Specific details on test material used for the study:
Storage conditions: Room temperature in original container and tightly closed
Test procedure:
burning rate test: preliminary screening test
Remarks on result:
substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period

Preliminary Test

The test item did not ignite using a flame (min 1000 °C) as ignition source for at least 2 minutes. The test item melted.

Main Test

In the preliminary screening test the test item could not be ignited. Thus, the performance of the main test was not necessary.

Classification

The test item is classified as follows:

UN Transport Regulation:

The test item does not meet the classification criteria as readily combustible solid in Class 4 Division 4.1 according to the UN Transport Regulation.

GHS / CLP Regulation EC 1272/2008 Annex 1:2.7:

The test item does not meet the classification criteria as flammable solid, according to GHS and EC 1272/2008 (CLP Regulation) Annex 1, Section 2.7.

Interpretation of results:
GHS criteria not met
Conclusions:
Main Test
In the preliminary screening test the test item could not be ignited. Thus, the performance of the main test was not necessary.

Classification
The test item is classified as follows:

UN Transport Regulation:
The test item does not meet the classification criteria as readily combustible solid in Class 4 Division 4.1 according to the UN Transport Regulation.

GHS / CLP Regulation EC 1272/2008 Annex 1:2.7:
The test item does not meet the classification criteria as flammable solid, according to GHS and EC 1272/2008 (CLP Regulation) Annex 1, Section 2.7.
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 substance is known to be soluble in water to form a stable mixture
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

Description of key information

The test item triethylmethylammonium tetrafluoroborate is not classified as flammable solid, has no pyrophoric properties and does not emmit flammable gases in contact with water.

Key value for chemical safety assessment

Flammability:
not classified

Additional information

Flammability solids

In the preliminary screening test the test item could not be ignited. Thus, the performance of the main test was not necessary.

Flammability in contact with water

The study does not need to be conducted because the substance is known to be soluble in water to form a stable mixture. DIGIRENA SA TEMABF4 anhydrous was determined to have a water solubility of greater than 2 g/mL of water.

Pyrophoric properties

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 classification or non-classification

UN Transport Regulation

The test item does not meet the classification criteria as readily combustible solid in Class 4 Division 4.1 according to the UN Transport Regulation.

GHS / CLP Regulation EC 1272/2008 Annex 1:2.7

The test item does not meet the classification criteria as flammable solid, according to GHS and EC 1272/2008 (CLP Regulation) Annex 1, Section 2.7.
