Test procedure:

100 mm sample cube at 140°C

Max. temp. reached:

140

Result:

negative outcome (no effect observed)

Determination of the Dry Content

The residual moisture of the test item after 52 h was determined to 0.47 wt. % (dry content: 99.53 wt. %). No further increase of the residual moisture was observed after an additional drying time of 17 h (total drying time: 69 h). The dry content remained constant at 99.5 weight%.

 

UN-Test. N.4: Bowes - Cameron - Cage Test

Test in the 10 cm cube sample at a oven temperature of 140 °C

No exothermal reaction of the test item at a temperature of 140 °C was observed. No reaction of the test item was observed until the end of the study (mass loss: 0.7 wt.%).

The temperature of the test item did not exceed 200 °C during the whole test. The test item is not classified in Division 4.2 (a negative result was obtained in the test using a 10 cm cube sample at 140 °C).

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is not classified according to UN Test N.4 Bowes - Cameron - Cage test (a negative result was obtained in the test using a 10 cm cube sample at 140 °C).

Remarks:

HESSISCHES MINISTERIUM FÜR UMWELT, LANDWIRTSCHAFT UND FORSTEN, Wiesbaden, Germany

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

Remarks:

The test item could not be ignited with a flame. The test item melted.

The test item could not be ignited with a flame. The test item melted.

A main test was therefore not necessary.

 

Final Results

The test item is not a highly flammable solid in the sense of the consolidated version of Council Directive 67/548/EEC Annex V, Method A. 10.

Interpretation of results:

not classified based on GHS criteria

Conclusions:

The test item is not a highly flammable solid in the sense of the consolidated version of Council Directive 67/548/EEC Annex V, Method A.10.

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

Reference 4

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 organic substance does not contain metals or metalloids and hence, the classification procedure does not need to be applied

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

Description of key information

non flammable, no pyrophoricity, no flammability on contact with water and not self-heating.

Key value for chemical safety assessment

Flammability:

not classified

Additional information

The substance could not be ignited in the preliminary burning rate test (EU Method A.10). No self-heating was observed in a 100 mm sample cube at 140 °C in a test according to UN Test N.4 (Bowes-Cameron Cage test). Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.

Justification for classification or non-classification

The available data on flammability of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification: No propagation of burning in a test according to EU Method A.10. No self-heating according to UN Test N.4 (Bowes-Cameron Cage test). Based on the chemical structure and experience in handling and use, pyrophoricity and flammability on contact with water are not expected.
