Any other information on results incl. tables
Results of the main test:
The test item charred the cellulose like concentrated sulphuric acid. The cellulose turned black during dropwise addition of the test item. While mixing test item and cellulose, the mixture became hot and yielded a black granulate with white spots. No ignition was observed. After consultation of the national reference institute (BAM, Bundesanstalt für Materialprüfung) the test is not conductable as no mixture with cellulose can be tested, because the cellulose reacts with the test item to a mixture of charred cellulose containing only residues of test item and cellulose.
The time intervals which were recorded between the lower pressure value (690 kPa) and the upper pressure value (2070 kPa) in each experiment are presented in the following table and in Attachment 1:

Expert statement on oxidising properties
Definition following EU-Method
A liquid substance or mixture is classified as oxidising if the following test criteria are met: the liquid to be tested is mixed in a 1 to 1 ratio, by mass, with fibrous cellulose and introduced into a pressure vessel. If during mixing or filling spontaneous ignition occurs, no further testing is necessary. If spontaneous ignition does not occur the full test is carried out. The mixture is heated in a pressure vessel and the mean time taken for the pressure to rise from 690 kPa to 2070 kPa above atmospheric is determined. This is compared with the mean pressure rise time for the 1:1 mixture of the reference substance(s) and cellulose. The reference is nitric acid of 65 % and analytical grade.
Following GHS:
"An oxidising liquid is a liquid which, while in itself not necessarily combustible, may, generally by yielding oxygen, cause, or contribute to, the combustion of other material."
"An oxidising gas is any gas which may, generally by providing oxygen, cause or contribute to the combustion of other material more than air does."
Results of the expert statement:
The determination of the oxidizing properties of the test item was not possible according to EU-Guideline A.21 and UN Method O.2 (GHS) after consultation of the national reference institute (BAM, Bundesanstalt für Materialprüfung) as the test item charred the cellulose. In a measurement of the mixture which was conducted regardless this fact the pressure didn’t rise above 690 kPa. A measurement with 65% nitric acid and cellulose showed correct working of the test system. The chemical structure does not contain any groups associated with oxidising properties (see Attachment2).Therefore, the test item should be considered as not oxidizing.
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The determination of the oxidizing properties of the test item wasn't possible according to UN Method O.2. The test item isn't considered as oxidizing based on its chemical structure.
- Executive summary:
The study was performed according to Method A.21 of Commission Regulation (EC) N° 440/2008 of 30 May 2008 and GLP. A deviation not affecting the quality of the study was observed.
The liquid is mixed in a 1 to 1 ratio, by mass, with fibrous cellulose and introduced into a pressure vessel. The mixture is heated in a pressure vessel and the mean time taken for the pressure to rise from 690 kPa to 2 070 kPa above atmospheric is determined. This is compared with the mean pressure rise time for the 1:1 mixture of the reference item (nitric acid 65%)and cellulose.
The test item charred the cellulose like concentrated sulphuric acid. The cellulose turned black during dropwise addition of the test item. While mixing test item and cellulose, the mixture became hot and yielded a black granulate with white spots. No ignition was observed. After consultation of the national reference institute (BAM, Bundesanstalt für Materialprüfung) the test is not conductable as no mixture with cellulose can be tested, because the cellulose reacts with the test item to a mixture of charred cellulose containing only residues of test item and cellulose.The test item isn't considered as oxidizing based on its chemical structure.
