Radiant Heat Flux Test Device For Paving Materials

Radiant Heat Flux Test Device for Paving Materials

Product introduction

It is suitable for testing with paving materials that are placed in a small flame and placed horizontally and exposed to a slanted heat radiation field.

Such as: textile carpets, cork boards, wood boards, rubber sheets and plastic floor and floor coating materials. The device may reflect the burning properties of the flooring material including the substrate used, the backing material, the underlying material or other changes in the flooring material may affect the test results, which are used for testing and description under laboratory control conditions, The burning properties of the ground material against the thermal reaction of the fire.
