2009-07-14 to 2009-07-21
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
other: Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part 34.4.1, Test O.1: Test for oxidizing solids
Deviations:
no
GLP compliance:
yes (incl. QA statement)
Remarks:

Contact with:
powdered cellulose
Duration of test (contact time):
<= 3 min
Sample tested:
other: not specified (migrated information) mean burning time of the 3:2 potassium bromate/cellulose mixture
Parameter:
other: mean burning time of the 3:2 potassium bromate/cellulose mixture
Result:
21 s
Remarks on result:
other: The mean of five tests on the mixture of potassium bromate with cellulose in the ratio 3:2 is reported.
Sample tested:
other: not specified (migrated information) mean burning time of the 2:3 potassium bromate/cellulose mixture
Parameter:
other: mean burning time of the 2:3 potassium bromate/cellulose mixture
Result:
66 s
Remarks on result:
other: The mean of five tests on the mixture of potassium bromate with cellulose in the ratio 2:3 is reported.
Sample tested:
other: not specified (migrated information) mean burning time of the 3:7 potassium bromate/cellulose mixture
Parameter:
other: mean burning time of the 3:7 potassium bromate/cellulose mixture
Result:
128 s
Remarks on result:
other: The mean of five tests on the mixture of potassium bromate with cellulose in the ratio 3:7 is reported.
Sample tested:
other: not specified (migrated information) mean burning time of the 1:1 test item/cellulose mixture
Parameter:
other: mean burning time of the 1:1 test item/cellulose mixture
Result:
221 s
Remarks on result:
other: The mean of five tests on the mixture of the test item with cellulose in the ratio 1:1 is reported.
Sample tested:
other: not specified (migrated information) mean burning time of the 4:1 test item/cellulose mixture
Parameter:
other: mean burning time of the 4:1 test item/cellulose mixture
Result:
323 s
Remarks on result:
other: The mean of five tests on the mixture of the test item with cellulose in the ratio 4:1 is reported.

Due to the fact that both mixtures of the test item with cellulose (4:1 and 1:1) have higher mean burning times compared to the reference mixture in the ratio 3:7, it is concluded that the test item has no oxidizing properties.

Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Conclusions:
The test item molybdenum trioxide does not meet the classification criteria for oxidizing properties in the sense of the Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part 34.4.1 (Test O.1).
The test item molybdenum trioxide does not meet the classification criteria for oxidizing properties in accordance with Regulation (EC) No. 1272/2008 on the classification, labelling and packaging of substances and mixtures ("CLP Regulation").

Description of key information

In a test for oxidising properties (acc. to the Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part 34.4.1, Test O.1) both mixtures of the test item MoO3 with cellulose (4:1 and 1:1) had higher mean burning times compared to the reference mixture in the ratio 3:7. It is concluded that the test item pure MoO3 has no oxidizing properties.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

Justification for classification or non-classification

In a test for oxidising properties (acc. to the Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part 34.4.1, Test O.1) both mixtures of the test item MoO3 with cellulose (4:1 and 1:1) had higher mean burning times compared to the reference mixture in the ratio 3:7. It is concluded that the test item pure MoO3 has no oxidizing properties. Thus, no hazard classification as an oxidising solid is required.
