Appendix 3 – Interpretation of ResultsEvaluating unusual test specimen behaviour (see paragraph 2.2 of this part)

  Unusual behaviour Guidance on classification
1 Flashing, no steady flame Report furthest progress of flame and time, and whether or not flash is on centreline. Classify on basis of the data.
2 Explosive spalling, no flashing or flame Accept material as passing test.
3 Rapid flash over surface, later steady flame progress Report result for both flame fronts but classify on basis of worst performance for each of the four test parameters in the two burning regimes.
4 Specimen or veneer melts and drips off, no flame Report behaviour and extent of advance on specimen.
5 Explosive spalling, and flame on exposed part of specimen Report explosions and classify on basis of flame progress irrespective of whether above or below centreline
6 Specimen or veneer melts, burns, and drips off Reject material regardless of criteria. For floor covering, no more than 10 burning drops are acceptable.
7 Pilot flame extinguished Report occurrence, reject data and repeat test.
8 Specimen breaks up, and falls out of holder Report behaviour, but classify on basis of worst performance with and without specimen restraint in paragraph 8.3.2 of appendix 1 to this part.
9 Substantial jetting combustible pyrolysis gases from specimen, adhesive or bonding agents Report that it is not classified as low flame-spread.
10 Small flame remaining along the edge of specimen Report behaviour and terminate the test 3 min after flaming on exposed surface of specimen ceased.
