Key result

Test procedure:

burning rate test: preliminary screening test

Remarks on result:

other: The sample does not ignite after 30, 60 nor 120 minutes.

After applying the flame of burner the sample does not ignite but it melts. Application time of the ignition source was 30, 60 and 120 seconds. The preliminary results were negative, therefore it was not necessary to go to the next stage of determination. Test item was not highly flammable in accordance with test EU Method A.10. criteria.

Interpretation of results:

GHS criteria not met

Remarks:

Non flammable

Conclusions:

Test item was not highly flammable in accordance with test EU Method A.10. criteria.

Executive summary:

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

Reference 2

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: 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.

Reference 3

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 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. Moreover, according to the auto-ignition study on test item, the substance does not ignite in air at ca. 20 °C and even not at temperatures up to 400 °C. The test substance is therefore regarded as not being pyrophoric.

Description of key information

Key study: Test method EU Method A.10. GLP study. Test item was not highly flammable in accordance with test criteria.

Flammability in contact with water: Data waiving: Based on experience, the substance is  not regarded as flammable in contact with water.

Pyrophoricity: Data waiving: Based on experience, the substance is regarded as not pyrophoric.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Key study: Flammability (solids) test was performed according to the EU Method A.10. After application of the flame of burner for 30, 60 and 120 seconds (triplicate), the sample does not ignite but it melts. The preliminary results were negative. Test item was not highly flammable in accordance with test EU Method A.10. criteria.

Flammability in contact with water: Data waiving : 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.

Pyrophoricity: Data waiving: 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. Moreover, according to the auto-ignition study on test item, the substance does not ignite in air at ca. 20 °C and even not at temperatures up to 400 °C. The test substance is therefore regarded as not being pyrophoric.

Justification for classification or non-classification

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