Results and discussion
Flammable solids
- Key result
- Test procedure:
- burning rate test over 100 mm length
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
Applicant's summary and conclusion
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The substance is not classified as a flammable solid.
- Executive summary:
The flammability of the substance was studied under GLP to UN Test N.1. The substance was formed into an unbroken train of material, approximately 250 mm long, on a non-combustible, impervious, low heat-conducting plate. A preliminary test was conducted to determine whether or not the sample ignites and propagates combustion over 200 mm within 2 minutes, either by burning with a flame or by smouldering. The test substances melted and ignited on application of the ignition source, but self-extinguished rapidly on its removal. It did not propagate combustion and the burning time over 200 mm could not be determined.
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).
