Reference 1

Endpoint:

flammable solids

Type of information:

experimental study

Adequacy of study:

key study

Study period:

24 July 2019

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Version / remarks:

31 May 2008

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

No correction for purity of the test material was applied.
The test material was considered not to be a metal or metal-alloy.

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

In the preliminary test the test material melted and could not be ignited. The molten test material did not flame.

Based on the results of the preliminary test, no main test was required.

Interpretation of results:

other: not classified according to EU criteria

Conclusions:

Under the conditions of the preliminary test, the test material could not be ignited. The test material is therefore considered to be non-flammable.

Executive summary:

A flammability (solids) study was conducted with the test material, following methods prescribed in the standardised guideline, EU Method A.10, and under GLP conditions.

In the preliminary test the test material melted and could not be ignited. The molten test material did not flame.

Based on the results of the preliminary test, no main test was required and the test material can be considered to be non-flammable.

Reference 2

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 experience in production or handling shows that the substance does not react with water, e.g. the substance is manufactured with water or washed with water

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1, the study does not need to be conducted as, based on experience in handling and use and the chemical structure, flammability on contact with water is not to be expected.

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

Justification for type of information:

JUSTIFICATION FOR DATA WAIVING
In accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1, the study does not need to be conducted as, based on experience in handling and use and the chemical structure, pyrophoric properties are not to be expected.

Description of key information

Based on the results of the flammability (solids) preliminary test, no main test was required and the test material can be considered to be non-flammable.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammability (solids)

A flammability (solids) study was conducted with the test material, following methods prescribed in the standardised guideline, EU Method A.10, and under GLP conditions.

In the preliminary test the test material melted and could not be ignited. The molten test material did not flame.

Based on the results of the preliminary test, no main test was required and the test material can be considered to be non-flammable.

Flammability (contact with water)

In accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1, the study does not need to be conducted as, based on experience in handling and use and the chemical structure, flammability on contact with water is not to be expected.

Flamability (pyrophoricity)

In accordance with Regulation (EC) No 1907/2006, Annex XI, Section 1, the study does not need to be conducted as, based on experience in handling and use and the chemical structure, pyrophoric properties are not to be expected.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the substance does not require classification with respect to flammability.
