Key result

Test procedure:

other: Burning rate test

Remarks on result:

other: Substance does not ignite and propagate combustion either by burning with flame or smouldering along 250 mm of the solid form

No reaction with water was observed. No pyrophoric properties were seen in the study. The test substance melted when approached by the ignition flame but did not burn once the flame was removed.

Interpretation of results:

GHS criteria not met

Conclusions:

In a flammability test of PFBSK+, no ignition was observed according to EU Method A.10 or A.12, and no evidence of pyrophoric properties was observed.

Executive summary:

The flammability of PFBSK+ was evaluated according to EU Method A.10 and A.12. This test was performed following EU guidance and was GLP compliant; therefore it is considered reliable without restriction.

Description of key information

PFBSK+ is considered non-flammable.

Additional information

PFBSK+ does not contain any metals, transition metals, boron, or silicon, and the structure does not include moieties that would result in a reaction with water, air, or damp air leading to emanation of flammable gases.  The structure does not contain any chemically unstable or highly reactive groups that might lead to spontaneous ignition.  In addition, flammability testing (EU Method A.10, A.12) shows that PFBSK+ is not flammable and no evidence of pyrophoric properties was observed.

Justification for classification or non-classification

Based on the chemical structure and results of the flammability study, data is conclusive but not sufficient for classification of the substance as flammable.
