Flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water
- 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
- Study period:
- 9 May 2001 - 11 May 2001
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- Study conducted in compliance with agreed protocols, with no or minor deviations from the standard test guidelines and/or minor methodological deficiencies, which do not affect the quality of the relevant results. The study report was conclusive, done to a valid guideline and conducted under GLP conditions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.10 (Flammability (Solids))
- Deviations:
- no
- GLP compliance:
- yes
- Key result
- Test procedure:
- burning time (test type not further specified)
- 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:
- Under the conditions of the test, the test material was determined to be non-flammable in a burning rate test.
- Executive summary:
The flammability of the test material was determined using the burning rate method in a study performed under GLP conditions and in accordance with the standardised guidelines EU method A.10.
A butane gas burner was applied to the end of a pile (20 mm base and 10 mm height and 250 mm in length) of the test material for 2 minutes; the substance melted but did not ignite. The test material was determined to be non-flammable.

Results
The test material melted but did not ignite after a bunsen burner was applied to the pile for 2 minutes. The test material is not flammable.
Description of key information
Flammable solids, non flammable, burning rate test, EU Method A.10, Comb 2001.
Testing for pyrophoric properties and flammability in contact with water were omitted based on prior experience of handling the substance. The substance is not known to ignite spontaneously in contact with air or water, or emit flammable gases on contact with water. On this basis, testing for these properties was considered to be scientifically unnecessary.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Flammable Solids
The flammability of the test material was determined using the burning rate method in a study performed under GLP conditions and in accordance with the standardised guidelines EU method A.10. The study was assigned a reliability score of 1, reliable without restrictions, in line with the principles of Klimisch et al. (1997).
A butane gas burner was applied to the end of a pile (20 mm base and 10 mm height and 250 mm in length) of the test material for 2 minutes; the substance melted but did not ignite. The test material was determined to be non-flammable.
Pyrophoric Properties
In accordance with Section 1 (Testing Does Not Appear Scientifically Necessary), Annex XI (General Rules for Adaptation of the Standard Testing Regime Set Out in Annexes VII to X) of Regulation EC No. 1907/2006 (REACH), based on the known chemical and physical properties of the substance, its chemical structure and experience in handling the substance, the substance does not ignite spontaneously in contact with air. Testing in line with EU Method A.13 (Pyrophoric properties of solids and liquids) is applicable to solid or liquid substances, which, in small amounts, will ignite spontaneously a short time after coming into contact with air at room temperature (circa 20 °C). Testing is therefore omitted as it does not appear scientifically necessary.
Flammability in Contact with Water
In accordance with Section 1 (Testing Does Not Appear Scientifically Necessary), Annex XI (General Rules for Adaptation of the Standard Testing Regime Set Out in Annexes VII to X) of Regulation EC No. 1907/2006 (REACH), based on the known chemical and physical properties of the substance, its chemical structure and experience in handling the substance, testing in line with EU Method A.12 (Flammability in contact with water) is expected to produce a negative result. The substance is predicted to produce no significant reaction with water at 20 °C and to emit no flammable gases. Testing is therefore omitted as it does not appear scientifically necessary. Furthermore, no adverse effects were seen in the water solubility study for this substance.
Justification for classification or non-classification
In accordance with the criteria for classification as defined in Annex I (Classification and Labelling Requirements for Hazardous Substances and Mixtures), Regulation (EC) No. 1272/2008 (CLP), the substance does not require classification for flammability.
