Test results (Oxidising solids)open allclose all
- Sample tested:
- 1:1 sample-to-cellulose ratio
- Parameter:
- burning rate
- Result:
- > 180 s
- Sample tested:
- 4:1 sample-to-cellulose ratio
- Parameter:

- Result:
- > 180 s
Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The mean burning rates (t1 and t2 > 180 s) of the 4:1 and the 1:1 mixing ratio of potassium bromate to cellulose are greater than the mean burning rates of the 3:7 mixing ratio of potassium bromate to cellulose (R1= 116 s).
Based on the test results and according to the criteria of the UN Recommandations on the Transport of Dangerous Goods Manual of Tests and Criteria, the test substance potassium chromate is not assigned to Class 5.1 "Oxidizing solids" of the International Dangerous Goods Regulations and also not to the hazard class "Oxidizing solids" of Regulation (EC) 1272/2008 (ELP Regulation) or the GHS.
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.
