Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- 2013-01-10
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Determination has been run according to standardized method but without GLP compliance.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- yes
- Remarks:
- The substance strip was only 150 mm long instead of 250 mm, because no more sample was available for this screening test. But this deviation had no influence on the final test result.
- GLP compliance:
- no
- Test procedure:
- burning rate test: preliminary screening test
- 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:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- The substance is not considered as highly flammable.
- Executive summary:
The test substance locally ignited, but no (sufficient) propagation of combustion occurred. This means that it is not considered as highly flammable according to EC Guideline A.10.

Description of key information
A close analogue is not considered as highly flammable.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
The test substance locally ignited, but no (sufficient) propagation of combustion occurred. This means that it is not considered as highly flammable according to EC Guideline A.10.
Justification for classification or non-classification
In the screening test the gas flame was applied to one end of the substance train. Only melting and ignition took place of that part of the substance that was exposed to the gas flame. No propagation of combustion occurred and the flame extinguishes as soon as the gas flame is removed. This means that the substance is not considered as highly flammable and that no further testing is required.
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).
