- Conclusions:
- The test substance did not show any self heating properties, when using a 100 mm sample cube and 1000 mL at 140 °C.
- Executive summary:
The self heating properties of the test substance were assessed in accordance with UN test N.4. A 100 mm (1000 mL) cube made of stainless steel net with a mesh opening of 0.005 mm was filled with the sample material and then housed in an additional cubic container made of stainless steel net with a mesh opening of 0.60 mm. The cube was placed into an oven set to the desired test temperature. The temperature of the sample and oven were monitored and recorded for a minimum of 24 hours after the oven reached the desired test temperature ± 2 °C or until a positive result was obtained.
The next test was performed using a 2000 mL beaker and filling to the 1000 mL level, because the sample appeared to melt and leak through the basket.
The sample did not obtain a temperature >= 60 °C above the oven temperature within the 24 hour test period when tested at 140 °C in both cube and beaker.
Based on the above test results, the following conclusion was made:
The test substance did not appear to be a Division 4.2 Self-Heating Substance, as defined by UN/DOT criteria. A negative result was obtained in testing using a 100 mm sample cube and 1000 mL at 140 °C, when the UN Test N.4, Test Method for Self-Heating Substances was performed on the material.
- Endpoint:

- 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

No main test was performed following the results of the preliminary test.
No main test was performed following the results of the preliminary test.
The sample did not obtain a temperature >= 60 °C above the oven temperature within the 24 hour test period when tested at 140 °C in the 100 mm cube, but the sample appeared to have melted and leaked through the basket and it was unknown if the thermocouple was in contact with the sample. The next test was performed using a 2000 mL beaker and filling to the 1000 mL level, because the sample appeared to melt and leak through the basket.
The sample did not obtain a temperature >= 60 °C above the oven temperature within the 24 hour test period when tested at 140 °C in the 1000 mL beaker. No further testing was performed. The sample appeared to have melted then hardened.
Description of key information
The preliminary screening tests according to UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria with lithium acetate anhydrous and lithium acetate dihydrate did not indicate flammable properties or self heating properties. Therefore both anhydrous and the hydrated form of the test substance are classified as non-flammable. Furthermore, the substance has no pyrophoric properties and does not liberate flammable gases in contact with water.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
The preliminary screening test according to
UN Recommendations on the Transport of Dangerous Goods, Manual of Tests
and Criteria, did not indicate flammable properties or self heating
properties. Because of the results of the preliminary tests, lithium
acetate is not considered highly flammable.
The chemical structure of lithium acetate does not contain groups, which
may lead to the conclusion that the test substance is capable of
developing a dangerous amount of (flammable) gas in contact with water.
Further, it can be concluded that lithium acetate is not pyrophoric
(Ref.: R.7a: Guidance on information requirements and chemical safety
assessment, ECHA-Guidance (Version 5, December 2016)). The experience in
handling and use does not indicate flammability upon contact with water
or pyrophoric properties.
Justification for classification or non-classification
In accordance with Annex I, Section 2.1, Section 2.2, Section 2.3, Section 2.7, Section 2.9, Section 2.10 Section 2.11, Section 2.12 of Regulation (EC) No 1272/2008 and UN GHS Rev 6 (2015) the substance has not to be classified as readily combustible solid in class 4 Division 4.1 or self-heating substance in Class 4 Division 4.2, pyrophoric liquid in class 4 Division 4.2, flammable gases in class 2 or as aerosol in class 2.
