Endpoint:
flammable solids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
April 2012
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:
no
Key result
Test procedure:
burning rate test: preliminary screening test
Burning time:
ca. 196 - ca. 240 s
Remarks on result:
other: The flame extinguished by itself with only 1-2 cm progress. Hence full burning rate test was not needed.

The screening test resulted in a burning time of 3 minutes and 16 seconds, then the flame extinguished by itself with only 1-2 cm progress. The screening test was repeated once again. The sample burned for at least 4 minutes with a progress of only a few cm. Therefore the full burning rate test was not needed. The test substance is not considered as highly flammable.

Interpretation of results:
other: not classified based on CLP criteria
Conclusions:
 Under the study conditions, the test substance was considered to be non-flammable.

Executive summary:

The flammability of the test substance, C16-18 and C18-unsatd. TMAC (purity not specified) was determined according to EU Method A.10. The screening test resulted in a burning time of 3 minutes and 16 seconds or 4 minutes (on repetition), then the flame extinguished by itself with only 1-2 or few cm’s progress. Therefore the full burning rate test was not needed. Under the study conditions, the test substance was considered to be non-flammable (Kamp, 2012).

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 liquids
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

Description of key information

The flammability of the test substance was determined according to EU Method A.10 (Kamp, 2012). 

Key value for chemical safety assessment

Flammability:
non flammable

Additional information

Justification for classification or non-classification

The test substance was found to be non-flammable in a guideline test, thus no classification is required for this endpoint according to EU CLP criteria (Regulation EC 1272/2008).
