Exposed Attic Floor Insulation Material Critical Radiant Flux Tester

Introduction:

• Exposed Attic Floor Insulation Material Critical Radiant Flux Tester is the cornerstone of the flooring materials reaction to fire tests in the Euroclass system.
• The test measures the spread of flame of the sample, under thermal exposure, using a radiant heat ignition source. The thermal exposure is that of a fire growing in the room of origin that through a door opening, radiates onto the floorings in an adjacent room or corridor.
• Exposed Attic Floor Insulation Material Critical Radiant Flux Tester can also be used for tests to standards ASTM E648 and DIN 4102; Part 14.

Features:

• The resulting test chamber is insulated with calcium silicate insulation board and is provided with a temperature resistant observation window.
• The stainless steel sample support assembly is mounted on a sliding platform to allow safe and easy loading of the test sample.
• The radiant heat is applied by means of a gas-fuelled panel, inclined at 30º, and directed at a horizontally mounted floor covering system specimen.
• The radiant panel generates a radiant energy flux distribution ranging from a nominal maximum of 10.9 kW/m2 to a minimum of 1.1 kW/m2.
• Dummy calibration specimen with holder, calibrated heat flux meter and mounting.
• The distance burned until flame-out is reached and converted, by calibration, into an equivalent critical radiant flux, in kW/m2.
• Heat Flux Meter: Range 0 ~ 50 kw/m2; Surface emissivity: ε=0.95± 0.05
• A smoke measuring system, according to DIN 50055, is mounted on a separate frame at the exhaust stack.
• Control Rack for convenience in use, allowing observation of the apparatus and controls during equipment set-up and calibration.
• Automatic ignition of the radiant panel and safety cut-out.
• Automatic moving T type ignition burner.
• Stainless steel hood with smoke measurement ports.
