Iso 9239 astm e648 and nfpa 253 are standard methods of test for determining the critical radiant flux of floor covering materials under controlled combustion conditions.
Floor radiant panel test.
Astm e648 this test method is used to measure the critical radiant flux of horizontally mounted floor covering systems exposed to a flaming ignition source in a graded radiant heat environment within a test chamber.
During radiant panel tests we simulate a likely set of conditions which may lead to fire spread in a floor covering system.
October 7 2018 by lisa league this test measures a carpet s ability to spread flame in a corridor or exit way when a fully developed fire is nearby.
1 1 this fire test response standard covers a procedure for measuring the critical radiant flux of horizontally mounted floor covering systems exposed to a flaming ignition source in a graded radiant heat energy environment in a test chamber.
What is astm e 648 standard test method for critical radiant flux of floor covering systems using a radiant heat energy source flooring radiant panel test.
A specimen is mounted over underlayment a simulated concrete structural floor bonded to a simulated structural floor or otherwise mounted in a typical and representative way.
In this test a horizontally mounted floor covering system is exposed to radiant energy from a gas air fuel radiant panel mounted above one end of the sample and inclined at a 30 degree angle.
This test also measures the distance of any flame spread that occurs.
The radiant panel generates a heat profile along the length of the sample.
