- GHS criteria not met
- Conclusions:
- The test item was determined to be not oxidising under the test conditions of method A.21 of Commission Regulation (EC) No. 440/2008.
- Executive summary:
A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.21 in order to determine whether the test item has oxidising properties. The test item was mixed 1:1 with fibrous cellulose and introduced into a pressure vessel. The mixture was heated in the pressure vessel and the rate of pressure rise was determined. The time taken for the pressure rise from 690 kPa to 2070 kPa above atmosphere was noted. In parallel the pressure rise time of a reference mixture was determined (1:1 mixture, by mass, of 65 % nitric acid and cellulose). The pressure rise times of both mixtures were tested five times each. Due to the fact that the 1:1 mixture of test item and cellulose had a mean pressure rise time of 34.01 s, which was higher than that of the reference mixture (5.06 s) the test item was considered to have no oxidising properties and no further reference mixtures had to be measured.

Individual results
Test series of at least 5 tests each were performed with the test itemand with 65 % nitric acid in 1:1 mixture, by mass, with cellulose. The cellulose was dried at 105 ± 5 °C until the weight was constant. Due to the partiele size of the cellulose grinding and sieving was not necessary.
Reference substance
In Table 1 the pressure rise times from 690 kPag to 2070 kPag for the 1:1 mixtures, by mass, of 65 % (w/w) nitric acid and cellulose are presented. The given values were rounded.

The values of the pressure rise times in table 1 are obtained from the unrounded values. The mean pressure rise time was 5.06 s. All measured values are within the tolerable range of +30 % (3.54 - 6.57 s) of the mean pressure rise time.
Test item
As the test item has a high vapour pressure the mixing time was reduced. In Table 2 the pressure rise times from 690 kPag to 2070 kPag for the 1:1 mixtures, by mass, of the test item and cellulose are shown. The given values were rounded. In four tests the pressure did not reach 2070 kPag.

The mean pressure rise time was 34.01 s.
Due to the fact that the 1:1 mixture, by mass, of test item and cellulose had a mean pressure rise time higher than that of a 1:1 mixture, by mass, of 65 % (w/w) nitricacid and cellulose the test item had no oxidising properties and no further reference mixtures had to be measured.
Description of key information
The test item was determined to be not oxidising.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Oxidising solids (reference 4.15-1)
The test item is a solid at ambient conditions. This hazard class is only applicable for liquids. Thus, the substance was not considered for classification as oxidising liquid.
Oxidising liquids (reference 4.15-2)
A study was performed in accordance with Commission Regulation (EC) No. 440/2008, method A.21 in order to determine whether the test item has oxidising properties. The test item was mixed 1:1 with fibrous cellulose and introduced into a pressure vessel. The mixture was heated in the pressure vessel and the rate of pressure rise was determined. The time taken for the pressure rise from 690 kPa to 2070 kPa above atmosphere was noted. In parallel the pressure rise time of a reference mixture was determined (1:1 mixture, by mass, of 65 % nitric acid and cellulose). The pressure rise times of both mixtures were tested five times each. Due to the fact that the 1:1 mixture of test item and cellulose had a mean pressure rise time of 34.01 s, which was higher than that of the reference mixture (5.06 s) the test item was considered to have no oxidising properties and no further reference mixtures had to be measured (reference 4.15 -2).
Oxidising gases (reference 4.15-3)
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 gas.
Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No. 1272/2008
Based on the results of the performed study according to method A.21 of Commission Regulation (EC) No. 440/2008 and taking into account the provisions laid down in Regulation (EC) No. 1272/2008, as amended for the tenth time in Regulation (EC) No. 2017/776, the substance is not considered to be classified for oxidising properties.
