Radiant Plate Flame Spread Tester Test The Flammability Of Building Surface Materials

DX8335A Radiant Plate Flame Spread Tester

Product Introduction:

The Radiant Panel Flame Spread Tester uses gas-fired radiant panels to test the flammability of building surface materials (ASTM E162) and foams (ASTM D3675). The Flame Spread Index (IS), which is determined by factors such as flame spread and heat dissipation. It is used as a mandatory parameter in many industry norms, especially for public transport (trains and buses). Data acquisition and analysis are done automatically by the software.

Reference Standards:

ASTM E 162 Standard Test Method for Testing Surface Flammability of Materials Using Radiant Thermal Energy • ASTM D 3675: Standard Test Method for Testing Surface Flammability of Flexible Porous Materials Using Radiant Thermal Energy Sources
