Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising liquids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2012
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.21 (Oxidising Properties (Liquids))
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- 10 min
- Sample tested:
- test mixture 1:1
- Parameter:
- mean pressure rise time
- Result:
- 17.6 s
- Sample tested:
- reference mixture with 65% nitric acid + cellulose (1:1 ratio)
- Parameter:
- mean pressure rise time
- Result:
- 5.8 s
- Interpretation of results:
- other: Since the time for the test substance mixture was much greater than that for the reference mixture, the test substance was considered to be a non-oxidizer.
Reference
The mean pressure rise time for the reference mixture (1 :1 w/w mixture of 65% w/w aqueous nitric acid and cellulose) was 5.8 seconds, while the pressure rise time for the test substance mixtures (1 :1 w/w mixture of the test substanceand cellulose) was a minimum 17.6 seconds. Since the time for the test substance mixture was much greater than that for the reference mixture, the test substance was considered to be a non-oxidizer.
Conclusion: Since the time for the test substance mixture was much greater than that for the reference mixture, the test substance was considered to be a non-oxidizer.
Description of key information
Not oxidising (EU Method A.21)
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Since the time for the test substance mixture was much greater than that for the reference mixture, the test substance was considered to be a non-oxidizer.
Justification for classification or non-classification
The available data on oxidising properties of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification: The substance is not oxidising.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
