Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- pyrophoric solids
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is known to be stable in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- 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
- 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
- Remarks:
- CLP Implementation.
- Conclusions:
- In contact with the ignition source, the test substance swelled up and emitted some sparks. It was also observed, that the colour of the gas flame changed to orange. Under the incrustation the test substance was unchanged. The test substance could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). Therefore, no main test was performed. In conclusion, the test substance is not "highly flammable" according to the criteria of the guideline.
- Executive summary:
The determination of the flammability of the test item was performed in accordance with the EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A. 10 “Flammability (solids)”, EEC Publication No. L383, December 1992. In contact with the ignition source, the test substance swelled up and emitted some sparks. It was also observed, that the colour of the gas flame changed to orange. Under the incrustation the test substance was unchanged. The test substance could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). Therefore, no main test was performed. In conclusion, the test substance is not "highly flammable" according to the criteria of the guideline.

Description of key information
Flammability
Key study: EU method A.10. GLP study. The test substance could not be ignited with a flame and it is not classified for flammability.
Pyrophoricity
Data waiving: study scientifically not necessary / other information available.
The study does not need to be conducted because the substance is known to be satble in contact with air at room temperature for prolonged periods of time (days) and hence, the classification procedure does not need to be applied.
Substances and mixtures which, in contact with water, emmit flammable gases:
Data waiving: study scientifically not necessary / other information available.
The study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Key study: EU method A.10. GLP study.
In contact with the ignition source, the test substance swelled up and emitted some sparks. It was also observed, that the colour of the gas flame changed to orange. Under the incrustation the test substance was unchanged. The test substance could not be ignited with a flame during the preliminary test (contact time of about 2 minutes). Therefore, no main test was performed. In conclusion, the test substance is not "highly flammable" according to the criteria of the guideline.
Data waiving: There are no functional groups within the test item molecule that could cause pyrophoricity or flammability in contact with water, basis: "Guidance on information requirements and chemical safety assessment", Chapter R.7a: Endpoint specific guidance, R.7.1.10.3 and table R.7.1-27 (ECHA, May 2008).
Justification for classification or non-classification
Based on the available data, the substance is not classified for flammability in accordance to CLP Regulation (EC) 1272/2008.
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.
