Building Material Ignitability Test Single Flame Source
Flammability Testing Equipment
Ignitability test, also called single-flame source test.Test
apparatus corresponds to standard EN ISO 11925-2. Test results of
the building structure can be classified according to standard
The dimensions of the test specimens shall be (250 ) mm long by (90
) mm wide.
45°-tilted burner is advanced horizontally until the flame (length
20 mm) reaches the pre-set contact point with the test specimen.
Tests may need to be conducted to either surface exposure or edge
exposure, or both. The flame application time is 15 or 30 seconds
as required by sponsor.
During the test following is recorded: whether ignition occurs;
whether the flame tip reaches 150 mm above the flame application
point, and the time at which this occurs; whether ignition of the
filter paper occurs; observations of physical behavior of the test
