Applicant's summary and conclusion
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- The substance has not to be classified as flammable solid according to UN-transportation classification and EU-GHS/CLP
- Executive summary:
The substance was tested for flammability according to VDI 2263 sheet 1. When using a flame as an ignition source only melting of the substnace was observed at room temperature. When using a hot platinum wire the substance ignited but after removal of the ignition source no further burning was noticed. The burning behaviour of the substance could be characterized with burning number 3 (local burning with only weak propargation of the flame at the maximum).
The determination of the burning rate was not required since there was no propargation of the flame.
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.
