Applicant's summary and conclusion

Interpretation of results:
other: no oxidising properties
Remarks:
Migrated information
Executive summary:

A test conducted according to the Guideline EC A.21 showed that the mean pressure rise time for 3-nitrotoluene (6850 ms; five run tests) was longer than the pressure rise time for the reference substance (65% nitric acid, 2550 ms; single value). Furthermore, no spontaneous ignition was observed. Therefore, 3-nitrotoluene was found to have no oxidising properties (Currenta 2009).
