Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 07 May 2018 to 28 May 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.17 (Oxidising Properties (Solids))
- Deviations:
- yes
- Remarks:
- Potassium bromate was used as a reference substance. Ignition source is an ignition wire. Train test not used. These deviations are not considered to affect the reliability of the study
- GLP compliance:
- yes
- Contact with:
- other: potassium bromate
- Duration of test (contact time):
- 3 min
- Key result
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Key result
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- > 180 s
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The test item was concluded to have no oxidising properties
- Executive summary:
The full test procedure specified in EC A.17 was performed to monitor the oxidising properties of the test substance.
Based on the results obtained it was concluded that the test item has no oxidising properties and is therefore not classified as a Division 5.1 substance.
Reference
The burning rates of the test item and reference mixtures are given in Table 1 and Table 2, below.
The mean burning time of both test item mixtures was more than the mean burning time of the 3:7 (w/w) reference mixture. According to this, the test item has no oxidising properties.

Description of key information
Not oxidising; EC A.17; Reingruber, E. M. (2018)
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
The oxidising properties of the substance were assessed in accordance with the EC. A.17 guideline.
Based on the results obtained it was concluded that the test item has no oxidising properties and is therefore not classified as a Division 5.1 substance.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
