Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Administrative data
Link to relevant study record(s)
- Endpoint:
- oxidising solids
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- UN Manual of Tests and Criteria: Test O.1 (Test for oxidizing solids)
- Deviations:
- no
- GLP compliance:
- no
- Contact with:
- powdered cellulose
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- 3 s
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- mean burning time
- Result:
- 33 s
- Interpretation of results:
- other: Category 1 (strong oxidising solids) based on EU GHS criteria
- Conclusions:
- The test item is reported to have a mean burning time in the 4:1 sample-to-cellulose ratio (by mass) of 3 seconds.
- Executive summary:
Chromium trioxide is reported in the "Recommendations of the TRANSPORT OF DANGEROUS GOODS Manual of Tests and Criteria" from the United Nations (2009) in a table with examples of results. The test item is reported to have a mean burning time in the 4:1 sample-to-cellulose ratio (by mass) of 3 seconds. Therefore the solid is a substance with strong oxidising properties and because having a mean-burning time less than the mean burning time of a 3:2 mixture, by mass, of potassium bromate and cellulose (4 s) the substance has to be classified as category 1 with regard to its oxidising properties.

Description of key information
Chromium trioxide is reported in the "Recommendations of the TRANSPORT OF DANGEROUS GOODS Manual of Tests and Criteria" from the United Nations (2009) in a table with examples of results. The test item is reported to have a mean burning time in the 4:1 sample-to-cellulose ratio (by mass) of 3 seconds. Therefore the solid is a substance with strong oxidising properties and because having a mean-burning time less than the mean burning time of a 3:2 mixture, by mass, of potassium bromate and cellulose (4 s) the substance has to be classified as category 1 with regard to its oxidising properties.
Key value for chemical safety assessment
- Oxidising properties:
- yes
Additional information
Justification for classification or non-classification
The test item is reported to have a mean burning time in the 4:1 sample-to-cellulose ratio (by mass) of 3 seconds. Therefore the solid is a substance with strong oxidising properties and because having a mean-burning time less than the mean burning time of a 3:2 mixture, by mass, of potassium bromate and cellulose (4 s) the substance has to be classified as category 1 with regard to its oxidising properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
