Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.21 (Oxidising Properties (Liquids))
- Deviations:
- no
- GLP compliance:
- not specified
- Contact with:
- other: cellulose
- Key result
- Sample tested:
- test mixture as specified
- Remarks:
- mixtures of the sample with cellulose (ratio 1 : 1)
- Parameter:
- mean pressure rise time
- Result:
- 6 850 ms
- Remarks on result:
- other: calculated from given data (see Table below), mean, n=5
- Sample tested:
- reference mixture as specified
- Remarks:
- Reference: 65 % Nitric acid + cellulose (1 : 1 ratio)
- Parameter:
- other: pressure rise time of reference mixture
- Result:
- 2 550 ms
- Remarks on result:
- other: single value
- Interpretation of results:
- GHS criteria not met
- Remarks:
- no oxidising properties
- Conclusions:
- 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).
- Executive summary:
Heitkamp, 2009, Study No.: 2009/01371e
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).
Reference
3 -nitrotoluene was found "not to have oxidising properties" after the following results
were obtained:
Test run | Sample amount | Maximum pressure | Time for pressure rise from 690 kPa to 2070 kPa | Remarks |
1 | 2,5 g | 2688 kPa | 6875 ms | No spontaneous ignition |
2 | 2,5 g | 2750 kPa | 5250 ms | No spontaneous ignition |
3 | 2,5 g | 2688 kPa | 8125 ms | No spontaneous ignition |
4 | 2,5 g | 2844 kPa | 7875 ms | No spontaneous ignition |
5 | 2,5 g | 2625 kPa | 6125 ms | No spontaneous ignition |
| 2,5 g | 2594 kPa | 2550 ms | Reference: 65 % Nitric acid + cellulose (1 : 1 ratio)
|
In all cases, the burning time of the m-Nitrotoluene / cellulose mixtures was found to be considerably longer than the reference mixture. Since no spontaneous ignition was observed either, m-Nitrotoluene was found to have no oxidising properties.

Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
