ASTM E162 Radiant Panel Flame Spread Apparatus
Product Introduction
The radiation propagation tester is used to measure the fire propagation performance of materials. The sample is exposed to a specific flame radiation source at 30 degrees, and the flame spread index Is is calculated by measuring the temperature rise of the chimney and the distance of the flame spreading downward.
