Product Description
Introduction:
This surface of the material spread flame tester (ISO 9239, Flooring Radiant Panel Tester) is test method that formal reflected spread of flame on flooring material back-draft condition when fire on building happened flame at compartment or room adjacent, or high temperature gas radiated to flooring surface a hot radiation heat accumulated at upper of midway during a fire at an early growing step.
More detail as see the next view; specimen is located at down horizon of 30 degree sloped gas radiation panel per horizon surface.
Pilot flame as ignition resource put a part edge of specimen on high temperature side. This equipment record ignition time by spark, moving time which flame horizontal pass by specimen of length.
