornerstone of the flooring materials reaction to fire tests in the Euroclass system. The apparatus measures the spread of flame of the sample under thermal exposure using a radiant heat ignition source. The thermal exposure simulates a fire growing in the room of origin that radiates through a door opening onto flooring in an adjacent room or corridor.

This flooring radiant panel test apparatus can also be used for tests to standards ASTM E648 and DIN 4102; Part 14.
