3.1
flame resistance
property of inhibiting, slowing or terminating the spread of flame
3.2

3.3
flaming
gaseous combustion process accompanied by luminescence
3.4
ignition
afterglow or flaming of the specimen under the action of the fire source

5 Ignition criteria
5.1 Ignition due to afterglow
The following phenomena are regarded as ignition due to afterglow.
a) Progressive smouldering occurs on a specimen to the extent that continuation of the test would jeopardize safety, and effective measures shall be taken for fire extinguishment.
b) During a test, the upholstered portion of the specimen basically smoulders out.
c) During a test, the specimen smoulders completely to its end, e.g., to the other side of the specimen or to/through the entire thickness of the specimen.
