Electric radiant panel FRP

gas

The Flooring Radiant Panel is used for determining the critical radiant flux of horizontally-mounted floor covering systems, which are exposed to a flaming ignition source in a specific radiant heat environment. The test specimen is placed in a horizontal position below a gas-flued radiant panel inclined at 30° where it is exposed to a defined heat flux. A pilot flame is applied to the hotter end of the specimen. During the test, any flame front which develops is noted and a record is made of the progression of the flame front horizontally along the length of the specimen in terms of the time it takes to spread to defined distances. Also, the smoke development during the test is recorded as the light transmission in the exhaust stack. The European Construction Products Regulation requires that all European Member states use this test method as part of the requirements needed to evaluate reaction to fire performance for all flooring products, e.g. textile carpet, cork, wood, rubber, and plastics coverings as well as coatings. Results obtained by this method reflect the performance of the flooring, including any substrate if used. Modifications of the backing, bonding to a substrate, underlay or other changes of the flooring may affect test results. The following date will be reported by the Flooring Radiant Panel test: • Critical heat flux, CHF and/or HF-30, in kw/m2. • Flame spread distance, in mm. • Integral of smoke obscuration, in %xmin.
