Test number

Time of burning [s]

Comments

Test-1

-

The sample only melted 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

-

The result of the preliminary test is negative, it is not necessary to go to the next stage of determination.

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

The study of determination of flammability was performed according to the EU Method A.10, following the Principles of 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 no 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 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. Practical experience in manufacture and handling shows that the substance does not ignite apontaneously on coming into contact with air at normal temperatures.
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 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.

Description of key information

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

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.

 

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. Practical experience in manufacture and handling shows that the substance does not ignite apontaneously on coming into contact with air at normal temperatures.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Key study: The study of determination of flammability was performed according to the EU Method A.10 (GLP study). The preliminary results were negative and therefore, it was not necessary to go to the next stage of determination. The test item was not highly flammable in accordance with test A.10 criteria.

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.
