Key result

Test procedure:

100 mm sample cube at 140°C

Max. temp. reached:

140

Induction time (h):

24

Result:

negative outcome (no effect observed)

A negative result was obtained. No spontaneous ignition occurred and no exothermic effect of the test item was observed. It demonstrated that the test item is “not a self-heating substance”.

According to the UN guideline, no further testing is required.

After the experiment, the consistency of the sample was unchanged, i.e. no reaction and/or decomposition of the test item was observed.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that Lithium Trifluoromethanesulfonate is not a self-heating substance.

Executive summary:

Self-heating of Lithium Trifluoromethanesulfonate was determined in accordance with UN Test N.4 “Test Method for Self-heating Substances”, under GLP compliance.

From the negative result obtained at 140°C using a 10 cm sample cube, it was concluded that Lithium Trifluoromethanesulfonate is not a self-heating substance.

Lithium Trifluoromethanesulfonate is not classified based on GHS criteria.

The individual measurements were obtained with an accuracy of < 0.02 g/cm3. According to the guideline, the density of the test item is given as the mean value.

Density of the test item

	Test 1	Test 2	Mean
Density [g/cm3]	2.132	2.141	2.14

A gas comparison stereopycnometer was used for the determination of the density and the relative density of Lithium Trifluoromethanesulfonate.

The density of the test item at 20 °C was 2.14 g/cm3. The relative density was 2.14.

Conclusions:

A gas comparison stereopycnometer was used for the determination of the density and the relative density of Lithium Trifluoromethanesulfonate.
The density of the test item at 20 °C was 2.14 g/cm3. The relative density was 2.14.

Executive summary:

Measurement of the density and the relative density of Lithium Trifluoromethanesulfonate was performed using a gas comparison stereopycnometer according to standardised guidelines (OECD TG 109, EU A.3 and OPPTS 830.7300) under GLP conditions.

The density of the test item at 20 °C was 2.14 g/cm3. The relative density was 2.14.
