Key value for chemical safety assessment

Flammability:
non flammable

Additional information

The determination of the flammability of the test item was performed in a valid GLP study in accordance with EU method A.10. In contact with the ignition source (2 minutes), FAT 40850/A TE glowed and carbonized. The propagation time of the glow for 100 mm was significantly above the limit given by the guideline and underneath the carbonized surface, about 3 mm unchanged test item remained. Therefore, no main test was performed and FAT 40850/A TE is not "highly flammable" according to the criteria of the guideline. The appraisal of the molecular structure indicates no risk with respect to pyrophoric properties or the potential of evolving flammable gases in contact with water or humid air. Studies were performed in aqueous test systems (e.g. water solubility). The test item did not show any spontaneous ignition or formation of flammable gases performing the above mentioned study. In conclusion it it assessed that FAT 40850/A TE does not ignite spontaneously when in contact with water or humid air and shows no risk with respect to pyrophoric properties.

Justification for classification or non-classification

The substance FAT 40850/A TE could not be ignited in a standard flammability test for solid substances. In addition, the substance neither does spontaneously ignite in contact with water or humid air nor does it release ignitable gases. The substance FAT 40850/A TE hence does not require classification for flammability.
