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

- The preliminary screening test showed that the test material burned only during the time when the gas burner was directed to the test material. The flame expired after the gas burner was turned off (after two minutes).

- After four minutes of waiting, no smouldering or burning was observed.

- The burned distance was 60 mm.

- The test material was not be considered to be highly flammable, because the burned distance was less than 200 mm and therefore no further testing was required.

Interpretation of results:

other: Not highly flammable in accordance with EU criteria

Conclusions:

Under the conditions of this study, the test material was determined to be not highly flammable.

Executive summary:

The flammability of the test material was investigated in accordance with the standardised guidelines EU Method A.10 and NF T 20-042.

The preliminary screening test showed that the test material burned only during the time when the gas burner was directed to the test material. The flame expired after the gas burner was turned off (after two minutes). After four minutes of waiting, no smouldering or burning was observed. The burned distance was 60 mm. The test material was not be considered as highly flammable, because the burned distance was less than 200 mm and therefore no further testing was required.

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 point 1 of Annex XI, it is considered justified to omit the testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not emit flammable gases in contact with water.

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 section 1.5 of REACH Annex XI, the study does not need to be performed as based on chemical structure pyrophoric properties are not to be expected. In addition, in the daily use and handling of the substance during which continuous exposure to air can occur, no spontaneous ignition is observed.

Description of key information

Flammability (solids)

Under the conditions of the study, the test material was determined to be not highly flammable.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

Flammability (solids)

The flammability of the test material was investigated in accordance with the standardised guidelines EU Method A.10 and NF T 20-042. The study was awarded a reliability score of 2 in accordance with the criteria set forth by Klimisch et al. (1997).

The preliminary screening test showed that the test material burned only during the time when the gas burner was directed to the test material. The flame expired after the gas burner was turned off (after two minutes). After four minutes of waiting, no smouldering or burning was observed. The burned distance was 60 mm. The test material was not be considered as highly flammable, because the burned distance was less than 200 mm and therefore no further testing was required.

Pyrophoricity

In accordance with point 1 of Annex XI, it is considered justified to omit the testing for pyrophoric properties. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not possess pyrophoric properties.

Flammability in contact with water

In accordance with point 1 of Annex XI, it is considered justified to omit the testing for substances or mixtures which in contact with water emit flammable gases. Testing does not appear scientifically necessary as experience in use and experience of handling the substance indicates that it does not emit flammable gases in contact with water.

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.
