- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 07 March 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test N.1 (Test method for readily combustible solids)
- Version / remarks:
- 2015
- Deviations:
- no
- 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:
- 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:
- other: Not classified in accordance with EU Criteria
- Conclusions:
- Under the conditions of this study, the test material should be considered as not highly flammable.
- Executive summary:
The flammability of the test material was investigated in accordance with the standardised guidelines UN Method N1 and EU Method A.10, under GLP conditions.
A safety test was performed where a small amount of the test material was heated on a magnesia groove with a gas burner in order to derive safety precautions. Melting to a yellow liquid was observed; the liquid evaporated without any residue. In the preliminary screening test the test material was heated with the flame of a gas burner for two minutes in the preliminary screening test. Melting to a yellow liquid was observed during heating. No ignition occurred within two minutes. Since ignition did not occur within two minutes, no determination of burning rate was necessary.
Under the conditions of this study, the test material should be considered as not highly flammable.
Reference
Safety Pre-Test
- Melting to a yellow liquid was observed, the liquid evaporated without any residue.
Preliminary Screening Test
- In the preliminary screening test following the EU and the UN method, the test material was heated with the flame of a Teclu burner. Melting to a yellow liquid was observed during heating. No ignition occurred within two minutes.
- No ignition was observed throughout the course of the test.
- The test material should be considered as not highly flammable (for EU regulations) and as a non-flammable solid (for UN regulations).
- No observations were made which might cause doubts concerning the validity of the study outcome.

Additional information
Solids (Krebs, 2018)
The flammability of the test material was investigated in accordance with the standardised guidelines UN Method N1 and 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).
A safety test was performed where a small amount of the test material was heated on a magnesia groove with a gas burner in order to derive safety precautions. Melting to a yellow liquid was observed; the liquid evaporated without any residue. In the preliminary screening test the test material was heated with the flame of a gas burner for two minutes in the preliminary screening test. Melting to a yellow liquid was observed during heating. No ignition occurred within two minutes. Since ignition did not occur within two minutes, no determination of burning rate was necessary.
Under the conditions of this study, the test material should be considered as not highly flammable
In accordance with Section 1 of Annex XI of Regulation (EC) No. 1907/2006 (REACH), it is considered justified to omit the Flammability (Contact with Water) and Pyrophoric Properties of Solids and Liquids studies, also required under section 7.10 of Annex VII, on the basis that the testing does not appear to be scientifically necessary. The chemical structure of the test material contains no groups which would indicate potential reactivity with water or pyrophoric properties. In addition, experience of handling the material and the known chemical and physical properties of the substance suggest that it is not pyrophoric and is not flammable in contact with water.
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. 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).
