The specimen is mounted in a water-cooled holder and is exposed to a radiant panel over a ten minute test duration. In addition, a pilot flame is applied to the bottom corner of the specimen during the first minute of test. The time required for the flame front to reach reference marks on the specimen is noted, together with the extent of flame spread at one minute thirty seconds test duration and at the end of the test.
