Link to relevant study record(s)
- Endpoint:
- flammable solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- July 1994 - February 1995
- 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
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- 900 s
- Remarks on result:
- other: propagation over a distance of 200 mm was about 15 min (> 4 min).
- Interpretation of results:
- not classified based on GHS criteria
- Remarks:
- EU criteria.
- Conclusions:
- At the preliminary test the time of combustion propagation over a distance of 200 mm was about 15 minutes (>4 minutes).
The test substance should not be considered highly flammable and therefore no further tests were carried out. - Executive summary:
Flammability study was carried out according to EU Method A 10.
At the conditions of the preliminary test, the time of combustion propagation over a distance of 200 mm was about 15 minutes (>4 minutes). The test substance should not be considered highly flammable and therefore no further tests were carried out.
- Endpoint:
- substances / mixtures which in contact with water emit flammable gases
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- March 1995 - May 1995
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.12 (Flammability (Contact with Water))
- Deviations:
- no
- GLP compliance:
- yes
- Key result
- Test procedure:
- step 4
- Identity of evolved gas:
- not applicable as no gas evolved
- Remarks on result:
- no reaction with water observed
- Remarks:
- No significant gas evolution observed.
- Interpretation of results:
- GHS criteria not met
- Remarks:
- In contact with water does not liberate highly flammable gases (EU criteria).
- Conclusions:
- No significant gas evolution was observed in contact with water.
- Executive summary:
The flammability in contact with water test was carried out according to EU Method A 12.
During the contact of the test substance with water (distilled water at 20ºC for 7 hours) no significant gas evolution was observed.
The test substance in contact with water does not liberate highly flammable gases.
- Endpoint:
- pyrophoric solids
- Data waiving:
- other justification
- 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
- other:

At the preliminary test the time of combustion propagation over a distance of 200 mm was about 15 minutes (>4 minutes).
Description of key information
Flammability: Key study: Test method according to EU Method A 10. GLP study. The test substance was considered to be non-flammable.
Flammability in contact with water: Key study: Test method according to EU Method A 12. GLP study. The test substance in contact with water does not liberate highly flammable gases.
Pyrophoricity: Data waiving (other justification): There are no functional groups within the test item molecule that could cause pyrophoricity 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).
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
Flammability: Key study: Test method according to EU Method A 10. GLP study. The test substance was considered to be non-flammable.
Flammability in contact with water: Key study: Test method according to EU Method A 12. GLP study. The test substance in contact with water does not liberate highly flammable gases.
Pyrophoricity: Data waiving (other justification): There are no functional groups within the test item molecule that could cause pyrophoricity 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 information on flammability, the substance is considered to be non-flammable and non-pyrophoric solid; therefore, the substance is not classified.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
