儀器簡介：

The Radiant Panel Flame Spread Tester is an equipment using gas ignited Radiant heat panel to test the surface combustibility of Building product (ASTM E 162) and cellular plastics (ASTM E 365)， Radiant Panel Index(Is) is measured by the flame radio waves,， Critical Heat Flux,，(CHF) and Heat Release Rate(kW/m2).

技術參數(shù)：

• ASTM E 162: Standard Test Method for surface Flammability of materials Using a

Radiant Heat Energy Source

• ASTM D 3675: Standard Test Method for surface Flammability of Materials using

A Radiant Heat Energy Source

主要特點：

• Reflection panel is composed of a cast iron frame with vertically applied

porosity fire resistant material with a 305X457mm size exposed reflection surface

and is designed to function at 815 ℃.

• The Calibration burner should have 1.8mm holes in 16mm intervals,， and should

be manufactured along the middle line.

• An exhaustion device with a 0.5 m/s airflow exhaustion rate is installed.

• In order to control the surface heat of the reflection panel,， a 180℃ ~ 230℃

(Black body temperature) range will be given， and a ±5℃ accuracy,， fit to observe

a surface of 250mm radius at 2 m distance.
