Oxidising properties
Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising liquids
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- weight of evidence
- Justification for type of information:
- Target and source substances are highly similar, both structurally and chemically.
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.21 (Oxidising Properties (Liquids))
- Deviations:
- no
- GLP compliance:
- no
- Contact with:
- powdered cellulose
- Duration of test (contact time):
- ca. 30 s
- Sample tested:
- test mixture (not specified)
- Remarks:
- migrated information
- Parameter:
- mean pressure rise time
- Result:
- >= 19.31 - < 29.55 s
- Sample tested:
- reference mixture (not specified)
- Remarks:
- migrated information
- Parameter:
- mean pressure rise time
- Result:
- >= 3.44 - < 4.93 s
- Interpretation of results:
- other: no oxidising properties
- Remarks:
- Migrated information
- Conclusions:
- Due to the fact that the 1:1 mixture, by mass, of test item and cellulose has a mean pressure rise time higher than that if 1:1 mixture, by mass, of 65% nitric acid and cellulose the test item has no oxidising properties.
- Executive summary:
Oxidising properties of uronium hydrogen sulphate were evaluated according to EU guideline A.21.
It was concluded that the test item has no oxidising properties.

Additional information
Justification for classification or non-classification
Data are conclusive for oxidising properties, but not sufficient for classification according to CLP criteria (Regulation (EC) No 1272/2008).
No classification is proposed for oxidising properties according to CLP.
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).
