 Results

In contact with the flame of the gas burner the test item melted and turned into a white residue. White smoke was observed. After removal of the ignition source, no propagation of combustion of the test item was observed.

 Conclusion

The preliminary screening test was performed for the determination of the flammability of the test item Bis(hexamethylene)triamine.

No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, based on the result of the preliminary test performance of the burning rate test is not required. Based on the results obtained, the test item is considered ‘not highly flammable’.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

Based on the result of the preliminary screening test (UN Test N.1. / EU method A.10), the test item is not a readily combustible solid (UN Test N.1.) and the test item is considered ‘not highly flammable’ (EU method A.10).

Executive summary:

The submission substance was tested for flammability of solids according to UN Test N.1. and EU method A.10 compliant with GLP.

A preliminary screening test was performed for the determination of the flammability of Bis(hexamethylene)triamine. No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained, the test item is not a readily combustible solid (UN Test N.1.) and is considered to be ‘not highly flammable’ (EU method A.10). Accordingly, there are no classification requirements with regard to flammable solids.

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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

the study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture

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

Endpoint:

self-heating substances / mixtures

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 completely molten at 160°C

Description of key information

Based on the result of the preliminary screening test (UN Test N.1. / EU method A.10), the test item is not a readily combustible solid (UN Test N.1.) and the test item is considered ‘not highly flammable’ (EU method A.10).

Key value for chemical safety assessment

Flammability:

Justification for classification or non-classification

The submission substance was tested for flammability of solids according to UN Test N.1. and EU method A.10 compliant with GLP.

A preliminary screening test was performed for the determination of the flammability of Bis(hexamethylene)triamine.No propagation of combustion of the test item along 200 mm length of the pile within 4 minutes was observed. According to the guidelines, performance of the burning rate test is not required. Based on the results obtained,the test item is not a readily combustible solid (UN Test N.1.) and is considered to be ‘not highly flammable’ (EU method A.10). Accordingly, there are no classification requirements with regard to flammable solids.

With regard to pyrophoric properties, experience from the handling and use of the substance allows to exclude pyrophoric properties (according to CLP Regulation, Annex 1, Part 2, section 2.10.4.1).

With regard to the evolution of flammable gases in contact with water, experience from the handling and use of the substance allows to exclude reaction with water to emit flammable gases, and the chemical structure of the substance does not contain metals or metalloids (according to CLP Regulation, Annex I, part 2, section 2.12.4).

With regard to self-heating, according to the Guidance on the Application of the CLP Criteria (ECHA-17-G-21-EN), substances or mixtures with a low melting point (< 160 °C) should not be considered for classification as self-heating since the melting process is endothermic and the substance-air surface is drastically reduced. The melting point of the substance is at 30.8 °C. Accordingly, self-heating is not a relevant property for the submission substance and consequently, there are no classification requirements in this regard.
