Administrative data
Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 1996-06-19 to 1996-07-11
- 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:
- OJ No. L383A, 29.12.92
- Deviations:
- no
- GLP compliance:
- yes
- Specific details on test material used for the study:
- Batch No.: Chichibu Lot 950704
Purity: 95.7% - Key result
- Test procedure:
- burning rate test: preliminary screening test
- Remarks on result:
- other: The flame failed to propagate along the pile into the timing zone.
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- The test substance was not highly flammable under the conditions of the test.
- Executive summary:
The flammability of powders, granules or pastes is determined using a test mould and an ignition source.
The test flame was held in position for 2 minutes during which time the test substance melted to a brown liquid, and then changed colour to a black liquid. The sample appeared to boil as it burnt with an orange flame, which slowly diminished after the ignition source was removed and finally died away after 5 minutes. The flame failed to propagate along the pile into the timing zone.
Under the terms of the Directive, extended testing was not required because the flame did not propagate along the pile.
The test substance was not highly flammable under the conditions of the test.
- 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:
- 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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

Description of key information
Flammable solids:
The test item has been determined to be not highly flammable as it did not propagate combustion over 200 mm.
Pyrophoric solids:
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.
Substances / mixtures which in contact with water emit flammable gases:
The study does not need to be conducted because the organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied.
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Justification for classification or non-classification
Flammable solids:
The test sample appeared to boil as it burnt with an orange flame, which slowly diminished after the ignition source was removed and finally died away after 5 minutes. The flame failed to propagate along the pile into the timing zone.
Therefore in accordance with Regulation (EC) No. 1272/2008 section 2.7.2.1, this substance should not be classified as flammable solids.
Pyrophoric solids:
The substance is known to be stable at room temperature for prolonged periods of time (days).
Therefore, in accordance with Regulation (EC) No. 1272/2008 section 2.10.4, the classification procedure for pyrophoric solids need not be applied.
Substances / mixtures which in contact with water emit flammable gases:
The chemical structure of the substance or mixture does not contain metals or metalloids.
Therefore in accordance with Regulation (EC) No. 1272/2008 section 2.12.4.1(a), the classification procedure for this class need not be applied.
