SOURCE OF TEST MATERIAL
- Lot No.: 1782

Key result

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

No main test was performed following the results of the preliminary test.

Interpretation of results:

GHS criteria not met

Conclusions:

The preliminary screening test did not indicate flammable properties. Because of the result of the preliminary test, lithium fluoride is classified as non-flammable.

Executive summary:

The preliminary screening test according to UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, did not indicate flammable properties. Because of the result of the preliminary test, lithium fluoride is classified non-flammable.

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

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. Because of the results of the preliminary test, lithium fluoride is not considered highly flammable.
The chemical structure of lithium fluoride 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 fluoride is not pyrophoric (Ref.: R.7a: Guidance on information requirements and chemical safety assessment, Endpoint specific guidance, Version 5.0, December 2016 (EU-Document)).

Lithium fluoride does not meet the criteria for a self-heating substance. Therefore, no experimental determination of self heating properties was carried out.

Section 2.4.2 of Guidance on the application on the CLP Criteria states as follows:  “Aerosols, this means aerosol dispensers, are any non-refillable receptacles made of metal, glass or plastics and containing a gas compressed, liquefied or dissolved under pressure, with or without a liquid, paste or powder, and fitted with a release device allowing the contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid state or in a gaseous state.” Thus, as the substance does not meet the definition for aerosol, the test for aerosols was waived.

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.
