8	2.5	2.5	98.1	10283

Remark: The pressure did not rise P_atm+ 2070 kPa for the assays No. 2 and 5 due to leaks. The assay No. 3 was performed but it was not taken into account as the result was not recorded.

 

Conclusion

The mean pressure rise times obtained with the three reference items / cellulose mixtures and with the test item / cellulose mixture were:

 

Mean pressure rise time (ms)
Reference items		Test item
50% perchloric acid solution	85	10975
40% aqueous sodium chlorate solution	395
65% aqueous nitric acid solution	2955

Applicant's summary and conclusion

Interpretation of results:

GHS criteria not met

Conclusions:

The mean pressure rise time obtained with the test item / cellulose mixture was higher than the mean pressure rise times obtained with the three mixtures of reference item / cellulose. The test item is thus not assigned to Division 5.1 and not classified as an oxidising liquid under CLP Regulation.

Executive summary:

2-Fluoronitrobenzene was tested for its oxidizing properties in compliance with United Nations Recommendations on the Transport of Dangerous Goods - Manual of Tests and Criteria - Fifth revised edition (2009) - Method O.2 (Part III, Section 34.4.2) and under GLP conditions. The mean pressure rise time obtained with the test item / cellulose mixture was compared to the mean pressure rise times obtained with the three mixtures of reference items / cellulose and demonstrated to be higher:

Mean pressure rise time (ms)
Reference items		Test item
50% perchloric acid solution	85	10975
40% aqueous sodium chlorate solution	395
65% aqueous nitric acid solution	2955

The test item was thus not assigned to Division 5.1 and not classified as an oxidising liquid under CLP Regulation.
