- Key result
- Sample tested:
- test mixture (not specified)
- Remarks:
- migrated information
- Parameter:
- maximum burning rate
- Result:
- 2.5 other: mm/s (migrated information)
- Remarks on result:
- other: Max burning mixture: 40% test substance. On 90% concentration of test substance/cellulose a flame shot across the sample in < 1 s.
- Interpretation of results:
- other: oxidising: maximum burning rate equal or higher than reference mixture
- Remarks:
- Migrated information
- Conclusions:
- Under the conditions of the test, NMMO was observed to be oxidising.
- Executive summary:
Oxidising properties of the test item were determined according to EU Method A.17. Under the conditions of the test, NMMO was observed to be oxidising.
Reference
Results of preliminary screening test:
- Reaction of reference sample: vigorous, 40 seconds of burning time, sample burnt with a medium green/blue flame
- Reaction of test sample: moderate, 162 seconds of burning time, sample burnt with a medium orange flame
The burning time of NMMO was greater than that of the reference sample in the preliminary screening test. Therefore it was necessary to complete the full train test.
Nine ratios were tested (containing 10 to 90% test substance). Tha ratio's with 10%, 20% and 90% had a burning rate of 1.0, 1.4 and 1.4 mm/s, respectively. All other ratio's showed a burning rate higher than the maximum burning rate of the reference mixture.
Description of key information
From a GLP study in accordance with the EC A.17 test method, NMMO was concluded to have oxidising properties (Younis, 2012).
Key value for chemical safety assessment
- Oxidising properties:
- oxidising
Additional information
Justification for classification or non-classification
From a GLP study in accordance with the EC A.17 test method, NMMO was concluded to have oxidising properties (Younis, 2012).
CLP: in general, substances that are classified as oxidising solids according to DSD will also meet the criteria for GHS classification according to CLP. However, assignment of a hazard category is not possible based on the EC A.17 test. As NMMO has no exposive properties, category 1 is anticipated to result in over-classification. Therefore, it is proposed to classify NMMO as a category 2 oxidising solid with hazard statement H272: May intensify fire; oxidiser.
