- Key result
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- burning rate
- Remarks on result:
- mixture does not ignite and burn
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item has no oxidizing properties under the test conditions.
- Executive summary:
An experimental study was conducted according to EU Method A.17. to determine the oxidizing properties of the test item. The test item was mixed with Cellulose in different ratios (10 - 90 %). None of the investigated mixtures with Cellulose did burn. Due to the test results the test item does not have to be classified as oxidizing solid.
- Endpoint:
- oxidising liquids
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid
- Endpoint:
- oxidising gases
- Data waiving:

Referenceopen allclose all
The reference mixture was a mixture of 60 % Bariumnitrat and 40 % Cellulose. It burned with a speed rate of 1,1 mm/s. Following the singular results:
Mixture | Burning distance / Burning time / Buring speed rate |
10 % Substance / 90 % Cellulose | The amount extinguished within the start segment |
20 % Substance / 80 % Cellulose | The amount extinguished within the start segment |
30 % Substance / 70 % Cellulose | The amount extinguished within the start segment |
40 % Substance / 60 % Cellulose | The amount extinguished within the start segment |
50 % Substance / 50 % Cellulose | The amount extinguished within the start segment |
60 % Substance / 40 % Cellulose | The amount extinguished within the start segment |
70 % Substance / 30 % Cellulose | The amount extinguished within the start segment |
80 % Substance / 20 % Cellulose | The molten mass was not ignitable |
90 % Substance / 10 % Cellulose | The molten mass was not ignitable |
The test item has no oxidizing properties when tested according to this procedure.
Description of key information
The test item has no oxidizing properties.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Oxidising gases
The test item is a solid at ambient conditions. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as oxidising gases.
Oxidising liquids
The test item is a solid at ambient conditions. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as oxidising liquids.
Oxidising solids
An experimental study was conducted according to EU Method A.17. to determine the oxidizing properties of the test item. The test item was mixed with Cellulose in different ratios (10 - 90 %). None of the investigated mixtures with Cellulose did burn. Due to the test results the test item does not have to be classified as oxidizing solid.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
Based on the chemical structure and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for the seventeenth time in Regulation (EU) 2021/849, and UN GHS Rev 9 (2021) the substance is not considered to be classified as oxidising gas, oxidising liquid or oxidising solid in class 5 Division 5.1.
