Comments

Test-1

-

After the ignition the sample charred only
in the place of applying the flame of burner. The sample did not ignite. Time of applying the flame of burner: 30, 60, 120 s.

Result: NEGATIVE

Test-2

-

Test-3

-

 

Since the result is negative, it is not necessary to go to the next stage of determination.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item is not highly flammable according to test A.10 criteria.
Executive summary:

The study of determination of flammability was performed according to the EU Method A.10, following GLP. After application of the flame of burner for 30, 60 and 120 seconds, the sample does not ignite but it melts. The preliminary results were negative and therefore, it was not necessary to go to the next stage of determination. The test item is not highly flammable in accordance with test A.10 criteria.

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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
Study scientifically not necessary / other information available. The study does not to be conducted because the test 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. The test was not performed experimentally because practical experience exists at the sponsor and the test facility, e.g. when handling small amounts of the test substance repeatedly in air during testing. The test substance is therefore regarded as not being pyrophoric.
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
Justification for type of information:
JUSTIFICATION FOR DATA WAIVING
Study scientifically not necessary / other information available. Flammability in contact with water: The practical experience of the sponsor and the test facility shows that no gases are developed, when the test substance is in contact with water. The test substance is therefore regarded as not being flammable in contact with water.

Description of key information

Flammability: Key study. EU Method A.10. GLP study. The test item is not highly flammable.

Pyrophoric properties: Data waiving (study scientifically not necessary / other information available). 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.

Flammability in contact with water: Data waiving (study scientifically not necessary / other information available). The study not need to be conducted because the experience in production of handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water.

Key value for chemical safety assessment

Flammability:
not classified

Flammability in contact with water: Data waiving (study scientifically not necessary / other information available). The study not need to be conducted because the experience in production of handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water.

Justification for classification or non-classification

Based on the available information, the test item is not classified for flammability according to CLP Regulation (EC) no. 1272/2008.
