Reference
The flame of the gas burner did ignite the test substance pile, which melted, burned with yellow flame and turned into a black residue. White smoke was observed. After removal of the ignition source, the flame extinguished immediately, and no propagation of combustion was observed along 200 mm length of the pile within 4 min.

Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
