Conclusions:
The test item was not oxidizing.
Executive summary:

The oxidizing test of the test substance was measured by the solid oxidizing test apparatus according to UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids).

Test item mixture I and test item mixture II burnt. The mean burning time of test item mixture I (1:1) and II (4:1) were 2'54" and 4'08", the mean burning time of standard mixture I (3:7) were 1'45".

Both of the burning times of test item mixture I and test item mixture II were larger than that of standard mixture I, the test item should not be classified in Division 5.1, not oxidizing.

Description of key information

The test item was not oxidizing.

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

The oxidizing test of the test substance was measured by the solid oxidizing test apparatus according to UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids).

Test item mixture I and test item mixture II burnt. The mean burning time of test item mixture I (1:1) and II (4:1) were 2'54" and 4'08", the mean burning time of standard mixture I (3:7) were 1'45".

Both of the burning times of test item mixture I and test item mixture II were larger than that of standard mixture I, the test item should not be classified in Division 5.1, not oxidizing.

Justification for classification or non-classification

The mean burning time of test item mixture I (1:1) and II (4:1) were 2'54" and 4'08", the mean burning time of standard mixture I (3:7) were 1'45".

In accordance with Regulation (EC) No. 1272/2008 section 2.14 Table 2.14.1, the substance should not be classified for oxidising solids.
