Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 16 November 2007 - 23 February 2008
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- 34 min
- 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
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flame of a gas burner could ignite the test substance pile. The test substance burned with a yellow flame, developed smoke and turned into a grey/black ash residue. After removal of the ignition source, propagation of combustion by smouldering was observed. The burning time over a distance of 200 mm was 34 minutes and 19 seconds.
Because no burning with flame or smouldering over 200 mm within 4 minutes was observed, R507-2 is considered not highly flammable. - Executive summary:
The flame of a gas burner could ignite the test substance pile. The test substance burned with a yellow flame, developed smoke and turned into a grey/black ash residue. After removal of the ignition source, propagation of combustion by smouldering was observed. The burning time over a distance of 200 mm was 34 minutes and 19 seconds.
Because no burning with flame or smouldering over 200 mm within 4 minutes was observed, R507-2 is considered not highly flammable.

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.
