- Specific details on test material used for the study:
- Test item
The test item was sieved. The fraction with a particle size of less than 500 µm was tested.
The test item was dried at 50 °C under vacuum (app. 100 mbar) until the weight remained constant, cooled and kept in a desiccator until the test.
Potassium bromate
Potassium bromate was ground and sieved. The fraction with particles ranging from 150 µm to 300 µm was used as reference item for the tests.
Potassium bromate was dried at 65 °C until the weight remained constant, cooled and kept in a desiccator until the test.
Cellulose powder
Due to the fact that the particle size of the Cellulose powder was already <90 µm the Cellulose had not to be ground and/or sieved. The mean fiber length was approximately 60 µm and the residual moisture < 7.5 % (5.25 %).
The Cellulose powder was dried at 105 °C until the weight remained constant and the water content was less than 0.5% by dry mass, cooled and kept in a desiccator until the test. - Contact with:
- powdered cellulose
- Duration of test (contact time):
- > 180 s
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Sample tested:
- reference: 3:7 mixture potassium bromate + cellulose
- Parameter:
- mean burning time
- Result:
- 109 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The burning times of mixtures of the test item with cellulose (4:1 and 1:1) were higher than the burning time of the reference mixture of potassium bromate and cellulose (3:7). Based on the test results, the test item does not need to be classified as oxidizing solid.
UN Transport Regulation
The test item does not need to be classified as oxidizing solid in Division 5.1 according to the UN Transport Regulation.
GHS and Regulation EC 1272/2008 (CLP Regulation), Annex 1: 2.14
The test item does not need to be classified as oxidizing solid according to GHS and EC 1272/2008 (CLP Regulation) Annex 1: 2.14.
Reference
Residual Moisture
The test item contains a residual moisture of <0.1 wt.-%, which was determined by drying the test item under vacuum (reduced pressure of approximately 100 mbar) at a temperature of 50 °C.
The reference item potassium bromate contains a residual moisture of 0.01 wt.-%, which was also determined by drying the test item under vacuum.
The reference item cellulose contains a residual moisture of 5.25 wt.-%, which was also determined by drying the test item under vacuum.
