Flooring Radiant Panel Tester, ISO9239-1 ASTM E648 ASTM E970 Critical Radiant Flux Test Machine

The Flooring Radiant Panel Tester is used to measure the critical radiant flux of floor coverings. Critical radiant flux refers to the incident heat per unit area. A higher incident heat value means the material requires more heat to ignite, indicating better stability and lower risk of ignition.

This test apparatus is equipped with a thermal radiation source and a T-shaped burner. As the test specimen is placed farther away from the radiation source, the thermal radiant flux received on its surface decreases. The specimen is ignited by the T-shaped burner. After the flame extinguishes, the damage distance of the specimen is measured, and the corresponding thermal radiant flux value is the critical radiant flux.
