Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 20 June 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- other: The test material ignited, but the combustion propagated slowly, for longer than 4 minutes, therefore no main test was performed.
- Interpretation of results:
- other: Not classified in accordance with EU Criteria.
- Conclusions:
- Under the conditions of this study the test material ignited, but the combustion propagated slowly, for longer than 4 minutes, therefore the test material is considered not to be highly flammable.
- Executive summary:
The flammability of the test material was investigated in accordance with the standardised guideline EU Method A.10, under GLP conditions.
In the preliminary test the test material began to glow due to influence of flame, then sometimes flamed up, but the combustion propagated mainly with smouldering along the powder train. After the ignition green lightweight, fluffy ash formed. The time of combustion and glow of a 200 mm length of the powder train was about 15 min. Based on the results of the preliminary test, no main test was performed.
Under the conditions of this study the test material ignited, but the combustion propagated slowly, for longer than 4 minutes, therefore the test material is considered not to be highly flammable.

Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
The flammability of the test material was investigated in accordance with the standardised guideline EU Method A.10, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
In the preliminary test the test material began to glow due to influence of flame, then sometimes flamed up, but the combustion propagated mainly with smouldering along the powder train. After the ignition green lightweight, fluffy ash formed. The time of combustion and glow of a 200 mm length of the powder train was about 15 min. Based on the results of the preliminary test, no main test was performed.
Under the conditions of this study the test material ignited, but the combustion propagated slowly, for longer than 4 minutes, therefore the test material is considered not to be highly flammable.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to flammability.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
