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:
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:
not specified
Key result
Test procedure:
burning rate test over 100 mm length
Burning time:
>= 94 - <= 159 s
Remarks on result:
other: burning times over 100 mm were never less than 45 seconds upon testing 6 times

The screening test resulted in a burning rate shorter than 4 minutes for 200 mm. Therefore the full burning rate test was performed. The sample burns, melts and flows out over the base plate. Burning times over 100 mm are shown in the table below:

Burning times over 100 mm of test substance were never less than 45 seconds. Therefore the test substance was not considered as highly flammable.

Conclusions:
Under the study conditions, the test substance was considered as not highly flammable.
Executive summary:

A study was conducted to determine the flammability of the test substance, C18 TMAC (Purity: 99.2%) according to EU Method A.10. A preliminary and a full study were performed. The screening test resulted in a burning rate shorter than 4 minutes for 200 mm. Therefore the full burning rate test was performed 6 times. Burning times over 100 mm of test substance were never less than 45 seconds. Under the study conditions, the test substance was considered as not highly flammable (Kamp, 2012).

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).
