Adequacy of study:

key study

Study period:

April - June 2020

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.10 (Flammability (Solids))

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Specific details on test material used for the study:

- Storage conditions: Controlled room temperature (15-25°C, ≤70% relative humidity), protected from light and humidity (stored in a tightly closed container)

Key result

Test procedure:

burning rate test: preliminary screening test

Burning time:

> 360 s

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 IGNITION TEST:

A hot flame from a gas burner was applied to one end of the powder train until the powder ignited (within 2 minutes). The test was performed three times, in case of the first time the laboratory fume hood air flow was operating, in case of the further occasions, the hood was turned off. The times of burning over a distance of 200 mm were measured (where was applicable).

The test item did not propagate by combustion either by burning with a flame or smouldering along 200 mm within 4 minutes, although there was a combustion taking longer than 4 minutes, therefore no further testing was performed. The combustion took longer than 4 minutes, resulting in a maximum of 0.53 mm/second as burning rate.

MAIN TEST:

Based on the results of the preliminary tests, no further testing was required.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item ignited, but the combustion took longer than 4 minutes, resulting in a maximum of 0.53 mm/second as burning rate. According to the relevant guideline, test items are considered as flammable, if the burning rate is at least 0.83 mm/second. As the combustion took longer than 4 minutes on a 200 mm powder train, the test item is considered to be non-flammable under the conditions of this test.

Executive summary:

The study was performed in accordance with EU method A.10. In trhe pretest, the test item ignited, but the combustion took longer than 4 minutes, resulting in a maximum of 0.53 mm/second as burning rate. According to the relevant guideline, test items are considered as flammable, if the burning rate is at least 0.83 mm/second. Therefore, as the combustion took longer than 4 minutes on a 200 mm powder train, the test item is considered to be non-flammable under the conditions of this test. Based on the results of the preliminary tests, no further testing was required. In addition, tests A.12 and A.13 were not conducted, as based on the chemical structure, the test item does neither react with water nor evolve any flammable gases in contact with (humid) air. Substance does not have self-heating properties. As overall conclusion, the test item was considered to be not flammable.

Description of key information

The study was performed in accordance with EU method A.10. In trhe pretest, the test item ignited, but the combustion took longer than 4 minutes, resulting in a maximum of 0.53 mm/second as burning rate. According to the relevant guideline, test items are considered as flammable, if the burning rate is at least 0.83 mm/second. Therefore, as the combustion took longer than 4 minutes on a 200 mm powder train, the test item is considered to be non-flammable under the conditions of this test. Based on the results of the preliminary tests, no further testing was required. In conclusion, the test item was considered to be not flammable.

The studies A.12 and A.13 were not performed, as the substance will hydrolyze immediately in contact with water or humid air. There are no flammable gases formed during hydrolysis. Hydrolysis was confirmed in a hydrolysis study according to OECD 111.

Key value for chemical safety assessment

Flammability:

not classified

Justification for classification or non-classification

Based on the data available the substance is not classified or labeled according to Regulation 1272/2008/EC (CLP).
