Remarks on result:

not measured/tested

Remarks on result:

not measured/tested

Preliminary test:

The test item did not ignite.

Main test:

As the test item could not be ignited in the preliminary test it should not be considered as highly flammable and no further testing was required. Therefore no main test was performed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item Imidazolhydrobromid could not be ignited. Therefore the test item is considered not to be highly flammable.

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
Testing for flammability in contact with water is not considered to be required, because the substance does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Furthermore, long-term industrial experience in practical handling of the substance shows that it does not react with water, and recent experimental testing for water solubility has also not reported any formation of gases (in accordance with section 1, Annex XI of Regulation (EC) 1907/2006).

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
Testing for pyrophoric properties of solids is not considered to be required, since this substance is stable at ambient temperature. This substance also does not contain any chemical groups that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (circa 20 °C) . Furthermore, long-term industrial experience in handling shows that the substance does not ignite in contact with air (in accordance with section 1, Annex XI of Regulation (EC) 1907/2006).

Description of key information

Flammability solid: The test item Imidazolhydrobromid could not be ignited. Therefore the test item is considered not to be highly flammable.
Pyrophoric properties:  Imidazolhydrobromid does not ignite in contact with air.
Flammability in contact with water: Imidazolhydrobromid does not ignite in contact with water.

Key value for chemical safety assessment

Flammability:

non flammable

Additional information

Pyrophoric properties

Testing for pyrophoric properties of solids is not considered to be required, since this substance is stable at ambient temperature. This substance also does not contain any chemical groups that might lead to spontaneous ignition a short time after coming in contact with air at room temperature (circa 20 °C) . Furthermore, long-term industrial experience in handling shows that the substance does not ignite in contact with air (in accordance with section 1, Annex XI of Regulation (EC) 1907/2006).

Flammability in contact with water

Testing for flammability in contact with water is not considered to be required, because the substance does not contain groups that might lead to a reaction with water or damp air, leading to the development of dangerous amounts of gas or gases which may be highly flammable. Furthermore, long-term industrial experience in practical handling of the substance shows that it does not react with water, and recent experimental testing for water solubility has also not reported any formation of gases (in accordance with section 1, Annex XI of Regulation (EC) 1907/2006).
