DX8335A Radiation Plate Flame Spread Tester

Product Introduction:

Radiant panel flame spread tester is used to test the flammability of building surface materials (ASTM E162) and foam plastics (ASTM D3675) by using gas thermal radiant panel. The flame spread index (IS) is determined by factors such as flame spread and heat dissipation. It is a necessary parameter in many industry standards, especially for public transportation (trains and buses). Data collection and analysis are automatically completed by software.

Reference standard:

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