Test number

Time of burning [s]

Comments

Test-1

-

Sample melted in the place of applying the
flame of burner. Sample did not burn.
Time of applying the flame of burner: 30, 60,
120 s.
Result: NEGATIVE

Test-2

-

Test-3

-

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


Interpretation of results:
not classified based on GHS criteria
Remarks:
EU criteria.
Conclusions:
The sample did not ignite after 30, 60 or 120s. Therefore, the test item is not flammable.
Executive summary:

The flammability of the test item was determined according to EU Method A.10 (GLP study). The substance was formed into an unbroken strip or powder train about 250 mm long by 20 mm wide by 10 mm high on a non-combustible, non-porous and low heat-conducting base plate, and a hot flame was applied to one end of the powder train for up to 2 minutes. The sample did not ignite after 30, 60 or 120s; it melted in the place where the flame was applied. Therefore, the test item was found to be not flammable according to test A.10 criteria.

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
The substance is not classified as flammable in contact with water based on the chemical structure and the experience in handling / use which shows that the substance does not react with water.
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
Practical experience in manufacture and handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures.

Description of key information

Flammability: Key study. Method according to EU Method A.10, GLP study. The test item is not flammable.
Pyrophoric properties: Data waiving (study scientifically not necessary / other information available). Practical experience in manufacture and handling shows that the substance does not ignite spontaneously on coming into contact with air at normal temperatures.
Flammability in contact with water: Data waiving (study scientifically not necessary / other information available): The substance is not classified as flammable in contact with water based on the chemical structure and the experience in handling / use which shows that the substance does not react with water.

Key value for chemical safety assessment

Flammability:
not classified
